What is a glucometer?

A device used to measure blood glucose levels. A device used to measure blood pressure. A device that measures body temperature. A device that listens to the heart.

Correct Answer:

A device used to measure blood glucose levels.

Explanation:

A glucometer is a handheld device that measures blood glucose levels. It uses a disposable test strip that detects glucose in a small drop of blood from a fingerprick, and the meter displays a numeric reading in mg/dL or mmol/L. This helps people track how diet, activity, and medications affect their blood sugar and guides decisions about meals, exercise, and treatment. In daily care, you might assist with obtaining the blood sample safely, applying it to the strip, reading and recording the result, and reporting anything out of the target range. It’s different from devices that check blood pressure, temperature, or heart sounds, which use a cuff, thermometer, or stethoscope, respectively.
