Feedback
The medication order has all the required components (drug name, dose, route, and
frequency 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.

Feedback
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.

Tall man lettering highlights a portion of the drug name to help distinguish from
similar drug names. It is not used to identify high alert drugs, highlight a boxed
warning, or identify injectable drugs.
