A nurse prepares a client for prescribed magnetic resonance imaging (MRI). Which action should the nurse implement prior to the test?
a. Implement nothing by mouth (NPO) status for 8 hours.
b. Withhold all daily medications until after the examination.
c. Administer morphine sulfate to prevent claustrophobia during the test.
d. Place the client in a gown that has cloth ties instead of metal snaps.
ANS: D
Metal objects are a hazard because of the magnetic field used in the MRI procedure. Morphine sulfate is not administered to prevent claustrophobia; lorazepam (Ativan) or diazepam (Valium) may be used instead. The client does not need to be NPO, and daily medications do not need to be withheld prior to MRI.
