MULTIPLE CHOICE yv
1. The following medication order is in the patient’s medication administration record (MAR):
yv yv yv yv yv yv yv yv yv yv yv
methylPREDnisolone 40 mg PO daily at 0900. yv yv yv yv yv yv
After reading the order, the nurse correctly determines:
yv yv yv yv yv yv yv
A “PO” is an inappropriate abbreviation. yv yv yv yv
B the medication order is written correctly.
yv yv yv yv yv
C 40 mg should be written as 40mg. yv yv yv yv yv yv
D tall man lettering indicates that the drug is a narcotic.
yv yv yv yv yv yv yv yv yv yv
ANS: B yv
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.
2. Which of the following accurately describes the “Boxed Warning” found on a drug label?
yv yv yv yv yv yv yv yv yv yv yv yv yv
A It is primarily is used to identify the safe dose for the patient.
yv yv yv yv yv yv yv yv yv yv yv yv
B It is commonly found on all drug labels.
yv yv yv yv yv yv yv
C It identifies serious potential risks and side effects related to drug use.
yv yv yv yv yv yv yv yv yv yv yv
D It protects the patient by providing information to decrease side effects.
yv yv yv yv yv yv yv yv yv yv yv
ANS: C yv
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.
3. When practicing safety in the administration of medication, for which of the following
yv yv yv yv yv yv yv yv yv yv yv yv yv
medication orders should a nurse seek clarification before the administration of the m

ANS: A yv
Feedback
The “u” should never be used in a medication order; rather, for safety, the word
“units” should be spelled out. The other answer options contain the required
components needed to safely carry out the medication order.
4. A nurse is reviewing a drug label with a drug name written with tall man lettering. Which s
yv yv yv yv yv yv yv yv yv yv yv yv yv yv yv yv yv
tatements shows the nurse has a correct understanding of tall man lettering on a drug label?
yv yv yv yv yv yv yv yv yv yv yv yv yv yv yv
A “The tall man lettering means this is a high alert drug.”
yv yv yv yv yv yv yv yv yv yv
B “The tall man lettering helps me distinguish this drug with other drugs that
yv yv yv yv yv yv yv yv yv yv yv yv yv
have similar names.” yv yv
C “The tall man lettering means that this drug must have a Boxed Warning.”
yv yv yv yv yv yv yv yv yv yv yv yv
D “The tall man lettering helps me quickly identify that this drug is an injectable
yv yv yv yv yv yv yv yv yv yv yv yv yv yv
drug.”
ANS: B yv
Feedback
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.
5. The following medication orders are found in the patient’s MAR:
yv yv yv yv yv yv yv yv yv
Metformin HCl 500 mg PO daily at 0900. Hydrochlorothiazid
