Which of the following is a key step to ensure proper labeling of a blood specimen?
A. Labeling after centrifugation
B. Labeling before collection
C. Labeling immediately after collection
D. Labeling once results are obtained
C
Explanation: Specimens must be labeled immediately after collection to avoid mix-ups and
ensure accurate patient identification
What is the purpose of the order of draw during blood collection?
A. To minimize patient discomfort
B. To prevent cross-contamination of additives
C. To speed up the collection process
D. To standardize needle insertion sites

B
Explanation: The order of draw minimizes the risk of additive carryover between tubes that can
interfere with test results.
How does the use of a butterfly needle benefit blood collection?
A. It reduces the risk of needlestick injury
B. It allows collection from small or fragile veins
C. It increases the collection speed
D. It eliminates the need for tourniquet use
B
Explanation: Butterfly needles provide more control and are ideal for patients with small or
fragile veins
Which storage temperature is typically recommended for blood specimens intended for
hematology analysis?
A. Room temperature
B. 2-8°C
C. −20°C
D. 37°C
A
Explanation: Hematology specimens are usually stored at room temperature to maintain cell
morphology for analysis.

During blood collection, what is the best practice to prevent contamination of the specimen?
A. Use non-sterile gloves
B. Disinfect the venipuncture site thoroughly
C. Collect in a high-traffic area
D. Delay skin antisepsis
B
Explanation: Proper skin disinfection minimizes the risk of contaminating the blood specimen
with skin flora.
What is the recommended angle for needle insertion during venipuncture?
A. 15-30 degrees
B. 45-60 degrees
C. 75-90 degrees
D. 90-100 degrees
A
Explanation: Inserting the needle at a 15-30 degree angle helps to access the vein efficiently
while minimizing tissue trauma.
How does the use of a vacutainer system benefit blood specimen collection?
A. It allows for free-flow collection
B. It ensures a closed system to reduce contamination risk
3

C. It requires no training for proper use
D. It eliminates the need for a tourniquet
B
Explanation: The vacutainer system maintains a closed environment, reducing the risk of
bacterial contamination.
Which anticoagulant is most commonly used in blood specimen collection for coagulation
studies?
A. EDTA
B. Sodium Citrate
C. Heparin
D. Lithium Heparin
B
Explanation: Sodium Citrate binds calcium ions, which are necessary for blood clotting, making
it ideal for coagulation studies.
What is the primary purpose of gently inverting a blood collection tube immediately after
specimen collection?
A. To mix the blood with additives
B. To enhance clot formation
