Introduction
The NR566 Week 8 Final Examination assesses the advanced
practice nursing student's competency in pharmacotherapeutic
management across the lifespan for family care. The examination
evaluates knowledge of pharmacokinetic principles, drug
mechanisms, therapeutic monitoring, and individualized
prescribing for diverse patient populations. Questions incorporate
multiple-choice and scenario-based formats requiring clinical
,decision-making and application of pharmacologic principles to
real-world clinical situations. Emphasis is placed on drug
interactions, adverse effect recognition, CYP450 metabolism,
special population considerations, and evidence-based
prescribing for infectious, endocrine, cardiovascular, respiratory,
and neurological conditions. This assessment ensures practitioners
demonstrate the critical thinking skills necessary for safe and
effective pharmacotherapeutics in advanced family practice
nursing.
SECTION ONE: QUESTIONS 1–100
Question 1
A 75-year-old patient is prescribed a new medication that is
primarily renally excreted. Which of the following adjustments is
most appropriate?
A. Increase the dose
B. Decrease the dose or increase the dosing interval
C. No adjustment is needed
D. Administer the medication intravenously
🟢 B. Decrease the dose or increase the dosing interval
🔴 RATIONALE: In older adults, renal function declines with age
(estimated glomerular filtration rate decreases). For medications
primarily renally excreted (e.g., digoxin, lithium, aminoglycosides,
many antibiotics), dose reduction or extended dosing intervals are
required to prevent accumulation and toxicity. Creatinine
clearance should be calculated using the Cockcroft-Gault
equation to guide dosing .
Question 2
,Which of the following pharmacokinetic changes occurs in
pregnancy?
A. Increased gastric emptying time
B. Increased plasma volume leading to increased volume of
distribution
C. Decreased hepatic metabolism
D. Decreased renal blood flow
🟢 B. Increased plasma volume leading to increased volume of
distribution
🔴 RATIONALE: Pregnancy causes significant physiological
changes: increased plasma volume (up to 50%), increased cardiac
output, increased renal blood flow and GFR, and altered hepatic
metabolism. The increased volume of distribution may require
higher doses of some medications to achieve therapeutic levels.
Gastric emptying is often delayed, and hepatic metabolism may
be altered .
Question 3
Which of the following is a key consideration when prescribing
medications to a breastfeeding mother?
A. Most drugs are contraindicated during breastfeeding
B. Drugs with long half-lives are preferred
C. Drugs with high protein binding and low oral bioavailability are
less likely to reach the infant
D. All medications are safe during breastfeeding
🟢 C. Drugs with high protein binding and low oral bioavailability
are less likely to reach the infant
🔴 RATIONALE: Medications that are highly protein-bound
remain primarily in the maternal plasma and are less likely to pass
, into breast milk. Drugs with low oral bioavailability are poorly
absorbed by the infant, reducing systemic exposure. Most drugs
are compatible with breastfeeding, but some are contraindicated
(e.g., radioactive compounds, amiodarone, lithium, cytotoxic
drugs). Short half-life drugs are preferred over long half-life drugs
.
Question 4
Which of the following best describes the "first-pass effect"?
A. The first dose of a medication given to a patient
B. The metabolism of a drug in the liver before it reaches systemic
circulation
C. The binding of a drug to plasma proteins
D. The excretion of a drug through the kidneys
🟢 B. The metabolism of a drug in the liver before it reaches
systemic circulation
🔴 RATIONALE: The first-pass effect (first-pass metabolism) is the
metabolism of a drug in the liver (and sometimes intestinal wall)
after oral administration before it reaches systemic circulation.
Drugs with high first-pass metabolism have reduced
bioavailability and may require higher oral doses or alternative
routes (sublingual, IV) to achieve therapeutic effects .
Question 5
A patient has cirrhosis of the liver. Which of the following
medications would require dose adjustment due to altered
metabolism?
A. Heparin
B. Warfarin
