WEEK 1 — FOUNDATIONS IN
PHARMACOLOGY
Question 1
A nurse practitioner is prescribing a medication that undergoes extensive first-pass metabolism. Which
pharmacokinetic process is primarily responsible for reducing the amount of orally administered
medication that reaches systemic circulation?
A. Renal filtration
B. Hepatic metabolism
C. Protein binding
D. Glomerular secretion
Correct Answer: B. Hepatic metabolism
Rationale: First-pass metabolism occurs primarily in the liver after an orally administered medication
is absorbed from the gastrointestinal tract. Extensive hepatic metabolism can substantially reduce
systemic bioavailability.
Question 2
Which pharmacokinetic process describes the movement of a medication from the bloodstream into
body tissues?
,A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct Answer: B. Distribution
Rationale: Distribution is the movement of a drug from systemic circulation into tissues and body
fluids. Factors such as blood flow, lipid solubility, protein binding, and tissue permeability affect
distribution.
Question 3
A medication has a half-life of 8 hours. Approximately how much of the medication remains after 24
hours if elimination follows first-order kinetics?
A. 75%
B. 50%
C. 25%
D. 12.5%
Correct Answer: D. 12.5%
Rationale: Twenty-four hours represents three half-lives. The amount decreases by half with each half-
life: 100% → 50% → 25% → 12.5%.
Question 4
Which patient factor is most likely to increase the risk of medication accumulation in an older adult?
A. Increased renal clearance
B. Increased hepatic blood flow
C. Reduced renal function
D. Increased total body water
Correct Answer: C. Reduced renal function
Rationale: Renal function commonly declines with aging. Reduced renal clearance can increase drug
concentrations and prolong drug exposure, particularly for medications primarily eliminated by the
kidneys.
Question 5
A drug produces its therapeutic effect by binding to a receptor and activating it. This drug is best
described as a:
,A. Competitive antagonist
B. Partial antagonist
C. Agonist
D. Inverse inhibitor
Correct Answer: C. Agonist
Rationale: An agonist binds to a receptor and activates it, producing a biological response.
Question 6
A medication binds to a receptor but prevents activation by another drug. Which term best describes
this action?
A. Agonism
B. Antagonism
C. Potentiation
D. Absorption
Correct Answer: B. Antagonism
Rationale: An antagonist binds to a receptor without producing the receptor's activating response and
can block the action of an agonist.
Question 7
Which patient is at greatest risk for altered drug metabolism?
A. Healthy young adult with normal hepatic function
B. Older adult with significant hepatic impairment
C. Adolescent with normal renal function
D. Young adult with normal liver enzymes
Correct Answer: B. Older adult with significant hepatic impairment
Rationale: Hepatic impairment can decrease metabolism of medications that depend on hepatic
enzymes, potentially increasing serum drug concentrations and adverse effects.
Question 8
A medication is highly protein bound. The patient develops severe hypoalbuminemia. What is the most
likely consequence?
A. Increased free drug concentration
B. Decreased drug absorption
, C. Increased renal filtration of all medications
D. Complete elimination of the medication
Correct Answer: A. Increased free drug concentration
Rationale: Albumin binds many medications in the bloodstream. Reduced albumin can increase the
unbound fraction of highly protein-bound drugs, potentially increasing pharmacologic effects and
toxicity.
Question 9
Which medication-related factor most directly affects the time required to reach steady-state
concentration during repeated dosing?
A. Half-life
B. Tablet color
C. Route-independent taste
D. Molecular name length
Correct Answer: A. Half-life
Rationale: Steady state is generally reached after approximately four to five half-lives when a
medication is administered at a consistent dosing interval.
Question 10
A prescriber wants to minimize adverse drug reactions in an older adult. Which approach is most
appropriate?
A. Start with the highest recommended dose
B. Avoid reviewing concurrent medications
C. Start with a low dose and titrate cautiously
D. Assume renal function is normal
Correct Answer: C. Start with a low dose and titrate cautiously
Rationale: Older adults may have altered pharmacokinetics and increased sensitivity to medications.
Conservative dosing and careful titration can reduce medication-related harm.
Question 11
Which resource is specifically designed to identify potentially inappropriate medications in many older
adults?
A. Glasgow Coma Scale
B. Beers Criteria
