Question 1:
When performing a capillary blood collection, why is the first drop of blood wiped
away?
A. It contains clotting factors
B. It has higher tissue fluid contamination
C. It improves specimen volume
D. It prevents hemolysis
Correct Answer: B. It has higher tissue fluid contamination
Rationale:
The first drop of blood from a capillary puncture is typically contaminated with
interstitial (tissue) fluid, which can dilute the specimen and alter test results.
Removing this drop improves accuracy. The other options are incorrect because
clotting factors are not the primary concern, and wiping does not increase volume or
prevent hemolysis directly.
Question 2:
Blood applied in circles on filter paper is used for which test?
A. Blood culture
B. PKU screening
C. Coagulation profile
D. Glucose tolerance test
Correct Answer: B. PKU screening
Rationale:
Phenylketonuria (PKU) testing uses dried blood spots on special filter paper for
metabolic screening. Other tests require liquid blood samples and cannot use dried
specimens.
Question 3:
,2026/2027
Complete clotting of a blood specimen at room temperature typically takes:
A. 10 minutes
B. 20 minutes
C. 30 minutes
D. 60 minutes
Correct Answer: C. 30 minutes
Rationale:
Blood usually requires about 30 minutes to fully clot at room temperature before
serum separation. Shorter times may result in incomplete clotting and inaccurate
results.
Question 4:
Petechiae observed after tourniquet application most likely indicates:
A. Normal capillary response
B. Excessive bleeding tendency
C. Infection
D. Dehydration
Correct Answer: B. Excessive bleeding tendency
Rationale:
Petechiae suggest fragile capillaries or clotting disorders, indicating a risk of
excessive bleeding. This finding requires caution during venipuncture.
Question 5:
Which device helps visualize veins during venipuncture?
A. Otoscope
B. Venoscope
C. Microscope
D. Doppler
Correct Answer: B. Venoscope
Rationale:
A venoscope uses light to enhance vein visibility, especially in difficult venous access
patients.
Question 6:
,2026/2027
The tourniquet should be placed approximately:
A. 1 inch above site
B. 2 inches above site
C. 3–4 inches above site
D. 6 inches above site
Correct Answer: C. 3–4 inches above site
Rationale:
Proper placement ensures venous engorgement without affecting arterial flow or
specimen integrity.
Question 7:
Which tube is most commonly used for coagulation studies?
A. Red top
B. Green top
C. Lavender top
D. Light blue top
Correct Answer: D. Light blue top
Rationale:
Light blue tubes contain sodium citrate, which preserves coagulation factors for
accurate testing.
Question 8:
After filling the last blood collection tube, the next step is to:
A. Remove tourniquet
B. Remove tube from holder
C. Mix the tube vigorously
D. Apply bandage immediately
Correct Answer: B. Remove tube from holder
Rationale:
The tube is safely removed before needle withdrawal and site care procedures.
Question 9:
A 20° needle insertion angle is:
, 2026/2027
A. Correct for venipuncture
B. Too shallow
C. Too steep
D. Used for capillary puncture
Correct Answer: B. Too shallow
Rationale:
Standard venipuncture requires a 15–30° angle, but 30° is more appropriate for proper
vein entry.
Question 10:
If blood is not obtained during venipuncture, the phlebotomist should:
A. Remove needle immediately
B. Force deeper insertion
C. Slightly adjust needle position
D. Switch arm
Correct Answer: C. Slightly adjust needle position
Rationale:
Gentle repositioning may correct vein entry without causing trauma.
Question 11:
The most critical analyte affected by hemolysis is:
A. Sodium
B. Chloride
C. Potassium
D. Glucose
Correct Answer: C. Potassium
Rationale:
Red blood cells contain high potassium levels, which are released during hemolysis,
falsely elevating results.
Question 12:
The primary purpose of a syringe transfer device is to:
A. Increase blood flow
B. Prevent clotting
