correct answer and EXPERT RATIONALE — this active recall method maximizes
retention and prepares you for real exam conditions.
SECTION 1: VENIPUNCTURE TECHNIQUES
1. What is the recommended angle for needle insertion during a routine
venipuncture?
A. 5–10 degrees
B. 20–25 degrees
C. 15–30 degrees
D. 35–45 degrees
E. 45–60 degrees
, Correct Answer: C. 15–30 degrees EXPERT RATIONALE: The standard angle
for venipuncture needle insertion is 15–30 degrees, bevel up. This range allows
smooth entry into the vein without passing through the posterior wall, minimizing
hematoma risk and patient discomfort.
2. Which vein is most commonly used for routine venipuncture?
A. Cephalic vein
B. Basilic vein
C. Dorsal metacarpal vein
D. Median cubital vein
E. Femoral vein
Correct Answer: D. Median cubital vein EXPERT RATIONALE: The median
cubital vein is the first choice for venipuncture because it is large, well-anchored,
close to the surface, and generally less painful to access. It lies in the antecubital
fossa and is the most accessible vein in most patients.
3. What does "bevel up" mean during venipuncture?
A. The needle is inserted at a downward angle
B. The syringe plunger is pulled back before insertion
C. The opening of the needle faces upward toward the ceiling
D. The needle is rotated 180 degrees after entry
E. The tourniquet is applied above the bevel
Correct Answer: C. The opening of the needle faces upward toward the ceiling
EXPERT RATIONALE: "Bevel up" means the slanted opening (bevel) of the
needle tip faces upward. This orientation allows the needle to penetrate the skin
and vein wall smoothly, reduces trauma, and ensures proper blood flow into the
collection tube.
,4. How long should a tourniquet remain applied before venipuncture is
performed?
A. Up to 5 minutes
B. Up to 4 minutes
C. No more than 3 minutes
D. No more than 1 minute
E. Exactly 2 minutes
Correct Answer: D. No more than 1 minute EXPERT RATIONALE: A
tourniquet should not remain in place for more than 1 minute before blood
collection begins. Prolonged tourniquet application causes hemoconcentration and
hemostasis, leading to falsely elevated results for certain analytes including
potassium and proteins.
5. What is the primary purpose of applying a tourniquet during venipuncture?
A. To sterilize the puncture site
B. To prevent bruising
C. To hold the needle steady
D. To distend veins and make them more accessible
E. To reduce patient anxiety
Correct Answer: D. To distend veins and make them more accessible
EXPERT RATIONALE: The tourniquet applies pressure that slows venous blood
return to the heart, causing veins to distend (enlarge) and become more visible and
palpable. This makes vein selection and needle insertion easier.
6. Where should a tourniquet be placed when performing antecubital
venipuncture?
, A. Below the wrist
B. Directly over the antecubital fossa
C. On the forearm 2 cm below the elbow
D. 3–4 inches above the venipuncture site
E. At the shoulder joint
Correct Answer: D. 3–4 inches above the venipuncture site EXPERT
RATIONALE: The tourniquet should be placed 3–4 inches (approximately 7–10 cm)
above the intended venipuncture site. This placement provides adequate venous
distension without interfering with needle placement or being too close to the site.
7. Which needle gauge is most commonly used for routine adult
venipuncture?
A. 16 gauge
B. 18 gauge
C. 21 gauge
D. 23 gauge
E. 25 gauge
Correct Answer: C. 21 gauge EXPERT RATIONALE: The 21-gauge needle is
the standard for routine adult venipuncture. It is large enough to allow adequate
blood flow without causing hemolysis, yet small enough to minimize patient
discomfort and vein damage.
8. What happens to needle gauge size as the gauge number increases?
A. The needle becomes longer
B. The needle becomes shorter
C. The needle becomes wider
