The medication order has all the required components (drug name, dose, route,
andfrequency of administration) for a drug order. “PO” is an appropriate
abbreviation;40 mg is written correctly with a space between the dose and the
unit of measurement. Tall man lettering is used to distinguish the drug from
another drug
with a similar name.

A It is primarily is used to identify the safe dose for the patient.
B It is commonly found on all drug labels.

D It protects the patient by providing information to decrease side effects.
ANSWER: C
Feedback
A drug label with a boxed warning provides information to healthcare
professionalsand 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.

provideinformation to reduce or decrease side effects.
