Wound, Ostomy and Continence Nurses Society (WOCN) Practice Exam

Which of the following is NOT one of the principles of topical therapy?

1. Maintain a moist wound surface

2. Protect the wound from irritation

3. Absorb excess exudate

4. Insulate to enhance cellular activity

The correct answer is: Protect the wound from irritation

The principle of protecting the wound from irritation is not specifically classified as one of the core principles of topical therapy. While it is important to minimize irritation and discomfort for optimal healing, the primary principles focus more on the conditions that directly influence the healing environment of the wound. Maintaining a moist wound surface is critical because it facilitates cellular migration and aids in the healing process by preventing the tissue from drying out. A moist environment can also reduce pain and scarring while promoting the breakdown of necrotic tissue. Absorbing excess exudate is another essential principle. Proper management of exudate helps prevent maceration of the surrounding skin, reduces infection risk, and maintains an optimal healing environment. Insulating to enhance cellular activity is also vital, as it helps to maintain a stable temperature that supports the metabolic processes necessary for healing. Therefore, while protecting the wound from irritation is an important consideration in wound care, it does not fall under the standard principles of topical therapy as directly as the other choices do.
