Medical, OB/GYN

A diabetic patient who is conscious, able to swallow, and has an altered mental status with likely low blood sugar should receive:

  • a.Nitroglycerin
  • b.Aspirin
  • c.Activated charcoal
  • d.Oral glucose

A conscious diabetic with a protected airway and suspected hypoglycemia is treated with oral glucose. The patient must be able to swallow and protect the airway to receive anything by mouth.

Medical, OB/GYN

The classic signs of a stroke can be quickly screened using:

  • a.The Cincinnati Prehospital Stroke Scale (facial droop, arm drift, speech)
  • b.The Glasgow Coma Scale, scoring eye, verbal, and motor response
  • c.The rule of nines, which divides the body into percentages
  • d.OPQRST alone, the mnemonic used to characterize pain

The Cincinnati Prehospital Stroke Scale checks for facial droop, arm drift, and abnormal speech, and any one abnormal finding suggests a possible stroke and the need for rapid transport. The Glasgow Coma Scale grades overall level of consciousness rather than screening for stroke, the rule of nines estimates burn area, and OPQRST is a way to describe pain.

Medical, OB/GYN

Where the EMT's scope permits, for a patient having a severe allergic reaction (anaphylaxis) with prescribed medication available, the EMT may assist with:

  • a.A tube of oral glucose
  • b.Activated charcoal by mouth
  • c.Chewable aspirin tablets
  • d.An epinephrine auto-injector

Anaphylaxis is treated with epinephrine, and an EMT may assist a patient with their own prescribed auto-injector where protocol allows. Epinephrine reverses the airway swelling and low blood pressure caused by the reaction. Oral glucose treats low blood sugar, activated charcoal is used for some ingested poisons, and aspirin is used for suspected cardiac chest pain.

Medical, OB/GYN

An epinephrine auto-injector is most commonly injected into the:

  • a.Upper arm muscle
  • b.Buttock or hip area
  • c.Lateral (outer) thigh
  • d.Abdomen or flank

The epinephrine auto-injector is delivered into the outer thigh muscle, which can be done through clothing and allows rapid absorption. The upper arm, the buttock, and the abdomen are not injection sites for an auto-injector.

Medical, OB/GYN

The most important consideration before giving any oral medication or glucose is:

  • a.The patient can swallow and protect their airway
  • b.Whether the patient has eaten recently
  • c.The patient's systolic blood pressure is normal
  • d.The patient has taken the medication before

Anything given by mouth requires the patient to be able to swallow and protect the airway, so an unresponsive or severely altered patient should not receive oral medications or glucose. Recent food intake is worth recording in the history but does not by itself bar an oral medication, a normal blood pressure is a check tied to drugs such as nitroglycerin rather than a general requirement for anything oral, and having taken the medication before says nothing about whether the patient can swallow it now.

Medical, OB/GYN

A tonic-clonic (grand mal) seizure is actively occurring. The EMT's priority is to:

  • a.Hold the patient still and place a padded object between the teeth to protect the tongue
  • b.Restrain the arms and legs firmly to stop the convulsive movements
  • c.Insert an oropharyngeal airway during the convulsion to keep the airway open
  • d.Protect the patient from injury and manage the airway, without forcing anything into the mouth

During an active tonic-clonic seizure, protect the patient from injury and manage the airway, but do not restrain the limbs and do not force anything between the teeth. Objects placed in the mouth risk broken teeth, airway obstruction and bitten fingers, forcible restraint can cause fractures and dislocations, and an oral airway cannot be placed safely against clenched jaws. After the seizure, place the patient in the recovery position and give oxygen as needed.

Medical, OB/GYN

Activated charcoal may be indicated (per protocol/medical direction) for:

  • a.Certain oral poisonings in an alert patient who can protect the airway
  • b.Ingestion of a petroleum distillate such as gasoline or kerosene
  • c.Ingestion of a strong acid or alkali such as drain cleaner
  • d.Any unresponsive poisoning patient, to bind the drug early

Activated charcoal can bind some ingested poisons in an alert patient able to protect the airway, when directed by protocol or medical control. It is withheld after petroleum distillates because vomiting and aspiration injure the lungs worse than the swallowed product, after strong acids and alkalis because it does not bind them and it obscures the view for later endoscopy, and in patients with a decreased level of consciousness because they cannot protect the airway.

Medical, OB/GYN

A postictal patient (after a seizure) is typically:

  • a.Ready to walk and refuse care
  • b.Combative and requiring restraint by default
  • c.Confused, drowsy, and gradually improving
  • d.Fully alert immediately with no confusion

The postictal phase after a seizure involves confusion, drowsiness, and gradual recovery of orientation. Support the airway, provide reassurance, and monitor as the patient recovers.

Medical, OB/GYN

Time of symptom onset is especially critical to determine and report in patients with suspected:

  • a.A minor sprain
  • b.Motion sickness
  • c.Stroke
  • d.A common cold

Knowing when stroke symptoms began determines eligibility for time-sensitive treatments like clot-dissolving therapy. EMTs should establish and clearly report the last-known-well time.

Medical, OB/GYN

The mnemonic SAMPLE is used to gather a patient's:

  • a.The percentage of body surface burned, using the rule of nines
  • b.History (Signs/symptoms, Allergies, Medications, Past history, Last intake, Events)
  • c.The level of responsiveness, using Alert, Verbal, Painful, Unresponsive
  • d.The character of the pain: onset, quality, region, severity and time

SAMPLE stands for Signs and symptoms, Allergies, Medications, Pertinent past history, Last oral intake, and Events leading up to the call, giving a structured medical history. Burned body surface is estimated with the rule of nines, level of responsiveness is graded with AVPU, and the character of pain is drawn out with OPQRST.

Medical, OB/GYN

The OPQRST mnemonic is primarily used to assess:

  • a.The characteristics of pain or a chief complaint
  • b.The patient's past medical history and allergies
  • c.The adequacy of the airway and breathing
  • d.The extent of burns on the body surface

OPQRST (Onset, Provocation, Quality, Region and radiation, Severity, Time) explores the nature of pain or a chief complaint and helps characterize symptoms such as chest or abdominal pain. Past history and allergies come from SAMPLE, airway and breathing are judged in the primary assessment, and burn extent is estimated with the rule of nines.

Medical, OB/GYN

A woman in her third trimester complains of dizziness when lying flat on her back. The best position is:

  • a.Left lateral recumbent (tilted onto her left side)
  • b.Sitting fully upright with the legs dependent
  • c.Supine with the legs elevated (Trendelenburg)
  • d.Right lateral recumbent, onto her right side

Late in pregnancy the uterus can compress the inferior vena cava when the mother lies supine, cutting venous return and causing dizziness and hypotension. Because the vena cava lies to the right of the spine, tilting her onto the left side lifts the uterus off it. Turning onto the right side does far less, sitting upright does not address caval compression, and raising the legs while she stays flat leaves the uterus resting on the vessel.

Medical, OB/GYN

During normal childbirth, once the infant's head delivers, the EMT should:

  • a.Apply firm traction to the head to speed the delivery
  • b.Clamp and cut the cord before the shoulders deliver
  • c.Hold the head back until the ambulance reaches a hospital
  • d.Support the head and check whether the cord is around the neck

As the head delivers, support it gently and check for a nuchal cord (umbilical cord around the neck). Never pull on the infant; allow the body to deliver with the contractions. Pulling on the head can injure the infant's neck and brachial plexus, and cutting the cord before the body is out removes the infant's only source of oxygen while the chest is still compressed. Holding the head back to reach a hospital does not stop labor and risks injury to both mother and infant.

Medical, OB/GYN

The first priority for a newborn immediately after delivery is to:

  • a.Clamp and cut the umbilical cord before doing anything else
  • b.Suction the mouth and nose deeply before drying and warming
  • c.Dry, warm, position, and stimulate the newborn, keeping the airway clear
  • d.Check a blood glucose and give oral glucose if it is low

A newborn is dried, kept warm, positioned, and stimulated, with the airway cleared as needed, because preventing heat loss and getting the infant breathing are the immediate priorities. Cord clamping can wait until the infant is breathing and warm, deep suctioning is not routine and can provoke bradycardia, and glucose is not part of immediate newborn care in the field.

Medical, OB/GYN

A patient exhibiting a behavioral emergency who is a potential danger requires the EMT to prioritize:

  • a.Applying physical restraints to every such patient on arrival
  • b.Leaving the patient alone in a quiet room until they calm down
  • c.Completing a full head-to-toe physical exam before anything else
  • d.Scene safety and their own and the patient's safety, requesting help as needed

Behavioral emergencies require attention to scene safety first, protecting the crew and the patient and summoning law enforcement or extra resources as needed. Restraint is a last resort for a patient who is a danger, applied only within local policy, leaving a potentially dangerous patient unattended abandons them and risks harm to them or to others, and a detailed physical exam is not possible until the situation is controlled.

Medical, OB/GYN

Fruity (acetone) breath odor, deep rapid breathing, and excessive thirst in a diabetic suggest:

  • a.A stroke causing an irregular breathing pattern
  • b.Hyperglycemia / diabetic ketoacidosis (high sugar)
  • c.Hypoglycemia from a missed meal after insulin
  • d.An allergic reaction with airway involvement

Fruity breath, deep rapid (Kussmaul) breathing, and thirst point to high blood sugar and diabetic ketoacidosis, which develops gradually and requires oxygen support and transport. Low blood sugar instead comes on quickly with pale, sweaty skin and no fruity odor, a stroke produces focal deficits such as one-sided weakness or speech loss rather than thirst, and an allergic reaction brings hives, swelling and wheezing.

Medical, OB/GYN

Which set represents normal adult vital sign ranges?

  • a.Pulse 40 to 60, respirations 4 to 8, systolic BP about 60 to 80
  • b.Pulse 20 to 40, respirations 40 to 50, systolic BP about 40 to 60
  • c.Pulse 60 to 100, respirations 12 to 20, systolic BP roughly 90 to 140
  • d.Pulse 120 to 160, respirations 30 to 40, systolic BP about 70 to 90

A typical resting adult has a pulse of 60 to 100, respirations of 12 to 20, and a systolic blood pressure roughly in the 90 to 140 range. Values well outside these suggest a problem requiring assessment. The fast pulse and fast respiratory rate in one of the other sets are closer to what is expected in an infant than in an adult, and the remaining sets pair a slow pulse and slow breathing with a systolic pressure low enough to signal shock.

Medical, OB/GYN

A patient who responds only when you pinch their shoulder but does not respond to your voice is classified on the AVPU scale as:

  • a.Alert and following commands
  • b.Responsive to Painful stimulus
  • c.Responsive to Verbal stimulus
  • d.Unresponsive to all stimuli

AVPU stands for Alert, Verbal, Painful, Unresponsive. A patient who reacts only to a painful stimulus is scored as 'P' (Painful). An alert patient is awake and interacting before you touch them, and a verbal patient reacts when spoken to, which this patient did not. Unresponsive is reserved for a patient who does not react to a painful stimulus at all, so any reaction to the pinch rules it out.

Medical, OB/GYN

Cool, clammy skin in a diabetic patient with a rapid onset of altered mental status most often indicates:

  • a.Dehydration from vomiting
  • b.Slowly rising blood sugar
  • c.A brief fainting episode
  • d.Low blood sugar (hypoglycemia)

Hypoglycemia commonly causes cool, clammy, sweaty skin with rapid onset of altered mental status. If the patient can swallow, oral glucose is indicated. A rising blood sugar builds over hours to days and usually presents with warm, dry skin and thirst rather than this sudden picture. Dehydration and a simple faint do not explain mental status that stays altered, and treating either one first delays the sugar this patient needs.

Medical, OB/GYN

A patient with difficulty breathing and a history of asthma is prescribed a metered-dose inhaler. Under a typical EMS protocol with medical direction, the EMT may:

  • a.Give the patient a family member's inhaler if it is the same drug
  • b.Withhold all help because giving medication is outside the EMT role
  • c.Assist the patient in using their own prescribed inhaler per protocol
  • d.Give oral glucose, which relaxes the airway during an attack

EMTs may help a patient self-administer their own prescribed inhaler for respiratory distress, following local protocol and medical direction. Confirm the medication, dose, and expiration and that it is prescribed to that patient. An inhaler prescribed to someone else is not that patient's medication, whatever the label says, and refusing to help at all misreads the assisting role that protocols grant. Oral glucose treats low blood sugar and has no effect on bronchospasm.

Medical, OB/GYN

Severe lower abdominal or shoulder pain, dizziness, and signs of shock in a woman of childbearing age with a missed period may indicate:

  • a.A muscle strain from lifting, with referred pain
  • b.A urinary tract infection with bladder pain
  • c.A possible ectopic pregnancy with internal bleeding
  • d.Ovulation pain in the middle of the cycle

A ruptured ectopic pregnancy bleeds internally and produces lower abdominal pain, shoulder pain from blood irritating the diaphragm, and shock, so it needs oxygen, shock care, and rapid transport. A muscle strain and ovulation pain do not cause shock, ovulation pain is also ruled out by the missed period, and a urinary tract infection typically brings burning on urination and fever rather than hypotension.

Medical, OB/GYN

The primary treatment an EMT provides for most poisonings by inhalation is to:

  • a.Enter immediately and begin ventilating the patient in place
  • b.Move the patient to fresh air and provide oxygen once the scene is safe
  • c.Administer activated charcoal to bind the inhaled toxin
  • d.Induce vomiting to clear the poison from the stomach

For inhaled poisons, first ensure scene safety, then remove the patient to fresh air and give high-concentration oxygen. Entering a contaminated atmosphere without the right protection and training simply produces a second patient. Activated charcoal binds some swallowed poisons and does nothing about a gas already in the lungs, and inducing vomiting is no longer used for poisoning by any route.

Medical, OB/GYN

A patient with a possible opioid overdose has slow, shallow breathing. The EMT's first priority is to:

  • a.Check a blood glucose level before doing anything else
  • b.Walk the patient around to keep them awake
  • c.Support ventilation and oxygenation with a bag-valve mask
  • d.Give oral glucose between the cheek and gum

The immediate life threat in opioid overdose is respiratory depression, so support ventilation with a bag-valve mask and oxygen first. Naloxone may follow where protocol allows, but airway and breathing come first. Walking a patient does not restore respiratory drive, anything placed in the mouth risks aspiration in a patient who cannot protect the airway, and a glucose reading, while worth obtaining, does not treat hypoventilation.

Medical, OB/GYN

During delivery, if the umbilical cord presents first (prolapsed cord), the EMT should:

  • a.Position the mother to relieve pressure (knees to chest or hips elevated), keep pressure off the cord, and transport rapidly
  • b.Have the mother stand and walk to the ambulance so that gravity moves the baby down and delivery progresses
  • c.Gently pull on the cord to move it aside, then deliver the baby normally on the scene and clamp the cord
  • d.Push the cord back into the birth canal, hold it in place, and wait for the head to deliver on its own

A prolapsed cord is squeezed between the presenting part and the pelvis and cuts off the baby's oxygen supply, so relieve the pressure by positioning the mother hips-up or knees-to-chest, gently keep the presenting part off the cord, and transport immediately. Standing and walking increases the pressure on the cord, pulling on the cord can tear it or shear the placenta, and pushing it back inside does not relieve the compression while the delay costs the baby oxygen.

Medical, OB/GYN

A patient reporting a sudden severe headache, described as the worst of their life, with vomiting should be evaluated for:

  • a.Low blood sugar only
  • b.Motion sickness
  • c.A simple tension headache to ignore
  • d.A possible stroke or brain bleed

A sudden severe headache, often called the worst of one's life, can indicate bleeding in the brain and is a possible stroke. This requires oxygen support, monitoring, and rapid transport.

Medical, OB/GYN

Hives, itching, swelling of the face and tongue, and wheezing after a bee sting indicate:

  • a.A systemic allergic reaction possibly progressing to anaphylaxis
  • b.Hypoglycemia brought on by the stress of being stung
  • c.An asthma attack triggered by exertion in the heat
  • d.A local reaction confined to the area of the sting

Hives away from the sting site, facial and airway swelling, and wheezing are signs of a body-wide response, which marks a systemic allergic reaction that may become anaphylaxis. Prepare to assist with epinephrine and support the airway and breathing. A local reaction stays confined to the sting site, asthma alone does not cause hives or facial swelling, and low blood sugar produces altered mental status and sweating rather than hives.

Medical, OB/GYN

A patient having a seizure that does not stop, or repeated seizures without regaining consciousness, is called:

  • a.A febrile seizure caused by a high temperature
  • b.A postictal state following a single seizure
  • c.A simple partial seizure with awareness intact
  • d.Status epilepticus, a life-threatening emergency

Status epilepticus is a prolonged seizure, or repeated seizures without recovery of consciousness in between, and is life-threatening because of the hypoxia it produces. It requires airway support, oxygen, and rapid transport for definitive treatment. A postictal state is the recovery period after a seizure has already stopped, a febrile seizure is a brief seizure in a young child with a fever, and a simple partial seizure involves one part of the body with awareness intact.

Medical, OB/GYN

Nitroglycerin assists a cardiac patient primarily by:

  • a.Dilating blood vessels to reduce the heart's workload
  • b.Constricting blood vessels to raise blood pressure
  • c.Dissolving a clot already in a coronary artery
  • d.Slowing the heart rate to reduce oxygen demand

Nitroglycerin dilates blood vessels, reducing the workload on the heart and improving blood flow to the heart muscle. Because that same dilation lowers blood pressure, adequate pressure must be confirmed before assisting. It does not constrict vessels, it does not dissolve a clot that has already formed (that is the work of hospital fibrinolytics or catheter treatment), and it does not slow the heart rate.

Medical, OB/GYN

A 24-year-old with type 1 diabetes is unresponsive after taking her usual insulin and skipping meals. She has snoring respirations and no gag reflex. Under the standard EMT scope of practice in most states, the crew should:

  • a.Open the airway, ventilate as needed, and transport rapidly
  • b.Administer 25 g of dextrose intravenously, the definitive treatment for hypoglycemia at every EMS level
  • c.Place oral glucose gel between her cheek and gum, since buccal absorption does not require the patient to swallow
  • d.Insert an oral airway before placing the glucose gel

An unresponsive patient with no gag reflex must receive nothing by mouth, so opening the airway, ventilating as needed and transporting rapidly is what the EMT scope offers here. Oral glucose gel is the tempting choice because it is described as absorbing through the mucosa, but it is still a bolus of gel in the mouth of a patient who cannot swallow or protect her airway, and inability to swallow is a stated contraindication. An oral airway holds the tongue forward but does nothing to stop aspiration, so it does not make gel safe, and intravenous dextrose requires vascular access and sits above the EMT level in essentially every system.

Medical, OB/GYN

A conscious patient with a history of diabetes is confused but can follow simple commands and swallow. No blood glucose reading is available and the crew cannot tell whether the sugar is high or low. Under most EMS protocols the EMT should:

  • a.Withhold sugar until the hospital can measure a blood glucose, because giving glucose to a hyperglycemic patient can trigger ketoacidosis
  • b.Give oral glucose, since untreated hypoglycemia is the more immediate threat
  • c.Assume hyperglycemia, which is far more common in insulin users
  • d.Give oral glucose only once a glucometer reading confirms hypoglycemia

When the crew genuinely cannot tell high from low in a patient who is awake and able to swallow, most protocols favor giving oral glucose: hypoglycemia injures the brain within minutes, while a tube of glucose adds little to an already high sugar over a short transport. Withholding sugar until the hospital can measure it is the strongest competing choice, but ketoacidosis develops over hours to days and is not set off by one dose of oral glucose. Requiring a meter reading first is reasonable when a meter is at hand, but none is available here and treatment should not wait for one. Hyperglycemia being more common in insulin users does not make it the greater emergency.

Medical, OB/GYN

A patient stung by a wasp has itching and hives. Which additional finding means the reaction should be treated as anaphylaxis rather than a mild or localized allergic reaction?

  • a.Itching that began within five minutes of the sting
  • b.A previous reaction to a sting several years ago
  • c.Airway swelling or signs of shock
  • d.Hives spreading over more than half the body

Anaphylaxis is defined by involvement beyond the skin: respiratory compromise such as stridor, wheezing or tongue and throat swelling, or circulatory compromise such as hypotension, dizziness and weak pulses. Widespread hives are the most tempting finding because they look dramatic, but skin findings alone, however extensive, remain a skin reaction. Rapid onset and a prior reaction raise suspicion without meeting the definition; persistent vomiting and cramping abdominal pain, on the other hand, do count as a second body system.

Medical, OB/GYN

A patient in anaphylaxis improves dramatically minutes after an epinephrine auto-injector is used. He now feels well and asks to sign a refusal. The strongest medical reason to urge transport is:

  • a.The epinephrine must be reversed at the hospital with a medication that blocks its effects
  • b.Symptoms can return hours later in a biphasic reaction as the epinephrine wears off
  • c.Any patient given a medication by EMS is legally required to be transported
  • d.An auto-injector dose is too small for an adult and must be repeated

Anaphylaxis can recur hours after it appears to resolve, and epinephrine's effect is short-lived, so a patient who needed it requires evaluation and a period of observation. The belief that epinephrine has to be reversed at the hospital is the most common misconception in this scenario; there is no routine reversal agent and none is needed. A competent adult may still legally refuse, which is precisely why the crew has to explain the risk of a returning reaction rather than claim transport is mandatory, and the adult auto-injector delivers a full adult dose.

Medical, OB/GYN

Ten minutes after an epinephrine auto-injector was used, a patient's wheezing and facial swelling are worsening again, and a second auto-injector prescribed to the patient is on scene. In most EMS systems the EMT should:

  • a.Wait a full thirty minutes before any repeat dose, as that is the standard interval
  • b.Contact medical direction about a second dose
  • c.Give the second injection into the same thigh as the first
  • d.Withhold more epinephrine, since only a paramedic may give a repeat dose

Anaphylaxis that worsens again after one dose is exactly the situation in which a repeat dose may be authorized, and in most systems that authorization comes from on-line medical direction or an explicit standing order rather than the crew's own judgment. Withholding epinephrine on the belief that only paramedics may repeat it is both wrong and dangerous, since EMTs administer or assist with epinephrine in many systems. There is no universal thirty-minute rule; re-dose intervals are set by protocol, and the customary practice is to use the other thigh rather than reinjecting the same spot.

Medical, OB/GYN

A farm worker is found beside a pesticide sprayer with pinpoint pupils, heavy drooling and tearing, vomiting, and loss of bladder control. After the crew is protected and the patient has been decontaminated, the EMT's next priority is:

  • a.Give activated charcoal to bind the pesticide remaining in the stomach
  • b.Administer naloxone, since the pinpoint pupils point to an opioid overdose
  • c.Frequent suctioning and assisted ventilation with oxygen
  • d.Give oxygen by non-rebreather mask without suctioning

Organophosphate poisoning is a cholinergic crisis in which the airway fills with secretions and the patient dies of respiratory failure, so suctioning and ventilatory support come first. Naloxone is the tempting answer because of the pinpoint pupils, but it reverses opioids only and does nothing about the drooling, tearing and bronchial secretions; the antidotes are atropine and pralidoxime, which in most systems are carried at the ALS level or as auto-injectors an EMT may use only where protocol permits. A non-rebreather cannot push oxygen through an airway full of secretions and does not support failing ventilation, and activated charcoal has no role in an agent absorbed through skin and lungs.

Medical, OB/GYN

A family is found drowsy with headaches in a garage where a gasoline generator has been running. On room air, each of them has a pulse oximeter reading of 99%. The correct interpretation is:

  • a.A pulse oximeter cannot distinguish carboxyhemoglobin from oxyhemoglobin, so the reading is falsely reassuring
  • b.The high reading confirms adequate oxygenation, so carbon monoxide poisoning is unlikely
  • c.The reading is falsely high because carbon monoxide constricts the fingertip vessels, and warming the hand will correct it
  • d.Carbon monoxide drives the reading below 90%, so these numbers argue against exposure

A standard pulse oximeter reads carboxyhemoglobin much as it reads oxyhemoglobin, so a poisoned patient can show 99% while the blood carries very little usable oxygen. The history — an engine running in an enclosed space and several people with the same headache and drowsiness — therefore outweighs the number entirely. Carbon monoxide does not push the displayed saturation down, and it does not work by constricting the fingertip vessels; poor perfusion does make an oximeter unreliable, but that is not what is happening here. Only CO-oximetry or a hospital blood level measures it, and field care is removal from the source plus high-concentration oxygen.

Medical, OB/GYN

A 22-year-old is agitated and paranoid, with dilated pupils, drenching sweat, a heart rate of 148 and a blood pressure of 178/104, after taking an unknown drug. This pattern is most consistent with:

  • a.Opioid overdose, given the sweating and altered mental status
  • b.Benzodiazepine overdose with paradoxical excitement
  • c.Stimulant (sympathomimetic) intoxication
  • d.Organophosphate exposure, which also causes heavy sweating and agitation

Tachycardia, hypertension, dilated pupils, sweating and agitation form the sympathomimetic pattern seen with cocaine, amphetamines and similar drugs, and the EMT's concerns are hyperthermia, seizures and cardiac events. Organophosphate poisoning is the closest competitor because it also produces drenching sweat, but it constricts the pupils, slows the heart and floods the airway with secretions. Opioids cause pinpoint pupils with slow, shallow breathing, and sedatives depress rather than raise the heart rate and blood pressure.

Medical, OB/GYN

A worker has spilled a dry powdered industrial chemical across both forearms. After putting on gloves and eye protection, the EMT should first:

  • a.Wipe the powder away with a wet towel
  • b.Flush immediately with large volumes of low-pressure water for twenty minutes
  • c.Neutralize the powder with a mild acid or base before rinsing it away
  • d.Brush the dry powder off the skin, then flush with water

Brushing the dry chemical away first removes most of the agent and avoids the violent reaction some dry chemicals have with water; irrigation follows once the bulk of the powder is gone. Immediate flushing is the strongest competing answer, because copious irrigation is correct for liquid chemical exposures, and it is exactly the step that can make a water-reactive powder worse. Wiping with a wet towel adds water for the same reason and grinds the chemical into the skin, and neutralizing is never a field maneuver, since acid-base reactions release heat and can add a thermal burn to the chemical one.

Medical, OB/GYN

A man's slurred speech and right-sided weakness came on suddenly and then cleared completely over about twenty minutes. He now feels normal and does not want to be transported. The most accurate thing to tell him is:

  • a.Symptoms that clear within twenty-four hours rule out a clot, so seeing his doctor next week is enough
  • b.Because the weakness resolved on its own, this was almost certainly a migraine
  • c.This may have been a transient ischemic attack, a warning that a stroke may follow soon
  • d.He only needs to be seen if the weakness comes back on the same side

Deficits that resolve completely are typically a transient ischemic attack, and the risk of a completed stroke is highest in the days immediately afterward, so this patient needs urgent evaluation rather than reassurance. The most tempting error is treating resolution as proof that nothing happened; imaging and workup are what separate a transient attack from a small stroke, and no crew can make that call in the field. A competent adult may still refuse, so the crew should document the advice given and keep encouraging transport.

Medical, OB/GYN

A bystander describes a witnessed collapse. Which feature most suggests a seizure rather than simple fainting?

  • a.A few seconds of lightheadedness and nausea before the fall
  • b.Pale, sweaty skin with color returning within a minute
  • c.Prolonged confusion after the episode
  • d.A brief jerking of the arms and legs during the collapse

A postictal period of minutes to tens of minutes of confusion, sleepiness or headache is the most reliable discriminator, because a syncope patient is usually oriented again within a minute of lying flat. Brief jerking during the event is the strongest competing finding and the classic trap: convulsive syncope from cerebral hypoperfusion produces a few seconds of twitching, so movement alone does not settle the question and the recovery pattern matters more. A lightheaded, nauseated warning and pale sweaty skin with color returning quickly both fit ordinary vasovagal syncope.

Medical, OB/GYN

An EMT is treating a 70-year-old with new confusion and no sign of injury. Among the many causes of altered mental status, which one can an EMT most often both recognize and begin correcting in the field?

  • a.An expanding subdural hematoma from an unwitnessed fall days earlier
  • b.Low blood sugar, corrected with oral glucose
  • c.Uremia from kidney failure, recognized by the odor of the breath
  • d.Sepsis from a urinary tract infection

Hypoglycemia is the reversible cause an EMT is actually equipped for: it is common, the history and skin signs point to it, blood glucose measurement is within many EMT scopes, and oral glucose corrects it in a patient who can swallow. A subdural bleed is the strongest competing answer because it is common in older adults on blood thinners and changes the destination hospital, but nothing an EMT carries reverses it. Uremia and urinary sepsis also belong on the differential of new confusion in an older adult, yet an EMT can confirm and treat only the low sugar.

Medical, OB/GYN

A 76-year-old woke at 2 a.m. severely short of breath and is now wheezing. Which additional finding points to congestive heart failure rather than an asthma attack?

  • a.Swollen ankles and a need to sleep propped on several pillows
  • b.A forty-year smoking history with a barrel-shaped chest
  • c.A dry cough that started after he climbed the stairs
  • d.Wheezing heard loudest on exhalation through pursed lips, easing with a rescue inhaler

Dependent edema and orthopnea, along with waking at night gasping for air, are the fluid-overload findings of heart failure, and the wheeze of so-called cardiac asthma comes from fluid in the airways rather than bronchospasm. Pursed-lip exhalation that responds promptly to a bronchodilator is the hardest finding to separate, since heart failure patients can also wheeze, but prompt relief from a rescue inhaler points to reactive airway disease. A long smoking history with a barrel chest suggests COPD, and an exertional cough is nonspecific.

Medical, OB/GYN

A 4-year-old sits upright and very still, drooling, with a muffled voice, a high fever, and no cough. This presentation should raise the greatest concern for:

  • a.An aspirated foreign body
  • b.Epiglottitis
  • c.Croup before the barking cough appears
  • d.Asthma triggered by a viral illness

Drooling, a muffled voice, high fever, an absent cough and a child who insists on sitting still and upright form the classic epiglottitis picture. Croup is the strongest competitor because it is far more common at this age, but croup causes a barking cough with inspiratory stridor and usually a low-grade fever, and it does not typically produce drooling or a muffled voice, so an absent cough argues against croup rather than for an early stage of it. An aspirated foreign body can cause sudden distress and drooling but not a high fever, and asthma produces wheezing and lower airway findings. Management is what makes the distinction matter: keep the child calm and in a position of comfort with a caregiver, give blow-by oxygen only if it is tolerated, never inspect the throat or use a tongue depressor, and transport with airway equipment ready.

A 68-year-old man has sudden tearing abdominal pain radiating to his back, a pulsating mass above the umbilicus, and cool, mottled legs. The EMT should:

  • a.Treat this as renal colic, since pain radiating to the back is typical of a stone
  • b.Palpate the mass in all four quadrants to estimate how large it has become
  • c.Apply firm pressure over the mass to slow the internal bleeding
  • d.Avoid deep palpation, give oxygen if indicated, and transport rapidly

Tearing abdominal or back pain with a pulsatile mass and poor perfusion in the legs suggests an abdominal aortic aneurysm; nothing can be fixed in the field, so gentle handling, oxygen as indicated, shock care and rapid transport to a surgical center are the treatment. Kidney stone pain is the strongest competing explanation and can look identical at first, but a stone does not produce a pulsating mass or mottled legs, and treating this patient as low priority costs the diagnosis. Deep palpation and pressure over the mass risk rupture and are never used.

A patient reports several days of black, tarry, foul-smelling stools and now becomes dizzy when he stands up. This most likely indicates:

  • a.Hemorrhoidal bleeding at the anus, which turns black as the blood dries
  • b.A medication side effect rather than blood loss
  • c.Bleeding low in the colon, where stool darkens as it sits
  • d.Bleeding high in the digestive tract, such as from a stomach ulcer

Melena, meaning black tarry foul stool, is blood that has been digested during a slow passage from the upper gastrointestinal tract, classically a peptic ulcer or esophageal varices, and the dizziness on standing says enough volume has been lost to matter, so this is a shock patient. Hemorrhoidal bleeding is the tempting answer, but blood from the anus arrives undigested and bright red, and the same holds for the lower colon: it is stomach acid and digestive enzymes, not time sitting in the bowel, that turn blood black. Iron tablets and bismuth medicines also darken stool, which is why the foul odor and the orthostatic symptoms are the findings that push this toward true blood loss.

Medical, OB/GYN

A man who missed his last two dialysis sessions is weak and short of breath. Which action is most appropriate?

  • a.Lay him flat with the legs raised to relieve the weakness
  • b.Take the blood pressure in the fistula arm, where the shunt gives a truer reading
  • c.Encourage him to drink water, since dehydration causes the weakness
  • d.Take the blood pressure in the arm without the fistula

The limb holding an arteriovenous fistula or graft is protected: no blood pressure cuff, no tourniquet and no venipuncture on that side, because pressure can clot the access the patient's life depends on. Missed dialysis leaves a patient volume overloaded and hyperkalemic, so shortness of breath here suggests pulmonary edema and he is at real risk of a lethal arrhythmia. That is also why laying him flat with the legs raised is the wrong instinct, since it shifts still more fluid into an already overloaded chest, and why encouraging him to drink is actively harmful. Sit him up, give oxygen as indicated, and transport promptly.

Medical, OB/GYN

An 82-year-old nursing home resident is newly confused and weak, with a respiratory rate of 26, a heart rate of 112, warm skin, and a normal temperature. The EMT should most suspect:

  • a.A stroke, since sudden confusion in an older adult usually means a bleed or clot
  • b.Dehydration, since the nursing home may have missed her fluids
  • c.Sepsis, since older adults often fail to mount a fever
  • d.A reaction to a newly started medication

Older adults with serious infection often present with confusion, rapid breathing and a fast pulse and no fever at all, sometimes even with a low temperature, so a normal reading never excludes sepsis. Stroke is the tempting alternative because new confusion is dramatic, but strokes usually produce focal findings such as facial droop, one-sided weakness or speech loss rather than tachypnea and tachycardia. Dehydration and a new medication both belong on the list and are worth asking about, but they do not account for a respiratory rate of 26 with a heart rate of 112 and warm skin. Aging itself does not cause confusion: new confusion in an older adult is a symptom to be explained, not a baseline.

Medical, OB/GYN

A large man is combative and incoherent, sweating profusely and appearing not to feel pain. Once law enforcement and enough personnel are on scene and restraint has been decided on, the EMT should:

  • a.Secure him face down on the stretcher, which best protects the crew during the transport
  • b.Apply metal handcuffs yourself and remove them only at the hospital
  • c.Sandwich him between two long backboards to limit movement
  • d.Restrain him supine or on his side rather than prone, and monitor breathing

Prone and hog-tie restraint is the position associated with restraint asphyxia deaths, because the chest cannot expand against the stretcher in a patient who is already hyperthermic, acidotic and exhausted. Restrain face up or on the side with no weight on the back, keep airway and breathing under continuous watch, and expect sudden deterioration, including cardiac arrest. Sandwiching a patient between boards is the strongest competing answer because it looks like it simply controls movement, but it splints the chest for the same reason prone restraint kills. Handcuffing is a law enforcement function, and an officer with a key rides along whenever cuffs stay on.

Medical, OB/GYN

A runner collapses during a race on a hot, humid day. He is confused and combative, his skin is hot, and he feels extremely warm to the touch. The single most important field treatment is:

  • a.Slow cooling with a fan alone, to avoid shivering and rebound heating
  • b.Oral electrolyte drinks and rest in the shade until he improves
  • c.Sponge him with rubbing alcohol to speed evaporation
  • d.Immediate aggressive whole-body cooling

Altered mental status with a very high core temperature is heat stroke, and survival depends on how fast the temperature falls, so remove him from the heat, take off the clothing, and cool aggressively while transporting, using cold water immersion where it is available or wetting the skin with fans plus ice packs to the neck, armpits and groin. Cooling slowly to avoid shivering is the strongest competing answer, because shivering really does generate heat, but a delayed fall in core temperature is the far greater danger and shivering is managed rather than avoided. Alcohol sponging is a folk remedy that is absorbed through the skin and is not used, and nothing goes in the mouth of a confused patient, which rules out oral electrolyte drinks.

Medical, OB/GYN

A woman in active labor says the baby is coming. Which single finding most reliably tells the EMT to prepare to deliver on scene rather than transport?

  • a.Contractions about five minutes apart in a first pregnancy
  • b.The membranes rupturing as the crew arrived on scene
  • c.Crowning of the baby's head at the vaginal opening
  • d.A bloody show of mucus passed about an hour ago

Crowning, meaning the presenting part is visible and bulging at the perineum with each contraction, means delivery is happening now, and preparing to deliver where the crew stands is safer than transporting through the birth. Contraction timing is the closest competitor and is worth recording, but contractions five minutes apart in a first labor commonly leave hours to go. Ruptured membranes and bloody show mark the progress of labor without predicting how soon the baby will arrive.

Medical, OB/GYN

A woman at 34 weeks of pregnancy has a blood pressure of 168/110, marked swelling of the hands and face, a severe headache, and spots in her vision. Besides rapid transport, the EMT's most important action is:

  • a.Transport quietly on her left side and be prepared for a seizure
  • b.Have her walk out to the ambulance rather than wait for the stair chair
  • c.Keep her supine and flat for the whole transport
  • d.Give fluids and sugar by mouth for likely dehydration

This picture is severe preeclampsia, and the danger is an eclamptic seizure, so the EMT's contribution is minimizing stimulation with a quiet, dim, gentle ride while positioning her on her left side to keep the uterus off the vena cava, plus early hospital notification. Lying flat on the back is the closest competing position and is the trap here: at 34 weeks the uterus compresses the vena cava and drops cardiac output, which is why left lateral positioning is used instead. Exertion such as walking raises blood pressure rather than lowering it, and nothing goes by mouth for a patient who may seize or need urgent surgery.

Medical, OB/GYN

The placenta has delivered and the mother continues to bleed heavily. Under most EMS protocols the EMT should first:

  • a.Massage the uterus through the abdominal wall
  • b.Pack the vagina firmly with sterile gauze to tamponade the flow
  • c.Pull steadily on the cord stump to look for retained placenta
  • d.Nurse the newborn at the breast and transport without doing anything else

A boggy uterus that will not contract is the usual cause of postpartum hemorrhage, and firm fundal massage with a cupped hand is the field treatment that works. Putting the newborn to the breast is the strongest competing answer and is genuinely useful, because suckling releases oxytocin and helps the uterus clamp down, but it is slower and less reliable than massage, so massage comes first and nursing is added alongside it rather than instead of it. Packing the vagina is specifically contraindicated because it conceals ongoing blood loss and invites infection, and traction on the cord stump risks tearing it or inverting the uterus. Treat the mother for shock, save any tissue that passes, and transport.

Medical, OB/GYN

As the baby's head delivers, the EMT feels the umbilical cord looped around the newborn's neck. The first action should be:

  • a.Gently slip the cord over the baby's head
  • b.Push the head back slightly to take tension off the cord
  • c.Clamp the cord in two places and cut between the clamps at once
  • d.Support the head and transport at once

A nuchal cord is common and is usually handled by hooking a finger under it and easing it over the head so delivery continues normally. Clamping and cutting is the answer that feels decisive and is the strongest competitor, but it is reserved for a cord too tight to slip, because cutting ends the baby's oxygen supply before the chest has delivered and the newborn can breathe. Pushing the head back can injure mother and baby, and holding the delivery to transport does not stop labor.

Medical, OB/GYN

Which set lists the five components of the APGAR score?

  • a.Appearance, pulse, grimace, alertness and respiratory rate
  • b.Appearance, pulse, grimace, activity and respiration
  • c.Appearance, pulse, gestation, activity and tone
  • d.Airway, pulse, grimace, tone and respiration

APGAR stands for appearance meaning color, pulse, grimace meaning reflex irritability, activity meaning muscle tone, and respiration, each scored zero to two for a maximum of ten, and it is assessed one minute and five minutes after birth. The version substituting alertness and respiratory rate is the common misremembering: what is graded is the newborn's tone and its response to stimulation, not its wakefulness. The score documents the newborn's condition, but resuscitation is driven by breathing effort, heart rate and color and is never delayed to finish scoring.

Medical, OB/GYN

An EMT is assessing a responsive 58-year-old whose only complaint is chest tightness that began an hour ago. How does the secondary assessment of a medical patient like this normally differ from that of a patient with a significant mechanical injury?

  • a.It is focused on the system suggested by the complaint and driven by the history
  • b.It is a rapid full-body survey carried out before any history is taken from the patient
  • c.It is limited to vital signs, because a medical patient has nothing to find on examination
  • d.It is the same head-to-toe examination that every patient receives

For a responsive medical patient the history is the assessment: the complaint tells the EMT which body system to examine, so the exam is focused rather than head-to-toe. The rapid full-body survey is the strongest competitor and is genuinely correct for a significant injury mechanism or for an unresponsive medical patient, where no history is available and the crew has to search the body for clues instead. Giving every patient an identical head-to-toe examination spends time that a focused complaint does not justify, and confining the assessment to vital signs alone throws away findings such as leg swelling, an irregular pulse or crackles at the lung bases that change what the crew does next.

Medical, OB/GYN

A patient with difficulty breathing is being transported. Under the reassessment guidance taught in most EMS systems, how often should the EMT repeat the vital signs and reassess the patient?

  • a.Once on arrival
  • b.Every fifteen minutes
  • c.Only if his breathing changes noticeably
  • d.About every five minutes

The interval commonly taught is roughly every five minutes for an unstable patient and roughly every fifteen minutes for a stable one, and respiratory distress puts this patient in the unstable group. Fifteen minutes is the most tempting answer because it is a real number from the same rule, but it is the stable-patient interval and it can let a deterioration run unnoticed for a quarter of an hour. Waiting for the patient to announce a change is unreliable, because a tiring patient often goes quiet just before failing, and a single set of numbers recorded on arrival says nothing about the trend, which is the whole point of reassessment. The four options here are deliberately bare intervals so that no wording gives the answer away.

Medical, OB/GYN

A crew forms a general impression of a patient who is grey, sweaty and struggling to speak in full sentences, and decides this is a 'load and go' situation. For a medical patient, what does that decision mean in practice?

  • a.That the physical examination is skipped and only vital signs are recorded on the way in
  • b.That the ambulance is driven to the hospital with warning lights and the siren running
  • c.That on-scene time is kept short and most of the assessment happens during transport
  • d.That the patient is moved to the ambulance before the primary assessment is completed

Load and go describes limiting time on scene for a time-critical patient: the primary assessment and any immediate life-saving care are done where the patient lies, and the history, the focused exam and the reassessments are completed in the moving ambulance. Warning lights and siren are the closest competitor, and they often accompany the decision, but transport mode is a separate judgement that usually saves only a couple of minutes while raising crash risk, and plenty of load-and-go patients are driven in without them. Moving the patient before the primary assessment is finished is not load and go but the way an unmanaged airway or an uncontrolled bleed leaves the scene, and nothing about the decision licenses skipping the physical examination.

Medical, OB/GYN

Road noise in a moving ambulance makes it impossible to hear Korotkoff sounds, so an EMT takes the blood pressure by palpation instead. What does this technique give the EMT?

  • a.Both numbers, but each of them reads slightly lower than it would by auscultation
  • b.A mean arterial pressure
  • c.A diastolic reading only
  • d.A systolic reading only

Palpation detects the pressure at which the radial pulse reappears as the cuff deflates, and that is the systolic pressure; it is documented in a form such as 88 over P to show that no diastolic was obtained. The idea that both numbers come through, each a little low, is the common misconception and it is wrong for a specific reason: the diastolic is defined by hearing the sounds disappear, and there is nothing to feel at that moment. A palpated systolic does tend to run a few millimetres of mercury below the auscultated value, and no mean pressure can be derived by feel, so palpation is a legitimate technique when noise or motion defeats the stethoscope but the reading should be repeated by auscultation once conditions allow.

Medical, OB/GYN

A patient with a gastrointestinal bleed is pale, cold and clammy, with a thready radial pulse. The pulse oximeter reads 88% on one attempt and then will not pick up a signal at all. The EMT should:

  • a.Record 88% as accurate and titrate oxygen precisely to bring that number up to 94%
  • b.Treat the clinical picture, recognizing that poor perfusion makes the reading unreliable
  • c.Move the probe to a different finger and withhold oxygen until a stable number is displayed
  • d.Document that no reading was obtainable, which by itself confirms respiratory failure

A pulse oximeter needs a pulsatile arterial signal at the sensor, so shock, cold extremities and vasoconstriction make it read low or fail entirely, and a shocked patient gets oxygen and rapid transport on clinical grounds whatever the number says. Moving the probe is a reasonable troubleshooting step and is the strongest competing answer, but withholding oxygen while chasing a better waveform is the part that makes it wrong. A failed reading is a statement about perfusion at the fingertip rather than proof of respiratory failure, and a normal reading would not have excluded shock either, since a patient who has lost a large volume of blood can saturate the hemoglobin he has left perfectly well.

Medical, OB/GYN

An EMT checks orthostatic vital signs on a patient with several days of vomiting and diarrhea who is normotensive while lying down. What finding would suggest significant fluid loss?

  • a.A blood pressure that rises by a few points on standing, as gravity loads the leg veins
  • b.A pulse that stays within a few beats of the supine rate after standing for two minutes
  • c.A marked rise in pulse or fall in blood pressure on sitting or standing up
  • d.A respiratory rate that increases when the patient stands up

A hypovolemic patient can hold a normal pressure while lying flat and only reveal the deficit when the circulation is challenged by sitting or standing, which shows up as the pulse climbing or the pressure dropping; the thresholds usually taught are a systolic fall of about twenty millimetres of mercury or a pulse rise of about twenty beats per minute, and services differ on the exact cut-off. A pulse essentially unchanged after two minutes of standing is the reassuring result rather than the positive one, which is what a hurried candidate mistakes for a positive test. A small rise in pressure on standing is ordinary physiology, and respiratory rate is not part of the test. Orthostatic readings are not attempted on a patient who is already hypotensive, unstable or unable to stand safely.

Medical, OB/GYN

An unresponsive patient with no history of trauma has one pupil that is clearly larger than the other and slow to react to light. This finding should most raise concern for:

  • a.Hypoxia, as the oxygen level keeps falling
  • b.An opioid overdose, as the breathing slows
  • c.A lifelong difference in pupil size
  • d.Rising pressure inside the skull

A newly unequal, sluggish pupil in an unresponsive patient suggests pressure inside the skull compressing the nerve that controls that pupil, as happens with an expanding bleed or a large stroke, and it calls for airway support and rapid transport to a hospital with neurosurgical capability. A minority of people do have a small lifelong difference between their pupils, which is the genuinely tempting alternative, but that variation is slight, both pupils still react briskly, and it can never be assumed in a patient who cannot tell you it has always been that way. Hypoxia and opioids act on the pair rather than on one side: falling oxygen eventually dilates both pupils and opioids constrict both, so neither accounts for one large sluggish pupil.

Medical, OB/GYN

A 71-year-old has sudden right-sided weakness and slurred speech that began forty minutes ago. His blood glucose reads 104 mg/dL. What does that reading tell the EMT?

  • a.That the deficits come from a sugar too low for an older brain
  • b.That glucose should be given anyway, since sugar protects the brain in stroke
  • c.That hypoglycemia is excluded, so the patient is managed as a stroke
  • d.That glucometer readings are unreliable in stroke patients and should be disregarded

Checking the sugar matters because hypoglycemia is the great stroke mimic, and 104 mg/dL sits within the normal range, so the reading removes that explanation and leaves the crew with a stroke to transport urgently with a documented time of last known well. Giving glucose anyway is the most tempting error: raising the sugar of a patient who is not hypoglycemic does not protect brain tissue, and higher glucose in acute stroke is associated with worse outcomes. Age does not shift what counts as a normal glucose, and the reading is meaningful precisely because it is what rules the mimic out rather than something to disregard.

Medical, OB/GYN

An 84-year-old woman with long-standing diabetes has sudden weakness, nausea and shortness of breath that began while she was sitting quietly. She denies any chest pain at all. The EMT should treat this as a possible:

  • a.Gastrointestinal upset from something she ate
  • b.A panic attack brought on by anxiety
  • c.A heart attack
  • d.The normal effect of ageing on an 84-year-old

Older adults and people with diabetes frequently have a myocardial infarction without chest pain, presenting instead with sudden weakness, breathlessness, nausea, sweating, fainting or simply feeling unwell, so the absence of pain lowers the odds of the diagnosis being made rather than the odds of it being present. A digestive cause is the closest competitor because the nausea is prominent, and it is exactly the reasoning that gets these patients transported without urgency; anxiety is the other common misattribution and is not a diagnosis anyone can make in the field. New weakness in an older adult is a symptom that needs an explanation, never a normal feature of ageing. The four options are bare diagnoses on purpose, so none of them argues for itself.

Medical, OB/GYN

An EMT finds a confused patient alone at home with no history available. The home medicine bottles are glipizide, metformin and lisinopril. What is the most useful immediate conclusion?

  • a.Nothing can be concluded, as medication bottles are unverified
  • b.The patient is being treated for diabetes, so the blood sugar should be checked now
  • c.The metformin is the likely cause of the confusion, as it drives blood sugar very low
  • d.The lisinopril proves the confusion came from a blood pressure that fell too far

A medication list is often the only history available, and two oral diabetes drugs make hypoglycemia the first thing to check and the one cause of confusion an EMT can begin to correct in a patient who can protect his own airway and swallow. Blaming the metformin is the trap, and the distinction is worth knowing: sulfonylureas such as glipizide commonly cause hypoglycemia, while metformin taken on its own rarely does. Lisinopril treats blood pressure but does not by itself establish that a low pressure caused this episode, and bottles remain valuable evidence even though they are not proof of what was actually swallowed or when.

Medical, OB/GYN

A patient with abdominal pain speaks almost no English. Her nine-year-old son speaks both languages fluently and offers to translate. The best approach for the EMT is to:

  • a.Have the son translate throughout, since he is fluent and knows his mother's history
  • b.Ask a bilingual neighbour who has come in to translate instead
  • c.Use the service's interpreter line, addressing the patient directly
  • d.Skip the history and rely on the physical examination and the vital signs by themselves

A trained or telephone interpreter is the standard, because clinical questions about pain, bleeding, pregnancy or drug use are ones a young child cannot render accurately and should not be made to hear, and the EMT should keep looking at and speaking to the patient rather than to the interpreter. Using the son is the genuinely tempting option, and an adult family member is a reasonable stopgap when nothing else can be reached, but a nine-year-old is not. The neighbour is the harder call: better than the child, still an untrained stranger who will afterwards know the patient's private history, so she is a fallback and not the answer when an interpreter line exists. Abandoning the history altogether throws away the part of the assessment that matters most in a medical complaint.

Medical, OB/GYN

A 17-year-old collapsed briefly while sprinting at football practice on a warm day and is now alert with normal vital signs. His parents ask whether he really needs to go to hospital. The most important point is that:

  • a.Collapsing in warm weather during exercise is heat-related and needs only fluids and rest
  • b.Fainting during exertion suggests a cardiac cause and needs evaluation
  • c.A full recovery with normal vital signs means he can stay home
  • d.The brief jerking of his limbs during the collapse means epilepsy

Fainting that happens during exertion rather than after it is a recognized warning sign for structural heart disease or an arrhythmia in a young person, and normal vital signs afterwards are expected and reassure nobody, so this patient needs to be seen. Heat and exertion is the strongest competing explanation and it is common, but here it is a diagnosis of exclusion, and acting on it in the field is precisely how a cardiac cause gets missed in a young athlete. Brief jerking of the limbs is common in ordinary fainting from a short drop in cerebral blood flow and does not establish epilepsy.

Medical, OB/GYN

A patient has a blood pressure of 224/126 together with a severe headache, blurred vision and new confusion. Under a typical EMS protocol the EMT should understand that:

  • a.The reading alone defines the emergency, so a patient without symptoms is equally urgent
  • b.An extra dose of his own blood pressure tablet should be taken now to bring it down
  • c.Lying him head-down improves the blood flow to his brain and should be done during transport
  • d.The symptoms of organ injury make this urgent, and the EMT does not lower the pressure

What separates a hypertensive emergency from a merely high reading is evidence that organs are being injured, such as headache with visual change, confusion, chest pain, breathlessness or focal weakness, and field care under typical EMS protocols is calm handling, oxygen if indicated, monitoring and prompt transport rather than any attempt to bring the pressure down. The idea that the number by itself defines the emergency is the most common misconception, and it matters because a symptom-free patient with a similar reading is handled far less aggressively. Extra doses of home medication are not an EMT intervention and lowering a pressure too fast can itself cause a stroke, and a head-down position raises pressure inside an already stressed skull.

Medical, OB/GYN

A 20-year-old is breathing very fast after an argument and reports tingling in her fingers and around her mouth, with spasm of her hands. Her oxygen saturation is 100%. The EMT should:

  • a.Have her rebreathe into a paper bag until the tingling settles
  • b.Coach her breathing calmly while still looking for a medical cause
  • c.Treat the tingling and hand spasm as proof of anxiety
  • d.Withhold oxygen for the rest of the call because her saturation is already 100%

Reassurance and coaching a slower rate is the safe field response, but only alongside continued assessment, because pulmonary embolism, diabetic ketoacidosis, aspirin overdose, sepsis and myocardial infarction all present with fast breathing and can look like panic. Paper-bag rebreathing is the classic wrong answer and is no longer taught: it can cause dangerous hypoxia and has killed patients whose fast breathing turned out to be compensation for a serious illness. A saturation of 100% at this moment neither settles the cause nor licenses a decision to withhold oxygen for the remainder of the call, and the tingling and hand spasm come from the low carbon dioxide of overbreathing, whatever is driving the overbreathing.

Medical, OB/GYN

A 2-year-old began coughing forcefully while eating grapes. He is sitting up, crying loudly between coughs, and his color is normal. The EMT should:

  • a.Begin back blows and chest thrusts straight away
  • b.Sweep a finger through his mouth to remove the grape
  • c.Give abdominal thrusts until the grape comes out
  • d.Let him keep coughing and avoid upsetting him

A forceful cough, a loud cry and normal color mean air is moving, and a child's own cough clears an object better than anything a rescuer can do, so the crew keeps him calm in his parent's arms, gives oxygen if he tolerates it and transports while watching for deterioration. Abdominal thrusts are the strongest competitor, because they are indeed the right technique for a choking child over one year old, but only once the obstruction becomes complete and the child can no longer cough, cry or breathe. A blind finger sweep is specifically avoided in children because it commonly drives the object deeper, and back blows with chest thrusts are the sequence for an infant under one year, not for a two-year-old.

Medical, OB/GYN

A ventilator-dependent patient at home with a tracheostomy tube is in obvious distress and the ventilator's high-pressure alarm is sounding. His caregiver reports thick secretions all morning. Where the EMT's state scope and local protocol permit tracheostomy suctioning, the first action should be:

  • a.Seal the stoma with a dressing and ventilate by mask over the mouth and nose instead
  • b.Pull the tracheostomy tube out of the stoma so that the obstruction leaves with the tube
  • c.Disconnect the ventilator and ventilate through the tube with a bag-valve device
  • d.Suction the tracheostomy tube

A tube blocked by thick secretions is the most common cause of sudden distress in a tracheostomy patient, and a high-pressure ventilator alarm is what an obstruction between the ventilator and the lungs looks like, so clearing the tube by suction is the fix that addresses the cause. Note the qualifier in the stem: suctioning an established tracheostomy tube is within the EMT scope in many states and services and outside it in others, where the caregiver suctions or an ALS crew is required, so a candidate must know the local rule rather than a national one. Disconnecting and bagging through the tube is the strongest competitor and is the right next step if distress continues after suction, but forcing gas down a plugged tube does not move the plug. Ventilating over the mouth and nose is what a crew reaches for out of habit and can be useless here, because this patient breathes through the neck and the upper airway may be surgically separated from the lungs; if the tube cannot be cleared, ventilation is delivered at the stoma. Removing the tube is not the EMT's first move.

Medical, OB/GYN

While suctioning a patient, an EMT gets a splash of blood-tinged secretions into her unprotected eye. Under a compliant exposure control plan, she should:

  • a.Notify the on-duty officer first and wait for direction before flushing
  • b.Finish the shift and report it later only if she develops symptoms in the weeks that follow
  • c.Ask the receiving nurse whether the patient carries a bloodborne infection
  • d.Flush the eye with water at once, then report the exposure through her service

The bloodborne pathogens standard requires the employer to ensure that mucous membranes are flushed with water immediately or as soon as feasible after contact, and to make a confidential post-exposure medical evaluation available, so the sequence is flush first and report immediately afterwards. Reporting first and waiting for direction is the genuinely tempting order, because reporting feels like the compliance step, and it is wrong only on timing: the flush costs seconds, needs no permission, and every minute of delay leaves material on the conjunctiva. Waiting until the end of the shift, or until symptoms appear weeks later, forfeits both post-exposure prophylaxis, whose value depends on starting quickly, and the documentation that supports any later claim. The source patient's status is established through the exposure process, not by a crew member asking a nurse at the bedside.29 CFR 1910.1030

A patient with several weeks of cough, night sweats and weight loss is being transported for suspected tuberculosis. Which respiratory protection is appropriate?

  • a.Gowns and gloves for the crew, with no mask needed
  • b.A surgical mask for the crew and one for the patient
  • c.A fitted N95 respirator for the crew
  • d.A fitted N95 respirator on the patient, with a surgical mask for the crew

Tuberculosis spreads by airborne particles small enough to stay suspended in the air, so the crew needs a fit-tested N95 or better, the patient wears a surgical mask to contain what he exhales, and the ambulance is ventilated with outside air. Surgical masks all round is the answer that catches candidates who remember droplet precautions for influenza, and it fails for a specific reason: a surgical mask does not seal to the face and does not filter fine airborne particles, which makes it the right item for the patient and the wrong one for the crew. Reversing the two puts the harder-to-breathe-through respirator on a sick patient and leaves the crew unprotected, and gowns and gloves guard against a contact route this organism does not use.

Medical, OB/GYN

A 19-year-old with sickle cell disease has severe pain in both thighs and his back, of the kind he gets with a crisis. He is alert, with a fever and a mild cough. Appropriate EMT care includes:

  • a.Keeping him warm, giving oxygen if he is hypoxic, and transporting
  • b.High-flow oxygen for every sickle cell crisis regardless of the saturation
  • c.Treating his pain report as drug-seeking and limiting care
  • d.Ice packs on the painful limbs to reduce the inflammation

Warmth, oxygen when the patient is hypoxic or working to breathe, gentle handling, a position of comfort and prompt transport for fluids and analgesia are the supportive measures that fit the EMT scope in a sickling crisis. Oxygen for every crisis regardless of the number is the closest competitor and is worth being precise about: hypoxia does promote sickling, so a hypoxic patient must be oxygenated, but routinely giving oxygen to a patient who is already well saturated has not been shown to shorten a crisis, and the trigger is therefore the saturation and the work of breathing rather than the diagnosis. Ice is the specific trap, because cold causes vasoconstriction and can extend the sickling and the pain rather than relieve it. Fever with cough in a sickle cell patient raises the possibility of acute chest syndrome, which is life-threatening and makes this a time-critical transport, and treating a patient's reported pain as drug-seeking is a well-documented bias that delays care in exactly this population.

An 80-year-old on an anticoagulant struck her forehead on a cupboard door. She never lost consciousness, is fully oriented, has no headache, and wants to stay home. The EMT should tell her that:

  • a.Not losing consciousness and having a clear head now rules out any dangerous bleeding
  • b.Bleeding can start hours later on this medication, so she should be seen today
  • c.A check with her own doctor sometime in the coming week would be perfectly adequate here
  • d.She should stop the anticoagulant tonight to make bleeding less likely

Anticoagulants let a small tear go on bleeding slowly, so a patient can look and feel entirely normal for hours and then deteriorate, which is why even a minor head strike on these drugs warrants same-day assessment and imaging and why this refusal needs a careful conversation, a clear warning about what to watch for, and documentation. The belief that a clear examination and no loss of consciousness excludes a bleed is exactly the reasoning that leads crews to accept a refusal too easily, and it is the strongest competitor here. Deferring to a routine appointment next week misses the window in which a growing bleed can be found and treated, and an EMT never advises a patient to alter a prescribed medication, since stopping an anticoagulant carries its own risk of clot or stroke.

A patient receiving chemotherapy has an implanted chest port and is being transported for weakness. Under the EMT scope of practice used in the United States, the EMT should:

  • a.Flush it with sterile saline so that it does not clot off en route
  • b.Draw a blood sample from it for the hospital laboratory
  • c.Leave it alone
  • d.Access it with the home nurse's telephone permission

Accessing, flushing or drawing from a central venous catheter or an implanted port sits outside the EMT scope under the National EMS Scope of Practice Model, which gives the EMT no vascular access skills at all; the device is left undisturbed, the site is looked at and protected, and any vascular access needed is established by a provider whose scope includes it. Permission from a home nurse, or from the patient, is the tempting escape and it does not work, because consent cannot enlarge a scope of practice that the state has defined. Ports are also a route for bloodstream infection, so redness, swelling or tenderness at the site is worth reporting in the handover for a patient who is on chemotherapy and now weak.

An EMT is called for a woman who reports having been sexually assaulted an hour ago. She has minor injuries and is alert. Alongside her medical care, the crew should:

  • a.Carry out a detailed examination of the genital area and record the findings
  • b.Discourage washing or changing clothes, and handle clothing as little as possible
  • c.Encourage her to shower and change into clean clothes before transport
  • d.Hold off on all treatment until officers have arrived and finished interviewing her fully

Washing, changing clothes, drinking or using the toilet can destroy evidence, so the crew explains why and asks her to wait, disturbs clothing only as far as treatment requires, and puts any clothing that must be removed into a paper rather than a plastic bag, because plastic traps moisture and degrades biological evidence. Helping her clean up and change is the humane instinct and is the strongest competing answer, which is why it has to be talked through rather than simply refused: she decides, and the crew's job is to make sure she is deciding with the information. A genital examination is the trap: an EMT examines only what is needed to treat injury or bleeding, and the forensic examination belongs to trained clinicians. Medical care is never delayed for a police interview, and offering a provider of her preferred gender and a private, unhurried manner matters as much as anything clinical.

A 26-year-old who is about nine weeks pregnant has heavy vaginal bleeding with cramping and has passed some tissue. She is pale, with a pulse of 118 and a blood pressure of 96/60. Under most EMS protocols the EMT should:

  • a.Assume an uncomplicated miscarriage, since passing tissue accounts for the bleeding and the pain
  • b.Have her sit on the toilet during the bleeding so that any tissue can be collected cleanly
  • c.Treat her for shock, apply an external pad, and take the passed tissue to hospital
  • d.Discard the tissue she has passed, as it has no value once expelled

The pale skin, the pulse of 118 and the pressure of 96/60 make this a patient in shock, so field care is oxygen if she is hypoxic or poorly perfused, warmth, a position of comfort or supine as local protocol directs, an external pad with a count of how many are soaked so the hospital can gauge the loss, and rapid transport; the passed tissue travels with her because it helps the hospital establish what happened. Assuming a straightforward miscarriage because the passed tissue seems to explain everything is the dangerous shortcut and the strongest competitor, since a ruptured ectopic pregnancy presents in these same weeks with bleeding, cramping pain and shock, is a surgical emergency, and can shed decidual tissue that looks like a miscarriage. A patient in shock does not belong on a toilet, where she may faint and where the blood loss cannot be measured, and nothing is ever packed into the vagina.

A 14-month-old had a brief generalised seizure at home during a febrile illness. The seizure has stopped, he is sleepy but breathing well, and his frightened parents ask whether he still needs to go to hospital. The EMT should:

  • a.Reassure the parents that a febrile seizure is harmless and that no evaluation is needed
  • b.Put him in a cold bath to bring the temperature down fast
  • c.Give his fever medicine by mouth now that the seizure has stopped
  • d.Protect his airway, keep him comfortable, and transport for evaluation

A first febrile seizure needs a source for the fever to be found, so the crew supports the airway, positions him on his side, keeps the environment calm and transports, while explaining to the parents what happened, because a seizure in their child is terrifying and their calm helps him. Telling them no evaluation is needed is the tempting error, since most febrile seizures really are benign, but that is a conclusion available only after meningitis and other causes have been excluded by someone able to exclude them, and the parents keep the right to refuse once they have been told this. Cold immersion causes shivering and distress without safely lowering the temperature, and a drowsy postictal child should not be given anything by mouth.

A 9-year-old boy with autism who does not use speech is ill at home and becomes increasingly distressed as the crew works around him. The most effective approach is to:

  • a.Lower the noise and lighting and ask his mother how he communicates
  • b.Separate him from his mother so that the assessment is not influenced by her answers
  • c.Restrain him early on, because a child who does not speak will not cooperate
  • d.Speak loudly and repeat each question, since repetition helps

Reducing the sensory load, keeping the trusted caregiver present, having one person speak in short concrete phrases, explaining each touch before it happens and allowing a familiar comfort object are what actually make an assessment possible in an autistic patient, and the caregiver is the expert on this particular child's signals and pain behavior. Separating him from his mother is the strongest wrong answer, because it borrows a rule meant for a suspected-abuse interview and here removes the only person who can interpret him. Restraint escalates distress and is reserved for genuine danger to the patient or the crew, and volume and repetition add to exactly the sensory overload that is driving the behavior.

A 79-year-old with type 2 diabetes has become gradually more confused over three days. His mouth and skin are very dry, his heart rate is 116 and his blood pressure is 96/58. His breathing is of normal depth with no unusual odor, and his home meter reads 'HI'. What should the EMT most suspect?

  • a.A hyperosmolar hyperglycemic state, in which extreme dehydration develops without significant ketosis
  • b.Diabetic ketoacidosis, since a sugar too high for the home meter to read must be producing ketones and deep rapid breathing
  • c.Hypoglycemia, because confusion with a fast pulse and a low blood pressure is the classic picture of a low sugar
  • d.Dehydration from poor intake alone, with the meter reading an error

Type 2 diabetics can drift over days into a hyperosmolar hyperglycemic state: the glucose climbs very high, the osmotic diuresis strips out water, and the patient becomes profoundly dehydrated and confused, yet enough insulin remains to prevent significant ketone production, so there is no acetone odor and no deep, rapid Kussmaul breathing. Ketoacidosis is the tempting answer whenever a meter reads too high to display, which is exactly why the breathing pattern and the absent odor matter here. A hypoglycemic patient does not produce an unreadably high meter result, and simple poor intake would not explain it either. EMT care is airway, oxygen if indicated, positioning and prompt transport, because these patients need intravenous fluid.

A teenager swallowed a large number of acetaminophen (paracetamol) tablets about two hours ago. She is alert, her vital signs are normal, and she says she feels fine and does not want to go to hospital. What is the most important point for the EMT to make?

  • a.Severe liver injury can develop over the days that follow even though she feels well now
  • b.She is out of danger, because acetaminophen becomes toxic only when it is taken with alcohol or another drug
  • c.Feeling well two hours after the overdose shows the amount taken was below the toxic dose for her weight
  • d.She should be made to vomit at home and then watched by her family for the next several hours

Acetaminophen poisoning is dangerous precisely because the first hours are quiet — nausea at most, then an apparently well patient — while a toxic metabolite injures the liver over the days that follow. The antidote works best when it is started early, so assessment, blood testing and the transport decision cannot wait for symptoms to appear. Alcohol and poor nutrition increase the risk but are not required for toxicity, and inducing vomiting at home is not recommended, since it delays definitive care and risks aspiration.

An EMT is called for a 22-year-old who told a friend he wanted to end his life. He is calm and cooperative, has no injuries and answers questions politely. What is the most appropriate way to assess his risk?

  • a.Avoid raising the subject of suicide, since asking can plant the idea in a vulnerable patient's mind
  • b.Ask him directly whether he has a plan and the means to carry it out
  • c.Rely on the friend's account rather than questioning him, so that he is not made defensive
  • d.Treat his calm manner as reassuring, since a patient at genuine risk is agitated and visibly distressed

Asking plainly about suicidal thoughts, a specific plan and access to the means does not increase risk — it is how risk is assessed, and a definite plan with the means at hand marks high risk. The calm, cooperative manner is the trap in this scenario: composure can follow a decision to act, so it is not evidence of safety. A friend's account is useful but does not replace speaking with the patient himself, and the crew still keeps the scene safe and removes obvious means where it can do so safely.

During an unavoidable field delivery the baby's buttocks present first and the body delivers as far as the shoulders, but the head does not follow. Under most EMS protocols, what should the EMT do?

  • a.Support the body and slip a gloved hand in to make an airway space at the baby's face, then transport at once
  • b.Pull steadily on the baby's body with each contraction until the head delivers, keeping the traction in line with the spine
  • c.Push the baby back into the birth canal and hold it there until arrival at the hospital
  • d.Wait without touching the baby for the mother to deliver the head herself

Once a breech body has delivered and the head has not followed, the cord is compressed between the head and the pelvis and the baby's face is pressed against the vaginal wall, so most protocols have the EMT support the body, insert a gloved hand palm-toward-the-face to push the tissue away from the nose and mouth, and transport immediately while maintaining that space. Traction on the body is the intuitive response and is the one thing that must not be done, because it can trap the head further and injure the neck and spinal cord. Pushing the baby back is not an EMT procedure, and waiting passively leaves both the airway and the cord obstructed.

An 84-year-old who takes a beta blocker fell at home and has a painful, swollen thigh. He is pale and sweaty, his skin is cool, his heart rate is 74 and his blood pressure is 104/86. How should the EMT interpret that heart rate?

  • a.It rules out serious blood loss, since an injury bad enough to cause shock always drives the pulse up
  • b.It shows he is compensating well, since a normal rate in an older adult means cardiac output is being maintained
  • c.It may be blunted by his medication, so the other signs of poor perfusion carry more weight
  • d.It points to neurogenic shock from a spine injury in the fall

Beta blockers prevent the heart-rate response that normally signals blood loss, so an older patient can be bleeding significantly with a pulse in the seventies; the pale, cool, sweaty skin and the narrow pulse pressure of 104/86 are the findings that carry the weight here. Reading the normal rate as evidence of good compensation is the tempting error, and it is the one most likely to slow the transport decision. A closed femur injury can hold a large volume of blood, and nothing here suggests a cord injury, which would give warm, dry skin rather than cool and sweaty.

A 55-year-old who has taken prednisone every day for years for an autoimmune illness has had two days of vomiting and has not kept her tablets down. She is weak, with a blood pressure of 82/54, a heart rate of 122 and warm skin. What should the EMT most suspect?

  • a.An adrenal crisis brought on by stopping the steroid
  • b.Simple dehydration from the vomiting, which will settle once she can drink again at home
  • c.A vasovagal episode caused by the repeated vomiting, needing only supine positioning
  • d.A late allergic reaction to the medication she has taken for years

Long-term steroid therapy suppresses the body's own cortisol production, so a patient who cannot keep the tablets down during an illness can lose the hormone that helps maintain blood pressure and blood sugar, producing weakness, vomiting and hypotension out of proportion to the fluid loss. Dehydration is the strong competing answer and is genuinely part of the picture, but the degree of hypotension in a steroid-dependent patient who has missed doses points beyond simple fluid loss, and these patients need hospital steroid replacement rather than fluids at home. EMT care is supportive: position, oxygen if indicated, warmth, a glucose check where a meter is carried, and prompt transport.
