Final answer:
Transparent film dressings are best suited for stage 1 pressure injuries as they maintain a moist environment for healing and provide a barrier, unlike dressings for more advanced wounds.
Step-by-step explanation:
The appropriate dressing to promote healing in stage 1 pressure injuries is B) Transparent film dressings. These dressings are designed to be semi-permeable, which allows for exchange of moisture vapor and oxygen while providing a protective barrier against external contamination. They also facilitate a moist healing environment which is beneficial for the management of non-exudative wounds. Stage 1 pressure injuries are characterized by intact skin with non-blanchable redness. Wound dressings like hydrocolloid, alginate, or foam dressings are typically used for more advanced stages of pressure injuries that involve broken skin or more exudate.
