Hypoglycemia Refusal & Capacity
Objective: After dextrose or oral glucose, decide who can refuse. Waking up is not enough. They need to be oriented, able to eat, not on a long-acting pill that pushes the pancreas to release insulin, and allowed to refuse under your protocol.
Why this matters
They wake up irritable and want you gone. Waking up is not enough to refuse. Teaching treats symptomatic glucose under 70 mg/dL as low sugar. A refusal after treatment is a capacity decision, plus the risk that the sugar will fall again. Do not take a signature and leave.
- Recheck the sugar and orientation after treatment. Do not decide from the first wake-up.
- Ask the actual medicine. Insulin is not the same as a sulfonylurea, a pill that pushes the pancreas to release insulin. Those long-acting pills can drop the sugar again.
- They need food they can swallow. If they will not eat, transport them.
Clinical sequence
- Recheck the sugar and orientation after treatment. Slurred speech is not capacity yet. Do not accept a refusal while they are still slurring.
- Ask whether the medicine is insulin or a sulfonylurea such as glyburide or glipizide. Long-acting pills can cause another drop.
- Make a food plan they can actually swallow. If they will not eat, transport them.
- Higher-risk refusals include a sulfonylurea, alcohol, living alone, or no responsible adult. Use online medical control when the protocol says so. Document the warning you gave.
Teaching points
- Capacity is more than waking up. They are oriented. They understand the risk of dropping again. They are not still intoxicated, and they are not still waking from a seizure.
- Higher-risk refusals. Sulfonylurea pills, long-acting insulin, alcohol, no responsible adult, no food, and an older adult who lives alone.
- Online medical control exists for this. Use it when the protocol says so. Do not skip it when the protocol requires it.
- Write it down. Record the sugar before and after, what they ate, who is with them, and the warning you gave.
Common errors
- Taking a refusal while they are not fully awake, such as a GCS of 13.
- Leaving with no food plan.
- Skipping the medication list.
Practice
One-minute check
Two patients. (1) A young insulin user who ate a sandwich, GCS 15, roommate home. (2) An older adult on glyburide who lives alone and wants you gone. Who should be transported?
