The nurse is taking care of a post-surgical patient and notes the incision is clean and dry, with sutures intact. The nurse further assesses that the wound is healing by:

Second intention.

Fourth intention.

Third intention.

First intention.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Healing by second intention occurs when a wound is left open and allowed to close by granulation, epithelialization, and contraction. This method is used for wounds that are infected, have lost tissue, or where there is a delay in suturing. It is not applicable in this case as the wound is sutured and healing cleanly.

Choice B rationale
There is no recognized method of wound healing known as fourth intention. This option does not exist in medical terminology related to wound healing and is therefore not a correct choice.

Choice C rationale
Third intention, also known as delayed primary closure, is when a wound is initially left open due to contamination or infection and is not closed until it is clean. This is not the case here as the wound has been sutured closed from the beginning.

Choice D rationale
First intention, also known as primary intention, is when a clean wound is immediately closed with sutures, staples, or adhesive, leading to minimal scarring. This is the method described in the scenario, where the post-surgical wound is clean, dry, and the sutures are intact, indicating healing by first intention. This method is typically used for surgical incisions under sterile conditions.

Correct Answer is C

Explanation

Choice A rationale
Excessive gas is not typically an indication of wound dehiscence. While it may cause discomfort, it does not suggest that the wound layers have separated.

Choice B rationale
A complaint of constipation is a common postoperative concern due to decreased mobility and use of narcotics but is not a sign of wound dehiscence.

Choice C rationale
Increased drainage from the wound, especially if the fluid is clear or serous, can be an early sign of dehiscence, indicating that the wound layers are separating and fluid is accumulating.

Choice D rationale
Increased pallor of the surgical site might indicate poor perfusion but is not a direct sign of dehiscence. Dehiscence would more likely show signs of inflammation or unusual discharge.

A. Drawing the wound edges together using negative pressure. B. Strengthening the wall of the wound. C. Interrupting the proliferation of bacteria in the wound. D. Making and air occlusive cover for the wound

Correct Answer is A

Explanation

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.
