## Question

The nurse teaches a client about insulin glargine. Which statement by the client indicates correct understanding?

## Option

1. I will use it only when my blood glucose is high.
2. "I will store the pen at room temperature once opened, and it should be discarded after 28 days
3. I should expect it to peak strongly 30 minutes after injection.
4. I will take it at the same time each day as my long-acting insulin. **✔ Correct answer**

**Correct answer: 4**

## Explanation

Insulin glargine is a long-acting basal insulin and is taken consistently as prescribed. It is not used only as correction insulin, is not mixed with other insulin in the same syringe, and does not have a strong rapid peak. Consistency helps maintain basal glucose control.

## In-depth explanation

Clinical Judgment
Basal insulin is background coverage, not a quick correction dose.

Memory Tip
Glargine: long, steady, do not mix.

## Clinical scenario

Clinical Practice Guide
Insulin teaching includes type, timing, hypoglycemia signs, injection technique, storage, and glucose monitoring.

Caution
Never assume all insulins can be mixed.

## Key concepts

- **Insulin Glargine** — A long-acting insulin used for basal glucose control.
- **Basal Insulin** — Background insulin coverage between meals and overnight.
- **Hypoglycemia** — Lower-than-normal blood glucose that can cause sweating, shakiness, confusion, or seizures.
