Which of the following is an important part of the general treatment for a local infection?

The application of cold compresses can help reduce swelling and alleviate pain, but it does not address the underlying issue of the infection itself. Immobilizing the area may be beneficial in certain cases, especially if movement exacerbates pain, but it does not directly treat the infection. Immediate surgery is typically reserved for severe infections where there is significant tissue damage or abscess formation, and it is not a standard part of managing local infections for most cases.

Open and irrigate the wound is a critical step in the management of a local infection because it helps to remove foreign materials, debris, and bacteria from the wound site, promoting healing and reducing the risk of complications. Proper irrigation cleanses the area, providing a better environment for the body's natural healing mechanisms to function and allowing topical antimicrobials to work more effectively. This approach is fundamental in ensuring that an infection does not worsen or spread, making it the cornerstone of treatment in managing a local infection.
