What is the term for a hollow tube through which blood or other body fluids may be withdrawn or substances administered?

• A. Catheter
• B. Luer lock
• C. Vascular access port
• D. Tether

Answer: (A)

A catheter is a hollow tube designed to be placed into the body to withdraw fluids or administer substances. It’s used for intravenous therapy, blood draws, urinary drainage, and other access needs, making it the exact term for the tube itself. Luer lock refers to a type of connector used to secure fittings, not the tube. A vascular access port is an implanted device with a reservoir connected to a catheter for repeated access, not the hollow conduit itself. A tether is a strap or cord, not a medical tube.
