SECTION I: ADVANCED CELLULAR PATHOPHYSIOLOGY (Questions 1–6)
Q1 (NR507-Final-01). A patient with chronic hepatitis C develops cirrhosis. Over time, the patient develops
hepatocellular carcinoma. The transformation from cirrhosis to cancer represents:
A) Malignant transformation (carcinogenesis) in the setting of chronic inflammation
B) Metaplasia of hepatocytes into a different cell type
C) Hyperplasia of hepatocytes without atypia
D) Atrophy of hepatocytes leading to cancer
Answer: A
Rationale: Chronic inflammation (as in chronic hepatitis C) is a risk factor for cancer development. Repeated
cycles of cell injury, death, and regeneration increase the risk of genetic mutations that can lead to malignant
transformation (carcinogenesis).

Q2 (NR507-Final-02). A patient experiences a prolonged period of ischemia to the brain following a cardiac
arrest. The type of cell death seen in this scenario is:
A) Liquefactive necrosis
B) Coagulative necrosis
C) Caseous necrosis
D) Fat necrosis
Answer: A
Rationale: Liquefactive necrosis is the characteristic form of cell death in the brain following ischemic injury
(stroke, cardiac arrest). Dead brain tissue is digested by enzymes, forming a liquefied cavity. Coagulative
necrosis (B) occurs in solid organs (heart, kidney, liver).

Q3 (NR507-Final-03). A patient with chronic kidney disease develops secondary hyperparathyroidism. The
pathophysiology of secondary hyperparathyroidism in CKD involves:
A) Hyperphosphatemia and hypocalcemia stimulating PTH secretion
B) Hypophosphatemia and hypercalcemia suppressing PTH secretion
C) Increased vitamin D production
D) Decreased PTH receptor sensitivity

RATIONALES | PASS GUARANTEED - A+ GRADED
Answer: A
Rationale: In CKD, the kidneys cannot excrete phosphate (hyperphosphatemia) and cannot activate vitamin
D (decreased calcium absorption). Hyperphosphatemia and hypocalcemia stimulate the parathyroid glands to
secrete more PTH (secondary hyperparathyroidism).

Q4 (NR507-Final-04). A patient with a traumatic brain injury develops increased intracranial pressure (ICP)
due to cerebral edema. The type of cerebral edema most commonly seen in this setting is:
A) Vasogenic edema (due to blood-brain barrier disruption)
B) Cytotoxic edema (due to cellular swelling)
C) Interstitial edema (due to hydrocephalus)
D) Osmotic edema (due to hyponatremia)
Answer: B
Rationale: Traumatic brain injury causes cytotoxic edema, where cellular swelling (especially of neurons and
glial cells) occurs due to failure of ion pumps and accumulation of intracellular water. Vasogenic edema (A)
occurs with tumors, abscesses, and late stages of trauma.

Q5 (NR507-Final-05). A patient is diagnosed with wet (exudative) age-related macular degeneration (AMD).
The pathophysiology of wet AMD involves:
A) Abnormal blood vessel growth (choroidal neovascularization) beneath the macula
B) Atrophy of the retinal pigment epithelium (RPE)
C) Accumulation of drusen in the macula
D) Cataract formation in the lens
Answer: A
Rationale: Wet (exudative) AMD is characterized by abnormal growth of blood vessels (choroidal
neovascularization) beneath the macula. These vessels leak fluid and blood, causing rapid central vision loss.
Dry (atrophic) AMD (B and C) involves drusen accumulation and RPE atrophy.

Q6 (NR507-Final-06). A patient with a history of alcoholism is admitted with confusion, nystagmus, and
ataxia. Which vitamin deficiency is most likely?
A) Thiamine (B1) – Wernicke encephalopathy
B) Vitamin B12 – pernicious anemia
C) Folate – megaloblastic anemia
D) Niacin (B3) – pellagra
