## Question

The radiology nurse reviews the final MRI safety check. Which findings require immediate follow-up? Highlight the unresolved findings that make scanner-room entry unsafe.

Nurses' Notes
1030: The radiology nurse completes the final safety check before a client enters the MRI scanner room. The wristband and order show that two client identifiers match the scheduled examination. The plan confirms that hearing protection will be worn during image acquisition. The history states that an intracranial aneurysm clip type cannot be verified. No operative record or implant card is available. The client has changed into a facility gown with empty pockets and no metal fasteners. The skin check finds that a transdermal patch with metallic backing remains in place. The patch product has not been cleared for the scanner conditions. The nurse verifies that the infusion pump is MR Conditional under the planned settings. At 1036, the client reports that claustrophobia was discussed and a coping plan was agreed. The client remains able to communicate with staff through the call system. A transporter brings a standard ferromagnetic oxygen cylinder into Zone IV. The nurse stops room entry before the cylinder approaches the magnet. The checklist confirms that the client removed jewelry and detachable hearing aids. Emergency equipment remains outside the restricted room according to the site plan. The examination does not begin until every unresolved hazard receives MR safety review.

## Explanation

An unverified intracranial clip, a metallic-backed transdermal patch, and a ferromagnetic oxygen cylinder in Zone IV require immediate follow-up. Stop entry until each item is identified, removed, or cleared under MR conditions.

## In-depth explanation

Quick answer
Highlight the unverified intracranial clip, the metallic-backed patch, and the ferromagnetic oxygen cylinder entering Zone IV. Each creates an unresolved implant, heating, or projectile hazard before MRI begins.

Why this is correct
The MRI magnet remains powerful even when no image is being acquired. An unverified implant may move or malfunction, metallic material in a patch can heat the skin, and a ferromagnetic cylinder can become a projectile. A full-stop final check keeps the client outside the scanner room until device identity and conditions are verified and unsafe objects are removed.[2]

Easy analogy or mental picture
Picture the MRI room as a strong invisible current. Verified equipment is a boat designed for that current; an unknown implant or loose steel cylinder has unknown behavior and must stay out. The picture explains screening but not a device’s technical conditions.

Memory hook
Unknown implant, metal on skin, loose steel: stop before Zone IV.

NCLEX decision rule
When an implant, wearable product, or equipment label is unknown around MRI, think unresolved magnetic risk; check written device conditions and complete the final screen before allowing Zone IV entry.

Why the other choices are wrong
Matching identifiers, planned hearing protection, metal-free clothing, verified MR Conditional equipment, a claustrophobia plan, and removal of jewelry are protective steps. They do not neutralize a separate unknown implant or ferromagnetic object.References
