A client with type 1 diabetes received the morning insulin dose, and the breakfast tray was delayed. The client is alert, can swallow, and reports shakiness. The point-of-care glucose is 58 mg/dL. Which action should the nurse take next?

Treat conscious hypoglycemia with 15 g of fast-acting carbohydrate, then recheck the glucose after 15 minutes. The recheck confirms recovery before a meal is offered.

Quick answer
Give 15 g of fast-acting carbohydrate and recheck the glucose after 15 minutes.

Why this is correct
A client who is alert and able to swallow is treated by the oral route. The 15 g amount raises the glucose without overshooting, and the 15-minute recheck is the step that proves treatment worked before anything else is added.

Easy analogy or mental picture
The recheck is like reading a thermometer after turning up the heat. Skipping it means acting on hope rather than on a measured value, although the analogy does not imply that another dose is automatic.

Memory hook
15 g, then 15 minutes, then look again.

NCLEX decision rule
For symptomatic hypoglycemia in a client who can swallow, give 15 g of oral carbohydrate and recheck in 15 minutes. Reserve intravenous dextrose for a client who cannot take carbohydrate safely by mouth.

Why the other choices are wrong
Doubling the carbohydrate does not speed recovery and risks rebound hyperglycemia. Serving the meal before the recheck removes the confirmation step. Intravenous dextrose belongs to the client who cannot swallow.
