Which of the following blood collection tubes does NOT require mixing after collection?
Answer: Plain red top (no additive)
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.
A patient states they are allergic to latex. Which modification is required for their blood draw?
Answer: Use of vinyl or nitrile gloves and latex-free collection supplies throughout
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.
A phlebotomist labels a specimen tube after collection but BEFORE leaving the patient's room. This practice is:
Answer: Correct—tubes must be labeled at the bedside in the patient's presence before leaving the room
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.
Which type of isolation precaution requires a phlebotomist to wear a fit-tested N95 respirator when entering the patient's room?
Answer: Airborne precautions
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.
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?
Answer: Call the ordering physician immediately to notify them and get instructions before collecting
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.
The CLSI recommended maximum time for leaving a tourniquet in place during venipuncture is:
Answer: 1 minute
CLSI guidelines specify that tourniquet application should not exceed 1 minute to prevent hemoconcentration and altered test results from prolonged venous stasis.
A phlebotomist is asked to collect a timed specimen for a 2-hour postprandial glucose. The patient was supposed to start eating at 8:00 AM. What time should the specimen be collected?
Answer: 10:00 AM exactly (2 hours after eating started)
A 2-hour postprandial glucose is collected exactly 2 hours after the start of the meal (at 10:00 AM if the meal started at 8:00 AM), not after finishing eating.
Standard precautions apply to which of the following in all patient care settings?
Answer: All blood, body fluids, non-intact skin, and mucous membranes of ALL patients regardless of diagnosis
Standard precautions apply to ALL patients without exception, treating every blood and body fluid exposure as potentially infectious, regardless of the patient's known or suspected diagnosis.
