A nurse is caring for an alert adult client with type 1 diabetes who reports tremors, sweating, and palpitations 30 minutes after the morning insulin dose. Bedside capillary blood glucose is 52 mg/dL. Which action should the nurse take FIRST?

The Rule of 15 (15 g of fast-acting oral carbohydrate followed by a blood glucose recheck in 15 minutes) is the first-line treatment for symptomatic but conscious hypoglycemia in an alert adult who can swallow. Glucagon is reserved for clients who are unconscious, seizing, or unable to take oral intake. Notifying the provider is appropriate after stabilization, not as the first action. Withholding food worsens hypoglycemia and is contrary to recommended care.

<span class="merci-scenario-label">Clinical Judgment</span><br>The cue is a <span class="merci-kw">conscious adult with neuroglycopenic and adrenergic symptoms plus BG 52 mg/dL</span>. Recognize cues -> mild-to-moderate hypoglycemia in an alert client who can swallow. Analyze cues -> ADA Standards of Care: oral glucose first when alert.

Clinical scenario

<span class="merci-scenario-label">Clinical Practice Guide</span><br><span class="merci-kw">ADA Rule of 15</span> for conscious symptomatic hypoglycemia (<70 mg/dL): give 15 g of fast-acting carbohydrate (4 glucose tabs, 4 oz juice or regular soda, 1 tbsp honey or sugar). Recheck blood glucose in 15 minutes. If still <70, repeat. Once >70, follow with a complex carbohydrate + protein snack if the next meal is more than 1 hour away.<br><br><span class="merci-scenario-label">Caution</span><br>Use <span class="merci-kw-mark">glucagon (IM/SC) or IV dextrose 50%</span> only when the client is unconscious, seizing, or NPO. Avoid chocolate, ice cream, or peanut butter for acute correction because fat slows absorption.

Key concepts

• Hypoglycemia — Blood glucose <70 mg/dL with neuroglycopenic symptoms (confusion, dizziness, headache) and/or adrenergic symptoms (tremor, sweating, tachycardia, palpitations). Severe hypoglycemia involves altered consciousness or inability to self-treat and requires parenteral therapy.
• Rule of 15 — ADA-recommended sequence for treating conscious mild-to-moderate hypoglycemia: 15 g of fast-acting oral carbohydrate -> recheck blood glucose in 15 minutes -> repeat if still <70 mg/dL. Used in adults who are alert and able to swallow.
• Glucagon — A pancreatic alpha-cell hormone given IM or SC (1 mg) for severe hypoglycemia when the client cannot take oral intake. Mobilizes hepatic glycogen to raise blood glucose. Common adverse effects include nausea and vomiting; place the client in a lateral recovery position.
