The nurse clarifies that a vacuum-assisted closure supports healing of a wound by:
Strengthening the wall of the wound.
Drawing the wound edges together by negative pressure.
Making an air occlusive cover for the wound.
Interrupting the proliferation of bacteria in the wound.
The Correct Answer is B
Choice A rationale:
Strengthening the wall of the wound is not the primary function of vacuum-assisted closure. The main function is to promote wound healing by applying negative pressure.
Choice B rationale:
Drawing the wound edges together by negative pressure is the correct answer. Vacuum-assisted closure, also known as negative pressure wound therapy, works by applying negative pressure to the wound, which helps to draw the edges of the wound together and promote healing.
Choice C rationale:
Making an air occlusive cover for the wound is not the primary function of vacuum-assisted closure. The main function is to promote wound healing by applying negative pressure.
Choice D rationale:
Interrupting the proliferation of bacteria in the wound is not the primary function of vacuum-assisted closure. The main function is to promote wound healing by applying negative pressure.
