Which of the following is a sign of diminished nutritional status in surgical patients?

Diminished nutritional status in surgical patients can significantly impact various physiological processes. One of the key indicators of inadequate nutrition is delayed wound healing. When a patient does not receive sufficient nutrients, particularly proteins, vitamins, and minerals, their body struggles to repair tissues effectively after surgical procedures.

Wound healing is a complex process that requires adequate nutrition to support cell growth, immune function, and collagen synthesis, among other critical mechanisms. Nutritional deficiencies can lead to slowed or incomplete healing, increasing the risk of complications such as infections, dehiscence, or further surgical interventions.

In contrast, signs such as improved immune function, wound healing, or increased energy levels would typically indicate that the nutritional status is adequate or even favorable. Therefore, delayed wound healing serves as a clear and concerning sign of diminished nutritional status in surgical patients.
