NHA Phlebotomy Technician (CPT) — All Questions

How should an outpatient be identified before venipuncture?

• a.Ask the patient to state full name and date of birth, then match both to the requisition✓
• b.Ask, Are you Mr. Johnson, and proceed if the patient says yes
• c.Confirm the name on the sign-in sheet
• d.Match the room number and the last four digits of the record number

Two independent identifiers must be actively stated by the patient and matched against the requisition, most commonly full name and date of birth. Asking a yes-or-no question invites a confused or hard-of-hearing patient to agree incorrectly. A sign-in sheet is not a verified identifier and outpatients have no room number, which is never an acceptable identifier in any setting.CLIA

An inpatient scheduled for a type and screen has no identification wristband. What should the phlebotomist do?

• a.Ask the roommate to confirm the patient's identity
• b.Draw the specimen and note the missing band on the label
• c.Ask the nurse to verify identity and apply a new wristband before collecting✓
• d.Use the name on the door and the chart at the bedside

An inpatient must wear an attached identification band, and blood bank specimens have the strictest identification requirements because a mismatch can cause a fatal transfusion reaction. The nurse verifies identity and applies a new band before collection proceeds. Roommates, door signs and bedside charts are not verified patient identifiers and can be wrong after a room change.CLIA

A patient scheduled for a fasting lipid panel reports drinking black coffee two hours ago. What should the phlebotomist do?

• a.Notify the laboratory or provider and document the non-fasting status before collecting or rescheduling✓
• b.Send the patient home for a full 24 hour fast
• c.Draw the specimen and say nothing since coffee has no calories
• d.Collect the specimen and label it as fasting anyway

A fasting specimen typically requires 9 to 12 hours with only water, and coffee stimulates metabolism and can alter results, so the deviation must be reported and documented. Recording a non-fasting sample as fasting falsifies the record and misleads interpretation. Fasting longer than about 12 hours can itself distort results, so a 24 hour fast is not appropriate.

During a 3-hour glucose tolerance test the patient vomits 20 minutes after drinking the glucose solution. What is the correct action?

• a.Give a second glucose drink and restart the timing
• b.Shorten the test to one hour
• c.Continue the collections and note the vomiting on the last tube
• d.Notify the provider or laboratory immediately, since the test usually must be discontinued and rescheduled✓

Vomiting means the glucose load was not absorbed, so the remaining timed results are meaningless and the provider or laboratory decides whether to stop and reschedule. Repeating the drink is not the phlebotomist's decision and doubles the dose risk. Continuing the draws or arbitrarily shortening the protocol produces uninterpretable data.

A 9-year-old is brought for a blood draw by an adult neighbor with no documented authorization. What should the phlebotomist do?

• a.Verify legal authorization from a parent or guardian before collecting✓
• b.Proceed because any adult present may consent
• c.Proceed because the child agrees to the draw
• d.Ask the child to sign the consent form

A minor cannot give legal consent for a procedure, so authorization must come from a parent, legal guardian or a documented designee. A neighbor without documented authority cannot supply it, and a child's agreement is assent rather than consent. Having the child sign a form creates a record with no legal standing.

A competent adult inpatient refuses the ordered blood draw. What is the correct response?

• a.Draw anyway because a provider ordered it
• b.Tell the patient that refusing will delay discharge
• c.Have a family member hold the arm still
• d.Respect the refusal, notify the nurse or provider, and document it✓

A competent adult has the right to refuse any procedure, and proceeding without consent may constitute battery. The correct steps are to stop, explain the purpose of the test respectfully, notify the nurse or ordering provider and document the refusal. Coercing the patient or restraining an arm is never acceptable regardless of the order.

Midway through a draw an outpatient becomes pale, sweaty and says the room is spinning. What is the first action?

• a.Leave the patient to get help from the front desk
• b.Continue the draw quickly before the patient faints
• c.Hold an ammonia inhalant under the patient's nose
• d.Release the tourniquet, remove the needle, and lower the patient's head while keeping the patient seated or supine✓

Presyncope is managed by immediately stopping the draw and removing the needle so an unconscious patient is not injured, then lowering the head or laying the patient flat to restore cerebral perfusion. Continuing the collection risks a fall with the needle in place. Ammonia inhalants are discouraged because they can trigger bronchospasm, and the patient must never be left alone.

A swelling appears rapidly at the site while the tube is filling. What should the phlebotomist do?

• a.Massage the area to disperse the blood
• b.Release the tourniquet, remove the needle, and apply firm direct pressure for several minutes✓
• c.Tighten the tourniquet to slow the swelling
• d.Continue until the tube is full, then apply a bandage

Rapid swelling indicates a hematoma from blood leaking into tissue, so the draw is stopped and firm direct pressure is applied for several minutes, longer if the patient takes anticoagulants. Tightening the tourniquet increases venous pressure and worsens the leak. Continuing the draw enlarges the hematoma, and massaging spreads blood through the tissue and increases bruising.

On needle insertion the patient reports sudden shooting, electric pain radiating to the hand. What should be done?

• a.Loosen the tourniquet and continue
• b.Redirect the needle deeper to find the vein
• c.Discontinue immediately, remove the needle, and report the event✓
• d.Reassure the patient and finish the draw quickly

Shooting, electric or radiating pain and tingling suggest nerve involvement, and the needle must be removed at once to prevent lasting injury, with the event reported and documented. Continuing or redirecting the needle deepens the contact and increases the risk of permanent damage. Loosening the tourniquet does nothing about the nerve contact itself.

Small red pinpoint spots appear on the arm under the tourniquet. What do they indicate?

• a.The beginning of a hematoma
• b.Contamination of the site
• c.Petechiae, suggesting capillary fragility or a platelet problem, and a tendency to bleed at the site✓
• d.An allergic reaction to the tourniquet latex

Petechiae are tiny non-raised red spots from capillary leakage and often warn that the patient may bleed longer after the draw. They are not an allergic reaction, which appears as raised itchy welts, and not a hematoma, which is a diffuse swelling and bruise. They do not indicate contamination, but they do mean pressure should be held longer after needle removal.

During a draw the blood is bright red and pulses into the tube, filling it very quickly. What should the phlebotomist do?

• a.Continue since fast filling means a good draw
• b.Reposition the needle and collect the remaining tubes
• c.Apply a bandage without pressure and send the patient on
• d.Suspect arterial puncture, remove the needle at once, and apply firm pressure for at least five minutes✓

Bright red blood that pulsates and fills rapidly suggests an artery was entered, so the needle is withdrawn immediately and firm pressure is held at least five minutes, with the patient observed and the event reported and noted for the laboratory. Continuing or repositioning risks significant bleeding. A bandage without sustained pressure will not control arterial bleeding.

A frightened 6-year-old is scheduled for a venipuncture. Which approach is most appropriate?

• a.Tell the child that the draw will be canceled if the crying continues
• b.Show the child the needle in detail so there are no surprises
• c.Explain the steps in simple honest words, offer a comfort position with the caregiver, and work efficiently✓
• d.Promise the child that it will not hurt at all

Honest, simple explanations paired with a caregiver comfort hold reduce anxiety and improve first-attempt success, and working efficiently shortens the stressful period. Promising no pain destroys trust as soon as the needle enters. Threats increase distress, and displaying the needle usually escalates fear rather than reducing it.

Before beginning a draw, what should the phlebotomist explain to the patient?

• a.Who the phlebotomist is, that blood will be collected, and roughly what will happen✓
• b.The reference ranges the results will be compared against
• c.The likely diagnosis based on the tests ordered
• d.The cost of each test and the insurance coverage

Introducing oneself, stating that a blood specimen will be collected and briefly describing the procedure supports implied consent and reduces anxiety. Interpreting test results or offering a diagnosis is outside the phlebotomist's scope of practice. Billing questions belong to the business office, and reference ranges are part of the physician's interpretation.HIPAA

Which pair counts as two acceptable patient identifiers for a blood collection?

• a.The patient's room number and the bed letter, both of which appear on the assignment list
• b.The patient's full name and date of birth, checked against the requisition✓
• c.The patient's diagnosis and the name of the attending physician who ordered the tests
• d.The patient's initials and the last four digits of the social security number on file

An identifier must belong to the person rather than to a place or an episode of care, and it must be checked against the requisition and, for an inpatient, against the wristband. Full name with date of birth is the usual pair, and a medical record number is another. Room and bed change constantly, a diagnosis and a physician are shared by many patients, and initials are not unique.

An unconscious inpatient must be drawn and cannot state a name. How is identity established?

• a.By the name written on the whiteboard in the room, which the unit updates at every shift change
• b.By asking the patient in the next bed, who has heard staff use the name several times
• c.By checking the wristband against the requisition and having the nurse or caregiver confirm✓
• d.By the label already printed for that room in the phlebotomist's collection list for the round

The wristband is the identifier attached to the patient, so it is compared with the requisition and a nurse or other caregiver confirms. Whiteboards, printed round lists and neighbouring patients are all secondhand sources that have been wrong before. If the wristband is missing, the nurse applies a new one before the collection proceeds.

An unidentified trauma patient arrives in the emergency department and blood is needed urgently. How is the specimen identified?

• a.By the temporary identification number the facility assigns to the patient✓
• b.By a description of the patient's height, build and clothing written on the label
• c.By the ambulance run number, which the crew gives to the receiving nurse on arrival
• d.By leaving the label blank until a family member arrives and can give the name

Emergency departments assign a temporary identifier, often a number on a band with matching labels, and every specimen and every transfusion is tied to that number until identity is confirmed and the records are merged. A description is not unique, an ambulance number is not attached to the patient, and an unlabelled tube is a rejected specimen no matter how urgent the situation.

A patient asks what fasting means for the blood test scheduled tomorrow morning. What is the usual instruction?

• a.No food, and no water either, from midnight until the specimen has actually been collected
• b.No food or drink other than water for the period the laboratory specifies✓
• c.No food for four hours, which is long enough for any meal to clear the bloodstream entirely
• d.No solid food, although juice and coffee with milk are acceptable up to the appointment

Water is normally allowed and is helpful, because a dehydrated patient is harder to draw and shows hemoconcentration. The required interval belongs to the test and the laboratory, so the phlebotomist repeats what the order specifies rather than inventing a number. Juice, coffee with milk and any food raise glucose and lipids, and a four hour interval is too short for a lipid panel.

A patient scheduled for a fasting glucose admits to eating a full breakfast an hour ago. What should the phlebotomist do?

• a.Draw the specimen and say nothing, because the laboratory will detect a non-fasting sample anyway
• b.Refuse the draw and tell the patient to come back tomorrow morning without eating anything
• c.Draw the specimen and label it as fasting, since the appointment was booked as a fasting draw
• d.Notify the provider or follow the laboratory's protocol, and document the non-fasting state✓

Whether to collect now or reschedule is a clinical decision, so the phlebotomist reports the true state and follows the protocol rather than deciding alone. A glucose drawn an hour after a meal will read high, and if it is reported as fasting the patient can be labelled diabetic on the strength of a preparation error. Labelling a non-fasting specimen as fasting is a false record.

What does the basal state refer to in specimen collection?

• a.The condition of a patient who has been resting quietly in the waiting area for a quarter of an hour
• b.The condition of a patient immediately after moderate exercise, when circulation is at its best
• c.The resting condition of a patient in the early morning, about twelve hours after the last meal✓
• d.The condition of any patient whose vital signs are within the normal reference range that day

Reference intervals for many analytes were established on specimens drawn in the basal state, so a morning draw after an overnight fast and a night's rest is the condition those numbers describe. A specimen collected after exercise, a meal or a day of activity may sit outside the interval without any disease being present, which is why the collection conditions are documented.

A patient stands up from lying down and blood is drawn a few minutes later. Which change is expected?

• a.Sodium and potassium fall sharply, because standing redistributes electrolytes into the tissues
• b.Albumin and other large molecules read higher, because fluid shifts out of the vessels✓
• c.The white cell count halves, because standing pools the leukocytes in the lower limbs
• d.Nothing measurable changes, because posture affects only the blood pressure reading

Standing raises hydrostatic pressure in the legs, water leaves the circulation for the tissues, and everything too large to follow it becomes more concentrated. Albumin, total protein, calcium bound to protein, lipids and cell counts all read higher than they would lying down. The effect is real enough that some laboratories specify the posture, and it is documented when it matters.

A patient arrives for a blood draw having just run up four flights of stairs. Why does this matter?

• a.Exercise thins the blood, so every result is diluted and reads lower than the patient's true value
• b.Exertion can raise creatine kinase, lactate and potassium in the specimen✓
• c.Exercise makes the veins collapse, so a winged set must be used for the collection
• d.The patient will be too warm for the alcohol on the skin to evaporate before the puncture

Muscle activity releases creatine kinase and lactate and shifts potassium out of the cells, and vigorous exertion can move several results enough to matter, including a creatine kinase that might be read as cardiac. A short rest before the draw, when the order allows it, is the usual remedy. Exercise does not dilute blood or collapse veins, and skin preparation is unaffected.

A patient smokes a cigarette in the car park immediately before a blood draw. Which effect is documented?

• a.The white cell count and the cortisol level can both rise within minutes✓
• b.The hemoglobin falls by roughly a third within minutes of smoking a single cigarette
• c.Smoking has no measurable effect on any laboratory value unless the patient smokes daily for years
• d.The platelet count becomes unmeasurable, because nicotine causes the platelets to clump in the tube

Nicotine acutely raises white cells, cortisol and several other analytes, and long term smoking raises hemoglobin rather than lowering it because of chronic carbon monoxide exposure. Patients are asked not to smoke before a fasting or timed collection. Nothing about smoking makes a platelet count unmeasurable, and the acute effects are real even in an occasional smoker.

Why does a serum iron level need to be drawn at the time the provider specified?

• a.Because iron binds to the tube stopper if the specimen sits for more than a few hours
• b.Because the laboratory runs iron studies only once each day and the run is early
• c.Because serum iron follows a daily rhythm and is generally highest in the morning✓
• d.Because an afternoon specimen cannot be centrifuged in time to separate the serum properly

Serum iron shows diurnal variation, with morning values typically higher, so a specimen collected at a different hour cannot be compared with a morning reference interval or with the patient's own previous result. Cortisol behaves the same way. Nothing about the tube stopper, the analyser schedule or centrifugation is behind the timing instruction.

A competent adult outpatient rolls up a sleeve and holds out an arm when the phlebotomist explains the draw. What kind of consent is this?

• a.Informed consent, which is complete once the patient has been told the risks of the procedure
• b.Consent by proxy, because the provider consented on the patient's behalf when ordering the tests
• c.No consent has been given, because consent for a blood draw must always be written and signed
• d.Implied consent, shown by the patient's cooperation after the procedure was explained✓

A patient who understands what is about to happen and offers an arm has given implied consent, which is what a routine venipuncture normally proceeds on. Informed consent with a signature belongs to procedures with material risk, an ordering provider does not consent on an adult patient's behalf, and cooperation is genuine consent rather than an absence of it.

A competent adult inpatient says clearly that she does not want her blood drawn this morning. What should the phlebotomist do?

• a.Explain that the physician ordered it, so the collection has to go ahead whatever the patient prefers
• b.Stop, tell the patient the draw will not happen, and notify the nurse and document the refusal✓
• c.Return in ten minutes and try again, since patients usually change their minds once they have thought
• d.Ask a family member in the room to persuade the patient to agree before the round moves on

A competent adult may refuse any procedure, and proceeding anyway would be battery. The phlebotomist accepts the refusal without argument, tells the patient what will happen next, and reports it so the nurse or provider can discuss the consequences with her. Pressure, repeated attempts and recruiting relatives are all forms of coercion rather than consent.

A patient who speaks very little English arrives alone for a blood draw. What is the best practice?

• a.Speak more loudly and slowly in English until the patient appears to understand what is happening
• b.Ask another patient in the waiting area who speaks the same language to translate for the draw
• c.Use the facility's interpreter service, whether in person or by telephone or video✓
• d.Proceed without explanation, since the patient came in voluntarily and that is consent enough

A patient has to understand what is being done before cooperating with it, and facilities provide interpreter services precisely so that the explanation is accurate and private. Volume does not create comprehension, a stranger in the waiting room is neither qualified nor entitled to hear the patient's health information, and silence is not consent.

A phlebotomist enters an inpatient room and finds the patient asleep. What is the appropriate action?

• a.Wake the patient gently, identify yourself and confirm identity before the draw✓
• b.Draw the specimen without waking the patient, since a sleeping patient holds perfectly still
• c.Skip the patient entirely and mark the collection as refused on the round list
• d.Turn on the overhead light and begin the draw as soon as the patient stirs

A patient cannot participate in identification, consent or the report of a nerve symptom while asleep, so waking is a safety step and not merely a courtesy. It is done gently, with the phlebotomist speaking before touching. Drawing from a sleeping patient risks a sudden movement onto a needle, marking a sleeping patient as refused falsifies the record, and glaring lights are avoidable.

A phlebotomist arrives to draw an inpatient and finds the physician examining the patient. What should be done?

• a.Enter quietly and draw the blood while the physician works on the opposite side of the bed
• b.Leave, return when the examination is finished, and inform the nurse if the draw is timed✓
• c.Ask the physician to step out of the room so that the timed collection can be completed
• d.Cancel the order and let the ordering provider know that the specimen could not be obtained

The examination is not interrupted, and the phlebotomist steps out and returns. If the draw is time critical, the nurse is told so the timing can be preserved or the order rescheduled. Working around a physician at the bedside risks the patient and contaminates the field, asking a physician to leave is not the phlebotomist's call, and cancelling is premature.

An inpatient is not in the room because she has been taken to radiology. What should the phlebotomist do?

• a.Wait in the room until the patient returns, however long the imaging study happens to take
• b.Draw the patient in the next bed instead and reassign the labels once the first patient returns
• c.Report the specimen as collected and note that the patient was unavailable for the draw
• d.Notify the nurse or the laboratory, document the reason, and arrange a later collection✓

An unavailable patient is recorded as such, the reason is stated, and the collection is rescheduled with the nurse or the laboratory so the order is not simply lost. Waiting indefinitely leaves the rest of the round undrawn, drawing the wrong patient is the error the whole identification process exists to prevent, and reporting an uncollected specimen as collected is a false record.

A patient becomes pale and sweaty and loses consciousness briefly during a draw. After the needle is removed, what should the phlebotomist do?

• a.Leave the patient alone in the chair to recover privately and check on her in about ten minutes
• b.Give the patient a hot drink at once, since sugar and warmth restore consciousness fastest
• c.Stay with the patient, lower the head or lay her flat, and apply a cool damp cloth✓
• d.Help the patient stand and walk immediately, because movement restores circulation to the brain

The phlebotomist does not leave a patient who has fainted. Lowering the head or laying the patient flat restores cerebral blood flow, a cool cloth to the forehead or the back of the neck helps, and the patient rests until fully recovered before leaving, escorted if necessary. Nothing is given by mouth to someone who is not fully alert, and standing immediately invites a fall.

A patient tells the phlebotomist that the last person to draw her blood left a large bruise. What is the most useful response?

• a.Explain that bruising is unavoidable and that every patient bruises after a venipuncture
• b.Acknowledge it, examine both arms, avoid the bruised area and hold pressure longer✓
• c.Tell the patient that the previous phlebotomist must have made an error and offer an apology for it
• d.Draw from the same site so that only one area of the arm is ever affected by bruising

The useful response is clinical: look at both arms, choose a site away from any hematoma, use appropriate equipment and hold pressure until bleeding truly stops. A bruised site is avoided because drawing through it is painful and gives a poor specimen. Dismissing the concern helps no one, and blaming an absent colleague is speculation the phlebotomist cannot support.

A patient with a hearing impairment is scheduled for a blood draw. Which approach works best?

• a.Face the patient, speak clearly at a normal pace, and use writing or an interpreter✓
• b.Shout each instruction from behind the patient so the sound reaches the better-hearing ear
• c.Skip the explanation entirely, since the patient will not be able to follow it in any case
• d.Speak only to the family member who came in with the patient

Facing the patient allows lipreading and expression to help, an ordinary pace is easier to follow than exaggerated slowness, and a written note or a sign language interpreter fills any gap. Shouting distorts speech, especially from behind where the patient cannot see the speaker, and directing the conversation to a relative talks past the patient whose body it is.

How should a phlebotomist protect a patient's privacy in a shared inpatient room?

• a.Speak in a whisper about the tests so that only the patient in the next bed can hear the details
• b.Ask the neighbouring patient to leave the room until the collection has been completed
• c.Draw the curtain and keep any discussion of tests and results quiet and brief✓
• d.Say nothing at all to the patient, since silence is the only reliable way to protect information

Pulling the curtain and keeping the conversation low and to the point gives a reasonable degree of privacy in a room that offers none by design. A whisper carries surprisingly well, another patient cannot be made to leave their own room, and refusing to speak to the patient sacrifices identification and consent in the name of confidentiality.

A patient with a marked hand tremor needs an antecubital draw. Which adjustment is most helpful?

• a.Ask the patient to hold the arm perfectly still by force of will for the duration of the draw
• b.Hold the patient's wrist down firmly with the free hand throughout the whole venipuncture
• c.Draw from the hand instead, where a tremor has less effect on a small superficial vein
• d.Support the arm fully on a firm surface and use a winged set for better control✓

Resting the whole arm on an armrest or pillow removes most of the movement without anyone having to restrain the patient, and a winged set gives short, controllable tubing that tolerates small shifts. Willpower does not stop a tremor, forcibly holding a limb is both undignified and unsafe, and a moving hand is harder to work with than a supported antecubital site.

A patient becomes nauseated and says she is going to vomit during a blood draw. What is the first action?

• a.Finish the remaining tubes quickly, then hand the patient an emesis basin and step back
• b.Stop the draw, remove the needle, and give the patient an emesis basin and a cool cloth✓
• c.Tell the patient to swallow and breathe through her nose until the collection is complete
• d.Ask the patient to lean forward over the tray so the tubes are not disturbed by the movement

The needle comes out first, because vomiting moves the whole body and a needle in a vein during that movement can tear the vessel or the phlebotomist's glove. Then the patient is supported with a basin, a cool cloth and someone staying with her. Continuing the draw, coaching her to suppress it, or positioning her around the equipment all put the specimen ahead of the patient.

A ten-year-old is brought for a blood draw by a parent. How should the phlebotomist involve the child?

• a.Direct every word to the parent, since a child of that age cannot give consent in any case
• b.Tell the child nothing until the tourniquet is on, so there is no time to become frightened
• c.Explain in age-appropriate terms and give the child some choice, with the parent consenting✓
• d.Require the child to sign the same consent form that an adult patient would be asked to sign

The parent or guardian gives legal permission, but a school-age child understands a simple explanation and copes better when offered a real choice, such as which arm or whether to watch. Ignoring the child, springing the procedure on them, or asking a minor to sign an adult consent form all mistake the legal question for the human one.

A patient asks the phlebotomist to tell her the results of the blood test she had last week. What is the appropriate response?

• a.Explain that results come from her provider and offer to pass the request on✓
• b.Look the results up in the computer and read the numbers to her without any interpretation
• c.Tell her the results are confidential and cannot be released to anyone under any circumstances
• d.Say that the results looked normal, which will reassure her while she waits for the appointment

Results reach a patient through the clinician who can put them in context, and the phlebotomist redirects the request rather than reading numbers that may need explanation. The results are the patient's own information and are not withheld from her, they are simply released through the right route, and no one should be reassured about results they have not reviewed.

A patient who has been vomiting for two days arrives dehydrated for routine blood work. What should the phlebotomist expect?

• a.The veins will be unusually easy to find, because dehydration makes the vessel walls more rigid
• b.Every result will read lower than usual, because the remaining blood is thinner than normal
• c.The specimen will hemolyze automatically, so a redraw should be scheduled in advance
• d.Veins that are harder to find and results affected by hemoconcentration✓

Dehydration reduces plasma volume, so veins are less well filled and harder to enter, and the analytes left behind are more concentrated, which raises hematocrit, protein and several chemistry values. The condition of the patient is documented so the provider can interpret the results, and it makes the draw harder rather than easier.

An inpatient is wearing two identification wristbands with different medical record numbers. What should the phlebotomist do?

• a.Stop and ask the nurse to resolve it and remove the band that does not belong✓
• b.Use the band that looks newer, since the older one is clearly left over from a previous admission
• c.Use whichever band matches the requisition and draw the specimen
• d.Cut off both bands and ask the patient to state a name and date of birth instead

Two bands mean the patient may have two records, and a specimen filed under the wrong one can separate a result from the history that explains it or, in the blood bank, from a known antibody. The nurse or admitting staff sorts it out before any blood is drawn. Choosing the newer looking band or the one that happens to match is guessing, and removing identification is not a phlebotomist's decision.

A sign above an inpatient's bed reads: no venipuncture, right arm. What should the phlebotomist do?

• a.Use the right arm anyway if the left has no usable vein, and note the reason on the requisition
• b.Use the left arm, and if that is not possible ask the nurse or provider how to proceed✓
• c.Ignore the sign, since it is not part of the medical record and may be out of date
• d.Draw from the right arm below the level of the elbow, which the restriction does not cover

That sign usually reflects a mastectomy, a fistula, a graft, a cast or an affected limb after a stroke, and the restriction covers the whole arm rather than part of it. The other arm is used, and if it cannot be, the nurse or provider decides, which may mean a hand vein on the permitted side or an order to proceed anyway. A phlebotomist does not override the restriction alone.

A patient with right-sided weakness after a stroke needs a blood draw. Which arm is preferred and why?

• a.The right arm, because the weakened side has less muscle tone and the veins are easier to enter
• b.Either arm, because a stroke has no bearing on which limb may be used for a venipuncture
• c.The left arm, because circulation and sensation are better on the unaffected side✓
• d.Neither arm, because a patient after a stroke must be drawn by capillary puncture only

The unaffected side has better perfusion, normal sensation and normal muscle activity, so it heals better and the patient can report nerve pain if it occurs. An affected limb may also be edematous. The restriction is a preference rather than an absolute rule, and it is documented, but a stroke does not restrict the patient to skin puncture.

An outpatient arrives at the drawing centre with no order and says her doctor told her to come. What should happen?

• a.Draw a standard panel of common tests so the patient does not have to make a second trip
• b.Contact the ordering office to obtain the order before any specimen is collected✓
• c.Ask the patient which tests she remembers being mentioned and collect those tubes
• d.Send her away and tell her to bring a paper order signed by her doctor next time

A specimen cannot be collected without an order that says what is being tested and why, and the clinic can usually send or confirm one within minutes. Choosing tests from memory, the patient's or the phlebotomist's, produces results nobody ordered and a bill nobody expected. Turning the patient away without trying to obtain the order wastes a trip that a phone call might save.

A patient in a long term care facility is confused and has no wristband. Who may confirm the patient's identity?

• a.Another resident who has shared the dining room with the patient for several years now
• b.A staff member who knows the resident, and the identity is documented✓
• c.The name printed on the door of the room, which the facility keeps current on its records
• d.The phlebotomist's own recollection from having drawn the same resident several weeks earlier

Where no wristband is worn, a caregiver who knows the resident makes the identification and it is recorded, so there is an accountable person behind the name on the tube. A door sign is a location, another resident is not a reliable source, and a phlebotomist's memory of a face is exactly the kind of informal identification that produces a mislabelled specimen.

How should a phlebotomist begin an encounter with an outpatient in the waiting area?

• a.Call out the patient's full name and diagnosis so the right person knows to come forward
• b.Beckon the next person in the queue and start walking toward the drawing room at once
• c.Announce the tests that have been ordered so patients can sort themselves into the right rooms
• d.Call the patient by name, introduce yourself and your role, then confirm identity privately✓

A name may be called in a waiting room, but the diagnosis and the tests belong to the patient alone and are not announced. Identity is then confirmed away from other ears, using two identifiers. Introducing yourself and your role is both courteous and part of the patient's right to know who is about to perform a procedure on them.

A patient who is visually impaired arrives for a blood draw. Which practice is most appropriate?

• a.Take the patient's arm and steer her to the chair without speaking, which is quicker for both
• b.Have a family member carry out the identification so the patient does not have to be asked
• c.Say who you are, describe each step before it happens, and offer your arm to guide her✓
• d.Hand the patient a printed information sheet describing the procedure she is about to undergo

Describing what is about to happen replaces the visual cues the patient cannot use, and offering an arm to hold lets her stay in control of her own movement rather than being steered. She confirms her own identity as any other competent adult does, and a printed sheet is of no use to someone who cannot read it.

A patient becomes agitated and swings an arm as the phlebotomist prepares the site. What is the correct response?

• a.Have a colleague hold both of the patient's arms down so the collection can be completed
• b.Stop, step back out of range, and get help before deciding whether to continue✓
• c.Speak sharply to the patient so the behaviour stops and the draw can go ahead as planned
• d.Continue quickly with a shorter needle, which reduces the injury risk if the arm moves

Personal safety comes first, and a moving arm plus a needle is how both the patient and the phlebotomist get hurt. The phlebotomist withdraws to a safe distance, calls for assistance and lets the nursing staff assess what is driving the behaviour, which may be pain, delirium or low blood sugar. Restraint is a clinical decision made by others, and no needle length makes the situation safe.

A patient tells the phlebotomist she drank several glasses of wine last night before a fasting liver panel this morning. What should the phlebotomist do?

• a.Draw the specimen and report what the patient said, so the result can be read in context✓
• b.Cancel the collection, because alcohol within twelve hours invalidates every liver test
• c.Draw the specimen and say nothing, since alcohol has no effect on any liver measurement
• d.Advise the patient that her results will certainly be abnormal and that she should stop drinking

Recent alcohol can move several results, so the information is passed on rather than acted on alone, and the provider decides whether it changes the interpretation or whether the test should be repeated. Cancelling on the phlebotomist's own judgement removes a clinical decision from the clinician, and predicting an abnormal result or giving lifestyle advice is outside the role.

A patient asks to see the requisition before agreeing to the draw. How should the phlebotomist respond?

• a.Refuse, because a requisition is an internal laboratory document and not the patient's property
• b.Refuse politely and offer to describe the tests verbally, which is easier for a patient to follow
• c.Show it, since the information on it is the patient's own✓
• d.Show it only after the specimen has been collected and the tubes have all been labelled

The requisition holds the patient's name, the ordering provider and the tests requested, all of which are her own health information, and there is no reason to withhold it. Letting her read it supports informed cooperation. Deferring until after the draw defeats the purpose of asking, and treating her own information as an internal document is a common but mistaken habit.

A patient's culture makes her uncomfortable being touched by a phlebotomist of the opposite sex. How should this be handled?

• a.Explain that staffing does not permit preferences and complete the draw as assigned
• b.Try to accommodate the request where staffing allows, and document what was done✓
• c.Refuse the request, since accommodating it would be unfair to the other patients waiting
• d.Ask the patient to justify the request before deciding whether it can be accommodated

Where another phlebotomist is available, honouring the preference costs little and preserves the patient's dignity and her willingness to come back. Where it is not possible, the situation is explained and options such as a chaperone are offered. Demanding a justification for a personal or religious preference is intrusive, and dismissing it invites a refusal of care.

A colleague asks the phlebotomist to look up a neighbour's laboratory results in the hospital system out of curiosity. What is the correct response?

• a.Look them up but do not print or write anything down, which leaves no trace of the access
• b.Look them up only if the neighbour is a patient of the same department that both staff work in
• c.Look them up and share only whether the results were normal, without giving any actual numbers
• d.Decline; access is limited to what your own job requires and every look-up is logged✓

Access to a record is permitted only for a work purpose that concerns that patient, and curiosity is never one. Audit trails record every view, and staff are dismissed and fined for exactly this. Reading without printing still counts as access, working in the same department does not create a treatment relationship, and reporting a result as normal is still a disclosure.

A patient in a hospice unit is ordered a routine chemistry panel and tells the phlebotomist he does not want any more tests. What should the phlebotomist do?

• a.Explain that the panel is routine and complete the collection
• b.Accept the refusal, notify the nurse so the order can be reviewed, and document it✓
• c.Draw the specimen because a hospice patient's goals of care do not affect laboratory orders
• d.Ask the family whether they would like the specimen collected despite what the patient said

A competent patient's refusal stands wherever he is, and in a comfort focused setting it is also a signal that an order may no longer match the goals of care. Reporting it lets the team review the order rather than repeat the conversation tomorrow. Persuading the patient, drawing anyway or asking the family to overrule him all disregard his stated wish.

A patient who is a nurse asks the phlebotomist to use a butterfly needle because that is what always works on her. What should the phlebotomist do?

• a.Explain that equipment selection is the phlebotomist's decision and use the usual straight needle
• b.Use the butterfly for every future patient, since a nurse's advice reflects clinical experience
• c.Consider the request along with what the veins show, and use a winged set if it is suitable✓
• d.Ask her to sign a statement accepting responsibility for the equipment she has requested

A patient who has been drawn many times often knows what works, and that history is useful information rather than an instruction to be resisted. The phlebotomist still palpates and chooses equipment that fits the vein and the tubes ordered. Generalising one patient's preference to everyone is not evidence, and asking for a signed waiver over a needle choice is disproportionate.

Why is it important to tell a patient roughly how many tubes will be drawn before starting?

• a.It prepares the patient for the time it takes and reduces alarm when tubes keep changing✓
• b.It is a legal requirement that a written tube count be given to every outpatient beforehand
• c.It allows the patient to choose which of the ordered tests she is willing to have collected
• d.It lets the patient decide how long the tourniquet stays on

Patients who are not told often assume something has gone wrong when a fourth or fifth tube appears, and a brief warning prevents that alarm and the movement that can come with it. It is good practice rather than a legal requirement. Choosing among ordered tests is a conversation for the provider, and tourniquet time is set by the standard, not by preference.

A patient says she feels fine but has fainted at every previous blood draw. What is the most sensible precaution?

• a.Draw her standing, so that she has less distance to fall if she does lose consciousness
• b.Draw her reclined or in a chair with a locking arm, and stay with her afterwards✓
• c.Give her a sugary drink first, because low blood sugar is what causes fainting at a blood draw
• d.Complete the draw as fast as possible, since a short procedure cannot trigger a faint

A history of syncope is the strongest predictor of the next one, so the position is chosen for what happens if she faints rather than for whether she feels fine now. Reclining prevents a fall, and staying with her afterwards catches a delayed episode. Vasovagal fainting is not caused by low blood sugar, and speed does not prevent it.

Which statement about drawing blood from a minor is generally correct in the United States?

• a.A minor of any age may consent to a blood draw as long as they arrive at the clinic alone
• b.A minor may never be drawn without a parent physically present in the room at the time
• c.A parent or legal guardian normally gives permission, with exceptions set by state law✓
• d.The phlebotomist decides whether a minor is mature enough to give permission for the draw

Permission for a minor normally comes from a parent or legal guardian, but every state carves out exceptions, commonly for emancipated minors and for care such as sexually transmitted infection testing, so the facility's policy and state law govern. A parent's physical presence is not always required, and maturity is not a judgement a phlebotomist makes at the chair.

How should a phlebotomist document a patient's refusal of an ordered blood draw?

• a.Write refused on the requisition and leave it at the nursing station without saying anything
• b.Record who refused, the date and time, what was said, and who was notified✓
• c.Record only that the specimen was not obtained, since the reason is confidential to the patient
• d.Ask the patient to write and sign a statement explaining why she declined the collection

A refusal is a clinical event, so the note says who declined, when, in the patient's own words where possible, and which nurse or provider was told. That record is what protects both the patient and the phlebotomist when the missing result is questioned. A single word on a form conveys none of it, and no patient is required to write a justification.

A patient is scheduled for a fasting draw and asks whether she may take her morning blood pressure tablet with water. What is the correct answer?

• a.No medication may be taken during a fast, because any tablet will invalidate the results
• b.Refer the question to her provider or the laboratory, and do not advise stopping a medication✓
• c.Yes, all oral medications are safe during a fast and none of them affect any blood test
• d.Yes, but only if she waits until after the specimen has been collected to swallow the tablet

Whether a medication may be delayed is a clinical judgement, and telling a patient to skip an antihypertensive is outside a phlebotomist's role and can cause real harm. The question goes to the prescriber or the laboratory, whose test directory often states it. A blanket yes and a blanket no are both wrong because it depends on the drug and the test.

Why should a phlebotomist ask a patient about previous reactions before starting a draw?

• a.So the results can be compared with the patient's reaction at the previous appointment
• b.So the phlebotomist can decide whether the patient is exaggerating the difficulty of the draw
• c.So the laboratory can add a comment about the patient's anxiety to the printed report
• d.So syncope, latex allergy and a difficult access history can be planned for in advance✓

Asking turns a surprise into a plan: a fainter is reclined, a latex allergy changes every item that touches the skin, and a history of difficult access changes the equipment and who performs the draw. None of it concerns the results themselves, and none of it is a judgement about whether the patient is exaggerating.
