NURS 5334 ADVANCED PHARMACOLOGY FINAL EXAM 2026/2027
PRACTICE QUESTIONS AND STUDY GUIDE ACCURATE EXAM COMPLETE
ACTUAL QUESTIONS AND CORRECT VERIFIED ANSWERS WITH DETAILED
RATIONALES
1. A 68-year-old patient with hypertension, chronic kidney disease, and type 2
diabetes is being started on a new medication. The PMHNP/NP wants to
minimize adverse effects while accounting for age-related reductions in
renal clearance. Which pharmacologic principle should guide the initial
prescribing approach?
A. Use the maximum recommended dose to achieve rapid therapeutic
effect
B. Start with a lower dose and titrate according to therapeutic response,
renal function, and adverse effects
C. Avoid all medications that undergo renal elimination
D. Use the same dose in older adults regardless of kidney function
Answer: B
2. A patient asks the advanced practice nurse to explain the difference
between pharmacokinetics and pharmacodynamics before starting a new
medication. Which explanation is most accurate?
A. Pharmacokinetics describes what the drug does to receptors, whereas
pharmacodynamics describes drug excretion
B. Pharmacokinetics describes adverse effects only, whereas
pharmacodynamics describes absorption
C. Pharmacokinetics describes absorption, distribution, metabolism, and
excretion, whereas pharmacodynamics describes the drug's effects and
mechanisms of action
D. Pharmacokinetics and pharmacodynamics are interchangeable terms
Answer: C
3. A medication is administered orally and undergoes extensive metabolism in
the liver before reaching systemic circulation. The patient requires a
substantially larger oral dose than an equivalent parenteral dose. Which
pg. 1
, pharmacokinetic concept best explains this difference?
A. First-pass metabolism
B. Protein binding
C. Renal tubular secretion
D. Volume of distribution
Answer: A
4. A patient receives a medication with a half-life of 12 hours. The nurse
practitioner explains that repeated dosing will gradually produce
accumulation until a stable concentration is achieved. Approximately how
long does it generally take to approach steady state with regular dosing?
A. 12 hours
B. 24 hours
C. 36 hours
D. 48–60 hours
Answer: D
5. A highly lipid-soluble medication is administered to an adult with a large
amount of adipose tissue. Compared with a water-soluble medication,
which pharmacokinetic characteristic is most likely?
A. Lower distribution into tissues
B. Greater distribution into fatty tissues and potentially prolonged
elimination
C. Complete elimination through the gastrointestinal tract
D. No change in duration of action
Answer: B
6. A patient taking a medication that is highly bound to plasma albumin
develops severe hypoalbuminemia. Which pharmacologic consequence
should the advanced practice nurse anticipate?
A. A possible increase in the unbound fraction of the medication
B. Complete elimination of the medication
C. Decreased absorption from the gastrointestinal tract in every case
pg. 2
, D. Guaranteed therapeutic failure
Answer: A
7. A medication has a narrow therapeutic index, and the patient develops
symptoms suggesting toxicity despite a serum concentration near the upper
end of the therapeutic range. Which principle should guide management?
A. Serum concentrations are never clinically useful
B. The medication should automatically be doubled
C. Close monitoring is important because relatively small concentration
changes may produce toxicity
D. Narrow therapeutic index medications do not require laboratory
monitoring
Answer: C
8. A patient taking a medication metabolized primarily by CYP3A4 begins
another medication that strongly inhibits CYP3A4. Which outcome is most
likely?
A. Increased metabolism and lower drug concentrations
B. No change in medication exposure
C. Immediate renal elimination of the medication
D. Reduced metabolism with potentially increased drug concentrations
Answer: D
9. A patient begins a strong CYP450 enzyme inducer while taking a medication
primarily metabolized through the induced pathway. Which
pharmacokinetic effect is most likely?
A. Increased metabolism and potentially reduced plasma concentration of
the affected medication
B. Complete prevention of metabolism
C. Increased bioavailability of every medication
D. Immediate increase in renal filtration
Answer: A
10. A patient with significant hepatic impairment requires treatment with a
medication extensively metabolized by the liver. Which prescribing
pg. 3
, consideration is most appropriate?
A. Hepatic function is irrelevant to medication dosing
B. The medication should always be given at the maximum dose
C. Dose selection may require adjustment because impaired hepatic
metabolism can increase drug exposure
D. Liver disease always increases renal clearance
Answer: C
11. An older adult is prescribed several medications and reports dizziness,
confusion, constipation, and urinary retention. Which prescribing principle
should the advanced practice nurse emphasize?
A. Add another medication to treat every symptom separately
B. Review the complete medication regimen for cumulative adverse effects
and potentially inappropriate medications
C. Assume all symptoms are caused by dementia
D. Increase the doses of all current medications
Answer: B
12. A medication has a high volume of distribution. Which statement best
describes this pharmacokinetic property?
A. The drug remains almost entirely within the bloodstream
B. The drug is rapidly eliminated by the kidneys
C. The medication cannot cross cell membranes
D. A substantial amount of the medication is distributed into tissues outside
the plasma
Answer: D
13. A patient taking a medication with a long half-life misses one dose and asks
whether an additional dose should automatically be taken. Which response
is most appropriate?
A. Take multiple doses immediately to compensate
B. Double every subsequent dose
C. Follow the medication-specific missed-dose instructions rather than
automatically doubling the next dose
