## Question

A client has a prescription for IV potassium chloride replacement. Which nursing action is safe?

## Option

1. Administer potassium chloride by rapid IV push.
2. Give the medication undiluted through a peripheral IV.
3. Use an infusion pump and follow the prescribed dilution and rate. **✔ Correct answer**
4. Stop cardiac monitoring because potassium is a routine electrolyte.

**Correct answer: 3**

## Explanation

IV potassium chloride must be diluted and infused at a controlled rate, commonly using an infusion pump and facility policy. Rapid IV push or undiluted administration can cause fatal dysrhythmias. Monitoring depends on dose, route, and client condition.

## In-depth explanation

Clinical Judgment
Use the client cues, timing, labs, and safety risks to select the response that best fits IV potassium replacement safety.

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 IV potassium replacement safety, 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

- **Potassium Chloride** — An electrolyte replacement medication that can affect cardiac rhythm.
- **Infusion Pump** — A device that controls the rate of IV medication delivery.
- **Dysrhythmia** — An abnormal heart rhythm that may be life-threatening.
