NSG530 Final Exam V1 | NSG 530
Advanced Pathophysiology | Wilkes
University
This final exam preparation resource is designed to provide a comprehensive review of
advanced pathophysiological mechanisms, systemic disease progression, and clinical disease
interpretation covered throughout the course. The material integrates major pathophysiology
concepts into a realistic exam-style format.
The questions included in this version are structured to closely mirror actual final exam
assessments and strengthen clinical reasoning and advanced disease analysis skills. Detailed
expert explanations are included to improve concept integration and exam readiness.
════════════════════════════════════
The Exam Covers:
• Cellular and systemic disease mechanisms
• Cardiovascular and pulmonary disorders
• Neurological and endocrine dysfunctions
• Renal and musculoskeletal disorders
• Gastrointestinal pathophysiology
• Immune and inflammatory disorders
• Fluid and electrolyte imbalances
• Comprehensive pathophysiology review

1. A patient exhibits left ventricular enlargement in response to chronic hypertension. This
cellular adaptation is best described as:
A. Hyperplasia
B. Atrophy
C. Metaplasia
D. Hypertrophy
,Correct Answer: D
Expert Explanation: Hypertrophy is an increase in the size of cells in response to
mechanical load or stress. In chronic hypertension, the heart muscle must work harder to
pump blood, leading to the enlargement of individual cardiac myocytes. This differs from
hyperplasia, which involves an increase in the number of cells rather than their size.
2. Which mechanism is primarily responsible for the development of Type I hypersensitivity
reactions?
A. IgM and IgG activation of the complement system
B. T-cell mediated delayed immune response
C. IgE binding to mast cells and subsequent degranulation
D. Immune complex deposition in tissues
Correct Answer: C
Expert Explanation: Type I hypersensitivity is an immediate allergic reaction mediated by
IgE antibodies. Upon re-exposure to an allergen, IgE bound to mast cells triggers the
release of histamine and other inflammatory mediators. This process is the underlying
cause of conditions such as anaphylaxis, asthma, and seasonal allergies.
3. An arterial blood gas (ABG) result shows pH 7.30, PaCO2 52 mmHg, and HCO3 24 mEq/L.
What is the interpretation?
A. Respiratory Acidosis
B. Metabolic Acidosis
, C. Metabolic Alkalosis
D. Respiratory Alkalosis
Correct Answer: A
Expert Explanation: The pH is below 7.35, indicating acidosis. The PaCO2 is elevated
above 45 mmHg, suggesting a respiratory cause for the low pH. Since the bicarbonate
(HCO3) level is within the normal range, this is an uncompensated respiratory acidosis.
4. Which of the following is a characteristic finding in patients with Nephrotic Syndrome?
A. Hematuria and hypertension
B. Massive proteinuria and hypoalbuminemia
C. Decreased GFR and oliguria
D. Pyuria and flank pain
Correct Answer: B
Expert Explanation: Nephrotic syndrome is characterized by heavy protein loss in the
urine, typically exceeding 3.5 grams per day. This loss of protein leads to
hypoalbuminemia, which reduces oncotic pressure and results in generalized edema. It is
distinguished from nephritic syndrome, which is more commonly associated with
hematuria and red blood cell casts.
5. In the pathophysiology of Type 2 Diabetes Mellitus, the primary defect is:
A. Insulin resistance and relative insulin deficiency
