NRG 200 Pharmacology for Human Caring Nursing Final Exam 2026/2027 | Verified Questions
,Introduction
This document contains 100 original, verified questions spanning four core domains:
Pharmacologic Principles and Drug Actions; Medications Affecting Major Body Systems; Special
Populations and Considerations; and Medication Administration, Safety, and Patient Education.
Every question has been written originally for the Academic Year 2026/2027 to reinforce the
official Pharmacology for Human Caring Nursing Final Comprehensive Examination objectives,
supporting actual exam readiness, clinical proficiency, and safe medication administration across
the lifespan. Each item pairs a clinically accurate stem with four options and a concise rationale
grounded in foundational nursing pharmacology textbooks and current clinical guidelines, so the
reasoning behind every correct option is transparent and instructive. Work through each domain
in sequence, record your results on the domain score tracker, and revisit the rationales for any
question you miss before sitting your actual exam.
Actual Questions
Domain 1: Pharmacologic Principles and Drug Actions
Question 1. What does pharmacokinetics describe?
A. What a drug does to the body at receptor sites
B. The cost analysis of drug therapy
C. What the body does to a drug—absorption, distribution, metabolism, and excretion
D. The legal classification of medications
Correct Answer: C
Rationale: Kinetics is the movement story: liberation into absorption, travel through
distribution, transformation by metabolism, and departure through excretion.
Question 2. What does pharmacodynamics study?
A. How the kidney removes a drug
B. What a drug does to the body, including receptor interactions and dose response
C. How drugs are manufactured
D. How prescriptions are transmitted
Correct Answer: B
Rationale: Dynamics is the effect story—drug-receptor binding, dose-response curves, and the
mechanisms of therapeutic and adverse action.
Question 3. A drug with high first-pass metabolism is switched from oral to
sublingual. What is the expected change?
A. Higher bioavailability, because blood from the mouth bypasses the portal circulation
B. Lower bioavailability from gut destruction
C. Identical blood levels by either route
D. Total loss of all drug effect
NRG 200 Pharmacology for Human Caring Nursing Final Exam 2026/2027 | Verified Questions
,Correct Answer: A
Rationale: Sublingual absorption drains to the superior vena cava, skipping hepatic first-pass
extraction—more intact drug reaches the circulation.
Question 4. Why does a loading dose sometimes precede maintenance dosing?
A. To empty the stomach before therapy
B. To double every maintenance dose forever
C. To fill the volume of distribution and reach target concentration without waiting for
accumulation
D. Because all drugs require loading always
Correct Answer: C
Rationale: When tissues must be saturated first, the loading dose fills the tank so the steady-
state tap begins immediately.
Question 5. After five half-lives of consistent dosing, how much of steady state has
been reached?
A. Fifty percent
B. Seventy-five percent
C. One hundred percent on dose one
D. About ninety-seven percent
Correct Answer: D
Rationale: Each half-life adds half the remaining gap; five intervals close about ninety-seven
percent of the distance to steady state.
Question 6. Why must phenytoin doses be titrated in small increments at
therapeutic levels?
A. Its metabolism saturates, so small dose increases cause large concentration jumps
B. Its half-life shortens with each dose
C. It is eliminated unchanged by the lung
D. Its absorption stops at steady state
Correct Answer: A
Rationale: Zero-order saturation near therapeutic levels converts tiny increments into steep
concentration climbs—titration must crawl.
Question 7. Which process moves a drug from plasma into tissues according to its
lipophilicity and perfusion?
A. Absorption into portal blood
B. First-pass oxidation
NRG 200 Pharmacology for Human Caring Nursing Final Exam 2026/2027 | Verified Questions
, C. Distribution
D. Glomerular filtration alone
Correct Answer: C
Rationale: Lipid-soluble, well-perfused tissues receive drug fastest—that is distribution's
geography.
Question 8. Why can hypoalbuminemia raise the risk of toxicity from highly
protein-bound drugs?
A. Albumin destroys bound drugs slowly
B. Fewer binding sites leave more free, active drug circulating
C. Low albumin halts all absorption
D. Binding increases drug potency
Correct Answer: B
Rationale: Bound drug is the inactive reservoir; when albumin falls, the free fraction rises
without any dose change.
Question 9. Which hepatic enzyme family performs most drug biotransformation?
A. The renin-angiotensin enzymes
B. Pancreatic lipases
C. The cytochrome P450 system
D. Acetylcholinesterase family
Correct Answer: C
Rationale: The CYP enzyme cluster—especially 3A4 and 2D6—oxidizes the majority of
medications toward elimination.
Question 10. A steady drug level rises after erythromycin is added. What
mechanism fits?
A. Erythromycin doubles gastric emptying
B. The first drug's absorption is blocked
C. Kidney blood flow has doubled
D. Erythromycin inhibits the hepatic enzyme clearing the first drug
Correct Answer: D
Rationale: Macrolide enzyme inhibition slows clearance, letting the co-administered drug
accumulate toward toxicity.
Question 11. Rifampin is started in a client stabilized on warfarin. What should the
nurse anticipate?
A. Warfarin effect falls as rifampin induces metabolizing enzymes
