5 real sample questions
After removing a winged blood-collection needle, what should the phlebotomist do with it?
A. Engage its safety feature and discard it immediately in sharps
B. Recap it with both hands before carrying it away
C. Detach the needle manually and place it in regular trash
D. Leave it on the tray until all specimens are labeled
Show answer and reasoning

Correct answer: A. Engage its safety feature and discard it immediately in sharps

  • B: Recap it with both hands before carrying it away is incorrect. Two-handed recapping creates an avoidable puncture hazard.
  • C: Detach the needle manually and place it in regular trash is incorrect. Contaminated sharps require a designated puncture-resistant container.
  • D: Leave it on the tray until all specimens are labeled is incorrect. Leaving an exposed device on the tray creates risk for staff and patients.

A disinfectant splashes onto the work surface, and the label does not provide complete cleanup instructions. What should the phlebotomist consult first?
A. The product's Safety Data Sheet
B. A patient's insurance card
C. The daily appointment schedule
D. A specimen transport manifest
Show answer and reasoning

Correct answer: A. The product's Safety Data Sheet

  • B: A patient's insurance card is incorrect. Insurance information does not describe occupational chemical controls.
  • C: The daily appointment schedule is incorrect. Scheduling data cannot identify the product's chemical hazards.
  • D: A specimen transport manifest is incorrect. A transport manifest concerns specimens rather than chemical cleanup.

A waived glucose meter displays an error code that persists after the approved troubleshooting steps. What should the phlebotomist do?
A. Estimate the result from the patient's symptoms
B. Stop testing and report the unresolved equipment problem
C. Change the result range in the procedure manual
D. Continue testing if the strips are not expired
Show answer and reasoning

Correct answer: B. Stop testing and report the unresolved equipment problem

  • A: Estimate the result from the patient's symptoms is incorrect. Symptoms cannot substitute for a valid analytical result.
  • C: Change the result range in the procedure manual is incorrect. Staff must not alter approved ranges to conceal a malfunction.
  • D: Continue testing if the strips are not expired is incorrect. In-date strips do not establish that a malfunctioning meter is reliable.

A coworker asks about a neighbor's laboratory results while standing in a public hallway. What is the best response?
A. Confirm only whether the result was abnormal
B. Show the result after hiding the patient's address
C. Discuss it quietly because the coworker is employed there
D. Decline to discuss the information in the public area
Show answer and reasoning

Correct answer: D. Decline to discuss the information in the public area

  • A: Confirm only whether the result was abnormal is incorrect. Abnormality status is still protected health information.
  • B: Show the result after hiding the patient's address is incorrect. Removing one identifier does not authorize disclosure of the result.
  • C: Discuss it quietly because the coworker is employed there is incorrect. Employment alone does not create a treatment-related need to know.

A patient asks the phlebotomist whether an elevated test result proves that the patient has diabetes. What should the phlebotomist do?
A. Interpret the value using an online reference range
B. Explain that one elevated value confirms diabetes
C. Refer the interpretation question to the licensed clinician
D. Recommend dietary treatment before the clinician reviews it
Show answer and reasoning

Correct answer: C. Refer the interpretation question to the licensed clinician

  • A: Interpret the value using an online reference range is incorrect. Reference ranges do not authorize a phlebotomist to diagnose a patient.
  • B: Explain that one elevated value confirms diabetes is incorrect. A phlebotomist cannot establish a diagnosis from an isolated result.
  • D: Recommend dietary treatment before the clinician reviews it is incorrect. Recommending treatment exceeds the phlebotomist's collection and support role.
