Q&A | Walden University
1. Which of the following best describes the primary purpose of a black box warning
on a prescription medication?
A) To indicate the drug is available over the counter
B) To provide dosing instructions for pediatric patients
C) To highlight serious or life-threatening risks associated with the drug
D) To indicate the drug is contraindicated in all patients
Correct Answer: To highlight serious or life-threatening risks associated with the
drug
Rationale: A black box warning is the strongest safety warning required by the FDA,
highlighting serious or life-threatening adverse effects. It does not mean the drug is
contraindicated in all patients but requires careful consideration of risks and benefits.
It is not related to over-the-counter availability or pediatric dosing.
2. What is the primary role of a nurse during phase III clinical trials of an
investigational drug?
A) Consulting on the choice of testing methodology
B) Administering the investigational drug to patients and monitoring for effects
C) Determining the final efficacy and safety of the drug
D) Recruiting healthy volunteers for the initial safety studies
,Correct Answer: Administering the investigational drug to patients and monitoring
for effects
Rationale: Nurses are generally most involved in phase III clinical trials, where they
may administer the investigational drug to patients and monitor for therapeutic and
adverse effects. The final determination of efficacy and safety is beyond the nurse's
scope, and consulting on testing methodology is not a routine nursing role.
Recruiting healthy volunteers is typically part of phase I trials.
3. According to the principles of pharmacogenomics, what primarily accounts for
unique individual responses to drugs?
A) The patient's age and weight
B) The patient's genetic makeup
C) The route of drug administration
D) The cost of the medication
Correct Answer: The patient's genetic makeup
Rationale: Pharmacogenomics is the study of how genetic variations influence
individual responses to drugs. It explores unique differences based on the mapping
of the human genome, allowing for personalized drug regimens. Age, weight, route
of administration, and cost are important factors but are not the primary focus of
pharmacogenomics.
4. A nurse practitioner is prescribing a medication to a patient of Chinese descent.
What pharmacokinetic factor should the nurse consider?
A) Chinese patients typically require higher doses of all medications
B) Chinese patients may have a greater number of lithium-activated receptors
, C) Chinese patients metabolize all drugs faster than other groups
D) Chinese patients are immune to most drug side effects
Correct Answer: Chinese patients may have a greater number of lithium-activated
receptors
Rationale: Research indicates that Chinese patients may have a greater number of
lithium-activated receptors, often requiring lower-than-normal doses of lithium. This
is an example of how genetic variations affect drug response. It is not accurate to
make broad generalizations about all medications or metabolism rates for any
population.
5. What is the primary purpose of a medication administration record (MAR)?
A) To document the cost of each medication
B) To serve as a legal record of medication administration
C) To replace the need for physician orders
D) To track the patient's dietary intake
Correct Answer: To serve as a legal record of medication administration
Rationale: The MAR is a legal document that records the administration of
medications, including the dose, route, time, and patient response. It does not
replace physician orders, track dietary intake, or primarily document costs. Accurate
documentation on the MAR is essential for patient safety and legal accountability.
6. A nurse is reviewing a medication order that reads: "Amoxicillin 250 mg every 8
hours." What critical piece of information is missing from this order?
