## Question

A nurse is implementing the central-line bundle to prevent CLABSI. Which set of practices reflects current evidence-based standards?

## Option

1. Hand hygiene, maximal sterile barrier precautions, chlorhexidine skin antisepsis, avoid femoral site when possible, and daily review of line necessity with prompt removal **✔ Correct answer**
2. No daily site review
3. Femoral site preferred for ease
4. No barrier precautions for routine lines

**Correct answer: 1**

## Explanation

Correct (2): CLABSI prevention bundle (IHI): hand hygiene, maximal sterile barrier (full body drape + cap/mask/gown/gloves), chlorhexidine skin prep, optimal site selection (subclavian > IJ > femoral), and daily review of line necessity with prompt removal. Also chlorhexidine bathing in ICU. (1) Femoral has highest CLABSI risk. (3,4) Required practices.

## In-depth explanation

Memory Tip CLABSI bundle 5 elements = "Hands·Barrier·Chlorhexidine·Site·Daily review". Disinfect hub before each access (scrub the hub × 15 sec, allow to dry).

## Clinical scenario

Scenario ICU placing a new central venous catheter; nurse implementing CLABSI prevention bundle.

## Key concepts

- **CLABSI bundle** — 5-element evidence-based prevention bundle for central-line-associated bloodstream infection.
- **Maximal sterile barrier** — Full body drape, cap, mask, sterile gown and gloves during line insertion.
- **Scrub the hub** — Disinfect catheter hub with alcohol or chlorhexidine swab for ≥15 sec; allow to dry.
