Section A: Disease Process & Terminology
Q1: A 58-year-old male is diagnosed with lung cancer. The oncologist explains that the
tumor has spread from the lung to the liver and bone. Which term best describes this
spread?
A. Dysplasia
B. Agenesis
C. Metastasis [CORRECT]
D. Hyperplasia
Correct Answer: C
Rationale: Metastasis is the spread of cancer cells from the primary site to distant
organs. Dysplasia (A) refers to abnormal cell development; agenesis (B) is failure of an
organ to form; hyperplasia (D) is an increase in cell number.
Q2: A pathologist examines a biopsy and notes that the tumor cells appear
undifferentiated, with large, irregular nuclei and loss of normal tissue architecture.
Which term describes these cellular changes?
A. Hypertrophy
,B. Anaplasia [CORRECT]
C. Metaplasia
D. Atrophy
Correct Answer: B
Rationale: Anaplasia refers to the loss of cellular differentiation and organization
characteristic of malignant neoplasms. Hypertrophy (A) is increased cell size;
metaplasia (C) is replacement of one cell type with another; atrophy (D) is decreased
cell size.
Q3: A tumor of connective tissue origin is classified as grade III based on the degree of
anaplasia. Which type of neoplasm is this most likely to be?
A. Carcinoma
B. Sarcoma [CORRECT]
C. Lymphoma
D. Melanoma
Correct Answer: B
Rationale: Sarcomas are malignant neoplasms of mesenchymal (connective tissue)
origin. Carcinomas (A) arise from epithelial tissue; lymphomas (C) from lymphoid
tissue; melanomas (D) from melanocytes.
,Q4: A patient presents with fever, tachycardia, tachypnea, and altered mental status.
Blood cultures are positive for bacteria, and inflammatory markers are markedly
elevated. Which condition is most likely present?
A. Local infection
B. Sepsis [CORRECT]
C. Aseptic inflammation
D. Benign neoplasm
Correct Answer: B
Rationale: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host
response to infection, characterized by systemic inflammation, fever, and hemodynamic
changes. Local infection (A) is confined; aseptic inflammation (C) lacks infection;
benign neoplasm (D) does not cause this presentation.
Q5: A patient has had rheumatoid arthritis for 15 years, requiring continuous medication
management and experiencing periodic flares. Which classification best describes this
disease duration?
A. Acute
B. Chronic [CORRECT]
C. Idiopathic
D. Congenital
Correct Answer: B
, Rationale: Chronic conditions are long-lasting and persistent, typically exceeding six
months. Acute (A) has rapid onset and short duration; idiopathic (C) refers to unknown
cause; congenital (D) refers to conditions present at birth.
Q6: A newborn is born without a fully formed left kidney. Which term describes this
developmental failure?
A. Dysplasia
B. Agenesis [CORRECT]
C. Hyperplasia
D. Neoplasia
Correct Answer: B
Rationale: Agenesis is the failure of an organ or part to form during embryonic
development. Dysplasia (A) is abnormal tissue development; hyperplasia (C) is
increased cell number; neoplasia (D) is abnormal new growth.
Q7: A patient's skin biopsy shows abnormal adult cells that are disorganized but
confined to the epithelium. Which term best describes this finding?
A. Carcinoma in situ
B. Dysplasia [CORRECT]
C. Metastasis
D. Benign hypertrophy
