What is a common early sign of hypoglycemia in adults and the immediate action?

• A. Confusion; call for help
• B. Adrenergic symptoms like sweating and tremor; treat with rapid-acting glucose after confirmed
• C. Seizure; administer IV fluids
• D. Drowsiness; sleep it off

Answer: (B)

Early signs of hypoglycemia in adults are adrenergic symptoms, such as sweating and tremor, caused by the body's counterregulatory release of adrenaline to raise blood glucose. The best immediate action is to give rapid-acting glucose right away if the patient is conscious and able to swallow. Provide about 15–20 grams of fast-acting carbohydrate (for example, a small glass of juice, glucose tablets, or glucose gel) and recheck the blood glucose in about 15 minutes, repeating if still below normal. If the person cannot swallow or is unconscious, do not give oral carbohydrates—administer glucagon as ordered or start IV dextrose and seek help promptly.
