Which of the following is a treatment option for wound infections?

Drainage and culture is an effective treatment option for wound infections because it directly addresses the underlying problem. When a wound is infected, it often contains pus, bacteria, and necrotic tissue. Drainage allows for the removal of these harmful substances, which can alleviate pressure, reduce pain, and promote healing.

Culturally, taking a sample from the wound can help identify the specific pathogens causing the infection. This information is crucial because it guides the selection of appropriate antibiotics, ensuring that the treatment is targeted and effective.

Other options, such as observation only, may delay necessary treatment and allow the infection to worsen. Increasing activity levels is not relevant to the treatment of wound infections and could even exacerbate the condition by placing additional stress on the affected area. Similarly, while applying heat packs might have some applications for muscle relaxation or pain relief, it is not a standard or advisable treatment for wound infections, as heat can potentially worsen infection by promoting bacterial growth. Therefore, drainage and culture align directly with the essential principles of infection management in perioperative nursing care.
