Pharmacology Final Exam Practice Questions
Pharmacokinetics & Pharmacodynamics
1. A patient is prescribed a medication that is considered a prodrug. What does this mean?
A) The drug is active immediately upon administration.
B) The drug requires biotransformation to become active.
C) The drug is excreted unchanged by the kidneys.
D) The drug has a high first-pass effect, rendering it inactive.
Answer: B
Rationale: A prodrug is pharmacologically inactive until it is metabolized in the body into an
active compound. An active drug does not require biotransformation to exert its effect .
2. A nurse is preparing to administer an oral medication. Which patient condition would most
significantly increase the drug's bioavailability?
A) Gastric bypass surgery
B) Hepatic cirrhosis
C) Concurrent administration with a cholinergic blocker
D) Administration with a high-fat meal
Answer: B
Rationale: Hepatic cirrhosis reduces liver function, decreasing the first-pass effect, which allows
more of the drug to reach systemic circulation. Gastric bypass reduces surface area for
absorption, typically decreasing bioavailability .
3. A patient's medication has a half-life of 4 hours. The nurse understands that after 12 hours,
what fraction of the original dose remains in the body?
A) 1/2
B) 1/4
C) 1/8
D) 1/16
1|Page
,Page 2 of 69
Answer: C
Rationale: 1/2 remains after one half-life (4 hours), 1/4 after two half-lives (8 hours), and 1/8
after three half-lives (12 hours) .
4. What is the purpose of a loading dose?
A) To maintain therapeutic levels for a prolonged period
B) To rapidly achieve therapeutic drug concentrations
C) To reduce the half-life of the drug
D) To increase the volume of distribution
Answer: B
Rationale: A loading dose is a higher initial dose given to rapidly achieve therapeutic
concentrations in the blood. This is especially important for drugs with long half-lives where
steady-state would otherwise take days to reach .
5. The volume of distribution (Vd) is best defined as:
A) The amount of drug in the body divided by the plasma concentration
B) The rate at which a drug is eliminated from the body
C) The amount of drug that reaches the systemic circulation
D) The concentration of drug at the receptor site
Answer: A
Rationale: The volume of distribution (Vd) is the theoretical volume that would be necessary to
contain the total amount of an administered drug at the same concentration that it is observed
in the blood plasma. A drug with a large Vd is highly distributed into tissues .
6. Which pharmacokinetic process involves the movement of a drug from the site of
administration into the bloodstream?
A) Distribution
B) Metabolism
C) Absorption
D) Excretion
Answer: C
Rationale: Absorption is the process by which a drug moves from its site of administration into
the bloodstream .
7. Which drug would be MOST likely to cross the blood-brain barrier?
A) A hydrophilic drug with high molecular weight
B) A lipid-soluble drug
C) A drug that is highly ionized
D) A drug that is strongly protein-bound
2|Page
,Page 3 of 69
Answer: B
Rationale: Lipid-soluble drugs cross the blood-brain barrier more readily. Hydrophilic, ionized,
or strongly protein-bound drugs are less likely to cross .
8. A patient asks why his drug to control high blood pressure has only one generic name and
two different trade names. What is your best response?
A) "Most drugs have different trade names that indicate different dosages."
B) "The two different trade names indicate that one is a more pure and safer drug than the
other."
C) "The generic name is the actual official drug name and the trade name is a brand owned by a
specific manufacturer."
D) "If you have insurance, you can get the trade name drug, which is usually more expensive
than the generic named drug."
Answer: C
Rationale: The generic name is the name assigned to the drug by the U.S. Adopted Names
Council and is not owned by anyone. The trade name (brand name) is the name provided and
owned by a specific drug's manufacturer .
9. Which feature of a drug agonist increases its potency?
A) It is water soluble.
B) It binds tighter and longer to its receptors than do other drugs.
C) It is excreted through the intestinal tract rather than through the kidneys.
D) It is administered intramuscularly rather than by the intravenous route.
Answer: B
Rationale: The longer a drug remains bound to its receptors and the more tightly it binds
increases its duration of response, making it more potent than a drug that binds with its
receptors for a shorter time .
10. The therapeutic index (TI) is defined as:
A) The ratio of the effective dose to the toxic dose
B) The ratio of the toxic dose to the effective dose (TD₅₀/ED₅₀)
C) The amount of drug that reaches systemic circulation
D) The rate at which a drug is eliminated
Answer: B
Rationale: The therapeutic index is the ratio of the toxic dose to the effective dose (TI =
TD₅₀/ED₅₀). A large therapeutic index indicates a wide margin of safety (e.g., penicillin), while a
narrow TI indicates a small margin between therapeutic and toxic effects, requiring monitoring
(e.g., digoxin, phenytoin) .

Cardiovascular Pharmacology
11. A patient is prescribed an ACE inhibitor for hypertension. Which adverse effect requires
the patient to be instructed to change positions slowly?
A) Dry, nonproductive cough
B) Orthostatic hypotension
C) Angioedema
D) Hyperkalemia
Answer: B
Rationale: ACE inhibitors cause vasodilation, which can lead to orthostatic hypotension. Patients
should be taught to rise slowly from a sitting or lying position to prevent dizziness and falls.
Angioedema is a severe, life-threatening allergic reaction requiring immediate medical attention
.
12. A nurse is caring for a client taking Propranolol. The nurse should hold the medication and
notify the provider if:
A) The heart rate is 54 beats per minute.
B) The blood pressure is 130/80 mmHg.
C) The client has a history of hypertension.
D) The client reports a headache.
Answer: A
Rationale: Propranolol is a nonselective beta blocker that lowers heart rate and blood pressure.
A heart rate of 54 bpm indicates bradycardia, which requires holding the medication and
notifying the provider .
13. A patient on long-term Propranolol therapy should be taught:
A) To double the dose if a dose is missed
B) Never to stop the medication abruptly
C) That the medication masks hypoglycemia symptoms
D) Both B and C
Answer: D
Rationale: Propranolol should never be stopped abruptly due to risk of rebound
hypertension/tachycardia. It also masks signs of hypoglycemia (tremor, tachycardia) in diabetic
patients .
14. Which medication is a potassium-sparing diuretic that requires monitoring for
hyperkalemia?
