## Question

Which action helps reduce central line-associated bloodstream infection risk when administering IV medication?

## Option

1. Use the same tubing set indefinitely if it still flushes.
2. Disconnect the line between doses to let the catheter rest.
3. Skip hand hygiene if gloves will be worn.
4. Scrub the catheter hub with antiseptic before access. **✔ Correct answer**

**Correct answer: 4**

## Explanation

Hub disinfection before access reduces the risk of introducing organisms into the central line. Hand hygiene remains necessary even when gloves are worn. Unnecessary disconnection and indefinite tubing use can increase infection risk.

## In-depth explanation

Clinical Judgment
Use the client cues, timing, labs, and safety risks to select the response that best fits Central line hub disinfection.

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 Central line hub disinfection, 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

- **Central Line** — An IV catheter with the tip in a central vein.
- **CLABSI** — Central line-associated bloodstream infection.
- **Hub Disinfection** — Cleaning the catheter access point before use.
