NSG530 Exam 4 V1 | NSG 530 Advanced
Pathophysiology | Wilkes University
This exam preparation resource focuses on advanced concepts related to renal disorders,
musculoskeletal disease mechanisms, and reproductive system pathophysiology. The
material is designed to strengthen understanding of complex disease progression and advanced
physiological alterations affecting multiple body systems.
The questions included in this version closely mirror the style and complexity of actual advanced
pathophysiology exams. Detailed expert explanations are included to improve analytical
reasoning, clinical interpretation, and evidence-based disease analysis.
════════════════════════════════════
The Exam Covers:
• Renal pathophysiology
• Acute and chronic kidney disease
• Musculoskeletal disorders
• Autoimmune disease mechanisms
• Reproductive system disorders
• Bone metabolism abnormalities
• Urinary system dysfunctions
• Advanced inflammatory disorders
════════════════════════════════════
1. A patient is diagnosed with prerenal acute kidney injury (AKI). Which of the following
conditions is a likely cause of this diagnosis?
A. Acute tubular necrosis
B. Benign prostatic hyperplasia
C. Hypovolemic shock
D. Glomerulonephritis
Correct Answer: C
,Expert Explanation: Prerenal AKI is caused by factors that decrease systemic blood flow
and renal perfusion. Hypovolemic shock results in a significant drop in blood pressure,
leading to inadequate glomerular filtration. This differs from intrarenal causes which
damage the kidney tissue itself or postrenal causes which involve urinary tract obstruction.
2. Which clinical manifestation is a hallmark of nephrotic syndrome?
A. Proteinuria exceeding 3.5 g/day
B. Hypolipidemia
C. Gross hematuria
D. Urethritis
Correct Answer: A
Expert Explanation: Nephrotic syndrome is characterized by massive proteinuria due to
increased glomerular permeability to plasma proteins. This loss of protein leads to
hypoalbuminemia, which in turn causes systemic edema through decreased oncotic
pressure. The liver also increases lipid synthesis in response to low protein levels, resulting
in hyperlipidemia.
3. What is the primary pathophysiological mechanism involved in Rheumatoid Arthritis (RA)?
A. Wear and tear of articular cartilage
B. Uric acid crystal deposition in joints
C. Bacterial infection of the joint space
, D. Systemic autoimmune-mediated synovial inflammation
Correct Answer: D
Expert Explanation: Rheumatoid Arthritis is a chronic systemic autoimmune disorder that
primarily affects the synovial membrane of joints. Immune complexes trigger the release of
inflammatory cytokines like TNF-alpha, which leads to the formation of a pannus. This
pannus eventually invades and destroys the underlying cartilage and bone structure.
4. In Polycystic Ovary Syndrome (PCOS), which hormonal imbalance is typically observed?
A. Elevated androgens and insulin resistance
B. High levels of Estrogen and low LH
C. Decreased Testosterone and high Progesterone
D. Excessive Follicle Stimulating Hormone (FSH)
Correct Answer: A
Expert Explanation: PCOS is characterized by hyperandrogenism and frequent association
with insulin resistance and hyperinsulinemia. The excess insulin stimulates androgen
production by the ovarian theca cells and suppresses Sex Hormone Binding Globulin
(SHBG). This leads to the characteristic symptoms of hirsutism, acne, and ovulatory
dysfunction.
5. Why does chronic kidney disease (CKD) often lead to secondary hyperparathyroidism?
A. The kidneys produce too much Vitamin D
