A client with type 1 diabetes reports feeling shaky, sweaty, and confused 45 minutes after receiving regular insulin. Fingerstick glucose is 58 mg/dL and the client is alert enough to swallow. Which action should the nurse take first?

  1. AAdminister IM glucagon immediately
  2. BGive the client's next scheduled dose of long-acting insulin
  3. CAdminister 15 g of a fast-acting carbohydrate such as 4 oz of juice
  4. DCall the primary provider to report the low glucose
Show answer & explanation

Correct answer: C. Administer 15 g of a fast-acting carbohydrate such as 4 oz of juice

For a conscious client with mild-to-moderate hypoglycemia who can swallow safely, the priority is to give 15 g of fast-acting carbohydrate and recheck glucose in 15 minutes (the 'rule of 15'). Glucagon is reserved for unconscious or unable-to-swallow clients.

Why the other options are wrong

  • A. Glucagon IM is reserved for clients who are unconscious or cannot swallow.
  • B. Insulin would further lower glucose and is contraindicated during hypoglycemia.
  • D. Notification can occur after treating the immediate low glucose.

Rule of 15 for Hypoglycemia

For conscious clients with blood glucose <70 mg/dL, give 15 g fast-acting carbohydrate, recheck glucose in 15 minutes, and repeat if still low.

  • 15 g carb = 4 oz juice, 3-4 glucose tablets, or 1 tbsp honey
  • Recheck glucose 15 min after treatment
  • Glucagon IM/IN reserved for unconscious clients

Memory trick: '15-15-15': 15 g carb, wait 15 min, check again
