Section 1: Cellular & Genetic Foundations (Questions 1–15)
Q1. A 55-year-old male with chronic alcohol use disorder presents with muscle
wasting and decreased liver size. Histology shows decreased cell size with
preserved cell number. What type of cellular adaptation is described?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
Correct Answer: C. Atrophy [CORRECT]
Rationale: Atrophy is a decrease in cell size resulting in decreased organ size, with
preserved cell number. Chronic alcohol use causes hepatocyte atrophy due to
protein synthesis impairment and malnutrition. Option A (hypertrophy) is increased
cell size. Option B (hyperplasia) is increased cell number. Option D (metaplasia) is
replacement of one differentiated cell type with another. ANCC FNP competency:
cellular adaptation recognition based on histologic and clinical presentation per
Robbins Pathologic Basis of Disease.
Q2. A 45-year-old female with a 30 pack-year smoking history develops squamous
cell carcinoma of the lung. Bronchial biopsy shows replacement of normal ciliated
pseudostratified columnar epithelium with stratified squamous epithelium. What
cellular adaptation preceded the malignancy?
,A. Dysplasia
B. Metaplasia
C. Hyperplasia
D. Hypertrophy
Correct Answer: B. Metaplasia [CORRECT]
Rationale: Metaplasia is the reversible replacement of one differentiated cell type
with another, often in response to chronic irritation. Smoking-induced bronchial
metaplasia (columnar → squamous) is a classic example and can progress to
dysplasia and carcinoma. Option A (dysplasia) describes disordered epithelial growth
with nuclear atypia and would follow metaplasia. Option C (hyperplasia) is increased
cell number of the same cell type. Option D (hypertrophy) is increased cell size.
ANCC FNP competency: metaplasia as a precursor to dysplasia and malignancy in
chronic irritation per Robbins Pathologic Basis of Disease.
Q3. A 28-year-old female presents with a breast lump. Biopsy shows disordered
epithelial proliferation with nuclear pleomorphism, hyperchromasia, and loss of
polarity, but the basement membrane remains intact. What is the MOST likely
diagnosis?
A. Carcinoma in situ
B. Dysplasia
C. Hyperplasia
D. Metaplasia
Correct Answer: B. Dysplasia [CORRECT]
Rationale: Dysplasia is disordered epithelial growth characterized by nuclear
pleomorphism, hyperchromasia, loss of polarity, and increased mitotic activity, with
intact basement membrane (pre-invasive). This is distinct from carcinoma in situ
(Option A) which represents full-thickness dysplasia without invasion. Option C
(hyperplasia) shows increased cell number without atypia. Option D (metaplasia)
shows cell type replacement without atypia. ANCC FNP competency: dysplasia
histopathologic features and distinction from carcinoma in situ per Robbins
Pathologic Basis of Disease.
,Q4. A 60-year-old male with coronary artery disease suffers a myocardial
infarction. Histology of the infarcted area 3 days later shows neutrophilic
infiltration and coagulative necrosis. What is the mechanism of cell death in this
tissue?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Correct Answer: C. Coagulative necrosis [CORRECT]
Rationale: Coagulative necrosis is characteristic of ischemic injury in solid organs
(heart, kidney, spleen) due to denaturation of structural and enzymatic proteins,
preserving tissue architecture. The neutrophilic infiltrate at 3 days represents the
inflammatory response. Option A (liquefactive necrosis) occurs in brain ischemia and
bacterial infections due to enzymatic digestion. Option B (caseous necrosis) is seen in
tuberculosis. Option D (fat necrosis) occurs in acute pancreatitis and breast trauma.
ANCC FNP competency: necrosis type identification based on tissue and etiology per
Robbins Pathologic Basis of Disease.
Q5. A 35-year-old male presents with acute pancreatitis. CT shows peripancreatic
fat stranding with chalky white deposits. Histology shows shadowy outlines of
adipocytes with basophilic calcium deposits. What type of necrosis is present?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Fat necrosis
D. Caseous necrosis
Correct Answer: C. Fat necrosis [CORRECT]
Rationale: Fat necrosis occurs when lipases (activated in pancreatitis) hydrolyze
triglycerides into fatty acids, which combine with calcium to form insoluble calcium
soaps (chalky white deposits, basophilic on H&E). Option A (coagulative) is seen in
, ischemic solid organs. Option B (liquefactive) is seen in brain and infections. Option
D (caseous) is seen in TB. ANCC FNP competency: fat necrosis pathophysiology in
acute pancreatitis per Robbins Pathologic Basis of Disease.
Q6. A 25-year-old male presents with progressive chorea, psychiatric symptoms,
and dementia. Genetic testing reveals CAG trinucleotide repeat expansion in the
HTT gene on chromosome 4. What is the inheritance pattern?
A. Autosomal recessive
B. Autosomal dominant
C. X-linked recessive
D. Mitochondrial
Correct Answer: B. Autosomal dominant [CORRECT]
Rationale: Huntington's disease is autosomal dominant with anticipation (earlier
onset in successive generations due to trinucleotide repeat expansion during
gametogenesis). The CAG repeat in the HTT gene produces an expanded
polyglutamine tract causing neuronal toxicity. Option A is incorrect (CF, sickle cell).
Option C (hemophilia A, DMD). Option D (maternal inheritance, e.g., MELAS, MERRF).
ANCC FNP competency: trinucleotide repeat disorders and inheritance patterns per
medical genetics principles.
Q7. A 6-month-old male presents with recurrent bacterial infections, failure to
thrive, and absent tonsils. Laboratory studies show absent B cells and low
immunoglobulins. Genetic testing reveals a mutation in the BTK gene. What is the
inheritance pattern?
A. Autosomal dominant
B. Autosomal recessive
C. X-linked recessive
D. Mitochondrial
Correct Answer: C. X-linked recessive [CORRECT]
