QUESTION 1
During a capillary blood collection, the first drop of blood is wiped away primarily
because:
A. It contains anticoagulant contamination
B. It has a higher concentration of tissue fluid
C. It prevents platelet activation
D. It reduces hemolysis risk
Correct Answer: B. It has a higher concentration of tissue fluid
Rationale:
The first drop of capillary blood is usually contaminated with interstitial or tissue
fluid, which can dilute the specimen and alter test accuracy. Wiping it away ensures a
more accurate sample for analysis. The other options are incorrect because
anticoagulants are not present in capillary collection, platelet activation is not the
primary concern at this step, and hemolysis is unrelated to the reason for discarding
the first drop.
QUESTION 2
Capillary blood is placed in circles on special filter paper primarily for which
diagnostic test?
A. Glucose tolerance test
B. PKU screening
C. Blood culture
D. Coagulation profile
Correct Answer: B. PKU screening
Rationale:
Phenylketonuria (PKU) screening uses dried blood spots collected on filter paper,
commonly from newborns. This method allows early detection of metabolic disorders.
,2026/2027
The other tests require liquid venous blood samples and cannot be performed using
dried blood spots.
QUESTION 3
Complete clotting of a freshly collected blood specimen typically occurs within:
A. 5 minutes
B. 10 minutes
C. 30 minutes
D. 2 hours
Correct Answer: C. 30 minutes
Rationale:
Blood typically requires about 30 minutes at room temperature to fully clot,
depending on patient condition and tube type. Faster or slower clotting may indicate
abnormalities. The other time frames are not physiologically accurate for complete
clot formation.
QUESTION 4
Petechiae observed when a tourniquet is applied indicate:
A. Normal capillary response
B. Excessive bleeding tendency
C. Dehydration
D. Hypertension
Correct Answer: B. Excessive bleeding tendency
Rationale:
Petechiae are tiny red spots indicating capillary fragility or platelet disorders,
suggesting a risk of excessive bleeding. They are not a normal response and are
unrelated to hydration status or blood pressure.
QUESTION 5
The instrument used to help visualize veins during venipuncture is called:
A. Hemoscope
B. Venoscope
,2026/2027
C. Dermatoscope
D. Spectroscope
Correct Answer: B. Venoscope
Rationale:
A venoscope uses light to illuminate veins, making them easier to locate, especially in
difficult venous access cases. The other instruments are used in unrelated diagnostic
fields.
QUESTION 6
The tourniquet should be placed approximately how far above the venipuncture site?
A. 1 inch
B. 2 inches
C. 3–4 inches
D. 6 inches
Correct Answer: C. 3–4 inches
Rationale:
Placing the tourniquet 3–4 inches above the site provides optimal venous
engorgement without causing excessive stasis. Too close or too far may compromise
vein selection or blood flow.
QUESTION 7
Which tube is most commonly used for coagulation studies?
A. Red top
B. Lavender top
C. Light blue top
D. Green top
Correct Answer: C. Light blue top
Rationale:
Light blue tubes contain sodium citrate, which preserves clotting factors for
coagulation testing such as PT and aPTT. Other tubes contain different additives
unsuitable for coagulation analysis.
QUESTION 8
, 2026/2027
After filling the last collection tube, the phlebotomist should:
A. Remove tourniquet first
B. Remove the filled tube from holder
C. Apply pressure immediately
D. Recap the needle
Correct Answer: B. Remove the filled tube from holder
Rationale:
Once the final tube is filled, it should be safely removed before proceeding with
needle withdrawal and site care. Proper sequence prevents contamination and injury.
QUESTION 9
A 20-degree angle during venipuncture is:
A. Correct
B. Too shallow
C. Too steep
D. Unsafe
Correct Answer: B. Too shallow
Rationale:
The correct insertion angle is typically 15–30 degrees, but standard practice is closer
to 30 degrees. A 20-degree angle may be too shallow for proper vein entry depending
on vein depth.
QUESTION 10
If blood is not obtained after needle insertion, the best action is to:
A. Remove needle immediately
B. Gently advance or adjust slightly
C. Apply pressure
D. Switch arms immediately
Correct Answer: B. Gently advance or adjust slightly
Rationale:
Small adjustments can help reposition the needle within the vein. Immediate removal
or switching sites may cause unnecessary trauma and multiple punctures.
