PATH 370 FINAL EXAM 2025 (ACTUAL EXAM) | ALL QUESTIONS
AND CORRECT ANSWERS | ALREADY GRADED A+ | VERIFIED
ANSWERS | 100% CORRECT GUARANTEE PASS
1.
Topic: Cellular Adaptation
Question: Which term describes an increase in cell size due to increased
workload?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B
Rationale: Hypertrophy = ↑ cell size, not number. Seen in muscle growth.
2.
Topic: Genetics
Question: Which type of genetic disorder results from a single-gene
mutation?
A. Multifactorial disorder
B. Chromosomal disorder
C. Mendelian disorder
D. Mitochondrial disorder
Correct Answer: C
Rationale: Mendelian (autosomal dominant/recessive, X-linked) caused by
mutations in a single gene.
3.

Topic: Inflammation
Question: Which chemical mediator is primarily responsible for pain in
acute inflammation?
A. Histamine
B. Bradykinin
C. Prostaglandins
D. Leukotrienes
Correct Answer: B
Rationale: Bradykinin → vasodilation + pain (via nerve endings).
4.
Topic: Immunology
Question: Which immunoglobulin is the first produced in an initial immune
response?
A. IgG
B. IgM
C. IgA
D. IgE
Correct Answer: B
Rationale: IgM is the first antibody produced → short-lived but effective in
early infection.
5.
Topic: Neoplasia
Question: Which hallmark of cancer involves the ability to form new blood
vessels?
A. Metastasis
B. Angiogenesis
C. Apoptosis
D. Immortalization
Correct Answer: B
,3|Page
Rationale: Tumors secrete VEGF to promote angiogenesis → sustains
growth.
6.
Topic: Cardiovascular Pathophysiology
Question: Atherosclerosis begins with which key process?
A. Smooth muscle proliferation
B. LDL cholesterol oxidation
C. Foam cell formation
D. Endothelial injury
Correct Answer: D
Rationale: Endothelial damage → LDL entry, inflammation, foam cells →
plaque formation.
7.
Topic: Respiratory Pathology
Question: Which condition is characterized by destruction of alveolar walls
and loss of elastic recoil?
A. Chronic bronchitis
B. Pulmonary fibrosis
C. Emphysema
D. Asthma
Correct Answer: C
Rationale: Emphysema = “pink puffer” with alveolar wall destruction and
hyperinflation.
8.
Topic: Renal Disorders
Question: Which lab finding is most consistent with nephrotic syndrome?
A. Hematuria
, 4|Page
B. Proteinuria >3.5 g/day
C. Pyuria
D. Azotemia
Correct Answer: B
Rationale: Nephrotic syndrome → heavy proteinuria, hypoalbuminemia,
edema, hyperlipidemia.
9.
Topic: Acid-Base Imbalance
Question: pH 7.28, PaCO₂ 55, HCO₃⁻ 25 indicates:
A. Metabolic acidosis
B. Respiratory acidosis
C. Metabolic alkalosis
D. Respiratory alkalosis
Correct Answer: B
Rationale: Low pH + high CO₂ = respiratory acidosis (hypoventilation).
10.
Topic: Endocrine Pathology
Question: Which is a classic symptom of diabetes insipidus?
A. Hypertension
B. Polyuria
C. Weight gain
D. Oliguria
Correct Answer: B
Rationale: DI = ↓ ADH → inability to concentrate urine → polyuria,
polydipsia.
