1. What is the term for the clear, straw-colored liquid portion of blood
that remains after clotting has occurred?
a. Plasma
b. Serum
c. Hematocrit
d. Buffy coat
Correct Answer: b. Serum
Rationale: Serum is the liquid portion of blood that remains after a clot
has formed, while plasma is the liquid portion of anticoagulated blood.
Hematocrit is the percentage of red blood cells, and the buffy coat
contains white blood cells and platelets.
2. A phlebotomist is preparing to perform a venipuncture using an
evacuated tube system. After applying the tourniquet and cleansing
the site, what is the NEXT step?
a. Anchor the vein below the puncture site
b. Uncap and inspect the needle
c. Explain the procedure to the patient
d. Ensure the sharps container is nearby
,Correct Answer: a. Anchor the vein below the puncture site
Rationale: After site preparation, the phlebotomist must anchor the
vein to prevent it from rolling during needle insertion. The needle
should be uncapped and inspected before site cleaning, and procedure
explanation occurs before site preparation.
3. Which of the following additives is used in a Pink Top Tube for blood
banking purposes?
a. Sodium polyanethole sulfonate (SPS)
b. Sodium heparin
c. Potassium EDTA
d. Acid citrate dextrose (ACD)
Correct Answer: c. Potassium EDTA
Rationale: Pink top tubes contain potassium EDTA and are used
primarily in blood banking for compatibility testing and cross-matching.
SPS is found in yellow top blood culture tubes, sodium heparin in green
top tubes, and ACD in yellow top tubes for DNA studies.
4. A phlebotomist with a known latex allergy should take which of the
following actions?
a. Wear latex gloves but limit wear time to less than 5 minutes
b. Wear nitrile gloves instead
c. Wear latex gloves inside-out
d. Perform the procedure without gloves and wash hands thoroughly
Correct Answer: b. Wear nitrile gloves
Rationale: Nitrile gloves are an appropriate alternative for individuals
with latex allergies. Wearing latex gloves (even for short periods or
inside-out) does not eliminate the allergen exposure risk. Gloves must
always be worn for venipuncture procedures.
,5. A patient refuses a venipuncture procedure both verbally and
physically. What should the phlebotomist do?
a. Inform the patient they will still be billed
b. Re-explain the procedure in case of misunderstanding
c. Inform the patient they must reschedule
d. Immediately report the refusal and actions taken to their supervisor
Correct Answer: d. Immediately report the refusal and actions taken
to their supervisor
Rationale: When a patient refuses a procedure, the phlebotomist must
report the refusal to their supervisor immediately. Patients have the
right to refuse treatment at any time, and the refusal must be
documented appropriately.
6. Which federal regulation ensures that a phlebotomist is qualified to
perform their job duties?
a. OSHA
b. HIPAA
c. ICD-10 Codes
d. CLIA
Correct Answer: d. CLIA
Rationale: The Clinical Laboratory Improvement Amendments (CLIA)
establish quality standards for laboratory testing and ensure that
personnel are qualified to perform their duties. OSHA addresses
workplace safety, HIPAA protects patient privacy, and ICD-10 codes are
for diagnosis classification.
7. Which of the following MUST be present on a laboratory requisition
form before a phlebotomist can proceed with blood collection?
a. Patient's organ donor status
b. A specimen identification code
, c. Laboratory's CLIA number
d. Patient's emergency contact
Correct Answer: b. A specimen identification code
Rationale: A specimen identification code (or unique patient identifier)
is required on requisition forms to ensure proper specimen tracking and
prevent errors. Organ donor status, CLIA numbers, and emergency
contacts are not mandatory for specimen collection.
8. A patient seems hesitant and confused after the phlebotomist
explains the venipuncture procedure. How should the phlebotomist
respond?
a. Assume the patient has heard enough and proceed
b. Leave the room to get another healthcare provider
c. Repeat the same explanation more slowly
d. Rephrase the explanation and invite clarifying questions
Correct Answer: d. Rephrase the explanation and invite clarifying
questions
Rationale: When a patient is confused, the phlebotomist should
rephrase the explanation in simpler terms and encourage questions to
ensure informed consent. Effective communication includes adapting to
the patient's understanding level.
9. What is the recommended maximum total volume of blood that
should be drawn from a patient within a 24-hour period?
a. 0.05% - 1% of total blood volume
b. 1% - 5% of total blood volume
c. 5% - 10% of total blood volume
d. 10% - 15% of total blood volume
Correct Answer: b. 1% - 5% of total blood volume
Rationale: The standard recommendation for blood draws within a 24-
