Question 1
Which term best describes "what the body does to the drug"?
A) Pharmacodynamics
B) Pharmacotherapeutics
C) Pharmacokinetics
D) Toxicology
Correct Answer: C) Pharmacokinetics
Rationale: Pharmacokinetics is the study of drug movement through the body, encompassing absorption,
distribution, metabolism, and excretion (ADME). Pharmacodynamics, in contrast, is "what the drug does to
the body."
Question 2
Which pharmacokinetic process describes the movement of a medication from the gastrointestinal tract
into the bloodstream?
A) Distribution
B) Absorption
C) Metabolism
D) Excretion
Correct Answer: B) Absorption
Rationale: Absorption is the movement of a medication from its site of administration into systemic
circulation. Oral medications generally must pass through the gastrointestinal tract before entering the
bloodstream.
Question 3
Which organ is primarily responsible for the metabolism of most medications?
A) Heart
B) Liver
,C) Spleen
D) Pancreas
Correct Answer: B) Liver
Rationale: The liver contains extensive enzyme systems, particularly the cytochrome P450 system, that
metabolize many medications. Liver dysfunction can therefore increase drug concentrations and toxicity
because medications may not be cleared efficiently.
Question 4
A medication has a half-life of 8 hours. Approximately how long would it take for the medication to reach
near-complete elimination after several half-lives?
A) 8 hours
B) 16 hours
C) 24 hours
D) Approximately 40 hours
Correct Answer: D) Approximately 40 hours
Rationale: Approximately five half-lives are generally required for a drug to be eliminated to about 3% of
its original concentration. Five half-lives of 8 hours equals approximately 40 hours.
Question 5
Which route of administration generally produces the fastest systemic drug effect?
A) Oral
B) Subcutaneous
C) Intramuscular
D) Intravenous
Correct Answer: D) Intravenous
Rationale: Intravenous administration places the medication directly into systemic circulation, resulting in
essentially complete bioavailability and a rapid effect.
Question 6
Which term describes the percentage of an administered drug dose that reaches systemic circulation
unchanged?
A) Potency
B) Bioavailability
,C) Efficacy
D) Therapeutic index
Correct Answer: B) Bioavailability
Rationale: Bioavailability represents the fraction of a drug dose that reaches systemic circulation. It is
100% for intravenous administration and less for other routes.
Question 7
A patient with severe hypoalbuminemia receives a medication that is normally 95% protein-bound.
Which pharmacologic consequence should the nurse anticipate?
A) Reduced absorption from the gastrointestinal tract
B) Increased free drug concentration and potentially greater toxicity
C) Accelerated renal elimination of the unbound drug
D) Complete prevention of drug distribution into tissues
Correct Answer: B) Increased free drug concentration and potentially greater toxicity
Rationale: Reduced albumin increases the unbound fraction of highly protein-bound medications.
Because unbound drug is pharmacologically active, the patient may experience exaggerated effects or
toxicity.
Question 8
What does the first-pass effect refer to?
A) The drug being excreted unchanged in the urine
B) The initial metabolism of an oral drug in the liver before it reaches systemic circulation
C) The immediate allergic reaction after administration
D) The drug binding to plasma proteins
Correct Answer: B) The initial metabolism of an oral drug in the liver before it reaches systemic
circulation
Rationale: The first-pass effect occurs when orally administered drugs are absorbed from the GI tract and
transported via the portal vein to the liver, where they are partially metabolized before reaching systemic
circulation.
Question 9
Which statement best describes the difference between an agonist and an antagonist?
A) An agonist blocks receptors; an antagonist activates receptors
B) An agonist activates receptors to produce a response; an antagonist blocks receptor activation
, C) Both agonists and antagonists produce the same effect
D) Antagonists are always more potent than agonists
Correct Answer: B) An agonist activates receptors to produce a response; an antagonist blocks
receptor activation
Rationale: An agonist binds to and activates a receptor, producing a desired response. An antagonist
binds to a receptor but does not activate it, instead blocking the receptor from being activated by agonists.
Question 10
A nurse administers a medication that has a half-life of 4 hours. How long will it take for the drug to be
reduced to approximately 25% of its original concentration?
A) 4 hours
B) 8 hours
C) 12 hours
D) 16 hours
Correct Answer: B) 8 hours
Rationale: After one half-life (4 hours): 50% remains. After two half-lives (8 hours): 25% remains.
Question 11
Which of the following is TRUE about a drug with a narrow therapeutic index?
A) It has a wide margin of safety
B) It requires close monitoring of serum drug levels
C) It has no risk of toxicity
D) It can be administered without dose adjustment
Correct Answer: B) It requires close monitoring of serum drug levels
Rationale: Narrow therapeutic index drugs have a small margin between therapeutic and toxic doses,
requiring careful serum level monitoring. Examples include digoxin, lithium, warfarin, and phenytoin.
Question 12
A patient with chronic kidney disease is prescribed a medication that is primarily eliminated through the
kidneys. Before administering the medication, which assessment finding should cause the nurse to
contact the healthcare provider?
A) The client reports taking the medication with breakfast
B) The client has a decreased urine output compared with the previous day
