What is the purpose of a glucometer?

  1. a. Measure blood pressure

  2. b. Monitor heart rate

  3. c. Test oxygen levels

  4. d. Measure blood sugar

The correct answer is: d. Measure blood sugar

A glucometer is a medical device used specifically to measure blood sugar levels. While it may seem like the purpose of this device is similar to those listed in the other options, it is important to note that blood pressure, heart rate, and oxygen levels are all separate physiological measurements and cannot be accurately measured using a glucometer. Therefore, these options are incorrect as they do not align with the specific purpose of a glucometer.
