## Question

A client has an indwelling urinary catheter. Which nursing action helps reduce catheter-associated infection risk?

## Option

1. Disconnect the drainage tubing daily to empty retained urine.
2. Raise the drainage bag above bladder level during transport.
3. Irrigate the catheter every shift without a prescription.
4. Keep the drainage system closed and the bag below bladder level. **✔ Correct answer**

**Correct answer: 4**

## Explanation

A closed drainage system and keeping the bag below bladder level reduce contamination and backflow. Disconnecting the tubing and raising the bag above the bladder increase infection risk. Routine irrigation is not performed without an indication and prescription or protocol.

## In-depth explanation

Clinical Judgment
Use the client cues, timing, labs, and safety risks to select the response that best fits Indwelling urinary catheter care.

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 Indwelling urinary catheter care, 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

- **Indwelling Urinary Catheter** — A tube left in the bladder to drain urine continuously.
- **Closed Drainage System** — A catheter system kept sealed to reduce contamination.
- **Backflow** — Reverse movement of urine that can carry organisms toward the bladder.
