  1. When performing a venipuncture, which site is preferred for routine blood collection in an adult patient?

    Answer: Median cubital vein of the antecubital fossa

    The median cubital vein in the antecubital fossa is the first-choice site because it is large, well-anchored, and least painful for most patients.

  2. A collector notices that a urine specimen has a blue-green color. What does this most likely indicate?

    Answer: Possible presence of methylene blue or amitriptyline

    Blue-green urine can result from certain medications such as methylene blue, amitriptyline, or indomethacin, and should be noted in the remarks section.

  3. What is the maximum time allowed between blood collection and centrifugation for serum separator tube (SST) specimens?

    Answer: 60 minutes

    SST specimens should be centrifuged within 60 minutes of collection to prevent cellular metabolism from altering analyte concentrations.

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

    Answer: 21–22 gauge

    21–22 gauge needles are standard for routine adult venipuncture, balancing adequate flow rate with patient comfort and minimizing hemolysis.

  5. When collecting blood from a patient with an IV line in the arm, what is the best practice?

    Answer: Collect from the opposite arm or a site distal to the IV after stopping the infusion for at least 2 minutes

    Drawing from the opposite arm or below the IV site (after stopping the infusion for at least 2 minutes) prevents IV fluid contamination of the specimen.

  6. How should a capillary blood specimen be collected from a neonate's heel?

    Answer: Puncture the medial or lateral plantar surface of the heel

    CLSI guidelines specify puncturing the medial or lateral plantar surface of the heel to avoid bone and minimize risk of osteomyelitis.

  7. What does a 'rolling vein' mean and how should a collector respond?

    Answer: A vein that moves laterally when the needle approaches; anchor the vein by pulling skin taut below the puncture site

    A rolling vein moves sideways instead of staying in place; anchoring the skin below the site with the thumb stabilizes it for successful puncture.
