Which vital sign measurement indicates body temperature?

The measurement that indicates body temperature is temperature itself. Body temperature is a vital sign that reflects the body's ability to generate and dissipate heat. It is measured in degrees, commonly using thermometers, and it provides essential information about a person's physiological status. Maintaining a normal body temperature is crucial for metabolic processes, and any significant deviations from the normal range can indicate illness or infection.

The other choices relate to different vital signs: pulse refers to the rate at which the heart beats, heart rate measures the number of heartbeats per minute, and respiration assesses the number of breaths taken. While all these vital signs are important for evaluating a person's health, they do not specifically indicate body temperature. Only the measurement explicitly stated as "temperature" directly pertains to assessing bodily heat.
