The correct answer is the thermometer, which is specifically designed to measure body temperature. It functions by sensing heat content and providing a readout of the body's core temperature, which is critical for assessing a patient's health status.

Understanding the various tools used to monitor vital signs clarifies why the thermometer is the appropriate choice here. A stethoscope is primarily used for auscultation, allowing healthcare providers to listen to internal sounds of the body, such as heartbeats and lung sounds, but it does not measure temperature. The blood pressure cuff is utilized to measure blood pressure, providing important cardiovascular information, while a sphygmomanometer is specific for blood pressure readings as well. Neither of those devices is designed to assess body temperature, which is why they do not fit the question's criteria. Thus, the thermometer is the essential tool in evaluating a patient's temperature accurately.
