Fundamentals of Pharmacology (Questions 1–20)
Q1: A nursing student asks the instructor to explain the difference between pharmacokinetics and
pharmacodynamics. Which response by the instructor is most accurate?
A. Pharmacokinetics describes what the body does to the drug; pharmacodynamics describes what the
drug does to the body.
B. Pharmacokinetics describes what the drug does to the body; pharmacodynamics describes what the
body does to the drug.
C. Pharmacokinetics and pharmacodynamics are interchangeable terms that describe drug metabolism.
[CORRECT]
D. Pharmacokinetics only applies to oral medications, while pharmacodynamics applies to all routes.
Correct Answer: C
Rationale: Pharmacokinetics covers ADME (absorption, distribution, metabolism, excretion), and
pharmacodynamics covers drug-receptor interactions and effects—this is the classic distinction every
nursing student must memorize.
Q2: A patient is prescribed a medication with a narrow therapeutic index. The nurse understands that
this means which of the following?
A. The drug has a wide margin of safety between therapeutic and toxic doses.
B. There is a small difference between the therapeutic dose and the toxic dose, requiring close
monitoring. [CORRECT]
C. The drug is safe to administer without monitoring serum levels.
,D. The therapeutic index refers only to the drug's half-life.
Correct Answer: B
Rationale: A narrow therapeutic index means the gap between effective and toxic is razor-thin, so you'll
be watching labs like a hawk—think digoxin, lithium, or warfarin.
Q3: The nurse is reviewing a medication's pharmacokinetic profile and notes the half-life is 8 hours.
Approximately how long will it take for the drug to reach steady-state concentration with regular
dosing?
A. 8 hours
B. 16 hours
C. 24 hours
D. 40 hours [CORRECT]
Correct Answer: D
Rationale: Steady state is reached in about 4 to 5 half-lives, so 5 × 8 hours = 40 hours—this is why
loading doses exist for drugs with long half-lives when you need effect fast.
Q4: A patient asks the nurse why some medications are given orally and others intravenously. The
nurse's best response is:
A. "IV medications are always stronger than oral medications."
B. "The route depends on the desired onset, the drug's properties, and the patient's condition."
[CORRECT]
C. "Oral medications bypass first-pass metabolism, making them more effective."
D. "IV drugs have 100% bioavailability because they go through the liver first."
Correct Answer: B
Rationale: Route selection is all about the clinical picture—onset needs, first-pass considerations,
patient status, and drug characteristics all factor in.
Q5: The nurse is caring for a patient receiving a new medication. Which factor would most likely
increase the drug's distribution to tissues?
,A. High plasma protein binding
B. Low lipid solubility
C. High lipid solubility [CORRECT]
D. Large molecular size
Correct Answer: C
Rationale: Lipid-soluble drugs cross cell membranes easily and distribute widely into tissues, while
water-soluble drugs tend to stay in the vascular space.
Q6: A patient with liver cirrhosis is prescribed a drug that undergoes extensive hepatic metabolism. The
nurse anticipates which adjustment?
A. The dose should be increased because the liver metabolizes drugs faster in cirrhosis.
B. The dose should be decreased or the dosing interval extended due to impaired metabolism.
[CORRECT]
C. No adjustment is needed because the kidneys will compensate for liver dysfunction.
D. The drug should be switched to an intravenous route only.
Correct Answer: B
Rationale: A damaged liver can't break drugs down efficiently, so you'll either decrease the dose or
space it out more to prevent toxicity from accumulation.
Q7: The nurse is teaching a patient about a medication that is a prodrug. Which statement by the
patient indicates understanding?
A. "This medication is inactive until my body converts it to its active form." [CORRECT]
B. "This medication will work immediately because it is already active."
C. "A prodrug is a drug that prevents other drugs from working."
D. "Prodrugs are only given by the intravenous route."
Correct Answer: A
Rationale: Prodrugs like enalapril or codeine need metabolic conversion to become pharmacologically
active—patients with impaired conversion pathways may not respond as expected.
, Q8: A nurse is reviewing receptor theory and understands that an agonist medication does which of the
following?
A. Blocks the receptor and prevents any response
B. Binds to the receptor and produces a response [CORRECT]
C. Binds to the receptor but produces no response
D. Destroys the receptor permanently
Correct Answer: B
Rationale: Agonists turn the receptor on and trigger a cellular response, while antagonists block the
receptor without activating it—think of it as a key that actually starts the car versus one that just jams
the ignition.
Q9: A patient is receiving a drug that is a competitive antagonist. The nurse understands that the effect
of this drug can be overcome by:
A. Decreasing the dose of the agonist
B. Increasing the dose of the agonist [CORRECT]
C. Administering the antagonist by a different route
D. Competitive antagonists cannot be overcome by any means
Correct Answer: B
Rationale: Competitive antagonists fight agonists for the same receptor sites, so flooding the system
with more agonist can outcompete the blocker and restore the response.
Q10: The nurse is caring for a patient with renal impairment who is receiving a drug primarily excreted
by the kidneys. Which action is most appropriate?
A. Increase the dose to compensate for decreased renal function.
B. Monitor renal function and adjust the dose or interval accordingly. [CORRECT]
C. Switch to a topical formulation to bypass renal excretion.
D. Administer the medication with food to enhance renal clearance.
