Which tool is used to check blood sugar?

• A. Thermometer
• B. Stethoscope
• C. Oximeter
• D. Glucometer

Answer: (D)

To check blood sugar, you use a glucometer. This device reads glucose levels from a small amount of blood, usually obtained with a quick finger-stick. After you apply a drop of blood to a test strip, the meter shows the patient’s current blood glucose value. This is essential for PCT work because it helps monitor patients with diabetes, during illness, or when there are signs of low or high blood sugar, guiding needed interventions. The other tools measure different things: a thermometer checks body temperature, a stethoscope listens to the heart and lungs, and an oximeter measures oxygen saturation. They don’t measure glucose, so they aren’t used to check blood sugar.
