SECTION I — INTRODUCTION
Questions 1–20
Question 1
A patient asks why pharmacokinetic principles are important when selecting a medication.
Which response by the advanced practice nurse is most accurate?
,A. Pharmacokinetics describes how a drug affects the body.
B. Pharmacokinetics describes how the body absorbs, distributes, metabolizes, and eliminates a
drug.
C. Pharmacokinetics determines whether a drug is classified as prescription or over-the-counter.
D. Pharmacokinetics primarily describes medication adherence.
Correct answer: B
Rationale: Pharmacokinetics describes what the body does to a medication through absorption,
distribution, metabolism, and excretion. Pharmacodynamics, by contrast, describes what the drug
does to the body. Understanding pharmacokinetics is essential for selecting doses, intervals, and
routes of administration.
Question 2
Which pharmacokinetic process determines the fraction of an orally administered medication
that reaches systemic circulation?
A. Distribution
B. Absorption
C. Bioavailability
D. Elimination
Correct answer: C
Rationale: Bioavailability represents the proportion of an administered dose that reaches
systemic circulation in an active form. Oral medications may have reduced bioavailability
because of incomplete absorption or first-pass hepatic metabolism.
Question 3
Which organ is primarily responsible for metabolism of many medications?
A. Heart
B. Liver
C. Spleen
D. Pancreas
Correct answer: B
Rationale: The liver is the major site of drug metabolism. Hepatic enzymes, particularly the
cytochrome P450 system, can transform medications into active, inactive, or sometimes toxic
metabolites.
,Question 4
A medication has a narrow therapeutic index. What is the most appropriate implication for
prescribing?
A. Dose adjustments are rarely required.
B. The medication has a wide margin of safety.
C. Small differences between therapeutic and toxic concentrations may exist.
D. Therapeutic drug monitoring is never useful.
Correct answer: C
Rationale: A narrow therapeutic index means the effective concentration and toxic concentration
are relatively close. Medications with narrow therapeutic windows may require careful dosing,
monitoring, and assessment for drug interactions.
Question 5
Which statement best describes pharmacodynamics?
A. It describes renal elimination of medications.
B. It describes medication absorption from the gastrointestinal tract.
C. It describes the biochemical and physiological effects of a medication on the body.
D. It describes the percentage of medication bound to plasma proteins.
Correct answer: C
Rationale: Pharmacodynamics concerns drug-receptor interactions and the resulting
physiological effects. Dose-response relationships, receptor activity, therapeutic effects, and
adverse effects are pharmacodynamic concepts.
Question 6
A medication produces a response by binding to and activating a receptor. The medication is best
described as a:
A. Competitive antagonist
B. Partial antagonist
C. Agonist
D. Enzyme inhibitor
Correct answer: C
, Rationale: An agonist binds to a receptor and activates it, producing a biological response.
Antagonists bind receptors but block or reduce activation.
Question 7
Which patient characteristic should prompt particular caution when prescribing medications
eliminated primarily through the kidneys?
A. Mild seasonal allergies
B. Reduced renal function
C. Increased visual acuity
D. Normal body temperature
Correct answer: B
Rationale: Reduced renal function can decrease medication clearance and increase systemic
exposure. Depending on the medication, dose reduction, increased dosing interval, or alternative
therapy may be necessary.
Question 8
Which principle is most important when initiating pharmacotherapy in an older adult?
A. Start with higher doses because metabolism is usually faster.
B. Older adults require identical doses to younger adults.
C. Consider age-related changes in pharmacokinetics and pharmacodynamics.
D. Avoid monitoring because older adults metabolize medications predictably.
Correct answer: C
Rationale: Aging can affect renal clearance, hepatic metabolism, body composition, receptor
sensitivity, and susceptibility to adverse effects. Individualized prescribing and monitoring are
therefore particularly important.
Question 9
What is the primary purpose of medication reconciliation?
A. To increase the number of medications a patient takes
B. To identify discrepancies among medication lists and actual medication use
C. To eliminate the need for patient education
D. To determine insurance eligibility
