Q1: A 58-year-old patient with a 40-pack-year smoking history is diagnosed with chronic
bronchitis. A bronchial biopsy reveals that the normal ciliated columnar epithelium has
been replaced by stratified squamous epithelium. What is the correct term for this
cellular adaptation?
A. Hyperplasia
B. Metaplasia [CORRECT]
C. Dysplasia
D. Anaplasia
Correct Answer: B
Rationale: The best answer is B because metaplasia is the reversible replacement of
one mature cell type by another, often as an adaptive response to chronic stress or
irritation like cigarette smoke, whereas hyperplasia is an increase in cell number.
Q2: A patient presents with severe crushing chest pain and is diagnosed with an
ST-elevation myocardial infarction. The myocardial cells in the affected territory swell,
lose their nuclei, and the tissue becomes intensely eosinophilic on microscopy. Which
specific type of cell death is occurring?
A. Apoptosis
B. Coagulative necrosis [CORRECT]
C. Liquefactive necrosis
D. Caseous necrosis
Correct Answer: B
Rationale: This choice is correct because the underlying pathophysiology of ischemic
injury in the heart typically leads to coagulative necrosis, where the basic tissue
architecture is preserved but the cells are dead, unlike liquefactive necrosis which is
typical of brain infarcts.
Q3: A graduate nursing student is reviewing lab results for a patient with a severe
bacterial infection and notes elevated levels of circulating tumor necrosis factor-alpha
,(TNF-alpha) and interleukin-1 (IL-1). Which systemic manifestation of inflammation is
most directly attributable to these specific chemical mediators?
A. Increased vascular permeability and edema
B. Fever and leukocytosis [CORRECT]
C. Pain and bradycardia
D. Cellular apoptosis
Correct Answer: B
Rationale: The best answer is B because TNF-alpha and IL-1 are endogenous
pyrogens that act on the hypothalamus to raise the temperature set point, and they also
stimulate the bone marrow to release leukocytes, whereas histamine is more directly
responsible for the initial vascular permeability.
Q4: A patient who suffered a deep partial-thickness burn to their arm is in the
proliferative phase of wound healing. The NP student observes red, granular tissue
forming in the wound bed. Which cellular component is most critical for producing the
extracellular matrix and collagen in this granulation tissue?
A. Macrophages
B. Fibroblasts [CORRECT]
C. Neutrophils
D. Keratinocytes
Correct Answer: B
Rationale: This matches the clinical reasoning framework taught in NURS 660 because
fibroblasts are the primary cells responsible for synthesizing and secreting collagen and
the extracellular matrix needed to rebuild the tissue framework during the proliferative
phase.
Q5: A 45-year-old patient presents with a large, raised, nodular scar on their chest
following a minor laceration. The scar tissue extends significantly beyond the
boundaries of the original wound. What is the underlying pathophysiologic mechanism
of this abnormal wound healing?
A. Excessive deposition of normal collagen by overactive fibroblasts [CORRECT]
B. Deficient collagen synthesis leading to tissue fragility
C. Replacement of normal tissue with cartilage
D. Uncontrolled proliferation of malignant squamous cells
Correct Answer: A
Rationale: The best answer is A because keloids, unlike normal scars, result from an
overexuberant healing response where fibroblasts continue to produce excessive
amounts of collagen, particularly type I, long after the wound has epithelialized.
Q6: A 28-year-old female patient is undergoing genetic counseling after her mother was
diagnosed with Huntington's disease. The patient's genetic test reveals she has one
, mutated allele with 42 CAG trinucleotide repeats. What is the most critical genetic
concept to explain to her regarding the potential severity of her disease?
A. Genetic anticipation, where an increased number of repeats in subsequent
generations can lead to earlier onset and more severe disease [CORRECT]
B. X-linked recessive inheritance, meaning her father must have been a carrier
C. Autosomal recessive inheritance, requiring two mutated alleles to express the
disease
D. Mitochondrial inheritance, meaning all of her children will definitely inherit the disease
Correct Answer: A
Rationale: This choice is correct because Huntington's disease is caused by a
trinucleotide repeat expansion, and larger repeat sizes (especially above 40) are
strongly correlated with genetic anticipation, a phenomenon where the disease
manifests earlier and more severely in the next generation.
Q7: A patient with a known BRCA1 gene mutation asks the NP to explain why this
mutation increases her risk for breast and ovarian cancer. What is the most accurate
cellular explanation?
A. BRCA1 is an oncogene that actively promotes rapid cell division when mutated.
B. BRCA1 normally acts as a tumor suppressor gene by repairing DNA double-strand
breaks, and its mutation leads to genomic instability. [CORRECT]
C. BRCA1 mutations directly cause viral DNA to integrate into the cellular genome.
D. BRCA1 is responsible for apoptosis, and the mutation prevents all cell death.
Correct Answer: B
Rationale: The best answer is B because the BRCA1 protein plays a vital role in the
homologous recombination repair of DNA double-strand breaks, and when it is mutated,
accumulated DNA errors go unrepaired, leading to the genomic instability that drives
carcinogenesis.
Q8: A patient is diagnosed with a high-grade, poorly differentiated adenocarcinoma of
the colon, and a CT scan shows metastases to the liver. How should the NP explain the
difference between the tumor grade and stage to the patient?
A. Grade refers to the size of the primary tumor, while stage refers to the number of
lymph nodes involved.
B. Grade describes the degree of cellular abnormality and loss of differentiation, while
stage describes the extent of spread of the cancer in the body. [CORRECT]
C. Grade indicates how fast the tumor responded to chemotherapy, while stage
indicates if the tumor is benign or malignant.
D. Grade and stage are interchangeable terms used by oncologists to determine the
exact chemotherapy dose.
Correct Answer: B
