Which device is used to verify blood glucose during a hypoglycemic episode?

• A. Sphygmomanometer
• B. Glucose monitor
• C. Thermometer
• D. Stethoscope

Answer: (B)

During a hypoglycemic episode, quickly confirming the blood glucose level is essential to guide treatment. A glucose monitor is the device designed to measure blood glucose from a small finger-prick blood sample and provide a numeric reading, confirming whether glucose is low and by how much. This direct measurement tells you what to do next, such as giving a fast-acting carbohydrate if the level is low. Other devices measure different vitals—blood pressure (sphygmomanometer), body temperature (thermometer), or listen to the heart and lungs (stethoscope)—and they do not provide glucose readings, so they won’t verify hypoglycemia.
