Why is applying pressure with gauze for several minutes after needle withdrawal important?

• A. To stop bleeding and prevent hematoma formation
• B. To disinfect the site
• C. To numb the area
• D. To clean the skin

Answer: (A)

After withdrawing the needle, the goal is to achieve hemostasis at the puncture site. Applying firm pressure with gauze for several minutes provides mechanical compression that slows and stops the blood flow, giving platelets time to form a clot and seal the vessel. This helps prevent bleeding and the development of a hematoma under the skin. The gauze pressure isn’t about disinfecting, numbing, or cleaning—the site is prepared and cleaned before puncture, and numbness is achieved with anesthesia if needed. If bleeding persists, additional pressure may be applied, but the primary purpose here is to stop bleeding and minimize hematoma risk.
