Which instrument is commonly used by medical personnel to inject medicines?

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

Answer: (C)

Injecting medicines requires a device that can hold a specific amount of liquid and deliver it precisely through a needle into the body. The syringe provides a hollow barrel with a plunger to draw up and push out the medicine, and it typically uses a needle to pierce the skin and reach tissue or a vein. This design makes it capable of delivering injections in a controlled, sterile way and supports different routes like subcutaneous, intramuscular, and intravenous administration. The other items serve different purposes: a bandage covers wounds, a stethoscope listens to internal sounds, and a thermometer measures body temperature. Because only the syringe is built to inject medicines, it is the instrument used for that purpose.
