Which statement is true about venipuncture?

Which statement is true about venipuncture?

• A. It withdraws blood from a vein
• B. It withdraws blood from an artery
• C. It collects urine
• D. It samples from capillaries

Answer: (A)

Venipuncture involves accessing a vein to draw blood for testing. That’s why the statement about withdrawing blood from a vein is correct. Arteries are used in arterial puncture, not venipuncture, and involve a different technique. Urine collection is a completely different type of specimen, and capillary sampling (like a fingerstick) draws from small vessels in the periphery, not a vein. So the true description is that venipuncture withdraws blood from a vein.
