Q1 Question 1 of 105
A 68-year-old male with hepatic cirrhosis is prescribed a medication that is normally metabolized extensively
by the liver. The nurse anticipates that the prescriber will need to do which of the following to ensure safe
administration?
A. Administer the drug intravenously to bypass the liver
B. Discontinue the drug because cirrhosis always prohibits hepatic drug use
C. Reduce the dose because impaired hepatic function slows drug metabolism and prolongs half-life
D. Increase the dose because the liver cannot absorb the drug
Correct Answer: C
Rationale:
In hepatic cirrhosis, drug metabolism is impaired, prolonging half-life and increasing drug accumulation, so
doses must be reduced. Increasing the dose would cause toxicity, IV administration does not bypass hepatic
metabolism since the drug still reaches the liver via systemic circulation, and cirrhosis does not always prohibit
drug use outright.
Q2 Question 2 of 105
A 55-year-old female receiving gentamicin for a gram-negative infection develops tinnitus and rising serum
creatinine. Which pharmacologic property of aminoglycosides best explains these adverse effects?
A. Pulmonary fibrosis due to alveolar deposition
B. Nephrotoxicity and ototoxicity due to drug accumulation in renal and inner ear tissues
C. Hepatotoxicity due to first-pass metabolism
D. Cardiotoxicity due to potassium channel blockade
Correct Answer: B
Rationale:
Aminoglycosides such as gentamicin accumulate in renal proximal tubular cells and the inner ear, causing
nephrotoxicity (rising creatinine) and ototoxicity (tinnitus). They do not cause hepatotoxicity from first-pass
effects, cardiotoxicity from potassium blockade, or pulmonary fibrosis.

, Q3 Question 3 of 105
A 42-year-old male patient asks why he should take his statin medication in the evening rather than the
morning. Which pharmacokinetic principle best supports this recommendation?
A. Cholesterol synthesis is highest at night, so statins taken in the evening are most effective
B. Statins cause drowsiness that helps with sleep
C. Statins must be taken with food to be absorbed
D. Statins have a short half-life and require morning dosing
Correct Answer: A
Rationale:
HMG-CoA reductase, the rate-limiting enzyme in cholesterol synthesis, is most active at night, so statins
(especially short-acting ones like simvastatin) are most effective when taken in the evening. The other options
do not explain evening dosing of statins.
Q4 Question 4 of 105
A 70-year-old female taking warfarin for atrial fibrillation is started on amiodarone for rhythm control. Three
days later, her INR is 5.5. Which pharmacokinetic mechanism best explains this interaction?
A. Amiodarone inhibits CYP2C9, reducing warfarin metabolism and increasing INR
B. Amiodarone increases warfarin absorption from the GI tract
C. Amiodarone displaces warfarin from tissue binding sites only
D. Amiodarone induces hepatic enzymes that metabolize warfarin
Correct Answer: A
Rationale:
Amiodarone is a potent inhibitor of CYP2C9, the enzyme that metabolizes warfarin's more active S-enantiomer,
leading to decreased warfarin clearance and elevated INR. Amiodarone does not significantly increase warfarin
absorption, displacement alone is not the primary mechanism, and enzyme induction would lower INR.

, Q5 Question 5 of 105
A patient receiving a medication intravenously asks the nurse why the IV route produces a faster effect than
the oral route. Which pharmacokinetic concept best explains this difference?
A. Oral medications are always inactivated by stomach acid
B. IV medications bind more strongly to plasma proteins
C. Oral medications have a shorter half-life than IV medications
D. IV administration bypasses first-pass metabolism and absorption, providing 100 percent bioavailability
Correct Answer: D
Rationale:
IV administration delivers drug directly into circulation, bypassing absorption and first-pass hepatic metabolism,
producing 100 percent bioavailability and rapid onset. Oral medications are not always inactivated by stomach
acid, protein binding does not differ by route, and route does not determine half-life.
Q6 Question 6 of 105
A nurse is preparing to administer morphine to a 75-year-old postoperative patient. The patient is concerned
about needing a smaller dose than a younger adult. Which age-related pharmacokinetic change best
supports this concern?
A. Increased hepatic blood flow accelerates metabolism
B. Decreased body fat reduces drug distribution
C. Decreased renal clearance and increased body fat prolong drug half-life in older adults
D. Increased gastric acidity speeds oral drug absorption
Correct Answer: C
Rationale:
Older adults experience decreased renal clearance and increased body fat, prolonging the half-life of lipophilic
drugs like morphine and requiring lower doses. Gastric acidity decreases rather than increases with age,
hepatic blood flow decreases, and body fat increases rather than decreases.
