The nurse clarifies that a vacuum-assisted closure supports the healing of a wound by:
Drawing the wound edges together using negative pressure.
Strengthening the wall of the wound.
Interrupting the proliferation of bacteria in the wound.
Making and air occlusive cover for the wound
The Correct Answer is A
Choice A rationale
Vacuum-assisted closure (VAC) therapy aids in wound healing primarily by applying negative pressure to draw the wound edges together. This not only helps reduce the size of the wound but also promotes blood flow to the area, which can accelerate healing.
Choice B rationale
While VAC therapy does support the underlying structures of the wound, its primary function is not to strengthen the wall of the wound. The negative pressure assists in removing excess fluid and reducing edema, which indirectly supports the wound structure.
Choice C rationale
VAC therapy does have an impact on bacterial levels within the wound by helping to remove infectious materials. However, its main purpose is not to interrupt bacteria proliferation; this is more directly achieved through antibiotic therapy and proper wound care techniques.
Choice D rationale
While VAC does create a cover over the wound, its main purpose is to apply negative pressure to the wound area. This negative pressure helps to draw the wound edges together, promotes the removal of exudate and potentially infectious material, and stimulates the growth of new tissue, which aids in the healing process12. The occlusive cover is part of the system that allows the negative pressure to be maintained, but it is the negative pressure itself, not the cover, that provides the therapeutic benefit.

Correct Answer is ["A","B","C","E"]
Explanation
Choice A rationale
Inspecting the plug and cord for cracks or fraying is essential to prevent electrical hazards and ensure the safety of both the patient and healthcare staff.
Choice B rationale
Securing the pad to the patient helps to maintain the correct position and prevent burns or other injuries from improper pad placement.
Choice C rationale
Instructing the patient not to sleep on the pad is important because prolonged, direct contact with the heat source can cause burns, especially if the patient is immobile or has sensory deficits.
Choice D rationale
Assisting the patient to lie on top of the pad is not recommended as it can lead to burns due to increased temperature exposure in one area.
Choice E rationale
Using a thermometer to check the temperature of the pad ensures that it is within a safe range for application to the patient's skin, preventing burns.
Correct Answer is A
Explanation
Choice A rationale
The second stage of wound healing is proliferation, which occurs after the initial hemostasis phase. During proliferation, the wound begins to be rebuilt with new, healthy granulation tissue. This tissue is rich in collagen, which forms a foundation for new tissue growth. Capillaries grow across the wound, bringing oxygen and nutrients that are essential for healing. New skin cells begin to form over this granulation tissue, which is a critical component of the healing process.
Choice B rationale
Maturation is the third and final stage of wound healing. It follows the proliferation stage and involves the remodeling of collagen, which strengthens the tissue and restores its normal function. During maturation, the new tissue slowly gains strength and flexibility. Here, the collagen fibers reorganize, the tissue remodels and contracts, and the healed wound becomes more resilient. This stage can take a long time, sometimes up to a year or more, depending on the wound’s severity and the patient’s overall health.
Choice C rationale
Inflammation is indeed the second stage of wound healing. It is a natural part of the healing process and involves controlling bleeding, preventing infection, and enabling the migration of healing cells to the wound area.
Choice D rationale
Remodeling is the last stage of wound healing, not the second. It occurs after the wound has closed and involves the long-term strengthening and formation of scar tissue.
