## Question

The nurse is preparing to administer a prescribed subcutaneous insulin lispro dose. The meal tray is unexpectedly delayed. Which action should the nurse take?

## Option

1. Administer lispro now and ask the client to wait quietly for the meal
2. Hold lispro until the meal is available and coordinate administration with eating **✔ Correct answer**
3. Substitute the same dose of insulin glargine and administer it at the scheduled time
4. Dilute lispro in IV fluid and infuse it slowly until the meal tray arrives

**Correct answer: 2**

## Explanation

Insulin lispro acts rapidly and should be coordinated closely with food. If the meal is not available, hold the dose and resolve the delay to reduce hypoglycemia risk rather than administering early or substituting another insulin.

## In-depth explanation

Quick answer
Hold insulin lispro until the meal is available, then coordinate the dose with eating. Giving rapid-acting insulin without dependable carbohydrate intake can produce preventable hypoglycemia.

Why this is correct
Lispro begins lowering glucose quickly. Its benefit and safety depend on matching insulin action with absorbed carbohydrate, so an unexpected meal delay changes the immediate administration conditions even though the prescription itself has not changed.

Easy analogy or mental picture
Rapid-acting insulin is like sending a shuttle to meet an arriving train. If the train is delayed, sending the shuttle early leaves it with nothing to meet; the analogy does not replace glucose checks or individualized correction instructions.

Memory hook
Rapid insulin needs ready food: no tray, no routine premeal dose yet.

NCLEX decision rule
Before giving rapid-acting mealtime insulin, verify that the client can eat and that food is available. If intake is delayed or uncertain, hold and clarify timing while monitoring glucose according to the care plan.

Why the other choices are wrong
Giving lispro before food increases hypoglycemia risk. Glargine is not an interchangeable substitute for a mealtime dose, and adding subcutaneous lispro to IV fluid changes the prescribed route and administration method.References
