A nurse is preparing a patient for a magnetic resonance imaging (MRI) scan of the brain. It is crucial for the nurse to ensure the patient understands the pre-procedure requirements. One aspect includes assessing for any contraindications to the procedure. The nurse must check for metallic implants or devices that may pose a risk during the MRI. Before administering the test, the nurse should confirm that the patient has been informed about the need to remain still during the procedure to ensure accurate results. A key element of patient preparation is explaining that they might be asked to wear a gown and to remove any items like jewelry and watches that could interfere with the imaging.
To further ensure patient safety, the nurse should remind the patient that if they experience any anxiety or fear about the enclosed space of the MRI machine, they should inform the staff.
