Why do you place a 2x2 gauze or cotton ball over the injection site when you withdraw the needle during an intramuscular or subramuscual injection?

Placing a 2x2 gauze or cotton ball over the injection site when withdrawing the needle helps to prevent bleeding and minimize the risk of hematoma formation. It also provides a barrier to reduce the risk of infection and allows for immediate pressure application to the site, promoting clotting. This practice ensures patient comfort and safety during the injection process.
