NSG 5003 ADVANCED
PATHOPHYSIOLOGY FINAL EXAM
QUESTIONS WITH COMPLETE
SOLUTION GUARANTEED SUCCESS.
1. A patient with chronic kidney disease presents with severe anemia. Which deficiency is the
most likely cause?
A. Folate deficiency
B. Iron malabsorption
C. Lack of erythropoietin production
D. Vitamin B12 deficiency
Answer: C
Conceptual Explanation: The kidneys produce erythropoietin in response to hypoxia; in
chronic kidney disease, this production is impaired, leading to normocytic anemia.
2. Which mechanism best describes the pathophysiology of Type 1 Diabetes Mellitus?
A. Autoimmune destruction of pancreatic beta cells
B. Insulin resistance in peripheral tissues
C. Excessive glucagon secretion by alpha cells
D. Decreased glucose uptake by the liver
,Answer: A
Conceptual Explanation: Type 1 Diabetes is primarily an autoimmune disease where T-
cell mediated destruction of beta cells leads to absolute insulin deficiency.
3. In the Renin-Angiotensin-Aldosterone System (RAAS), what is the primary effect of
Angiotensin II?
A. Systemic vasoconstriction and aldosterone release
B. Decreased peripheral resistance
C. Vasodilation and sodium excretion
D. Inhibition of ADH secretion
Answer: A
Conceptual Explanation: Angiotensin II is a potent vasoconstrictor and stimulates the
adrenal cortex to release aldosterone, which increases blood pressure.
4. Which type of hypersensitivity reaction is mediated by IgE and involves mast cell
degranulation?
A. Type II
B. Type I
C. Type III
D. Type IV
Answer: B
, Conceptual Explanation: Type I hypersensitivity is an immediate allergic reaction
involving IgE antibodies binding to mast cells.
5. A patient presents with pulmonary edema due to left-sided heart failure. What is the
primary cause of the fluid shift into the alveoli?
A. Increased capillary oncotic pressure
B. Decreased capillary hydrostatic pressure
C. Increased capillary hydrostatic pressure
D. Decreased alveolar surface tension
Answer: C
Conceptual Explanation: Left heart failure causes blood to back up into the pulmonary
circulation, increasing capillary hydrostatic pressure and forcing fluid into the interstitial
space.
6. What is the characteristic cellular change observed in Barrett’s esophagus due to chronic
GERD?
A. Hypertrophy
B. Metaplasia
C. Atrophy
D. Dysplasia
Answer: B
