What type of equipment is used to measure temperature?

The correct choice, a thermometer, is specifically designed to measure temperature, whether it be body temperature, the temperature of liquids, or environmental temperature. Thermometers operate on the principle of thermal expansion, with various types such as digital, infrared, and mercury-based devices to provide accurate temperature readings.

In a healthcare setting, monitoring a patient’s body temperature is essential, as it can indicate the presence of illness or infection. Unlike other options, the thermometer is the only tool explicitly intended for this purpose, making it the most appropriate equipment for temperature measurement.

Other tools like a stethoscope, scales, and a blood pressure cuff serve entirely different functions. A stethoscope is used for listening to heart and lung sounds; scales measure weight; and a blood pressure cuff is used for measuring blood pressure. Each of these instruments plays a vital role in healthcare but does not contribute to temperature assessment.
