The question asks: Which of the following is a nursing diagnosis? The correct answer is A. Hypothermia. A nursing diagnosis refers to a clinical judgment about individual, family, or community experiences/responses to actual or potential health problems/life processes. Nursing diagnoses are recognized by the North American Nursing Diagnosis Association (NANDA) and are used to guide nursing care plans, while Hypothermia, unlike the other options listed, is a condition that can be directly managed with nursing interventions.
The options B. Diabetes Mellitus, C. Angina, and D. Chronic Renal Failure are all medical diagnoses. A medical diagnosis is identified by a medical professional and focuses on the disease itself, while a nursing diagnosis focuses on the patient's response to health conditions or needs.
