NURS 6501 ADVANCED
PATHOPHYSIOLOGY FINAL EXAM
COMPREHENSIVE REVIEW QUESTIONS
AND ANSWERS
1. A patient with chronic kidney disease (CKD) presents with severe anemia. What is the
primary pathophysiological reason for this?
A. Excessive loss of red blood cells in the urine
B. Inability of the kidney to secrete erythropoietin
C. Insufficient vitamin B12 absorption in the distal tubule
D. Destruction of red blood cells by uremic toxins
Answer: B
Conceptual Explanation: In CKD, the kidneys fail to produce enough erythropoietin,
which is the hormone responsible for stimulating the bone marrow to produce red blood
cells.
,2. In Type 1 Diabetes Mellitus, the destruction of pancreatic beta cells is primarily mediated
by which mechanism?
A. Insulin resistance in peripheral tissues
B. Age-related atrophy of the pancreas
C. Excessive intake of refined sugars
D. T-cell mediated autoimmune attack
Answer: D
Conceptual Explanation: Type 1 Diabetes is an autoimmune disease where T-cells destroy
the insulin-producing beta cells in the islets of Langerhans.
3. A 55-year-old male presents with a ‘barrel chest’ and productive cough. Spirometry shows
a decreased FEV1/FVC ratio. Which condition is most likely?
A. Restrictive lung disease
B. Acute respiratory distress syndrome
C. Pulmonary fibrosis
D. Chronic Obstructive Pulmonary Disease (COPD)
Answer: D
Conceptual Explanation: A barrel chest and decreased FEV1/FVC ratio are classic signs of
air trapping and airway obstruction characteristic of COPD.
, 4. Which electrolyte imbalance is most commonly associated with the release of B-type
natriuretic peptide (BNP) in heart failure?
A. Hypocalcemia
B. Hyperkalemia
C. None, it is a response to ventricular stretch
D. Hypernatremia
Answer: C
Conceptual Explanation: BNP is released by the ventricles in response to increased wall
tension or stretch, typically seen in volume overload or heart failure.
5. What is the hallmark finding in a patient diagnosed with Nephrotic Syndrome?
A. Proteinuria greater than 3.5g per day
B. Gross hematuria
C. Low serum cholesterol
D. Increased serum albumin
Answer: A
Conceptual Explanation: Nephrotic syndrome is defined by massive proteinuria
(>3.5g/24h), hypoalbuminemia, and edema.
6. A patient with Graves’ disease develops exophthalmos. This is caused by:
A. Increased intraocular pressure
