ANSWERS (CHAMBERLAIN) 100%
GUARANTEE PASS
1. Which cellular process involves the activation of caspases resulting in programmed cell
death without triggering an inflammatory response?
A. Coagulative necrosis
B. Autophagy
C. Liquefactive necrosis
D. Apoptosis
Answer: D
Conceptual Explanation: Apoptosis is a highly regulated, programmed cell death process
that activates caspases and does not cause inflammation, unlike necrosis.
2. A 55-year-old male with chronic alcohol abuse presents with severe abdominal pain. Lab
results show elevated serum amylase and lipase. What is the primary pathophysiology of this
condition?
A. Bacterial infection of the gallbladder
B. Infection by Hepatitis B virus
,C. Obstruction of the common bile duct by a malignancy
D. Autodigestion of pancreatic tissue by prematurely activated enzymes
Answer: D
Conceptual Explanation: Pancreatitis involves the premature activation of pancreatic
enzymes (like trypsin) within the pancreas, leading to autodigestion of the gland.
3. Which of the following describes the mechanism by which ‘foam cells’ are formed in the
progression of atherosclerosis?
A. Platelets releasing growth factors in the intima
B. Smooth muscle cells migrating to the tunica media
C. Endothelial cells secreting nitric oxide
D. Macrophages engulfing oxidized LDL cholesterol
Answer: D
Conceptual Explanation: Foam cells are formed when macrophages ingest oxidized LDL
at the site of endothelial injury, forming the fatty streak in atherosclerosis.
4. In the context of cancer biology, what is the role of the p53 gene?
A. It acts as a proto-oncogene that stimulates cell growth
B. It facilitates angiogenesis via VEGF inhibition
C. It codes for growth factor receptors on the cell surface
, D. It is a tumor suppressor gene that monitors DNA integrity
Answer: D
Conceptual Explanation: p53 is a tumor suppressor gene known as the ‘guardian of the
genome’; it halts the cell cycle to repair DNA or induces apoptosis if damage is irreparable.
5. A patient with chronic kidney disease (CKD) develops secondary hyperparathyroidism.
What is the primary trigger for this compensatory mechanism?
A. Hypercalcemia and hypophosphatemia
B. Excessive secretion of renin by the juxtaglomerular apparatus
C. Increased production of erythropoietin
D. Hypocalcemia resulting from hyperphosphatemia and decreased Vitamin D activation
Answer: D
Conceptual Explanation: In CKD, phosphate retention and low active Vitamin D lead to
low serum calcium, which triggers the parathyroid glands to release PTH.
6. What is the primary pathophysiologic mechanism of Type 1 Diabetes Mellitus?
A. T-cell mediated autoimmune destruction of pancreatic beta cells
B. Insulin resistance in peripheral tissues
C. Excessive glucagon secretion by alpha cells
D. Destruction of islet cells by chronic pancreatitis
