Q1 Question 1 of 100
A 45-year-old patient presents for routine venipuncture at an outpatient clinic. The
phlebotomist prepares to collect multiple tubes using the evacuated tube system (ETS). What
is the correct order of draw for this patient when no blood culture is required?
A. Light blue, red/gold, green, lavender, gray
B. Red/gold, light blue, lavender, green, gray
C. Lavender, light blue, red/gold, green, gray
D. Gray, red/gold, light blue, green, lavender
Correct Answer: A
Rationale:
The CLSI order of draw is blood cultures (yellow), coagulation (light blue), serum (red/gold/tiger), heparin (green),
EDTA (lavender), and fluoride (gray). Drawing light blue before serum tubes prevents tissue factor contamination from
affecting coagulation results. Choice B is wrong because serum tubes must follow the light blue tube to avoid additive
carryover altering clotting times.
Q2 Question 2 of 100
A 67-year-old chemotherapy patient needs blood work, but the antecubital veins are
sclerosed and fragile. Which collection device is most appropriate for this patient?
A. 21-gauge evacuated tube needle for fast flow
B. 23-gauge butterfly winged infusion set
C. 18-gauge syringe needle for difficult draws
D. Spring-loaded lancet for capillary puncture
Correct Answer: B
Rationale:
A 23-gauge butterfly (winged infusion) set is ideal for sclerosed, fragile, or small veins common in chemotherapy and
geriatric patients. The flexible wings and short tubing allow precise control while reducing vein trauma and hemolysis
risk. Choice A risks further vein damage in compromised vessels; Choice D cannot provide adequate volume for
routine chemistry and hematology panels.

, Q3 Question 3 of 100
A phlebotomist is performing a capillary puncture on a 4-year-old child for a complete blood
count. After warming the middle finger and cleansing with alcohol, what is the next correct
step?
A. Puncture the central fleshy pad of the fingertip immediately
B. Apply pressure with a gauze pad before puncturing
C. Allow the alcohol to air dry completely before puncturing
D. Puncture perpendicular to the fingernail edge
Correct Answer: C
Rationale:
Alcohol must air-dry completely before puncture to ensure adequate antisepsis and to prevent hemolysis and dilution
of the specimen. Puncturing through wet alcohol introduces alcohol into the drop, producing falsely abnormal cell
morphology and chemistry values. Choice A is wrong because the central pad is more sensitive; the lateral side of the
fingertip is the recommended puncture site.
Q4 Question 4 of 100
A 3-day-old neonate requires a heelstick for phenylketonuria screening. The phlebotomist
selects a proper sterile lancet (no deeper than 2.0 mm). Which area of the heel is the
approved puncture site?
A. Central posterior curve of the heel pad
B. Medial arch of the foot near the heel
C. Posterior heel curve behind the ankle
D. Lateral plantar surface of the heel
Correct Answer: D
Rationale:
The lateral plantar surface is the only approved heelstick site because it avoids the calcaneus bone, reducing the risk
of osteochondritis. The accepted zone is bounded medially by a line from the great toe to the heel and laterally by a
line from between the fourth and fifth toes to the heel. Choice A (central pad) overlies the calcaneus and is
contraindicated.

, Q5 Question 5 of 100
A 52-year-old patient is scheduled for a comprehensive metabolic panel. After applying the
tourniquet, the phlebotomist has difficulty locating a vein and palpates for over a minute.
What is the maximum recommended tourniquet dwell time?
A. 1 minute
B. 2 minutes
C. 3 minutes
D. 5 minutes
Correct Answer: A
Rationale:
The CLSI standard limits tourniquet application to one minute to prevent hemoconcentration, which falsely elevates
protein-bound calcium, potassium, and hemoglobin. Prolonged tourniquet time also causes patient discomfort and
increased bruising risk. If vein location exceeds one minute, the tourniquet should be released and reapplied after a
brief rest period.
Q6 Question 6 of 100
A phlebotomist is selecting a needle for routine venipuncture on a healthy adult with palpable
antecubital veins. Which gauge is most commonly used for this procedure?
A. 17-gauge for maximum blood flow
B. 21-gauge for standard adult draws
C. 25-gauge for fragile veins
D. 14-gauge for blood donation
Correct Answer: B
Rationale:
The 21-gauge needle is the standard for routine adult venipuncture because it balances flow rate with patient comfort
and minimizes hemolysis. Choice A is unnecessarily large and increases patient discomfort; Choice D is reserved for
blood donation collection. Smaller gauges like 25 are typically used only for butterfly sets in difficult draws.
