Which of the following is classified as a nonadherent dressing?

Xeroform is classified as a nonadherent dressing because it is designed to minimize adherence to the wound, thereby reducing the risk of disturbing healing tissue when the dressing is changed. This type of dressing is made from a paraffin-based material that provides a protective barrier while allowing for a moist environment that can promote wound healing.

Nonadherent dressings are particularly useful in managing wounds where irritation or trauma to the healing tissue should be avoided. They are typically indicated for use on wounds that are at risk for sticking to the dressing material, which can cause pain and delay the healing process during dressing changes.

In contrast, gauze, Adaptic, and hydrocolloid dressings have varying levels of adherence that can cause them to stick to the wound, especially upon drying. Gauze, for instance, is often used in more fluid-heavy situations and can adhere to wounds. Adaptic has a mild adherence but is generally used to ensure a barrier without significant sticking. Hydrocolloid dressings can adhere well to the skin but are designed to maintain a moist environment, which may sometimes lead to adherence issues when removed.
