Introduction
This document presents seventy-six (76) original, verified questions developed for
university-level nursing students working toward the midterm assessment of the
Nightingale College Pathophysiology course in the 2026/2027 cycle. The set is organized
into four domains: Cellular Processes, Genetics, and Fluid/Electrolyte Balance;
Inflammation, Immunity, and Infection; Hematologic, Cardiovascular, and Respiratory
Alterations; and Neurological, Endocrine, and Gastrointestinal Alterations. Each
question and its rationale is grounded in the official Nightingale College Pathophysiology
course materials, foundational pathophysiology texts such as McCance and Huether and
Porth, and current evidence-based medical standards, so students encounter the same
mechanistic, diagnostic, and clinical principles that appear on the actual exam. This
original content is designed to reinforce the official Nightingale College Pathophysiology
course objectives, strengthen clinical diagnostic and mechanistic mastery, and build the
professional competency expected of university-level nursing students in higher
education.
Domain: Cellular Processes, Genetics, and Fluid/Electrolyte
Balance
1. A weightlifter's skeletal muscle increases in size after months of heavy
resistance training. This cellular adaptation is best described as —
A. hyperplasia, an increase in the number of cells
B. metaplasia, a change from one mature cell type to another
C. hypertrophy, an increase in the size of existing cells in response to an increased
workload
D. dysplasia, a disorderly growth pattern with nuclear changes
Correct Answer: C
Rationale: Hypertrophy is an increase in the size of individual cells, which enlarges the
tissue or organ without increasing cell number. It occurs in muscle in response to
increased demand and in the heart with chronic pressure overload, and it is generally
reversible when the workload returns to normal. Hyperplasia, by contrast, increases
cell number and occurs in tissues capable of division.

,2. In response to chronic estrogen stimulation, the uterine endometrium
increases in cell number. This adaptation is best classified as —
A. hypertrophy, an increase in the size of existing cells
B. metaplasia, a change in cell type
C. hyperplasia, an increase in the number of cells that is often reversible when the
stimulus is removed
D. atrophy, a decrease in cell size
Correct Answer: C
Rationale: Hyperplasia is an increase in the number of cells in a tissue, typically in
response to hormonal or compensatory demands, and it is usually reversible when the
stimulus ends. Hormonal hyperplasia, as in the estrogen-stimulated endometrium,
differs from pathologic hyperplasia, which carries a greater risk of malignant
transformation.
3. A client confined to bed for several weeks develops decreased muscle
mass in the legs. This change is best explained as —
A. hypertrophy of the remaining muscle fibers
B. atrophy, a decrease in cell size resulting from reduced workload, innervation, or
blood supply
C. dysplasia of the muscle tissue
D. metaplasia of muscle to connective tissue
Correct Answer: B
Rationale: Atrophy is a decrease in cell size and tissue mass that follows reduced use,
loss of innervation, diminished blood supply, or inadequate nutrition. Disuse atrophy is
reversible with activity; other forms, such as denervation atrophy, may be permanent.
Cells that atrophy reduce their protein synthesis and increase protein breakdown.
4. In a long-term smoker, the normal ciliated columnar epithelium of the
bronchi is replaced by stratified squamous epithelium. This change is —
A. metaplasia, a reversible replacement of one mature cell type by another that is
better able to withstand the environment
B. dysplasia, a premalignant nuclear change
C. neoplasia, an irreversible malignant growth
D. apoptosis, a form of programmed cell death
Correct Answer: A
Rationale: Metaplasia is the reversible replacement of one adult cell type by another
adult cell type in response to chronic irritation or altered conditions, as when cigarette
smoke converts bronchial columnar epithelium to squamous epithelium. Metaplasia is
reversible if the stimulus is removed, although continued irritation can progress to
dysplasia and carcinoma.

, 5. Dysplastic cells are best characterized as cells that —
A. are identical to their normal counterparts in every way
B. show variation in size, shape, and nuclear organization and are considered a
preneoplastic change, though the change is not necessarily irreversible
C. have already metastasized to distant organs
D. are dead cells being removed by phagocytes
Correct Answer: B
Rationale: Dysplasia is a disorderly but nonneoplastic proliferation marked by
pleomorphism, hyperchromatic nuclei, and loss of normal architecture. It is a
preneoplastic change that ranges from mild to severe; severe dysplasia can progress to
carcinoma in situ, but the process remains reversible if the inciting stimulus is
removed.
6. Which statement about apoptosis is accurate?
A. It is an unregulated process that spills cellular contents into the surrounding
tissue
B. Apoptosis is programmed cell death executed by caspases, is energy dependent,
and does not typically trigger an inflammatory response
C. It always follows tissue necrosis in ischemic organs
D. It is initiated only by external physical injury
Correct Answer: B
Rationale: Apoptosis is an orderly, energy-requiring form of cell death carried out by
caspases through the intrinsic mitochondrial pathway or the extrinsic death-receptor
pathway. The cell fragments into apoptotic bodies that are cleared by phagocytes
without releasing contents, so inflammation does not occur; necrosis, by contrast, is
unregulated, spills contents, and provokes inflammation.
7. Coagulative necrosis is the characteristic pattern of cell death seen in —
A. tuberculosis, with a soft cheese-like center
B. the brain after a stroke
C. ischemic infarction of solid organs such as the heart, kidney, and spleen, where
protein denaturation preserves tissue architecture
D. acute pancreatitis with destruction of fat
Correct Answer: C
Rationale: Coagulative necrosis follows ischemia in most solid organs except the brain.
The cells die but the tissue architecture is preserved for a time because denatured
proteins resist digestion, leaving a firm, pale infarct that is later removed by
leukocytes. The brain undergoes liquefactive necrosis, tuberculosis produces caseous
necrosis, and the pancreas shows fat necrosis.
