What is venipuncture?

• A. The withdrawal of blood from a vein
• B. The withdrawal of blood from an artery
• C. The collection of urine
• D. The injection of a medication

Answer: (A)

Venipuncture is the procedure of puncturing a vein to withdraw blood for laboratory testing. It’s the standard method for obtaining venous blood samples, usually done by inserting a needle into a superficial vein (often in the arm) and using collection tubes to draw the blood. This is distinct from puncturing an artery (used for arterial blood gases or specific tests), collecting urine, or injecting medication, which are different procedures.
