The nurse clarifies that a vacuum-assisted closure supports the healing of a wound by:

Choice A:
This position would not be ideal for right eye irrigation. Tilting the head towards the left eye could cause the irrigation solution to flow into the left eye, potentially causing discomfort or harm⁵.

Choice B:
While the supine position is correct, hyperextending the head is not necessary and could cause discomfort to the patient.

Choice C:
This position could cause discomfort to the patient and does not facilitate the flow of the irrigation solution away from the nose and mouth.

Choice D:
This is the correct position for right eye irrigation. The supine position with the head tilted toward the right eye allows the solution to flow away from the nose and mouth, preventing aspiration or discomfort.

Choice A rationale
Hydrocolloid dressings are not designed to keep a wound dry; instead, they maintain a moist environment which is conducive to wound healing. They absorb exudate and form a gel, which promotes granulation and epithelialization.

Choice B rationale
The primary purpose of a hydrocolloid dressing is to remain in place for an extended period, typically up to 7 days. This minimizes disturbance to the wound, reduces the risk of infection, and maintains a moist healing environment.

Choice C rationale
While hydrocolloid dressings can help prevent bacterial growth due to their occlusive nature, their main function is not to destroy microorganisms. They provide a barrier against external contaminants and support autolytic debridement.

Choice D rationale
The main purpose of hydrocolloid dressings is to promote a moist healing environment. They contain gel-forming agents that absorb exudate and maintain a moist wound bed, which facilitates faster healing and reduced scar formation.
