Which of the following is a sign of hypoglycemia in a resident with diabetes?

• A. Fever
• B. Shakiness
• C. Cough
• D. Headache

Answer: (B)

Low blood sugar triggers a surge of adrenaline, which causes trembling or shakiness. This symptom is a classic early sign of hypoglycemia in someone with diabetes, signaling that the glucose level is too low and quick action is needed to raise it.

Fever, cough, and headache are not specific indicators of low blood sugar. Fever suggests infection or illness, a cough points to respiratory issues, and headache is a non-specific symptom that can arise from many causes. So shakiness best fits the response to hypoglycemia and helps prompt timely treatment to prevent more serious problems. If you observe shakiness, assess blood glucose if possible and provide a fast-acting carbohydrate as appropriate.
