SECTION ONE: QUESTIONS 1–100
Question 1.
Which pharmacokinetic process describes the movement of a medication from its site of
administration into the systemic circulation?
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Correct Answer: B. Absorption
Explanation: Absorption is the movement of a drug from its administration site into the
systemic circulation. Distribution occurs after the drug enters the circulation, metabolism
chemically modifies drugs, and excretion removes drugs or metabolites from the body.
Question 2.
A medication has a very high first-pass effect. Which route of administration would most
directly avoid hepatic first-pass metabolism?
A. Oral
B. Enteral
C. Sublingual
D. Gastric tube
,Correct Answer: C. Sublingual
Explanation: Sublingual administration allows medication to enter systemic circulation
through the oral mucosa, largely bypassing the gastrointestinal tract and hepatic first-pass
metabolism. Oral and gastric-tube administration expose medication to gastrointestinal
absorption and hepatic first-pass metabolism.
Question 3.
Which pharmacokinetic parameter describes the fraction of an administered dose that
reaches systemic circulation unchanged?
A. Bioavailability
B. Clearance
C. Half-life
D. Volume of distribution
Correct Answer: A. Bioavailability
Explanation: Bioavailability represents the proportion of an administered dose that reaches
systemic circulation in an active form. Intravenous administration has essentially complete
bioavailability because the medication is delivered directly into circulation.
Question 4.
A patient has severe hypoalbuminemia and receives a highly protein-bound medication.
What pharmacologic change is most likely?
A. Decreased free drug concentration
B. Increased free drug concentration
C. Increased renal protein binding
D. Complete elimination of the medication
Correct Answer: B. Increased free drug concentration
Explanation: Albumin binds many medications in the bloodstream. When albumin
concentration decreases, less drug is protein-bound and more remains pharmacologically
active in the free form, potentially increasing therapeutic and toxic effects.
Question 5.
Which organ is primarily responsible for the metabolism of most medications?
A. Heart
B. Liver
C. Spleen
D. Pancreas
Correct Answer: B. Liver
,Explanation: The liver is the principal organ responsible for drug metabolism. Hepatic
enzymes, particularly the cytochrome P450 system, transform many medications into
metabolites that may be active, inactive, or toxic.
Question 6.
A patient taking a medication with a narrow therapeutic index requires close monitoring
because:
A. The medication is ineffective at usual doses
B. The therapeutic and toxic concentrations are relatively close
C. The medication cannot be administered orally
D. The medication has no measurable serum concentration
Correct Answer: B. The therapeutic and toxic concentrations are relatively close
Explanation: A narrow therapeutic index means there is a small margin between an effective
concentration and a toxic concentration. Small changes in dose, metabolism, clearance, or
drug interactions may therefore cause toxicity.
Question 7.
Which statement best describes a drug agonist?
A. It binds to a receptor and produces a response
B. It permanently destroys a receptor
C. It prevents all receptor activity
D. It accelerates renal elimination
Correct Answer: A. It binds to a receptor and produces a response
Explanation: An agonist binds to a receptor and activates it to produce a biological response.
An antagonist binds to a receptor but blocks or reduces activation.
Question 8.
A competitive antagonist is administered with an agonist. Which effect is expected?
A. The antagonist permanently destroys the agonist
B. Increasing agonist concentration may overcome the antagonism
C. The antagonist always increases receptor activation
D. The agonist becomes chemically inactive
Correct Answer: B. Increasing agonist concentration may overcome the antagonism
Explanation: Competitive antagonists compete reversibly with agonists for the same
receptor site. Increasing the concentration of the agonist can therefore overcome the
competitive blockade.
, Question 9.
Which term describes the maximum effect that a drug can produce?
A. Potency
B. Efficacy
C. Affinity
D. Bioavailability
Correct Answer: B. Efficacy
Explanation: Efficacy refers to the maximum therapeutic effect a drug can produce. Potency
describes the amount of drug required to produce a specified effect.
Question 10.
Two medications produce the same maximum therapeutic effect, but one requires a lower
dose. Which medication is more potent?
A. The medication requiring the higher dose
B. The medication requiring the lower dose
C. Both are necessarily equally potent
D. Potency cannot be compared
Correct Answer: B. The medication requiring the lower dose
Explanation: Potency refers to the dose required to produce a particular effect. A more
potent medication produces the desired effect at a lower dose, assuming the comparison is
made under equivalent conditions.
Question 11.
A patient begins a medication that induces hepatic CYP450 enzymes. What effect can this
have on another medication metabolized by the same enzyme?
A. Increased concentration of the second medication
B. Decreased metabolism of the second medication
C. Increased metabolism and potentially decreased concentration of the second medication
D. Complete prevention of renal excretion
Correct Answer: C. Increased metabolism and potentially decreased concentration of the
second medication
Explanation: Enzyme induction increases metabolic activity. If the second medication is
metabolized by the induced enzyme, its plasma concentration may fall, potentially reducing
therapeutic effectiveness.
Question 12.
