Final answer:
Transparent film dressings are used to promote healing in stage 1 pressure injuries by preventing further friction and shearing, ideal for intact skin with non-blanchable redness.
Step-by-step explanation:
Transparent film dressings promote healing in stage 1 pressure injuries by preventing further friction and shearing. These dressings are designed to be thin and self-adhesive, which allows them to maintain a moist wound environment that can facilitate healing while also serving as a barrier against external contaminants. Unlike other types of dressings, transparent film is non-absorbent but still provides a protective layer over the injury. A stage 1 pressure injury, also known as a pressure ulcer or bedsore, is characterized by intact skin with non-blanchable redness. Since the skin is intact and there's no need for absorption, transparent film is often the preferred choice for managing these injuries.
