What is the primary purpose of an electronic thermometer?

• A. To measure blood pressure
• B. To assess heart rate
• C. To measure body temperature
• D. To evaluate lung function

Answer: (C)

The primary purpose of an electronic thermometer is to measure body temperature. This instrument provides a quick and efficient way to determine whether an individual has a fever or is experiencing normal temperature fluctuations, which is crucial for diagnosing various medical conditions. Monitoring body temperature is a fundamental aspect of assessing health, as it can indicate the presence of infection or other illnesses affecting homeostasis.

In contrast, the other options focus on different vital signs or functions that are not within the scope of what a thermometer is designed to measure. Blood pressure is assessed through sphygmomanometers or digital monitors, heart rate is determined through pulse oximeters or ECGs, and lung function tests require specialized equipment like spirometers. Each of these tools serves a distinct purpose that complements the information gathered from measuring body temperature.
