N512 ADVANCED PATHOPHYSIOLOGY –
CELLULAR FUNCTION AND IMMUNITY
CASE STUDIES | TISSUE TYPES,
GENETIC DISORDERS, HSV-2 &
SYSTEMIC LUPUS ERYTHEMATOSUS (SLE)
| PRACTICE QUESTIONS 1–100 AND
ANSWERS | 2026/2027
Introduction
This original practice question bank supports revision for N512 Advanced
Pathophysiology, focusing on cellular function, tissue types, genetic disorders, herpes
simplex virus type 2 (HSV-2), and systemic lupus erythematosus (SLE). It
emphasizes mechanisms of disease, clinical manifestations, diagnostic reasoning,
immune responses, and the relationship between cellular changes and patient
symptoms.
The questions are designed for advanced-level study and use case-based scenarios to
encourage application of pathophysiological concepts rather than memorization alone.
Each question has four answer options, one best answer, and a rationale explaining
why the correct option is appropriate and why the alternatives are less suitable.
These are original study questions, not verified copies of Post University examination
or assignment questions. They are intended to support independent learning and
should be checked against your course materials, assigned readings, and instructor
guidance.

Questions 1–100
Section 1: Cellular Function and Injury
Q1. A patient with prolonged hypotension develops cellular swelling in several organs.
Which mechanism most directly explains this early cellular change?
A. Increased DNA replication B. Failure of ATP-dependent sodium-potassium pumps
C. Increased synthesis of extracellular collagen D. Accelerated antibody production
Rationale: B is correct because inadequate ATP impairs the sodium-potassium pump,
allowing sodium and water to accumulate inside cells. A does not explain the
immediate fluid shift. C concerns extracellular matrix production rather than acute
cellular swelling. D is an immune response and does not account for this mechanism.
Q2. A patient experiences a brief period of ischemia, followed by restoration of blood
flow. Which process can paradoxically worsen tissue injury after reperfusion?
A. Reduced formation of reactive oxygen species B. Complete suppression of
inflammation C. Generation of reactive oxygen species and inflammatory activation
D. Permanent inhibition of leukocyte activity
, 3
Rationale: C is correct because reperfusion can generate reactive oxygen species and
activate inflammatory pathways, contributing to membrane, protein, and DNA
damage. A describes the opposite process. B and D are incorrect because reperfusion
does not completely suppress inflammation or permanently inhibit leukocytes.
Q3. A biopsy reveals increased cell size in skeletal muscle following resistance
training. Which cellular adaptation is most likely present?
A. Hyperplasia B. Metaplasia C. Hypertrophy D. Dysplasia
Rationale: C is correct because hypertrophy involves enlargement of individual cells,
increasing tissue size. A is an increase in cell number. B is the replacement of one
differentiated cell type by another. D refers to disordered cellular growth and
maturation.
Q4. A patient with chronic irritation develops replacement of one mature epithelial
cell type by another better suited to the environment. Which adaptation does this
represent?
A. Apoptosis B. Metaplasia C. Necrosis D. Atrophy
Rationale: B is correct because metaplasia is a potentially reversible change from one
differentiated cell type to another. A is programmed cell death. C is uncontrolled cell
death associated with cellular injury. D is a reduction in cell size and often tissue mass.
Q5. A laboratory specimen shows cell shrinkage, chromatin condensation, and
formation of membrane-bound apoptotic bodies. Which process is most likely
occurring?
A. Apoptosis B. Coagulative necrosis C. Liquefactive necrosis D. Cellular edema
Rationale: A is correct because shrinkage, chromatin condensation, and apoptotic
bodies are characteristic of programmed cell death. B typically preserves tissue
architecture temporarily after cell death. C involves enzymatic digestion and tissue
liquefaction. D describes swelling rather than shrinkage.
Q6. A patient develops myocardial injury after prolonged coronary artery occlusion.
Which form of necrosis is typically associated with ischemic injury in most solid
organs?
A. Fat necrosis B. Caseous necrosis C. Coagulative necrosis D. Fibrinoid necrosis
Rationale: C is correct because ischemia in most solid organs typically causes
coagulative necrosis, in which tissue architecture is initially preserved. A is associated
with injury to adipose tissue, such as in pancreatitis. B is classically associated with
certain granulomatous infections. D is associated with immune-mediated or vascular
injury.
Q7. A patient with severe acute pancreatitis develops destruction of surrounding fat
tissue. Which pathological process is most likely responsible?
