The nurse completes a screening questionnaire with a client scheduled for a magnetic resonance imaging (MRI) exam. Which assessment finding most concerns the nurse?
1. Wears a hearing aid.
2. Has body piercings.
3. Reports claustrophobia.
4. Has an aneurysm clip.
The correct answer and explanation is:
The correct answer is 4. Has an aneurysm clip.
Magnetic resonance imaging (MRI) uses powerful magnets to produce detailed images of the inside of the body. The magnetic field can interact with metal objects, leading to potential safety hazards during the scan. Aneurysm clips, typically made of metal, pose a significant risk during an MRI because they can move or heat up in response to the magnetic field, which may cause injury to the client or interfere with the accuracy of the MRI.
An aneurysm clip is used to treat brain aneurysms by sealing the aneurysm and preventing it from rupturing. If a patient has an aneurysm clip, it is essential to determine whether the clip is MRI-compatible. If it is not, the MRI may not be performed safely. The risk of clip movement or heating could lead to serious complications such as brain injury or rupture of the aneurysm. This is why the nurse must be especially cautious and confirm the type of aneurysm clip before proceeding with the MRI.
The other findings, though important, do not pose as significant a risk in relation to MRI safety. Wearing a hearing aid (option 1) and having body piercings (option 2) may require adjustments or removal of these items before the scan to avoid interference with the MRI machine or slight heating, but they do not pose the immediate life-threatening risk that an aneurysm clip does. Claustrophobia (option 3) is a common concern for MRI patients, but it can often be managed with techniques such as sedation or providing the patient with a mirror or open MRI options. However, this does not create an immediate risk to the patient’s physical safety.
