样题与解析
以下是本题库中的部分真题与完整解析。完整题库请用上方的刷题工具。
- 1. Airway & Ventilation
What is the normal resting respiratory rate for a healthy adult?
- a.12 to 20 breaths per minute
- b.20 to 30 breaths per minute
- c.6 to 10 breaths per minute
- d.30 to 40 breaths per minute
答案: a
解析: A healthy adult at rest breathes about 12 to 20 times per minute. Rates persistently above or below this range suggest respiratory distress and warrant closer assessment and possible ventilatory support.
- 2. Airway & Ventilation
Which patient is the best candidate for a nasopharyngeal airway?
- a.A patient with suspected skull base fracture and clear fluid from the nose
- b.A fully alert patient with no distress
- c.A semiconscious patient with an intact gag reflex who needs airway support
- d.A patient in cardiac arrest with severe facial trauma
答案: c
解析: A nasopharyngeal airway is tolerated by patients with an intact gag reflex, making it useful for semiconscious patients. It is avoided with suspected basilar skull fracture because of the risk of intracranial misplacement.
- 3. Cardiology & Resuscitation
What is the recommended compression rate for adult CPR?
- a.100 to 120 per minute
- b.60 to 80 per minute
- c.140 to 160 per minute
- d.80 to 100 per minute
答案: a
解析: High-quality CPR uses a compression rate of 100 to 120 per minute. Rates that are too slow or too fast reduce cardiac output and coronary perfusion.
- 4. Cardiology & Resuscitation
If a patient in cardiac arrest has a transdermal medication patch on the chest where an AED pad must go, you should:
- a.Place the pad directly over the patch
- b.Cancel AED use
- c.Remove the patch and wipe the area before applying the pad
- d.Apply the AED pad to the back only
答案: c
解析: A medication patch under an AED pad can block energy delivery or cause a burn. Remove it and wipe the skin dry before placing the pad.
- 5. Cardiology & Resuscitation
After an AED delivers a shock, the rescuer should:
- a.Immediately resume chest compressions
- b.Check for a pulse for 30 seconds
- c.Wait for the AED to advise again before touching the patient
- d.Remove the pads
答案: a
解析: Immediately after a shock, resume CPR starting with compressions for about two minutes before the next rhythm analysis. This minimizes the pause in blood flow and improves outcomes.
- 6. Trauma
The most appropriate position for a hypotensive trauma patient in shock (without spinal injury) is generally:
- a.Supine to maintain perfusion, keeping the patient warm
- b.Sitting fully upright
- c.Prone
- d.Standing to improve circulation
答案: a
解析: A patient in shock is usually kept supine to support perfusion of vital organs, along with oxygen and warmth. Preventing heat loss helps limit worsening of shock.
- 7. Medical, OB/GYN
For a patient having a severe allergic reaction (anaphylaxis) with prescribed medication available, the EMT may assist with:
- a.Oral glucose
- b.Activated charcoal
- c.An epinephrine auto-injector
- d.Aspirin
答案: c
解析: Anaphylaxis is treated with epinephrine, and EMTs may assist a patient with their prescribed auto-injector. Epinephrine reverses airway swelling and low blood pressure caused by the reaction.
- 8. Medical, OB/GYN
During normal childbirth, once the infant's head delivers, the EMT should:
- a.Support the head and check whether the cord is around the neck
- b.Pull firmly on the head to speed delivery
- c.Push the head back to delay birth
- d.Place the mother prone
答案: a
解析: 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.
- 9. Medical, OB/GYN
A patient with a possible opioid overdose has slow, shallow breathing. The EMT's first priority is to:
- a.Give oral glucose
- b.Give aspirin
- c.Support ventilation and oxygenation with a bag-valve mask
- d.Encourage the patient to walk it off
答案: c
解析: The immediate life threat in opioid overdose is respiratory depression, so support ventilation with a BVM and oxygen. Naloxone may be administered per protocol, but airway and breathing come first.
- 10. EMS Operations
A competent adult refuses care after being informed of the risks. The EMT should:
- a.Respect the refusal, document it thoroughly, and encourage the patient to call back if needed
- b.Force treatment anyway
- c.Leave without any documentation
- d.Have the patient sign nothing and depart quietly
答案: a
解析: A competent, informed adult has the right to refuse care, and the refusal must be clearly documented after explaining the risks. Encourage the patient to seek help if symptoms worsen and involve medical direction as appropriate.
