Q1: A nursing student asks about the difference between pharmacokinetics and
pharmacodynamics. Which explanation best describes pharmacodynamics?
A. The movement of the drug through the body, including absorption and excretion.
B. How the body metabolizes the drug using the CYP450 system.
C. The study of the biochemical and physiologic effects of the drug on the body.
D. The duration of time a drug remains in the system at a therapeutic level.
Correct Answer: C
Rationale: The best answer is the study of the biochemical and physiologic effects of
the drug on the body because pharmacodynamics focuses on what the drug does to the
body (receptor binding, mechanism of action), whereas pharmacokinetics is what the
body does to the drug.
Q2: You are prescribing a medication that is a potent CYP3A4 inhibitor. What effect
should you expect on the plasma levels of another drug metabolized by this enzyme?
A. The plasma level of the other drug will decrease.
B. The plasma level of the other drug will increase.
C. The metabolism of the other drug will shift to the renal pathway.
D. The half-life of the other drug will be shortened.
Correct Answer: B
Rationale: The best answer is the plasma level of the other drug will increase because
inhibitors block the enzyme responsible for breaking down the substrate drug, causing it
to accumulate in the body and potentially reach toxic levels.
Q3: A 75-year-old patient is taking multiple medications. You consult the Beers Criteria.
Which of the following medications is typically included on this list as potentially
inappropriate for older adults?
A. Metformin
B. Lisinopril
,C. Diphenhydramine (Benadryl)
D. Atorvastatin
Correct Answer: C
Rationale: The best answer is Diphenhydramine (Benadryl) because it is highly
anticholinergic and carries significant risks for older adults, such as confusion, sedation,
urinary retention, and falls.
Q4: A pregnant patient in her first trimester requires an antihypertensive. Which
medication is the preferred first-line agent according to current guidelines for managing
chronic hypertension in pregnancy?
A. Lisinopril
B. Methyldopa
C. Losartan
D. Furosemide
Correct Answer: B
Rationale: The best answer is Methyldopa because it has a long history of safety and
efficacy in pregnancy, whereas ACE inhibitors and ARBs are contraindicated due to the
risk of fetal renal damage.
Q5: You are calculating a dose for a pediatric patient weighing 22 kg. The standard
order is 10 mg/kg/day divided into two doses. What is the total daily dose?
A. 110 mg
B. 220 mg
C. 44 mg
D. 22 mg
Correct Answer: B
Rationale: The best answer is 220 mg because 10 mg multiplied by the patient's weight
(22 kg) equals 220 mg total for the day.
Q6: A breastfeeding mother asks about the safety of using over-the-counter
antihistamines for allergies. Which medication is generally considered compatible with
breastfeeding due to low levels in breast milk?
A. Diphenhydramine
B. Cetirizine
C. Chlorpheniramine
D. Brompheniramine
Correct Answer: B
Rationale: The best answer is Cetirizine because it is a second-generation
antihistamine with minimal transfer into breast milk and causes less sedation in the
infant compared to first-generation antihistamines like diphenhydramine.
, Q7: A patient with end-stage renal disease (ESRD) requires an antibiotic. Which
modification is most critical for this patient?
A. Increase the frequency of dosing.
B. Extend the dosing interval or reduce the dose.
C. Avoid oral medications entirely.
D. Add a second agent to prevent resistance.
Correct Answer: B
Rationale: The best answer is extend the dosing interval or reduce the dose because
drugs excreted primarily by the kidneys will accumulate in patients with renal failure,
leading to toxicity if dosing is not adjusted.
Q8: Which medication requires a "Black Box Warning" regarding the risk of tendon
rupture?
A. Ciprofloxacin
B. Azithromycin
C. Doxycycline
D. Amoxicillin
Correct Answer: A
Rationale: The best answer is Ciprofloxacin because fluoroquinolones carry a Black Box
Warning for an increased risk of tendinitis and tendon rupture, which can occur even
months after stopping the drug.
Q9: A patient is prescribed a medication that is a "prodrug." What does this imply about
its pharmacokinetics?
A. The drug is inactive until it is metabolized by the liver.
B. The drug works immediately upon absorption.
C. The drug is excreted unchanged by the kidneys.
D. The drug has a very high first-pass effect.
Correct Answer: A
Rationale: The best answer is the drug is inactive until it is metabolized by the liver
because a prodrug is administered in an inactive form and must undergo
biotransformation to become pharmacologically active.
Q10: You are treating a 6-year-old child for an infection. The parent asks why you
cannot just give them "half an adult pill." What is the most accurate response regarding
pediatric pharmacokinetics?
A. Children have slower metabolism than adults.
B. Children have a higher percentage of body water and immature liver enzymes.
C. Children absorb drugs less efficiently than adults.
D. Children are less sensitive to drug toxicities.
Correct Answer: B
