To promote healing, a surgical wound must have all of the following requisites EXCEPT
- A.
Suture closure of dead space
- B.
Drains to remove fluid or air
- C.
A moderately tight dressing
- D.
Tight sutures to create tension
Correct Answer
D. Tight sutures to create tensionExplanation
The correct answer is tight sutures to create tension. While all the other options listed promote healing of a surgical wound, tight sutures that create tension can actually hinder healing. Tension on the wound edges can impair blood flow and increase the risk of wound dehiscence (splitting open) or poor scar formation. Therefore, it is important to avoid excessive tension when closing a surgical wound.Rate this question:

Wound healing that employs a technique allowing the would to heal from the bottom up is called
- A.
Interrupted intention
- B.
First intention
- C.
Second intention
- D.
Third intention
Correct Answer
C. Second intentionExplanation
Second intention wound healing refers to the healing process where a wound is left open to heal from the bottom up. This technique is used for larger wounds with a significant loss of tissue or when primary closure is not possible. The wound is allowed to heal by granulation, contraction, and epithelialization. This process takes longer compared to primary intention healing, where the wound edges are closed together with sutures. Interrupted intention, first intention, and third intention are not valid terms used in wound healing.Rate this question:
