After reading the order, the nurse correctly determines:
A “po” is an inappropriate abbreviation.

used to distinguish the drug from another drug

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.
3. When practicing safety in the administration of medication, for which of the following
medication orders should a nurse seek clarification before the administration of the
medication?
A regular insulin 5 u subcut now.
B enoxaparin 80 mg subcut every 12 hours.
C benadryl 50 mg po prn every 6 hr for itching.
