Introduction
The NR-568 Advanced Pharmacology for Adult-Gerontology
Primary Care examination assesses the graduate nursing student's
competency in pharmacotherapeutics for adults and older adults
in primary care settings. This comprehensive evaluation
emphasizes the application of pharmacokinetic and
pharmacodynamic principles to drug selection, dosing,
monitoring, and patient education. The multiple-choice and
scenario-based structure requires candidates to demonstrate
mastery of evidence-based prescribing, recognition of adverse
drug reactions, management of drug interactions, and adherence
to legal and ethical standards. The examination reflects the
,knowledge required for safe, effective pharmacological
management in adult-gerontology primary care practice.
Section One: Questions 1–100
Question 1
An 82-year-old patient is prescribed a medication that undergoes
extensive hepatic first-pass metabolism. Which age-related
physiologic change would most significantly increase the
bioavailability of this drug?
A. Increased gastric pH
B. Decreased hepatic blood flow and enzyme activity
C. Increased renal clearance
D. Decreased body fat percentage
🟢 Correct answer: B
🔴 RATIONALE: Aging is associated with decreased hepatic blood
flow and reduced activity of hepatic enzymes, which decreases
first-pass metabolism and increases the bioavailability of drugs
subject to extensive first-pass effects.
Question 2
Which pharmacokinetic parameter is most affected by the age-
related decrease in total body water and increase in body fat
percentage?
A. Absorption
B. Volume of distribution
C. Renal clearance
D. Protein binding
🟢 Correct answer: B
🔴 RATIONALE: The volume of distribution changes with aging
due to decreased total body water and increased body fat. Water-
,soluble drugs have a smaller volume of distribution, while lipid-
soluble drugs have a larger volume of distribution and prolonged
half-life.
Question 3
A 75-year-old patient with a serum albumin of 2.8 g/dL is
prescribed warfarin. What is the primary concern with this
patient's medication regimen?
A. Increased free drug concentration and bleeding risk
B. Decreased drug absorption
C. Increased renal excretion
D. Decreased drug metabolism
🟢 Correct answer: A
🔴 RATIONALE: Warfarin is highly protein-bound to albumin.
Hypoalbuminemia results in increased free (unbound) drug
concentration, increasing the pharmacologic effect and risk of
bleeding.
Question 4
The nurse practitioner is initiating pharmacotherapy for a 78-year-
old patient with hypertension and chronic kidney disease (eGFR
38 mL/min). Which principle should guide medication dosing?
A. Use standard adult doses regardless of renal function
B. Start at the lowest effective dose and titrate slowly
C. Avoid all antihypertensive medications
D. Double the initial dose to achieve therapeutic effect
🟢 Correct answer: B
🔴 RATIONALE: The principle of "start low, go slow" applies to
older adults, particularly those with renal impairment. Reduced
renal clearance increases the risk of drug accumulation and
toxicity.
, Question 5
Which of the following best describes the "prescribing cascade"?
A. A deliberate sequence of medications to treat a complex
condition
B. An adverse drug reaction treated with another medication,
leading to further adverse effects
C. A method for reducing polypharmacy
D. A standardized prescribing protocol
🟢 Correct answer: B
🔴 RATIONALE: The prescribing cascade occurs when an adverse
drug reaction is misinterpreted as a new medical condition,
leading to the prescription of another drug, which may cause
additional adverse effects.
Question 6
A 70-year-old patient with type 2 diabetes has an A1C of 8.5%.
Which medication class should be used with caution due to the
risk of hypoglycemia?
A. Metformin
B. SGLT2 inhibitors
C. Sulfonylureas
D. DPP-4 inhibitors
🟢 Correct answer: C
🔴 RATIONALE: Sulfonylureas (e.g., glipizide, glyburide) stimulate
insulin secretion regardless of glucose levels, increasing the risk of
hypoglycemia. This is especially concerning in older adults.
Glyburide should be avoided in older adults.
Question 7
A 68-year-old patient is prescribed metformin. Which laboratory
value must be monitored to ensure safe use?
