SECTION 1: VENIPUNCTURE PROCEDURES (25 Questions)
Q1: According to CLSI GP33-A6 standards, what are the minimum required patient identifiers
before performing venipuncture?
A. Patient's name and room number
B. Patient's full name and date of birth
C. Patient's name and medical record number
D. Patient's name and diagnosis
Correct Answer: B. [CORRECT]
Rationale: CLSI standards require two unique patient identifiers, typically full name and date of
birth, to ensure positive patient identification before specimen collection. Room numbers and
diagnoses are not acceptable identifiers.
Q2: A phlebotomist is preparing to draw blood from an adult patient. What is the maximum
recommended time a tourniquet should remain applied during venipuncture?
A. 30 seconds
B. 1 minute
C. 2 minutes
D. 3 minutes
Correct Answer: B. [CORRECT]
Rationale: The tourniquet should remain applied no longer than 1 minute to prevent
hemoconcentration, which can alter test results, particularly protein and cellular components.
Prolonged application causes stasis and hemolysis.

Q3: When performing venipuncture, at what angle should the needle be inserted relative to the
patient's skin surface?
A. 10-15 degrees
B. 15-30 degrees
C. 45-60 degrees
D. 90 degrees
Correct Answer: B. [CORRECT]
Rationale: The needle should be inserted at a 15-30 degree angle for routine venipuncture. This
angle allows proper entry into the vein lumen while minimizing the risk of through-and-through
puncture or arterial puncture.
Q4: Which of the following is the appropriate needle gauge for routine venipuncture in an adult
with normal veins?
A. 18 gauge
B. 21 gauge
C. 25 gauge
D. 27 gauge
Correct Answer: B. [CORRECT]
Rationale: A 21-gauge needle is standard for routine adult venipuncture, providing adequate
blood flow while minimizing vein trauma. Smaller gauges (25-27) are reserved for pediatric or
difficult draws; larger gauges (18) are used for blood donation or rapid transfusion.
Q5: Place the following venipuncture steps in the correct order according to CLSI standards:
A. Apply tourniquet
B. Cleanse site with 70% isopropyl alcohol
C. Positively identify patient
D. Insert needle into vein
E. Select appropriate vein
F. Release tourniquet
G. Remove needle and apply pressure
Correct Order: C, A, E, B, D, F, G. [CORRECT]
Rationale: The correct venipuncture sequence is: identify patient, apply tourniquet (≤1 min),
select vein, cleanse site (allow 30-60 seconds to dry), insert needle, release tourniquet, remove
needle, and apply pressure. This sequence ensures patient safety, vein stabilization, and proper
antiseptic action.

Q6: A patient develops petechiae around the venipuncture site immediately after tourniquet
application. What is the most likely cause?
A. Allergic reaction to the tourniquet material
B. Thrombocytopenia or bleeding disorder
C. Infection at the site
D. Improper needle angle
Correct Answer: B. [CORRECT]
Rationale: Petechiae (small hemorrhagic spots) appearing after tourniquet application indicate
capillary fragility, commonly associated with thrombocytopenia, anticoagulant therapy, or
bleeding disorders. This requires careful pressure application post-venipuncture.
Q7: During venipuncture, the phlebotomist notices the blood flow stops abruptly. What is the
most appropriate first action?
A. Immediately remove the needle and attempt a new site
B. Slightly reposition the needle or adjust the tube angle
C. Apply a new tourniquet above the current site
D. Forcefully push the tube further onto the needle
Correct Answer: B. [CORRECT]
Rationale: Blood flow cessation often indicates the needle bevel has moved against the vein
wall or the tube vacuum is exhausted. Slight repositioning or angle adjustment may restore flow
without requiring a second puncture, reducing patient trauma.
Q8: When collecting blood from a patient with difficult veins, which technique is most
appropriate?
A. Use a butterfly needle with a syringe
B. Apply the tourniquet for 3-5 minutes to dilate veins
C. Use an 18-gauge needle for faster collection
D. Perform arterial puncture instead
Correct Answer: A. [CORRECT]
Rationale: Butterfly needles (winged infusion sets) with 23-25 gauge needles are recommended
for difficult veins, pediatric patients, or hand veins. They provide better control and precision.
Prolonged tourniquet application causes hemoconcentration; arterial puncture requires additional
certification.
