10. a nurse is teaching a caregiver about the use of a vacuum-assisted closure system. how should the nurse instruct the caregiver to apply the foam strips?

It's simple, the first thing the nurse should explain is that the foam strips are a piece that is inserted into the wound, along with a drainage mechanism on top of them.
It is covered with a transparent adhesive membrane to fix both parts to the healthy skin around the wound margin, which also prevents air from forming and allows a partial vacuum to form inside the wound to facilitate drainage.Finally, it must emphasize that the foam is important to avoid obstruction of the drainage by contact with the base or the edges of the wound and eliminates the theoretical possibility of localized areas of high pressure and the consequent apoptosis or cell death
