, This exam is designed to assess essential knowledge and practical decision-making in intravenous therapy
and blood withdrawal. It measures understanding of anatomy, equipment selection, aseptic technique, safe
blood collection, specimen labeling, and complication prevention. The questions combine multiple-choice and
scenario-based formats to reflect real clinical situations encountered during IV cannulation and
venipuncture. Emphasis is placed on correct technique, patient safety, professional conduct, legal
responsibilities, and quality assurance. The assessment is intended to help learners apply theory to practice
with confidence, accuracy, and sound clinical judgment.
. Which vein is usually the easiest to puncture in the antecubital fossa?
A. Basilic vein
B. Cephalic vein
C. Median cubital vein
D. Median basilic artery
🟢 Correct answer: C. Median cubital vein
🔴 RATIONALE: The median cubital vein is typically large, well anchored, and less likely to move, making it
the preferred site for venipuncture.
. Before inserting a needle for routine venipuncture, what is the recommended skin antiseptic when blood
cultures are not being drawn?
A. 70% alcohol
B. Povidone-iodine only
C. Sterile water
D. Saline
, 🟢 Correct answer: A. 70% alcohol
🔴 RATIONALE: Routine blood collection uses 70% alcohol for skin disinfection, and the site should be
allowed to dry fully before puncture.
. How long should alcohol generally be allowed to dry on the skin before venipuncture?
A. 5 seconds
B. 10 seconds
C. 30 seconds
D. 2 minutes
🟢 Correct answer: C. 30 seconds
🔴 RATIONALE: Drying time is important to reduce contamination and improve antiseptic effectiveness; WHO
guidance specifies about 30 seconds.
. Which action best helps reduce hematoma formation after venipuncture?
A. Ask the patient to bend the arm
B. Apply firm pressure after needle removal
C. Massage the site immediately
D. Remove the gauze after 10 seconds
🟢 Correct answer: B. Apply firm pressure after needle removal
, 🔴 RATIONALE: Direct pressure helps stop bleeding and prevents blood from leaking into surrounding tissue,
reducing hematoma risk.
. Which instruction should the patient follow immediately after venipuncture?
A. Keep the arm bent tightly
B. Rub the puncture site
C. Hold gauze in place with the arm extended
D. Remove the dressing if pain occurs
🟢 Correct answer: C. Hold gauze in place with the arm extended
🔴 RATIONALE: Keeping the arm extended and applying gentle pressure reduces bruising and avoids
hematoma formation.
. Which statement about tourniquet use is correct?
A. It should remain in place until after the patient leaves
B. It should be released before withdrawing the needle
C. It should be applied only after needle insertion
D. It should remain on for at least 5 minutes
🟢 Correct answer: B. It should be released before withdrawing the needle
🔴 RATIONALE: Prolonged tourniquet time can alter results and increase complications; it should be released
before needle removal.
. Which practice is most appropriate for patient identification before blood withdrawal?
