The statements by the client that would require the nurse to notify the health care provider to cancel the MRI procedure are: 

● “I had a pacemaker inserted a few years ago because my heart was not beating fast enough.” 

● "I fell down my basement steps last year and broke my hip and had to have a hip replacement.” 

● “When I was diagnosed with mitral valve prolapse, they had to replace the valve with a prosthetic valve." 

These statements indicate that the client has metallic implants or devices in their body, which can be affected by the strong magnetic field of an MRI machine. This can pose a risk to the client’s safety and may interfere with the accuracy of the MRI results. 

The other statements do not necessarily require the cancellation of the MRI procedure, but the nurse may need to take additional precautions or provide additional support to ensure the client’s comfort and safety during the procedure. 

Here is a detailed explanation of why the other choices do not necessarily require the cancellation of the MRI procedure: 

● “I have such terrible anxiety, I don’t know if I can remain still throughout the procedure.”: While anxiety can make it difficult for a client to remain still during an MRI procedure, it does not necessarily require the cancellation of the procedure. The nurse may provide additional support or medication to help the client manage their anxiety and remain still during the procedure. 

● “I have diabetes mellitus type and have been taking insulin for many years.”: Having diabetes and taking insulin does not necessarily require the cancellation of an MRI procedure. The nurse may need to take additional precautions to ensure that the client’s blood sugar levels are stable during the procedure, but it does not pose a direct risk to the client’s safety or interfere with the accuracy of the MRI results.
