NR566 Advanced Pharmacology for Care of the
Family – Week 4 Midterm/Final Exam Actual Exam
2026/2027 Complete 100 Questions with Detailed
Rationales – Pass Guaranteed – A+ Graded
Foundations of Advanced Pharmacology for Family Care (12 questions)
Q1: You're reviewing a patient's medication list and notice they take atorvastatin 40 mg
daily. You recall that atorvastatin is metabolized by which cytochrome P450 enzyme?
A. CYP2D6
B. CYP2C19
C. CYP3A4 [CORRECT]
D. CYP1A2
Correct Answer: C
Rationale: The best answer is CYP3A4. Atorvastatin undergoes extensive metabolism
via the CYP3A4 pathway, which is why you'll see significant interactions with drugs like
clarithromycin or itraconazole that strongly inhibit this enzyme. What you need to
remember for the midterm is that simvastatin and lovastatin are also CYP3A4
substrates, while pravastatin is not.
Q2: A 78-year-old patient with low albumin levels is prescribed a highly protein-bound
drug. What change in pharmacokinetics should you anticipate?
A. Increased free drug concentration and potential toxicity [CORRECT]
B. Decreased drug half-life
C. Reduced volume of distribution
D. Increased hepatic metabolism
Correct Answer: A
Rationale: That's correct because when albumin is low, there's less protein available to
bind the drug, leaving more free, active drug circulating. This is especially important in
,elderly or malnourished patients where you might need to start with lower doses of
highly protein-bound drugs like warfarin or phenytoin.
Q3: Which of the following is a strong inducer of CYP3A4 that could significantly reduce
the effectiveness of oral contraceptives?
A. Fluconazole
B. Rifampin [CORRECT]
C. Amiodarone
D. Cimetidine
Correct Answer: B
Rationale: The best answer is rifampin. Rifampin is a potent CYP3A4 inducer that can
increase metabolism of ethinyl estradiol and progestins, potentially causing
contraceptive failure. This matches the clinical reasoning you'll use in family practice
when managing TB treatment in women of childbearing age.
Q4: A patient is a CYP2D6 poor metabolizer. Which antidepressant might require dose
adjustment to avoid side effects?
A. Sertraline
B. Fluoxetine
C. Nortriptyline [CORRECT]
D. Escitalopram
Correct Answer: C
Rationale: That's correct because nortriptyline, a tricyclic antidepressant, is metabolized
by CYP2D6, and poor metabolizers can develop toxic levels at standard doses. You'll
see increased sedation and anticholinergic effects in these patients, so we typically
start low and go slow with TCAs when genetic information is available.
Q5: For a patient with chronic kidney disease stage 4, which renal function estimation
equation is preferred for drug dosing adjustments?
A. MDRD equation
B. Cockcroft-Gault equation [CORRECT]
C. Schwartz equation
D. Modification of Diet in Renal Disease only
Correct Answer: B
,Rationale: The best answer is the Cockcroft-Gault equation. While MDRD and CKD-EPI
are great for staging CKD and tracking progression, most drug dosing
recommendations in package inserts and references like Lexicomp are still based on
Cockcroft-Gault creatinine clearance calculations.
Q6: A patient asks why their levothyroxine needs to be taken on an empty stomach.
What is the primary reason?
A. Food decreases absorption by approximately 40-80% [CORRECT]
B. Food increases metabolism via first-pass effect
C. Food causes gastric irritation
D. Food alters protein binding
Correct Answer: A
Rationale: That's correct because food, especially fiber, coffee, and calcium
supplements, significantly interferes with levothyroxine absorption. The guidelines state
we need to take it 30-60 minutes before breakfast or at bedtime 4 hours after the last
meal for consistent TSH levels.
Q7: Which factor is most likely to increase drug absorption in an elderly patient?
A. Decreased gastric pH
B. Increased splanchnic blood flow
C. Use of proton pump inhibitors
D. Increased gastric emptying time [CORRECT]
Correct Answer: D
Rationale: The best answer is increased gastric emptying time. While many absorption
factors decline with age, delayed gastric emptying actually allows more time for drug
dissolution and absorption. However, this is a mixed blessing as it can also delay onset
and cause more variability in drug levels.
Q8: In shared decision-making for diabetes management, which factor should be
prioritized when selecting between an SGLT2 inhibitor and a GLP-1 agonist?
A. Cost and patient injection preference [CORRECT]
B. Only the HbA1c lowering potency
C. The physician's comfort with the medication
D. Avoiding all oral medications
Correct Answer: A
, Rationale: That's correct because both drug classes offer cardiovascular benefits, so
patient preferences regarding oral versus injectable routes, along with insurance
coverage and out-of-pocket costs, often drive the decision. This is central to
patient-centered care in family practice.
Q9: A patient with low health literacy is prescribed a complex medication regimen. What
is the most effective adherence strategy?
A. Provide detailed written handouts only
B. Use the teach-back method and simplify regimens when possible [CORRECT]
C. Increase the frequency of dosing to improve memory
D. Rely on the pharmacy's automated refill system
Correct Answer: B
Rationale: The best answer is using the teach-back method. Research shows that
asking patients to explain back in their own words what they understood helps identify
gaps, and simplifying to once-daily dosing when possible dramatically improves
adherence compared to complex multi-dose schedules.
Q10: Which pharmacodynamic interaction occurs when beta-blockers mask the tremors
and palpitations of hypoglycemia?
A. Synergistic effect
B. Pharmacokinetic potentiation
C. Physiologic antagonism
D. Masking of warning symptoms [CORRECT]
Correct Answer: D
Rationale: That's correct because this is a classic example of a pharmacodynamic
interaction where the drug blocks the adrenergic symptoms (tremors, sweating,
tachycardia) of low blood sugar without affecting the actual glucose levels. Diabetics on
beta-blockers need to be taught to check sugars when they feel "off" rather than waiting
for symptoms.
Q11: During medication reconciliation at hospital discharge, which high-alert medication
requires the most careful verification of the patient's current dose and new
prescriptions?
A. Lisinopril
