,SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS (Questions 1–25)
1. A patient with renal impairment is prescribed a medication that is primarily
eliminated by the kidneys. Which pharmacokinetic parameter is most affected?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Answer: D) Excretion
Rationale: Renal impairment reduces the excretion of medications, leading to
accumulation and increased risk of toxicity. Lower doses or extended dosing
intervals are needed. This is a critical concept in pharmacokinetics.
2. A patient is started on a medication with a half-life of 24 hours. Approximately
how long will it take to reach steady-state concentrations?
A) 24 hours
B) 48 hours
C) 72 hours
D) 5 days (120 hours)
Answer: D) 5 days (120 hours)
Rationale: Steady-state is reached after approximately 5 half-lives. For a drug
with a 24-hour half-life, steady-state is achieved in about 5 days (5 × 24 = 120
hours).
3. A patient is prescribed a medication that is 95% protein-bound. What is the
clinical significance of this?
A) The drug has a rapid onset of action
,B) The drug is less likely to interact with other medications
C) The drug is highly bound and may be displaced by other highly protein-bound
drugs, increasing free drug concentration
D) The drug is primarily excreted unchanged in the urine
Answer: C) The drug is highly bound and may be displaced by other highly protein-
bound drugs, increasing free drug concentration
Rationale: Highly protein-bound drugs (≥90%) are at risk for displacement
interactions. When another drug competes for binding sites, the free (active)
concentration of the first drug increases, potentially causing toxicity.
4. A patient on warfarin (highly protein-bound) is started on a new medication that
also binds to albumin. Which effect should the nurse anticipate?
A) Decreased warfarin effect
B) Increased warfarin effect (bleeding risk)
C) No change in warfarin effect
D) Increased warfarin metabolism
Answer: B) Increased warfarin effect (bleeding risk)
Rationale: Displacement of warfarin from protein-binding sites increases free
warfarin concentration, leading to increased anticoagulant effect and bleeding risk.
This is a classic drug-drug interaction.
5. A medication has a narrow therapeutic index. This means:
A) The drug has a wide safety margin
B) The drug requires close monitoring of serum levels
C) The drug has no side effects
D) The drug is always safe
. Answer: B) The drug requires close monitoring of serum levels
Rationale: A narrow therapeutic index means there is a small difference between
the therapeutic dose and the toxic dose. Lithium, phenytoin, digoxin, and warfarin
are examples requiring serum level monitoring
, 6. Which of the following is a Phase I reaction in drug metabolism?
A) Glucuronidation
B) Oxidation
C) Sulfation
D) Acetylation
Answer: B) Oxidation
Rationale: Phase I reactions (oxidation, reduction, hydrolysis) introduce or expose
functional groups on the drug molecule, often via the cytochrome P450 system.
Phase II reactions (conjugation) involve attaching a polar molecule to the drug.
7. A patient is prescribed a prodrug. The advanced practice nurse explains that:
A) The medication is active immediately upon administration
B) The medication is inactive until metabolized to its active form
C) The medication has no therapeutic effect
D) The medication is only active in the liver
Answer: B) The medication is inactive until metabolized to its active form
Rationale: A prodrug is a pharmacologically inactive compound that is metabolized
to an active drug. This can improve bioavailability or reduce side effects. Examples
include enalapril (to enalaprilat) and codeine (to morphine).
8. A patient with hepatic impairment is prescribed a medication that is primarily
metabolized by the liver. The nurse should anticipate:
A) A lower dose is needed
B) A higher dose is needed
C) The same dose is appropriate
D) The medication should be avoided entirely
