Which statement best describes signs of hypoglycemia in a conscious patient and its basic immediate treatment?

• A. Dizziness, fatigue, and blurred vision without sweating; treat with rest.
• B. Sweating, tremors, confusion, pallor, tachycardia; treat with fast-acting carbohydrate (glucose) and recheck.
• C. Chest pain with diaphoresis; treat as possible myocardial infarction.
• D. Severe dehydration with hypotension; treat with IV fluids.

Answer: (B)

Hypoglycemia in a conscious patient presents with sympathetic and neuroglycopenic signs, reflecting a drop in blood glucose and the body's attempt to raise it. The combination of sweating, tremors, pallor, and tachycardia shows autonomic activation, while confusion or altered mental status signals the brain not getting enough glucose. The key immediate move is to give a fast-acting carbohydrate to raise the blood glucose quickly, such as glucose tablets, fruit juice, regular soda, or glucose gel, and then recheck the blood glucose in about 15 minutes. If still low, repeat the quick-acting carbohydrate and reassess. Once the level is back in a safer range, follow with a longer-acting carbohydrate or a small snack to maintain glucose and prevent recurrence. If the patient could not swallow or were unconscious, the approach would shift to glucagon or IV dextrose, but for a conscious patient, the quick sugar and recheck sequence is the standard first step.
