Which instrument is used to measure body temperature?
Appeared in: CGHS SSC - 2018
Explanation
- A thermometer is the designated medical instrument for measuring body temperature.
- Clinical thermometers work by various mechanisms, including electronic sensors (digital thermometers) or infrared technology (tympanic and temporal thermometers).
- Accurate temperature measurement is a fundamental component of assessing a patient's vital signs and overall health status.
Why Other Options Were Wrong
- Option A: A sphygmomanometer is used to measure blood pressure, not temperature.
- Option C: A barometer is a meteorological instrument used to measure atmospheric pressure for weather forecasting.
- Option D: A vitalometer is not a standard clinical instrument for measuring body temperature or other primary vital signs. The term is sometimes associated with dental pulp testing.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of common medical and non-medical measurement instruments as background academic context rather than a clinical decision trigger.
- Accurate temperature measurement is critical for detecting fever (pyrexia) or hypothermia, which are key indicators of infection, inflammation, or environmental exposure.
- Monitoring temperature trends helps nurses evaluate the effectiveness of treatments, such as antibiotics for an infection or warming measures for hypothermia.
- The choice of thermometer and measurement site depends on the patient's age, clinical condition, and level of consciousness. For example, the rectal route is most accurate for infants, while the oral route is contraindicated in an unconscious patient.
