**Question:** All of the following are causes of postoperative wound dehiscence except-

A. Poor surgical technique
B. Inadequate local wound care
C. Nutritional deficiency
D. Infection

**Core Concept:**

Postoperative wound dehiscence is a condition characterized by the breakdown or separation of the surgical incision, leading to potential complications such as infection, prolonged healing, and increased morbidity. This question is testing the understanding of factors contributing to wound dehiscence, excluding one cause that is not relevant to this issue.

**Why the Correct Answer is Right:**

The correct answer, **Nutritional deficiency (C)**, is not a direct cause of postoperative wound dehiscence. While malnutrition can weaken the immune system and increase the risk of infections, it does not directly compromise the structural integrity of the surgical wound. Inadequate nutrition can indirectly affect wound healing by impairing collagen synthesis and matrix remodeling, but it is not the primary cause of dehiscence itself.

**Why Each Wrong Option is Incorrect:**

A. **Poor surgical technique (A)** is a direct cause of postoperative wound dehiscence, as inadequate surgical skills can lead to insufficient tissue apposition, poor hemostasis, and increased tension on the sutures or staples, compromising the wound stability.

B. **Inadequate local wound care (B)** can contribute to wound dehiscence by delaying the healing process, increasing the risk of infection, and causing local inflammation. However, it is not the primary cause of dehiscence but rather an additional factor that can exacerbate the problem.

D. **Infection (D)** is a significant cause of postoperative wound dehiscence, as bacterial invasion can lead to tissue necrosis, impaired healing, and ultimately dehiscence.

**Clinical Pearl:**

Proper wound care and infection prevention are essential in reducing the risk of postoperative wound dehiscence. Surgical teams should focus on mastering surgical technique, maintaining aseptic practices, and promptly addressing any signs of infection, such as redness, swelling, or discharge. Additionally, ensuring adequate nutrition and addressing local wound care factors can help optimize the healing process and minimize the risk of dehiscence.

**Correct Answer:**

**Correct Answer: Nutritional deficiency (C)**
