,NU 636 Final Exam Advanced Pharmacology Questions And Answers
2026/2027 Herzing University
NU 636 Final Exam — Advanced Pharmacology | Herzing University
Q1. Which statement best describes pharmacodynamics?
A) The body's absorption and elimination of a medication
B) The amount of medication excreted by the kidneys
C) The effects of a medication on the body and its mechanism of action
D) The time required to reach steady state
Correct Answer: C) The effects of a medication on the body and its
mechanism of action
Rationale: Pharmacodynamics describes receptor interactions, dose-
response relationships, and the physiologic effects produced by medications.
Q2. Which medication requires especially close monitoring because
it has a narrow therapeutic index?
A) Topical moisturizer
B) Normal saline nasal spray
C) Digoxin
D) Topical zinc oxide
Correct Answer: C) Digoxin
Rationale: Small changes in digoxin concentration can produce loss of
therapeutic effect or clinically important toxicity.
Q3. Bioavailability refers to:
A) The fraction of an administered dose that reaches systemic circulation
B) The strength with which a drug binds its receptor
C) The maximum response a medication can produce
D) The rate of renal filtration
Correct Answer: A) The fraction of an administered dose that reaches
systemic circulation
Rationale: Bioavailability describes how much active medication becomes
available in systemic circulation.
Q4. A medication is eliminated almost entirely by the kidneys.
Which patient factor is most important when determining an
appropriate dose?
A) Hair color
B) Serum cholesterol only
C) Height alone
D) Renal function
, Correct Answer: D) Renal function
Rationale: Reduced kidney function can decrease medication clearance and
increase the risk of accumulation and toxicity.
Q5. What generally occurs when a strong CYP inhibitor is added to
an active medication metabolized through that pathway?
A) The medication is excreted faster
B) Absorption stops
C) Plasma drug concentrations may increase
D) Receptor affinity disappears
Correct Answer: C) Plasma drug concentrations may increase
Rationale: Enzyme inhibition slows metabolism and can increase systemic
exposure to susceptible medications.
Q6. Which statement best describes drug half-life?
A) Time required for a medication to start working
B) Time required for complete excretion
C) Time required for the plasma concentration to decrease by approximately
50%
D) Time between absorption and receptor binding
Correct Answer: C) Time required for the plasma concentration to decrease
by approximately 50%
Rationale: Half-life helps determine dosing intervals, duration of action, and
time required to approach steady state.
Q7. What is the primary purpose of administering a loading dose?
A) Reduce drug absorption
B) Prevent first-pass metabolism
C) Shorten renal clearance
D) Achieve a therapeutic concentration rapidly
Correct Answer: D) Achieve a therapeutic concentration rapidly
Rationale: Loading doses are useful when waiting several half-lives to reach
therapeutic concentrations would be undesirable.
Q8. Which finding is most consistent with an immune-mediated
medication allergy?
A) Constipation after an opioid
B) Urticaria and bronchospasm after drug exposure
C) Diuresis after furosemide
D) Bradycardia after beta blockade
Correct Answer: B) Urticaria and bronchospasm after drug exposure
