Q1 Question 1 of 100
A 55-year-old male with hypertension is prescribed propranolol, a high first-pass metabolism
drug. After oral administration, only 25% of the dose reaches systemic circulation. The nurse
understands that the bioavailability of this medication is most directly affected by which
process?
A. Extensive hepatic metabolism during first pass through the portal circulation and liver
B. Rapid renal excretion before the drug can distribute to target tissues
C. Binding of the drug to plasma proteins preventing receptor interaction
D. Distribution of the drug into adipose tissue reducing available circulating concentration
Correct Answer: A
Rationale:
Propranolol undergoes extensive first-pass hepatic metabolism, meaning a large portion is metabolized by
the liver before reaching systemic circulation, reducing its oral bioavailability to approximately 25%. Renal
excretion, protein binding, and adipose distribution affect drug levels but are not the primary determinant of
the reduced bioavailability seen with high first-pass drugs.
Q2 Question 2 of 100
A 42-year-old female takes phenytoin for seizure control. Her serum phenytoin level rises
disproportionately after a small dose increase. The nurse recognizes this is due to which
pharmacokinetic property?
A. Linear first-order kinetics where a constant fraction is eliminated per unit time
B. Capacity-limited metabolism with saturation of hepatic enzymes near the therapeutic range
C. Zero-order kinetics where a constant amount is eliminated regardless of dose
D. Prolonged half-life due to reduced renal clearance in chronic kidney disease
Correct Answer: B
Rationale:
Phenytoin exhibits capacity-limited (Michaelis-Menten) kinetics where hepatic enzymes become saturated
near the therapeutic range, causing small dose increases to produce disproportionately large increases in
serum levels. Zero-order kinetics describes constant-rate elimination but does not capture the transition from
first-order to zero-order. First-order kinetics would produce proportional increases.

Q3 Question 3 of 100
A 68-year-old male with atrial fibrillation is started on warfarin. Genetic testing reveals he is a
CYP2C9 poor metabolizer. The nurse anticipates which dosing adjustment will be needed?
A. Higher warfarin doses to compensate for reduced activation of the prodrug
B. No adjustment needed because warfarin is primarily renally eliminated
C. Lower warfarin doses due to reduced clearance and increased anticoagulant effect
D. Switching to a direct thrombin inhibitor to avoid all CYP-mediated interactions
Correct Answer: C
Rationale:
CYP2C9 poor metabolizers have reduced capacity to metabolize the more potent S-enantiomer of warfarin,
leading to increased drug exposure and bleeding risk. These patients require lower initial doses and careful
titration. Warfarin is hepatically metabolized, not renally eliminated, so CYP2C9 status directly affects dosing
requirements.
Q4 Question 4 of 100
A 35-year-old female receives a prescription for oral contraceptives containing ethinyl
estradiol. She also takes rifampin for tuberculosis. The nurse counsels her that this
combination may reduce contraceptive efficacy due to which mechanism?
A. Rifampin inhibits CYP3A4 reducing the metabolism of ethinyl estradiol and causing toxicity
B. Rifampin impairs gastrointestinal absorption of ethinyl estradiol through altered intestinal pH
C. Rifampin competes for protein binding sites displacing ethinyl estradiol from albumin
D. Rifampin induces CYP3A4 increasing the metabolism of ethinyl estradiol and reducing its levels
Correct Answer: D
Rationale:
Rifampin is a potent CYP3A4 inducer that accelerates the metabolism of ethinyl estradiol, reducing its
plasma concentration and contraceptive efficacy. Women taking both medications should use alternative or
additional contraceptive methods. CYP induction increases metabolism rather than reducing it, and the
interaction is metabolic, not absorptive or protein-binding.

Q5 Question 5 of 100
A 50-year-old male with diabetes is prescribed a medication with a half-life of 6 hours. If the
medication is dosed every 6 hours, approximately how long will it take to reach steady state?
A. 24 to 30 hours representing approximately four to five half-lives for steady state
B. 12 to 18 hours representing two to three half-lives for near-complete accumulation
C. 6 hours which equals one half-life and the time to reach full therapeutic effect
D. 48 hours because steady state requires at least eight half-lives of continuous dosing
Correct Answer: A
Rationale:
Steady state is reached after approximately 4 to 5 half-lives of a drug. With a half-life of 6 hours, steady
state would be achieved in 24 to 30 hours. One half-life reaches only 50% of steady state, and 8 half-lives
far exceeds the required time. Understanding this concept is essential for determining when therapeutic drug
monitoring should occur.
Q6 Question 6 of 100
A 60-year-old female with heart failure is prescribed digoxin. Her serum albumin level is 2.0
g/dL due to malnutrition. How does hypoalbuminemia affect the pharmacodynamics of digoxin
in this patient?
A. Decreased free digoxin levels because more drug is bound to the limited albumin available
B. Increased free digoxin levels leading to enhanced pharmacologic effect and potential toxicity
C. No significant effect because digoxin has minimal protein binding in the circulation
D. Reduced drug effect because the low albumin impairs digoxin receptor sensitivity in the
myocardium
Correct Answer: B
Rationale:
Although digoxin has only about 20 to 30% protein binding, hypoalbuminemia can still increase the free
(unbound) fraction of the drug, leading to enhanced pharmacologic effect and potential toxicity. More free
drug is available to interact with receptors. The effect is not due to increased binding or reduced receptor
sensitivity.
