, Phlebotomy Exam 2026/2027: 180 Questions & Answers
SECTION 1: VENIPUNCTURE PROCEDURES AND SITE SELECTION
Questions 1–15
Question 1
What is the most preferred site for venipuncture in adult patients?
A. Cephalic vein
B. Basilic vein
C. Median cubital vein
D. Dorsal venous arch
Answer: C. Median cubital vein
Explanation: The median cubital vein is the preferred venipuncture site because it is typically
large, well-anchored, and less likely to roll during needle insertion. It has fewer adjacent nerves,
reducing patient discomfort.
Question 2
When performing venipuncture on a 3-year-old child, which veins should be the first choice?
A. Median cubital vein
B. Basilic vein
C. Dorsal veins of the hand
D. Femoral vein
Answer: C. Dorsal veins of the hand
Explanation: For young children, dorsal hand veins are often preferred because antecubital
veins may be less developed, less visible, or obscured by subcutaneous tissue. Hand veins are
more superficial and easier to visualize.
Question 3
Which veins should generally be avoided unless specifically instructed by a physician?
A. Cephalic vein
B. Basilic vein
,C. Dorsalis pedis
D. Median cubital vein
Answer: C. Dorsalis pedis
Explanation: The dorsalis pedis vein (foot) is typically avoided due to increased risk of
complications including thrombophlebitis, infection, poor healing, and deep vein thrombosis
risk, particularly in patients with diabetes or peripheral vascular disease.
Question 4
What is the recommended needle gauge for donor phlebotomy in a blood bank setting?
A. 25 gauge
B. 22 gauge
C. 18–16 gauge
D. 27 gauge
Answer: C. 18–16 gauge
Explanation: Larger gauge needles (16–18) are required for blood donation to allow adequate
flow rate (approximately 75–100 mL/min) without causing hemolysis.
Question 5
For an older adult patient with difficult-to-access veins, which veins are most appropriate?
A. Basilic vein
B. Dorsal veins of the hand
C. Median cubital vein
D. Cephalic vein in the antecubital fossa
Answer: B. Dorsal veins of the hand
Explanation: Dorsal hand veins are often more accessible in older adults as antecubital veins
may be sclerosed, fragile, or deeply located due to decreased skin turgor. Hand veins are more
superficial and easier to stabilize.
Question 6
What is the proper way to anchor a vein just before needle insertion?
A. Place the thumb 1–2 cm above the puncture site pulling the skin taut
B. Use the thumb to anchor the vein 5 cm (2 inches) below the puncture site
, C. Place fingers on both sides of the vein
D. Apply pressure directly over the vein
Answer: B. Use the thumb to anchor the vein 5 cm (2 inches) below the puncture site
Explanation: Anchoring approximately 5 cm below the intended puncture site stabilizes the vein
and prevents rolling, while stretching the skin for smoother entry.
Question 7
When using an evacuated tube system, what angle should the needle be positioned?
A. 5–10 degrees
B. 15–30 degrees, bevel up, aligned with vein direction
C. 45–60 degrees
D. 90 degrees
Answer: B. 15–30 degrees, bevel up, aligned with vein direction
Explanation: A 15–30 degree angle with bevel up allows smooth venous entry, reduces patient
discomfort, and minimizes vein damage.
Question 8
What is a winged infusion (butterfly) needle typically used for?
A. Donor phlebotomy
B. Patients with fragile or small veins
C. All routine venipunctures
D. Capillary punctures
Answer: B. Patients with fragile or small veins
Explanation: Butterfly needles (21–25g) provide greater control and are ideal for small, fragile,
or rolling veins, as well as pediatric and geriatric patients.
Question 9
What is the maximum recommended tourniquet application time before release?
A. 30 seconds
B. 60 seconds (no longer than 1 minute)
C. 90 seconds
D. 120 seconds
