1. Which cellular process is characterized by programmed cell death that prevents an
inflammatory response, unlike necrosis?
A. Apoptosis
B. Autophagy
C. Oncosis
D. Hydropic degeneration
Answer: A
Conceptual Explanation: Apoptosis is an active, programmed process of cellular self-
destruction that does not cause inflammation, whereas necrosis involves swelling and
rupture of cells, spilling contents that trigger inflammatory responses.
2. In the Renin-Angiotensin-Aldosterone System (RAAS), which enzyme is responsible for
converting Angiotensin I to the potent vasoconstrictor Angiotensin II?
A. Renin
,B. Aldosterone synthase
C. Angiotensin-converting enzyme (ACE)
D. Aminopeptidase
Answer: C
Conceptual Explanation: ACE, primarily found in the pulmonary capillaries, catalyzes the
conversion of Angiotensin I to Angiotensin II.
3. A patient with Chronic Obstructive Pulmonary Disease (COPD) has a pH of 7.32, PaCO2 of
55 mmHg, and HCO3 of 28 mEq/L. Which acid-base imbalance is present?
A. Compensated Metabolic Alkalosis
B. Uncompensated Metabolic Acidosis
C. Partially Compensated Respiratory Alkalosis
D. Partially Compensated Respiratory Acidosis
Answer: D
Conceptual Explanation: The pH is low (acidosis), the PaCO2 is high (respiratory cause),
and the HCO3 is elevated, indicating the kidneys are attempting to compensate but have
not yet returned the pH to normal.
4. What is the primary pathophysiology behind Type 1 Diabetes Mellitus?
A. Insulin resistance in peripheral tissues
B. Autoimmune destruction of pancreatic beta cells
, C. Excessive glucagon secretion by alpha cells
D. Downregulation of insulin receptors
Answer: B
Conceptual Explanation: Type 1 Diabetes is characterized by an autoimmune-mediated
destruction of the insulin-producing beta cells in the Islets of Langerhans, leading to
absolute insulin deficiency.
5. Which compensatory mechanism occurs in response to chronic hypoxia in patients with
chronic lung disease?
A. Systemic vasodilation
B. Decreased heart rate
C. Increased erythropoietin production
D. Reduced hemoglobin affinity
Answer: C
Conceptual Explanation: Chronic hypoxia stimulates the kidneys to produce
erythropoietin, which increases red blood cell production (polycythemia) to improve
oxygen-carrying capacity.
6. What is the hallmark finding in the pathophysiology of Alzheimer’s Disease?
A. Dopaminergic depletion in the substantia nigra
B. Accumulation of amyloid-beta plaques and tau tangles
