Which term means putting a needle into a vein and withdrawing blood?

• A. Phlebotomy
• B. Petechiae
• C. Permeability
• D. Pediatric

Answer: (A)

Phlebotomy is the practice of drawing blood from a vein for tests or other medical purposes. The word comes from vein (phlebo-) and cut/puncture (-tomy), reflecting the act of inserting a needle into a vein to withdraw blood. In a typical blood draw, a tourniquet helps locate a vein, a needle is inserted into the vein, blood is collected into tubes, and then the needle is safely removed with pressure applied to the site. The other terms don’t describe a procedure: petechiae are tiny spots caused by bleeding under the skin, permeability is about how substances pass through membranes, and pediatric relates to care of children.
