A client is admitted for an MRI. The nurse should question the client regarding:
A. Pregnancy
B. A titanium hip replacement
C. Allergies to antibiotics
D. Inability to move his feet
Correct Answer: A. Pregnancy
Although there is no evidence to suggest MRI scans can pose a risk during pregnancy, it is considered precaution to not perform MRI during pregnancy, particularly in the first three months. This is particularly the case during the first trimester of pregnancy, as organogenesis takes place during this period. The concerns in pregnancy are the same as for MRI in general, but the fetus may be more sensitive to the effects—particularly to heating and to noise.
Option B: Clients with a titanium hip replacement can have an MRI. Some other devices and implants might be contraindicated. To ensure patients’ safety, the radiologist and MRI technologist must evaluate the type of device that patients have. Radiologists, referring physicians and MR technologists, need to be able to assess MRI safety, patients’ condition, and compatibility of medical devices to keep patients safe.
Option C: No antibiotics are used with this test. MRI contrast agents are gadolinium chelates with different stability, viscosity, and osmolality. Gadolinium is a relatively very safe contrast; however, it rarely might cause allergic reactions in patients.
Option D: The client should remain still only when instructed. Patients who are unable to be still or obey breathing instructions in the scanner need special attention. Some patients in pain might move during the procedure, which degrades the quality of the images, restrict the interpretation, and decrease the accuracy of the report. Some MRI sequences need to be obtained while patients hold their breath and lie motionless.
