NCLEX-PN® ExaminationReduction of Risk PotentialHard
A client is scheduled for a magnetic resonance imaging (MRI) of the knee. Which information obtained by the LPN during the client interview would be most critical to report to the MRI technologist?
- AClient reports claustrophobia in enclosed spaces.
- BClient has a history of seasonal allergies.
- CClient states they are anxious about the loud noises during the scan.
- DClient had surgery to repair a fractured jaw with metal plates 5 years ago.
Show answer & explanationAnswer & explanation
Correct answer: D. Client had surgery to repair a fractured jaw with metal plates 5 years ago.
Metal implants, such as plates, screws, or pacemakers, are contraindications for MRI due to the strong magnetic field. The MRI technologist must be aware of any metal in the client's body to ensure safety and prevent potential injury or artifact interference.
Why the other options are wrong
- A. Claustrophobia is important to address but is not a direct contraindication for the MRI itself; it can be managed with medication or open MRI.
- B. Seasonal allergies are irrelevant to an MRI scan.
- C. Anxiety about noise is common and can be managed with earplugs or sedation, but it is not a safety contraindication.
MRI Contraindications
Conditions or implanted devices that make magnetic resonance imaging (MRI) unsafe or impossible due to the powerful magnetic field and radiofrequency waves.
- Ferromagnetic objects are absolute contraindications.
- Implants like pacemakers, certain clips, and metal fragments are dangerous.
- Pregnancy is a relative contraindication.
