KAPLAN PHARMACOLOGY REVIEW PRACTICE EXAM
2026/2027 COMPLETE (100) CURRENT TESTING
QUESTIONS AND CORRECT ANSWERS WITH DETAILED
RATIONALES.
PHARMACOLOGY
Prepare for the Kaplan Pharmacology Review Practice Exam with a focused study
resource covering essential medication and pharmacology concepts for nursing
practice. It supports review of drug classifications, therapeutic effects, adverse
reactions, safety considerations, medication administration, and patient education.
Use the material to reinforce pharmacology knowledge, practice clinical decision-
making, and identify areas that may require additional study. This resource is best
suited for nursing students and NCLEX candidates preparing for pharmacology
assessments and comprehensive review.
MULTIPLE CHOICE.
PHARMACOKINETICS & PHARMACODYNAMICS
1. A nurse is preparing to administer a medication that has a high first-
pass effect. The nurse should anticipate that this medication will:
A) Be rapidly absorbed through the skin
B) Be extensively metabolized by the liver before reaching systemic circulation
C) Have a prolonged duration of action
D) Be excreted unchanged in the urine
Answer: B) Be extensively metabolized by the liver before reaching
systemic circulation
Rationale: The first-pass effect refers to the metabolism of a drug in the
liver before it reaches systemic circulation. Drugs with high first-pass
metabolism have reduced bioavailability and may require higher oral
doses or alternative routes (IV, sublingual) to achieve therapeutic effects.

2. A nurse is teaching a client about a medication that has a half-life of 12
hours. Which statement by the client indicates understanding?
A) "The medication will be completely eliminated from my body in 12 hours"
B) "It takes 12 hours for half of the medication to be eliminated from my body"
C) "I need to take the medication every 12 hours to maintain a steady state"
D) "The medication will reach peak effect in 12 hours"
Answer: B) "It takes 12 hours for half of the medication to be eliminated
from my body"
Rationale: Half-life is the time required for the plasma concentration of a
drug to decrease by 50%. It takes approximately 4-5 half-lives for a drug to
be completely eliminated. Steady state is typically reached after 4-5 half-
lives of regular dosing.
3. A nurse is administering a medication that is a weak acid. The nurse
understands that this medication will be better absorbed in which part of
the gastrointestinal tract?
A) Stomach (acidic environment)
B) Small intestine (alkaline environment)
C) Colon
D) Rectum
Answer: A) Stomach (acidic environment)
Rationale: Weak acids are better absorbed in acidic environments
(stomach) because they are non-ionized and lipid-soluble, allowing easier
passage across cell membranes. Weak bases are better absorbed in
alkaline environments (small intestine).
4. A nurse is reviewing the concept of bioavailability with a client. Which
statement best describes bioavailability?
, Page 3 of 46
A) The amount of drug that is bound to plasma proteins
B) The percentage of the administered drug that reaches systemic circulation
C) The time it takes for the drug to produce a therapeutic effect
D) The route of administration of the drug
Answer: B) The percentage of the administered drug that reaches
systemic circulation
Rationale: Bioavailability is the fraction of the administered drug that
reaches systemic circulation. IV administration has 100% bioavailability.
Oral drugs have variable bioavailability due to first-pass metabolism and
absorption factors.
5. A nurse is monitoring a client for signs of drug toxicity. Which factor
increases the risk of drug toxicity in older adults?
A) Increased renal clearance
B) Decreased liver function and reduced renal function
C) Increased protein binding
D) Increased gastric motility
Answer: B) Decreased liver function and reduced renal function
Rationale: Older adults have decreased liver function (reduced
metabolism) and reduced renal function (decreased excretion),
increasing the risk of drug accumulation and toxicity. They also have
decreased protein binding, which can increase free drug levels.
6. A nurse is teaching a client about the importance of taking a medication
with food to reduce gastrointestinal upset. This is an example of:
A) Pharmacokinetics
B) Pharmacodynamics
C) Pharmacotherapeutics
, Page 4 of 46
D) Pharmacognosy
Answer: A) Pharmacokinetics
Rationale: Pharmacokinetics is the study of how the body affects a drug,
including absorption, distribution, metabolism, and excretion. Taking a
medication with food affects its absorption. Pharmacodynamics is the
study of how the drug affects the body.
7. A nurse is administering a medication that is highly protein-bound.
Which condition would increase the risk of toxicity?
A) Hypoalbuminemia
B) Hyperalbuminemia
C) Decreased liver function
D) Increased renal function
Answer: A) Hypoalbuminemia
Rationale: Highly protein-bound drugs are primarily bound to albumin.
Hypoalbuminemia (low albumin levels) results in more free (active) drug,
increasing the risk of toxicity. Conditions such as liver disease, nephrotic
syndrome, and malnutrition can cause hypoalbuminemia.
8. A nurse is calculating the maintenance dose of a medication for a client
with renal impairment. Which pharmacokinetic process is most affected
by renal impairment?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Answer: D) Excretion
Rationale: Renal impairment primarily affects drug excretion
