NURS 6521 ADVANCED
PHARMACOLOGY FINAL EXAM
QUESTIONS ANDB ANSWERS
1. Which pharmacokinetic process is most significantly affected by the ‘first-pass effect’ when
a drug is administered orally?
A. Distribution
B. Excretion
C. Metabolism
D. Absorption
Answer: C
Conceptual Explanation: The first-pass effect occurs when a drug is metabolized by
enzymes in the liver or gut wall before reaching systemic circulation, primarily affecting
the metabolism of oral medications.
2. A patient with a history of heart failure is prescribed Lisinopril. Which mechanism explains
the development of a persistent, dry cough in this patient?
A. Inhibition of prostaglandins
,B. Direct irritation of the tracheal mucosa
C. Increase in nitric oxide levels
D. Accumulation of bradykinin
Answer: D
Conceptual Explanation: ACE inhibitors prevent the breakdown of bradykinin, leading to
its accumulation in the lungs, which triggers the characteristic dry cough.
3. When monitoring a patient on Warfarin therapy, which laboratory value is the primary
indicator for adjusting the dosage?
A. Partial Thromboplastin Time (PTT)
B. Bleeding time
C. International Normalized Ratio (INR)
D. Platelet count
Answer: C
Conceptual Explanation: The INR is the standardized measurement used to monitor the
effectiveness and safety of Warfarin therapy, with a typical target range of 2.0 to 3.0 for
most indications.
4. A patient with Type 2 Diabetes is starting Metformin. What is the most critical
contraindication related to renal function?
A. Presence of trace proteinuria
, B. Serum Creatinine of 1.2 mg/dL
C. Glomerular Filtration Rate (GFR) less than 30 mL/min
D. History of kidney stones
Answer: C
Conceptual Explanation: Metformin is contraindicated in patients with a GFR below 30
mL/min due to the significantly increased risk of lactic acidosis.
5. Fluoroquinolones, such as Ciprofloxacin, carry a Black Box Warning for which of the
following adverse effects?
A. Hepatotoxicity
B. Aplastic anemia
C. Tendon rupture
D. Acute renal failure
Answer: C
Conceptual Explanation: Fluoroquinolones are associated with an increased risk of
tendonitis and tendon rupture, particularly the Achilles tendon, especially in older adults
and those taking corticosteroids.
6. A patient is taking Amiodarone for ventricular arrhythmias. Which organ system requires
baseline and periodic monitoring due to potential toxicity?
A. Musculoskeletal system
