Which signs indicate hypoglycemia in an alert patient, and how should you respond?

• A. Anxiety, tremors, sweating, pallor, tachycardia, confusion; if able, give oral glucose or glucose gel; if unable to swallow or unconscious, contact EMS and consider IV or IM glucose per protocol
• B. Chest pain with nausea; give aspirin
• C. Dizziness only; drink water
• D. Rapid pulse with tingling; wait

Answer: (A)

Recognizing hypoglycemia in an alert patient relies on the characteristic autonomic symptoms that come from a drop in blood glucose. The signs—anxiety or nervousness, tremors, sweating, pale skin, and a rapid heart rate—often appear early as the body tries to raise blood glucose. If glucose continues to fall, neuroglycopenic symptoms like confusion can follow. The correct response is to provide fast-acting carbohydrates while the patient can still swallow safely. Give oral glucose or glucose gel so the body can quickly absorb sugar and raise blood glucose. If the patient can’t swallow or isn’t protecting their airway (for example, if they become drowsy or unconscious), do not give more food or drink. Instead, summon EMS and follow protocol for alternate glucose delivery—typically IV dextrose or intramuscular glucagon if you’re trained and authorized to administer it. This approach is specific to hypoglycemia and aims to restore normal glucose quickly. Other scenarios—like chest pain with nausea (suggestive of a cardiac event needing aspirin), dizziness alone (insufficient to guide treatment), or a rapid pulse with tingling followed by waiting—do not reflect the appropriate signs or the recommended immediate actions for hypoglycemia and could delay life-saving care.
