NURS 6501 ADVANCED
PATHOPHYSIOLOGY FINAL EXAM
PREP QUESTIONS AND ANSWERS
1. A patient presents with a widening pulse pressure, bradycardia, and irregular respirations.
These symptoms are characteristic of which clinical phenomenon?
A. Virchow’s Triad
B. Beck’s Triad
C. Cushing’s Triad
D. Whipple’s Triad
Answer: C
Conceptual Explanation: Cushing’s Triad (increased systolic BP/widened pulse pressure,
bradycardia, and irregular respirations) is a clinical sign of increased intracranial pressure.
2. Which mechanism is primarily responsible for the development of Type 1 Diabetes
Mellitus?
A. Insulin resistance in peripheral tissues
B. Hypersecretion of glucagon by alpha cells
,C. Autoimmune destruction of pancreatic beta cells
D. Decreased glucose uptake by the liver
Answer: C
Conceptual Explanation: Type 1 Diabetes involves a T-cell mediated autoimmune
destruction of the beta cells in the pancreas, leading to absolute insulin deficiency.
3. In the Renin-Angiotensin-Aldosterone System (RAAS), which enzyme is responsible for
converting Angiotensin I to Angiotensin II?
A. Renin
B. Angiotensin-Converting Enzyme (ACE)
C. Erythropoietin
D. Aldosterone synthase
Answer: B
Conceptual Explanation: ACE, primarily found in the pulmonary capillaries, converts
Angiotensin I into the potent vasoconstrictor Angiotensin II.
4. A patient with chronic kidney disease (CKD) develops anemia. What is the most likely
pathophysiological cause?
A. Decreased production of erythropoietin
B. Shortened life span of red blood cells
C. Iron deficiency due to poor diet
, D. Loss of blood during hemodialysis
Answer: A
Conceptual Explanation: The kidneys produce erythropoietin; in CKD, the reduction in
functional renal mass leads to decreased erythropoietin production, resulting in decreased
RBC synthesis.
5. Which type of hypersensitivity reaction is mediated by IgE and involves the release of
histamine from mast cells?
A. Type I
B. Type II
C. Type III
D. Type IV
Answer: A
Conceptual Explanation: Type I hypersensitivity is an immediate allergic reaction
mediated by IgE antibodies binding to mast cells.
6. What is the hallmark physiological finding in Acute Respiratory Distress Syndrome (ARDS)?
A. Increased pulmonary compliance
B. Decreased capillary permeability
C. Hypoventilation due to CNS depression
D. Non-cardiogenic pulmonary edema
