  1. What is the correct procedure when a vacuum tube fails to fill during venipuncture?

    Answer: Replace the tube with a new evacuated tube without withdrawing the needle

    If a vacuum tube fails to fill, it should be replaced with a new evacuated tube without removing the needle from the vein.

  2. Which needle gauge is most commonly used for routine adult venipuncture?

    Answer: 21 gauge

    A 21-gauge needle is the standard choice for routine adult venipuncture, balancing blood flow rate with patient comfort.

  3. When using a winged infusion (butterfly) set, what additional step is required when collecting a coagulation tube?

    Answer: Use a discard tube first to eliminate air from the tubing

    A discard tube must be drawn first when using a butterfly set to purge the dead-space air and ensure proper blood-to-anticoagulant ratio in the coagulation tube.

  4. How should a lancet be disposed of after a capillary puncture?

    Answer: In a sharps container immediately

    Used lancets are sharps and must be discarded immediately into an approved sharps container to prevent needlestick injuries.

  5. What does 'hemolysis' in a blood specimen most often indicate about collection technique?

    Answer: Excessive force was used drawing blood into a syringe or through a small-gauge needle

    Hemolysis commonly results from excessive aspiration force, using too small a needle gauge, or vigorous mixing, which ruptures red blood cells.

  6. Which action should be taken if a centrifuge becomes visibly unbalanced during operation?

    Answer: Turn off the centrifuge and allow it to stop on its own before opening

    An unbalanced centrifuge must be turned off and allowed to stop completely before the lid is opened to prevent injury from the spinning rotor.

  7. What is the purpose of the flange on a blood collection tube holder?

    Answer: To provide a grip surface for pushing tubes onto the needle and removing them

    The flange (wings) of the tube holder gives the phlebotomist leverage to push tubes onto the needle and to eject used tubes safely.
