1. The following medication order is in the patient’s medication administration record (MAR):
n n n n n n n n n n n
methylPREDnisolone 40 mg PO daily at 0900. n n n n n n
After reading the order, the nurse correctly determines:

Feedback
A drug label with a boxed warning provides information to healthcare
