A drug label with a boxed warning provides information to healthcare professionals and patients
regarding the serious risks and side effects related to the drug. The Boxed Warning is not the
primary source for identifying the patient’s drug dosage.
The warning is found on specific prescription medications and does not provide information to
reduce or decrease side effects.

medication orders should a nurse seek clarification before the administration of the medication?
A Regular insulin 5 u subcut now.
