Question 1

Which of the following blood collection tubes does NOT require mixing after collection?

Accepted Answer

Plain red top (no additive)

Answer

Plain red-top tubes contain no additives; blood is allowed to clot naturally without mixing. All other tubes with additives require gentle inversion to mix the additive with blood.

Question 2

A patient states they are allergic to latex. Which modification is required for their blood draw?

Accepted Answer

Use of vinyl or nitrile gloves and latex-free collection supplies throughout

Answer

A latex allergy requires latex-free gloves (nitrile or vinyl) and latex-free supplies (tourniquet, tape) to prevent potentially life-threatening allergic reactions including anaphylaxis.

Question 3

A phlebotomist labels a specimen tube after collection but BEFORE leaving the patient's room. This practice is:

Accepted Answer

Correct—tubes must be labeled at the bedside in the patient's presence before leaving the room

Answer

CLSI GP47 requires that all specimens be labeled at the bedside in the patient's presence immediately after collection—this is a non-negotiable patient safety standard.

Question 4

Which type of isolation precaution requires a phlebotomist to wear a fit-tested N95 respirator when entering the patient's room?

Accepted Answer

Airborne precautions

Answer

Airborne precautions (for diseases like TB, measles, chickenpox) require a fit-tested N95 or higher respirator because the pathogens are transmitted via tiny airborne particles that remain suspended.

Question 5

A blood specimen for a fasting lipid panel is collected at 10:30 AM. The patient says they ate breakfast at 7:00 AM. What should the phlebotomist do?

Accepted Answer

Call the ordering physician immediately to notify them and get instructions before collecting

Answer

When a patient is not appropriately fasted for a test requiring fasting, the ordering physician should be notified to determine whether to collect now (non-fasting) with notation or reschedule.
