C) when the edges roll up and exudate leaks.

RATIONALE

Transparent film dressings on a clean, noninfected wound can be left in place for days, until the seal is broken, exudate leaks out, or the edges roll up. Older adults are at risk for skin breakdown. A nurse needs knowledge of what dressings are chosen and when they are changed. Consider the choices; when there are similarities, some choices can be eliminated.
