NCLEX-PN® ExaminationReduction of Risk PotentialMedium
A client is scheduled for a magnetic resonance imaging (MRI) of the brain. Which client statement indicates the need for further nursing assessment and possible intervention?
- AI removed all my jewelry and changed into the gown.
- BI have an artificial pacemaker from my heart surgery years ago.
- CI took my prescribed anti-anxiety medication this morning.
- DI'm a little nervous about being in an enclosed space.
Show answer & explanationAnswer & explanation
Correct answer: B. I have an artificial pacemaker from my heart surgery years ago.
An artificial pacemaker is a contraindication for an MRI due to the strong magnetic field, which can interfere with or damage the device, posing a significant safety risk to the client. This requires immediate intervention and cancellation or modification of the MRI.
Why the other options are wrong
- A. Removing jewelry and changing into a gown are appropriate preparations for an MRI.
- C. Taking anti-anxiety medication is acceptable and often encouraged for claustrophobic clients undergoing an MRI.
- D. Nervousness or claustrophobia is common, but it can often be managed with medication or coping strategies, not an absolute contraindication.
MRI Contraindications
Conditions or implanted devices that make a magnetic resonance imaging (MRI) procedure unsafe or impossible due to the powerful magnetic field.
- Absolute contraindications: pacemakers, certain cochlear implants, cerebral aneurysm clips
- Relative contraindications: some artificial joints, metal fragments in eyes/body, pregnancy
- Safety screening is paramount before MRI
