NR566 ADVANCED PHARMACOLOGY
MIDTERM EXAM STUDY GUIDE
(LATEST 2026/ 2027 UPDATE)
QUESTIONS AND 100% CORRECT
VERIFIED ANSWERS| GRADE A+
1. A patient with a history of heart failure is prescribed a medication that inhibits the Na+/K+-
ATPase pump. Which of the following electrolyte imbalances significantly increases the risk of
toxicity for this drug?
A. Hyperkalemia
B. Hypercalcemia
C. Hypokalemia
D. Hyponatremia
Answer: C
Conceptual Explanation: Digoxin inhibits the Na+/K+-ATPase pump. Hypokalemia
increases digoxin binding to the pump, significantly increasing the risk of digoxin toxicity.
2. When prescribing a non-selective beta-blocker like Propranolol, which comorbid condition
is considered a relative contraindication?
A. Hypertension
,B. Migraines
C. Hyperthyroidism
D. Asthma
Answer: D
Conceptual Explanation: Non-selective beta-blockers block both Beta-1 and Beta-2
receptors. Blocking Beta-2 receptors in the lungs can cause bronchoconstriction, which is
dangerous for patients with asthma or COPD.
3. A patient is started on Warfarin for atrial fibrillation. Which of the following cytochrome
P450 (CYP) interactions would lead to a dangerously elevated INR?
A. Concurrent use of a CYP2C9 inducer like Rifampin
B. Concurrent use of a CYP3A4 inducer like St. John’s Wort
C. Concurrent use of a CYP2C9 inhibitor like Amiodarone
D. Frequent consumption of leafy green vegetables
Answer: C
Conceptual Explanation: Warfarin is metabolized by CYP2C9. Inhibitors like Amiodarone
slow its metabolism, increasing blood levels and the INR, leading to a higher risk of
bleeding.
, 4. Which pharmacological property describes the relationship between the dose of a drug and
the magnitude of the biological response it produces?
A. Pharmacokinetics
B. Bioavailability
C. Pharmacodynamics
D. Therapeutic Index
Answer: C
Conceptual Explanation: Pharmacodynamics refers to what the drug does to the body,
specifically the biochemical and physiological effects and their mechanism of action.
5. A patient requires an ACE inhibitor for hypertension management but has a history of
developing a dry, hacking cough on Lisinopril. What is the physiological cause of this cough?
A. Increased levels of Angiotensin II
B. Inhibition of Aldosterone
C. Accumulation of Bradykinin
D. Decreased Nitric Oxide production
Answer: C
Conceptual Explanation: ACE inhibitors block the breakdown of bradykinin in the lungs.
The accumulation of bradykinin is responsible for the characteristic dry cough.
