Hypoglycemia Management With Nausea and IV Access
A 56-year-old with type 1 diabetes is alert but nauseated and shaky. Capillary glucose is 54 mg/dL. The patient received his usual subcutaneous insulin glargine and rapid-acting insulin 40 minutes ago but ate only half of breakfast because of nausea. He has a patent 20-gauge IV in the left forearm. The standing order says: 'If glucose is below 70 mg/dL and patient can swallow safely, give 15 g fast-acting carbohydrate and recheck in 15 minutes. If unable to swallow or IV access is available and patient is symptomatic, give dextrose 50% 25 mL IV push and recheck in 15 minutes. Notify provider if glucose remains below 70 mg/dL after two treatments.' The patient has no history of aspiration and his gag reflex is intact, but he says he feels too sick to drink. He is diaphoretic and his hand tremor makes it hard for him to hold a cup.
1. Which route of glucose should the nurse choose, and why? Use the standing order and the assessment data.

The patient is symptomatic with glucose 54 mg/dL, so treatment is indicated. The order gives oral carbohydrate only if the patient can swallow safely. Although the gag reflex is intact and he is alert, he says he feels too sick to drink and has a hand tremor that makes holding a cup difficult. That makes oral intake unreliable and raises aspiration risk if he vomits. The order also permits IV dextrose when the patient is symptomatic and IV access is available. He has a patent 20-gauge IV. Therefore, give dextrose 50% 25 mL IV push per the standing order, recheck glucose in 15 minutes, and monitor for improvement. The nurse should not force oral juice just because the gag reflex is present; the clinical assessment supports the IV route.
2. After the first treatment, the glucose is 62 mg/dL at 15 minutes. What should the nurse do next, and when should the provider be notified?

At 15 minutes the glucose is 62 mg/dL, still below 70 mg/dL. The patient remains symptomatic or at least has not normalized, so the nurse should give a second treatment per the order: another dextrose 50% 25 mL IV push, because IV access is available and the patient is symptomatic. Recheck glucose in another 15 minutes. If it is still below 70 mg/dL after this second treatment, the order requires provider notification. The nurse should also investigate why the glucose is not rising: the rapid-acting insulin was given 40 minutes ago and the meal was half eaten, so more carbohydrate or a change in the insulin plan may be needed. Continue close monitoring and document each treatment and recheck.
3. Why could giving oral carbohydrate despite nausea be unsafe, and what should the nurse document?
Read the worked answer
Oral carbohydrate could be unsafe because nausea increases the risk of vomiting and aspiration, and a trembling hand makes self-feeding unreliable. Even with an intact gag reflex, 'can swallow safely' is a clinical judgment, not just a reflex check. If the patient vomits, the dose is lost and the airway is at risk. The nurse should document the patient's statement that he feels too sick to drink, the hand tremor, the diaphoresis, the glucose values, the route and dose of dextrose given, the recheck times and values, and the provider notification if required. Documentation should avoid labeling the patient 'noncompliant' and should instead record the assessment and the rationale for choosing IV therapy under the standing order.
