## Question

A client is prescribed insulin glargine each evening. Which statement indicates correct understanding of this medication?

## Option

1. I will mix this insulin with my rapid-acting insulin in one syringe.
2. I will use this insulin only when my blood glucose is high.
3. This insulin provides long-acting basal coverage. **✔ Correct answer**
4. This insulin should be taken after meals to cover carbohydrates.

**Correct answer: 3**

## Explanation

Insulin glargine is a long-acting basal insulin and is not mixed with other insulins in the same syringe. It is scheduled rather than used only for correction. Rapid-acting insulin, not glargine, is used to cover meals.

## In-depth explanation

Clinical Judgment
Use the client cues, timing, labs, and safety risks to select the response that best fits Insulin glargine teaching.

Memory Tip
Match the strongest cue cluster to the safest nursing judgment.

KR vs US
NCLEX items reward cue-based priority thinking rather than isolated recall.

## Clinical scenario

Clinical Practice Guide
For Insulin glargine teaching, compare the complete cue pattern with the client's current stability, ordered data, and expected nursing scope.

Caution
Do not choose an action from one isolated cue when the full scenario changes priority or safety.

## Key concepts

- **Insulin Glargine** — A long-acting insulin used for basal glucose control.
- **Basal Insulin** — Insulin that provides background coverage between meals and overnight.
- **Rapid-Acting Insulin** — Insulin used near meals or for correction depending on the prescription.
