Question 1 of 5
A patient's body temperature has varied over the last 24 hours from 97.6 degrees F in the morning to 99 degrees F in the evening. The patient is worried that this change in temperature may indicate the beginning of a fever. Which of the following BEST explains this phenomenon?
Correct Answer: B
Rationale: The patient is experiencing changes related to a diurnal rhythm. Diurnal rhythm is the phenomenon of body temperature fluctuating depending on the time of day. Temperatures taken in the morning are typically lower than those taken throughout the rest of the day.
Choice A is incorrect because a single elevated temperature reading in the evening does not definitively indicate a fever.
Choice C is incorrect as there is no indication of incorrect temperature measurement.
Choice D is incorrect as the temperature changes are not related to monthly hormones but rather to the body's natural daily rhythm.
