NRP 571 ADVANCED
PATHOPHYSIOLOGY FINAL EXAM
QUESTIONS AND ANSWERS | 2026/2027
UPDATE | 100% CORRECT
1. A 55-year-old patient with chronic hypertension presents with left ventricular hypertrophy.
Which cellular adaptation process is primarily responsible for this change?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
Answer: A
Conceptual Explanation: Hypertrophy is an increase in the size of cells in response to
mechanical load or stress, such as increased afterload in hypertension, whereas
hyperplasia involves an increase in cell number.
2. What is the primary pathophysiology behind the development of Type 1 Diabetes Mellitus?
A. Insulin resistance in peripheral tissues
B. Downregulation of insulin receptors
C. Excessive glucagon production by alpha cells
,D. Autoimmune destruction of pancreatic beta cells
Answer: D
Conceptual Explanation: Type 1 DM is characterized by an absolute insulin deficiency due
to T-cell mediated autoimmune destruction of the insulin-producing beta cells in the Islets
of Langerhans.
3. In the Renin-Angiotensin-Aldosterone System (RAAS), what is the direct effect of
Angiotensin II on the kidneys?
A. Dilation of the afferent arteriole
B. Inhibition of ADH secretion
C. Vasoconstriction of the efferent arteriole
D. Increased excretion of sodium
Answer: C
Conceptual Explanation: Angiotensin II preferentially constricts the efferent arteriole to
maintain glomerular filtration rate (GFR) in the setting of low renal perfusion pressure.
4. Which of the following is a characteristic finding in patients with Nephrotic Syndrome?
A. Proteinuria exceeding 3.5g/day
B. Hematuria and hypertension
C. Elevated serum albumin levels
D. Oliguria and azotemia
, Answer: A
Conceptual Explanation: Nephrotic syndrome is defined by massive proteinuria (>3.5
g/24h), hypoalbuminemia, edema, and hyperlipidemia due to increased glomerular
permeability.
5. A patient is diagnosed with Pernicious Anemia. What is the underlying cause of this
condition?
A. Chronic blood loss leading to iron deficiency
B. Lack of intrinsic factor for Vitamin B12 absorption
C. Folic acid deficiency due to malnutrition
D. Bone marrow suppression by viral infection
Answer: B
Conceptual Explanation: Pernicious anemia is a megaloblastic anemia caused by the lack
of intrinsic factor, usually due to autoimmune parietal cell destruction, leading to Vitamin
B12 malabsorption.
6. Which statement best describes the pathophysiology of Myasthenia Gravis?
A. Demyelination of the peripheral nervous system
B. Loss of dopamine-producing neurons in the substantia nigra
C. Degeneration of upper and lower motor neurons
D. Autoantibodies blocking acetylcholine receptors at the neuromuscular junction
