Certified Medical-Surgical Registered Nurse Practice Exam

How should a nurse assess a patient's nutritional status in relation to wound healing?

1. By checking serum creatinine levels

2. By evaluating the total lymphocyte count

3. By measuring blood glucose levels

4. By tracking weight loss trends

The correct answer is: By evaluating the total lymphocyte count

The assessment of a patient's nutritional status in relation to wound healing is crucial because proper nutrition significantly impacts the body's ability to heal. Evaluating the total lymphocyte count serves as an effective indicator in this context. Lymphocytes are a type of white blood cell that play a vital role in the immune response and wound healing process. A low total lymphocyte count can indicate malnutrition and might suggest compromised immune function, which can impair wound healing. In particular, malnutrition can lead to a reduction in the body’s overall protein stores, essential for tissue repair, and a decrease in immune response, which are both important factors in the healing process. Thus, monitoring the total lymphocyte count can provide valuable insights into the patient's nutritional status and their potential for effective wound healing. While other options might be relevant in assessing overall health or specific conditions, they are not as directly linked to evaluating nutritional status in the context of wound healing as the total lymphocyte count. Weight loss trends can indicate nutritional deficits, but they do not provide specific information on lymphocyte viability or immune function, which are critical for healing. Blood glucose levels are important for diabetic patients but don't inherently reflect nutritional status in relation to wound healing. Serum creatinine levels primarily assess kidney function and
