methylPREDnisolone 40 mg PO daily at 0900.
After reading the order, the nurse correctly determines:
A “PO” is an inappropriate abbreviation.
B the medication order is written correctly.
C 40 mg should be written as 40mg.
D tall man lettering indicates that the drug is a narcotic.
ANSWER: B
Feedback
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.
2. Which of the following accurately describes the “Boxed Warning” found on a drug label?
A It is primarily is used to identify the safe dose for the patient.
B It is commonly found on all drug labels.
C It identifies serious potential risks and side effects related to drug use.
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.
The warning is found on specific prescription medications and does not
provideinformation to reduce or decrease side effects.
3. When practicing safety in the administration of medication, for which of the
followingmedication 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.
D Ondansetron 4 mg IVP stat.
