However, excessive moisture can damage surrounding skin, while an overly dry wound may delay tissue regeneration. Nurses should evaluate the amount of drainage, wound depth, and surrounding skin condition when selecting dressings. Appropriate dressing selection helps create ideal healing conditions while protecting healthy tissue and reducing the risk of wound-related complications.

Question 9: A patient asks why good nutrition is important during wound healing. Which response by the nurse is most appropriate?

A. Nutrition has very little effect on wound healing.
B. Adequate protein, calories, vitamins, and minerals help the body repair damaged tissue and support immune function.
C. Only fluid intake affects wound healing.
D. Nutritional needs remain unchanged regardless of wound severity.

Answer: B. Adequate protein, calories, vitamins, and minerals help the body repair damaged tissue and support immune function.

Explanation: Proper nutrition provides the building blocks necessary for tissue repair, collagen production, immune function, and overall recovery. Patients with chronic wounds often require increased protein and adequate calorie intake to support healing. Vitamins such as A and C, along with minerals like zinc, also contribute to tissue regeneration and immune defense. Nurses should assess nutritional status, identify patients at risk for malnutrition, collaborate with dietitians when appropriate, and educate patients about healthy dietary choices. Optimizing nutrition can significantly improve wound healing and reduce recovery time.

Question 10: Which nursing responsibility is most important when documenting wound care?

A. Recording only the dressing that was applied.
B. Accurately documenting wound size, appearance, drainage, interventions, and the patient’s response to treatment.
C. Waiting until discharge to complete wound documentation.
D. Estimating wound measurements without performing an assessment.

Answer: B. Accurately documenting wound size, appearance, drainage, interventions, and the patient’s response to treatment.

Explanation: Comprehensive wound documentation supports continuity of care, evaluates treatment effectiveness, and provides an accurate legal and clinical record. Nurses should consistently record wound measurements, tissue characteristics, drainage amount and type, condition of the surrounding skin, pain level, interventions performed, and the patient’s response to treatment. Consistent documentation allows healthcare providers to monitor healing progress, identify complications early, communicate effectively with the interdisciplinary team, and adjust the care plan when necessary. Accurate records are essential for delivering safe, evidence-based wound management and improving patient outcomes.
