Which of the following describes the correct order of draw when using evacuated tubes?
Answer: Light blue, red/SST, green, lavender, gray
CLSI order of draw is: blood cultures, light blue (citrate), red/SST, green (heparin), lavender (EDTA), gray (fluoride/oxalate) to prevent cross-contamination between additives.
What is the proper disposal method for used phlebotomy needles?
Answer: Immediately placing in an approved sharps container without recapping
Used needles must be discarded immediately in an approved puncture-resistant sharps container without recapping to prevent needlestick injuries.
A patient reports feeling faint and lightheaded during a blood draw. What is the phlebotomist's first action?
Answer: Remove the needle, apply pressure, and have the patient lower their head or lie down
Removing the needle and positioning the patient safely (reclined or head between knees) is the immediate priority to prevent injury from fainting.
What is the maximum recommended time between specimen collection and centrifugation for most chemistry tests?
Answer: 2 hours
Most specimens should be centrifuged within 2 hours of collection to prevent cellular metabolism from altering analyte concentrations.
Which test requires a specimen to be transported on ice immediately after collection?
Answer: Ammonia level
Ammonia is highly unstable and must be transported on ice to slow red blood cell metabolism that continuously produces ammonia after collection.
What is the role of the serum separator gel in an SST tube?
Answer: It forms a physical barrier between serum and clot after centrifugation
The gel is thixotropic and changes viscosity during centrifugation, migrating between the clot and serum to form a stable physical barrier for specimen integrity.
Which organization certifies phlebotomists at the national level in the United States and awards the CPT credential?
Answer: National Healthcareer Association (NHA)
The National Healthcareer Association (NHA) administers the Certified Phlebotomy Technician (CPT) exam, one of the primary national certification credentials for phlebotomists.
