, Phlebotomy Exam Prep 2026-2027: 150 Questions & Answers
SECTION A: PHLEBOTOMY FUNDAMENTALS AND TECHNIQUES
Question 1
A vein that feels hard and thready upon palpation is most likely:
A) Thrombosed
B) Sclerosed
C) Collapsed
D) Inflamed
Answer: B) Sclerosed
Explanation: A sclerosed vein has undergone fibrosis and hardening due to repeated
venipunctures, intravenous drug use, or disease processes. This condition makes the vessel non-
compliant and unsuitable for venipuncture due to its rigid, cord-like texture and compromised
blood flow.
Question 2
When a syringe plunger is retracted too rapidly during specimen collection, the resulting
complication is:
A) Hemoconcentration
B) Hematoma formation
C) Hemolysis
D) Lipemia
Answer: C) Hemolysis
Explanation: Excessive negative pressure created by rapid plunger withdrawal subjects red
blood cells to mechanical stress and sheer forces, causing their membranes to rupture. This
,releases intracellular contents, particularly potassium and hemoglobin, which interferes with
numerous laboratory assays.
Question 3
The recommended method for collecting blood from an infant who is less than one year old is:
A) Venipuncture of the cephalic vein
B) Capillary puncture of the heel
C) Arterial puncture of the radial artery
D) Venipuncture of the jugular vein
Answer: B) Capillary puncture of the heel
Explanation: Capillary puncture of the medial and lateral plantar surfaces of the heel is the
preferred method for neonatal and infant blood collection. This approach minimizes blood loss,
reduces the risk of major vessel injury, and is less traumatic than venipuncture in this patient
population.
Question 4
During a heel puncture procedure on an infant, the appropriate lancet placement is:
A) Directly on the center of the heel
B) Flat against the medial or lateral plantar surface
C) At a 45-degree angle on the posterior heel
D) On the arch of the foot
Answer: B) Flat against the medial or lateral plantar surface
Explanation: The lancet should be placed flat against the medial or lateral aspects of the plantar
heel surface. These areas are well-perfused with capillary beds while avoiding the calcaneus
bone, which lies directly beneath the center of the heel and poses a risk of osteomyelitis if
punctured.
, Question 5
The proper angle for needle insertion during routine venipuncture is:
A) 5-10 degrees
B) 15-30 degrees
C) 45-60 degrees
D) 75-90 degrees
Answer: B) 15-30 degrees
Explanation: Inserting the needle at a 15-30 degree angle allows for optimal entry into the
lumen of the vein while minimizing the risk of passing completely through the vessel or scraping
the vein wall. This shallow angle facilitates successful blood flow and reduces patient
discomfort.
Question 6
The primary reason for wiping away the first drop of blood during a capillary puncture procedure
is:
A) To remove surface contaminants
B) To stimulate better blood flow
C) To reduce tissue fluid contamination
D) To ensure adequate sample volume
Answer: C) To reduce tissue fluid contamination
Explanation: The initial drop of blood from a capillary puncture contains elevated levels of
interstitial and tissue fluid, which can dilute the specimen and alter analytical results. Wiping
away this first drop ensures that the subsequent sample more accurately reflects peripheral blood
composition.
