What condition is a contraindication for magnetic resonance imaging (MRI) that the nurse should check in a client's medical history?

• A. Pacemaker insertion
• B. Metallic implants
• C. Pregnancy
• D. Obesity

Answer: (A)

The presence of a pacemaker is a critical contraindication for magnetic resonance imaging (MRI) due to the magnetic fields generated during the procedure. Pacemakers are composed of metallic components that can malfunction or move when exposed to the strong magnetic forces of an MRI machine, which can pose significant risks to the patient, potentially resulting in life-threatening arrhythmias or complete failure of the pacemaker. Therefore, it is essential for healthcare professionals to thoroughly review a client’s medical history for any inserted pacemakers before proceeding with an MRI. While other options like metallic implants are also important to consider, many modern implants are now designed to be MRI-safe or compatible, requiring additional checks for specific types. Pregnancy, while important to assess due to potential risks, is not an absolute contraindication for all MRIs, but it requires careful consideration of the risks versus benefits. Obesity is primarily related to the physical constraints of fitting into the MRI machine rather than a direct contraindication, as long as the patient does not have any other conditions that would be adversely affected by the MRI. Therefore, checking for a pacemaker is a crucial aspect of patient safety when considering MRI procedures.
