MULTIPLE CHOICE v




1. The following medication order is in the patient’s medication administration record (MAR):
v v v v v v v v v v v




methylPREDnisolone 40 mg PO daily at 0900. v v v v v v




After reading the order, the nurse correctly determines:
v v v v v v v




A “PO” is an inappropriate abbreviation. v v v v




B the medication order is written correctly. v v v v v




C 40 mg should be written as 40mg. v v v v v v




D tall man lettering indicates that the drug is a narcotic. v v v v v v v v v




ANS: B v




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




frequency of administration) for a drug order. “PO” is an appropriate abbreviation; 40
v v v v v v v v v v v v v




mg is written correctly with a space between the dose and the unit of
v v v v v v v v v v v v v v




measurement. Tall man lettering is used to distinguish the drug from another drug with v v v v v v v v v v v v v




a similar name.
v v v




2. Which of the following accurately describes the “Boxed Warning” found on a drug label?
v v v v v v v v v v v v v




A It is primarily is used to identify the safe dose for the patient.
v v v v v v v v v v v v




B It is commonly found on all drug labels. v v v v v v v




C It identifies serious potential risks and side effects related to drug use.
v v v v v v v v v v v




D It protects the patient by providing information to decrease side effects.
v v v v v v v v v v




ANS: C v




Feedback
A drug label with a boxed warning provides information to healthcare professionals and
v v v v v v v v v v v v




patients regarding the serious risks and side effects related to the drug. The Boxed
v v v v v v v v v v v v v v




Warning is not the primary source for identifying the patient’s drug dosage.
v v v v v v v v v v v v




The warning is found on specific prescription medications and does not provide
v v v v v v v v v v v




information to reduce or decrease side effects.
v v v v v v v




3. When practicing safety in the administration of medication, for which of the following
v v v v v v v v v v v v




medication orders should a nurse seek clarification before the administration of the
v v v v v v v v v v v v




medication?
v




1

, A Regular insulin 5 u subcut now. v v v v v




B Enoxaparin 80 mg subcut every 12 hours. v v v v v v




C Benadryl 50 mg PO PRN every 6 hr for itching. v v v v v v v v v




D Ondansetron 4 mg IVP stat. v v v v




ANS: A v




Feedback
The “u” should never be used in a medication order; rather, for safety, the word
v v v v v v v v v v v v v v




“units” should be spelled out. The other answer options contain the required components
v v v v v v v v v v v v




needed to safely carry out the medication order.
v v v v v v v v




4. A nurse is reviewing a drug label with a drug name written with tall man lettering. Which
v v v v v v v v v v v v v v v v




statements shows the nurse has a correct understanding of tall man lettering on a drug label?
v v v v v v v v v v v v v v v v




A “The tall man lettering means this is a high alert drug.” v v v v v v v v v v




B “The tall man lettering helps me distinguish this drug with other drugs that v v v v v v v v v v v v




have similar names.” v v




C “The tall man lettering means that this drug must have a Boxed Warning.” v v v v v v v v v v v v




D “The tall man lettering helps me quickly identify that this drug is an injectable
v v v v v v v v v v v v v




drug.” v




ANS: B v




Feedback
Tall man lettering highlights a portion of the drug name to help distinguish from
v v v v v v v v v v v v v




similar drug names. It is not used to identifyhigh alert drugs, highlight a boxed warning, or
v v v v v v v v v v v v v v v v




identify injectable drugs.
v v v




5. The following medication orders are found in the patient’s MAR:
v v v v v v v v v




Metformin HCl 500 mg PO daily at 0900. Hydrochlorothiazide v v v v v v v v




25 mg PO every 12 hr at 0900 and 2100. Digoxin .25 mg PO daily
v v v v v v v v v v v v v v v




at 0900.
v v




In reading the medication orders for the 0700–1500 shift, the nurse determines that which of the
v v v v v v v v v v v v v v v




following is the priority nursing intervention?
v v v v v v




A Clarify the metformin HCl order. v v v v




B Clarify the hydrochlorothiazide order. v v v




C Clarify the digoxin order. v v v




D Prepare to administer the 0900 medications. v v v v v




ANS: C v
