, NURS 5357: ADVANCED PATHOPHYSIOLOGY &
PHARMACOTHERAPEUTICS
EXAM 4 / FINAL COMPREHENSIVE PRACTICE EXAMINATION
Instructions & Exam Overview
This comprehensive examination contains 50 high-yield, NCLEX/NP board-style multiple-choice questions
covering advanced pathophysiology, clinical decision-making, and pharmacotherapeutics (Cardiology,
Endocrinology, Pulmonology, Neurology, Nephrology, GI, Infectious Disease, and Oncology). Complete detailed
rationales with correct and incorrect distractors follow the question bank.
PART I: COMPREHENSIVE QUESTION BANK (QUESTIONS 1 – 50)
Question 1. A 68-year-old male with a history of acute myocardial infarction 6 months ago presents with
worsening orthopnea, dyspnea on exertion, and bilateral 2+ lower extremity edema. Echocardiogram
reveals an ejection fraction (EF) of 32%. Which drug regimen represents the gold standard foundational
therapy (GDMT) to reduce mortality in this patient?
A. Furosemide, Isosorbide dinitrate, and Hydralazine
B. ARNI (Sacubitril/Valsartan), Beta-blocker (Carvedilol), MRA (Spironolactone), and SGLT2 inhibitor

Question 2. A 54-year-old female with chronic stable angina and hypertension is prescribed diltiazem.
What is the primary cellular mechanism of action of diltiazem that accounts for its antianginal effects?
A. Selective inhibition of funny current (I_f) channels in the SA node
B. Blockade of L-type voltage-gated calcium channels in vascular smooth muscle and cardiac myocytes
C. Direct stimulation of endothelial nitric oxide synthase (eNOS)
D. Irreversible inhibition of cyclooxygenase-1 (COX-1)
Question 3. A patient with persistent atrial fibrillation is being started on Amiodarone. Which of the
following baseline organ function assessments must be obtained prior to initiating therapy due to potential
toxicities?
A. Serum amylase, lipase, and abdominal ultrasound
B. Thyroid panel (TSH/free T4), baseline Chest X-ray, pulmonary function tests (PFTs), and liver function
tests (LFTs)
C. Renal biopsy, serum creatinine, and 24-hour urine protein
D. Serum calcium, parathyroid hormone, and bone densitometry
Question 4. Which hemodynamic profile is characteristic of Cardiogenic Shock?
A. High Cardiac Index (CI), low Systemic Vascular Resistance (SVR), low Pulmonary Capillary Wedge
Pressure (PCWP)
, B. Low Cardiac Index (CI), high Systemic Vascular Resistance (SVR), high Pulmonary Capillary Wedge
Pressure (PCWP)
C. Low Cardiac Index (CI), low Systemic Vascular Resistance (SVR), low Pulmonary Capillary Wedge
Pressure (PCWP)
D. High Cardiac Index (CI), high Systemic Vascular Resistance (SVR), high Pulmonary Capillary Wedge
Pressure (PCWP)
Question 5. A 72-year-old male with severe aortic stenosis presents with syncope and angina. What is the
fundamental pathophysiological adaptation of the left ventricle in response to chronic pressure overload
from aortic stenosis?
A. Eccentric left ventricular hypertrophy
B. Concentric left ventricular hypertrophy
C. Biventricular dilation with cardiac muscle thinning
D. Right ventricular dilation with cor pulmonale
Question 6. A 45-year-old female presents with fatigue, cold intolerance, weight gain, constipation, and
coarse hair. Laboratory studies show TSH of 14.2 mIU/L (High) and free T4 of 0.4 ng/dL (Low). Anti-thyroid
peroxidase (anti-TPO) antibodies are strongly positive. What is the underlying pathology?
A. Graves' disease causing TSH-receptor autoantibody activation
B. Hashimoto's thyroiditis characterized by autoimmune lymphocytic infiltration and follicular destruction
C. Subacute granulomatous thyroiditis following a viral upper respiratory infection
D. Pituitary adenoma causing secondary hypothyroidism
Question 7. A 28-year-old male with Type 1 Diabetes Mellitus presents to the ED with nausea, vomiting,
abdominal pain, and deep rapid respiration (Kussmaul breathing). Labs reveal Glucose 420 mg/dL, arterial
pH 7.18, Serum Bicarbonate 11 mEq/L, and Anion Gap 22. What is the primary biochemical driver of
ketoacid development in this patient?
A. Excessive peripheral glucose utilization causing lactic acid accumulation
B. Absolute insulin deficiency leading to uninhibited lipolysis and hepatic beta-oxidation of free fatty acids
C. Glucagon suppression leading to intracellular glycogen accumulation
D. Excessive renal excretion of glucose resulting in severe metabolic alkalosis
Question 8. Which medication class used in Type 2 Diabetes reduces glycemia by inhibiting renal glucose
reabsorption in the proximal convoluted tubule, while also demonstrating significant cardio-renal protective
benefits?
A. GLP-1 Receptor Agonists (e.g., Semaglutide)
B. SGLT2 Inhibitors (e.g., Empagliflozin, Dapagliflozin)
C. DPP-4 Inhibitors (e.g., Sitagliptin)
D. Thiazolidinediones (e.g., Pioglitazone)
Question 9. A 50-year-old male with Cushing's syndrome secondary to an ACTH-secreting pituitary
adenoma (Cushing's Disease) is evaluated. Which laboratory finding is expected during dynamic
endocrine testing?
A. High dose dexamethasone (8 mg) fails to suppress cortisol levels
B. High dose dexamethasone (8 mg) suppresses cortisol levels by >50%
C. Low dose dexamethasone (1 mg) suppresses cortisol levels completely
D. Baseline plasma ACTH level is undetectable or near zero
