A magnetic resonance imaging (MRI) scan is prescribed for a client with a suspected brain tumor. Which prescription should the nurse anticipate will be prescribed for the client before the procedure?
Correct answer
B
Rationale
An MRI scan is a noninvasive diagnostic test that visualizes the body's tissues, structure, and blood flow. For an MRI, the client is positioned on a padded table and moved into a cylinder-shaped scanner. Relaxation techniques, an eye mask, and sedation are used before the procedure to reduce claustrophobic effects; however, because the client must remain very still during the scan, the nurse avoids oversedating the client to ensure client cooperation. There is no useful purpose for administering an opioid, corticosteroid, or antihistamine.
