Which object is used to administer injections or withdraw fluids?

• A. Syringe
• B. Stethoscope
• C. Thermometer
• D. Bandage

Answer: (A)

The device used to administer injections or withdraw fluids is the syringe. It has a hollow barrel and a plunger; pulling the plunger draws fluid into the barrel from a vein, tissue, or a vial, and pushing it forces the fluid out through a needle attached to the end. This ability to both draw and deliver fluids is what makes it the standard tool for injections and for drawing samples. A stethoscope, by contrast, is for listening to internal body sounds like the heart and lungs. A thermometer measures body temperature, and a bandage is used to cover and protect wounds. None of these perform injections or fluid withdrawal, so the syringe is the correct choice.
