NR565 ADVANCED PHARMACOLOGY
FINAL EXAM STUDY GUIDE
QUESTIONS AND VERIFIED ANSWERS
(2026/ 2027 UPDATE)- CHAMBERLAIN
1. A patient is taking a drug with a half-life of 6 hours. After how many hours will the drug
reach a steady-state concentration in the plasma?
A. 12 hours
B. 24 to 30 hours
C. 18 to 24 hours
D. 36 to 48 hours
Answer: B
Conceptual Explanation: Steady state is generally reached after 4 to 5 half-lives. 6 hours x
4 = 24 hours; 6 hours x 5 = 30 hours.
2. Which mechanism explains why ACE inhibitors often cause a persistent dry cough in some
patients?
A. Decreased levels of Angiotensin II
B. Accumulation of bradykinin in the lungs
C. Inhibition of aldosterone release
,D. Direct irritation of the bronchial mucosa
Answer: B
Conceptual Explanation: ACE (angiotensin-converting enzyme) also breaks down
bradykinin. Inhibiting ACE leads to bradykinin accumulation, which triggers the cough
reflex.
3. A 65-year-old male with a history of asthma and hypertension requires a beta-blocker.
Which of the following would be the most appropriate choice to minimize respiratory risks?
A. Metoprolol
B. Nadolol
C. Propranolol
D. Carvedilol
Answer: A
Conceptual Explanation: Metoprolol is a cardioselective (Beta-1) blocker, making it safer
for patients with asthma compared to non-selective blockers like Propranolol or Carvedilol.
4. When initiating statin therapy, which baseline laboratory test is no longer routinely
recommended for periodic monitoring unless the patient shows symptoms of toxicity?
A. Creatinine kinase (CK)
B. Total cholesterol
C. Alanine aminotransferase (ALT)
, D. HbA1c
Answer: A
Conceptual Explanation: Routine CK monitoring is not recommended unless the patient
reports muscle pain or weakness, whereas baseline ALT is still recommended.
5. Which of the following anticoagulants requires regular monitoring of the International
Normalized Ratio (INR)?
A. Warfarin
B. Dabigatran
C. Rivaroxaban
D. Apixaban
Answer: A
Conceptual Explanation: Warfarin is a vitamin K antagonist that requires frequent INR
monitoring to ensure therapeutic dosing (usually a goal of 2.0-3.0).
6. A patient presents with visual disturbances (yellow-green halos) and nausea. Which
medication is most likely causing these toxic symptoms?
A. Amiodarone
B. Digoxin
C. Lisinopril
D. Furosemide
