1. Which vein is the first choice for routine venipuncture?
Answer: Median cubital vein
Rationale: Large, well-anchored, least painful, avoids
nerves/arteries.
Scenario: Patient with small, rolling veins → you palpate a
bouncy vein in the center of antecubital fossa → median
cubital.
,Page 2 of 94
2. Which artery lies deep to the basilic vein?
Answer: Brachial artery
Rationale: Brachial artery runs alongside basilic vein;
accidental puncture causes pulsatile hematoma.
Scenario: After failed basilic draw, patient develops rapid
swelling and throbbing pain → brachial artery puncture
suspected.
3. What is the primary function of platelets?
Answer: Clotting (hemostasis)
Rationale: Platelets aggregate at injury sites to form a plug.
Scenario: A patient with easy bruising and prolonged
bleeding after a small cut → likely thrombocytopenia.
4. Which tube additive inhibits glycolysis?
Answer: Sodium fluoride
Rationale: Preserves glucose for up to 72 hours by inhibiting
enolase.
,Page 3 of 94
Scenario: Fasting glucose and lactate ordered → gray-top
tube with NaF/KOx.
5. The left ventricle pumps blood into which vessel?
Answer: Aorta
Rationale: Left ventricle → aorta → systemic circulation.
Scenario: Aortic stenosis patient syncopes during venipuncture
→ reduced cardiac output from narrowed valve.
6. What is the function of the pulmonary vein?
Answer: Carries oxygenated blood from lungs to left atrium
Rationale: Only vein carrying oxygenated blood.
Scenario: Patient with left atrial enlargement → increased
pressure in pulmonary veins → possible pulmonary congestion.
7. Which layer of a blood vessel does the needle pierce first?
Answer: Tunica intima
Rationale: Needle passes through skin, then tunica intima
(innermost layer) into lumen.

Scenario: Intimal damage from large-gauge needle →

9. Which nerve is near the cephalic vein at the wrist?
M. M. M. M. M. M. M. M. M.
M. Answer: Superficial branch of radial nerve
M. M. M. M. M.
Rationale: Can cause shooting pain if punctured.

10. What is the normal pH range of arterial blood?
M. M. M. M. M. M. M. M.
Answer: 7.35–7.45 M.
Rationale: Acid-base balance maintained by lungs and
M. M. M. M. M. M.
M. kidneys.
