When evaluating the client's temperature levels, the nurse expects the client's temperature to be lower:
Correct answer
A
Rationale
The correct answer is A: In the morning. The body temperature is typically lower in the early morning due to the circadian rhythm, reaching its lowest point around 4-6 a.m. This is known as the nadir of the circadian temperature rhythm. During sleep, the body's metabolic rate decreases, leading to lower body temperature. Choices B, C, and D are incorrect because stress, exercise, and the preoperative period can all lead to an increase in body temperature due to hormonal responses, increased metabolism, and stress-induced physiological changes.
