## Question

Classify each parenteral-nutrition administration action by the safety decision it supports.

|  | Appropriate administration practice | Stop and obtain pharmacy review | Unsafe practice |
| --- | --- | --- | --- |
| Use the prescribed 1.2-micron in-line filter for the PN and lipid emulsion |  |  |  |
| Reserve a dedicated central-line lumen when feasible |  |  |  |
| Bypass an occluded filter so the infusion finishes on time |  |  |  |
| Add an unverified medication to the PN bag at the bedside |  |  |  |
| Stop the infusion and contact pharmacy when the filter repeatedly occludes |  |  |  |
| Verify compatibility before any unavoidable shared-lumen administration |  |  |  |

## Explanation

Parenteral nutrition requires a dedicated line or lumen when possible, the appropriate in-line filter, protected admixture integrity, and pharmacy review of compatibility or filter occlusion. An occluded filter is not bypassed.

## In-depth explanation

Quick answer
Protect the admixture, lumen, filter, and compatibility chain.

Why this is correct
Particles, precipitates, incompatible medications, microbial contamination, and an improvised bypass can reach the circulation directly through central access.

Easy analogy or mental picture
Treat every infusion as a controlled clinical system: verify the product and access, recognize a changing cue, stop preventable exposure, stabilize the client, and confirm the response.

Memory hook
Product, access, compatibility, infusion cue, protective action, and reassessment.

NCLEX decision rule
Choose the action that prevents the most immediate infusion-related harm while preserving vascular access and the ordered diagnostic evidence.

Why the other choices are wrong
Options that restart a suspect product, bypass a safety device, force an occluded tube, or delay reassessment can convert a reversible warning into serious harm.References

## Clinical scenario

Blood product, nutrition, and intravenous-fluid safety review
Verify the product, prescription, route, access device, filter or tubing, compatibility, baseline findings, emerging adverse cues, response plan, and measurable follow-up.
