## Question

The nurse is preparing care for a client with a central venous catheter. Which actions help reduce central line infection risk? Select all that apply.

1

Change an intact transparent dressing every shift.

2

Use sterile technique during dressing changes.

3

Keep the line in place after it is no longer needed for convenience.

4

Perform hand hygiene before accessing the line.

5

Scrub the needleless connector before use.

6

Assess daily whether the central line is still necessary.

## Explanation

Central line infection prevention includes hand hygiene, disinfecting access ports, sterile dressing changes, and daily review of line necessity. Intact transparent dressings are not changed every shift unless soiled, loose, or due by policy. Unnecessary lines should be removed to reduce infection risk.

## In-depth explanation

Clinical Judgment
Prevent bloodstream infection by protecting every line access and removing unnecessary device days.

Memory Tip
Clean hands, scrub hub, sterile dressing, remove when not needed.

KR vs US
NCLEX device questions reward bundle thinking rather than one isolated task.

## Clinical scenario

Clinical Practice Guide
CDC Standard Precautions emphasize hand hygiene, and central line bundles emphasize asepsis, hub disinfection, dressing integrity, and prompt removal when no longer necessary.

Caution
Every access is a potential contamination event.

## Key concepts

- **Central Line** — A venous catheter with a tip in a central vein, used for selected medications, fluids, nutrition, or monitoring.
- **Aseptic Technique** — Practices that reduce contamination of sterile or clean equipment and sites.
- **Hub Disinfection** — Cleaning the line connector before access to reduce microbial entry.
