Advanced Pathophysiology 2026/2027
Practice Exam
60 Original Mechanism and Clinical-Application Questions with Detailed Rationales
Purpose and alignment
Designed for graduate nursing and advanced-practice pathophysiology review. Coverage follows common Fall
2026 course outcomes: cellular adaptation and injury, inflammation and immunity, genetics, fluids and acid-base
balance, neoplasia, and integrated system pathophysiology.
How to use
Complete the items before reviewing the highlighted answers. Study every rationale and repeat weak domains.
Use 48/60 (80%) as a B-level learning target, not as a prediction, institutional cutoff, or guarantee.
Integrity notice
Every question was newly written for practice. This document is not an actual, recalled, leaked, proprietary, official,
or school-issued examination and is not endorsed by any school, publisher, or testing organization.

, CELLULAR ADAPTATION
Question 1 of 60: A smoker’s bronchial epithelium changes from ciliated columnar to
stratified squamous cells. This is:
A. Metaplasia
B. Hypertrophy
C. Hyperplasia
D. Anaplasia
Correct answer: A - Metaplasia
Rationale: Metaplasia is a reversible substitution of one mature cell type for another better able to tolerate chronic stress.
CELLULAR ADAPTATION
Question 2 of 60: In chronic hypertension, left ventricular muscle cells enlarge without
dividing. This is:
A. Atrophy
B. Hypertrophy
C. Dysplasia
D. Metaplasia
Correct answer: B - Hypertrophy
Rationale: Cardiac myocytes primarily adapt to increased workload by increasing cell size.

, CELLULAR INJURY
Question 3 of 60: Which change is most characteristic of reversible cellular injury?
A. Nuclear fragmentation
B. Membrane rupture with enzyme leakage
C. Cellular swelling
D. Complete mitochondrial destruction
Correct answer: C - Cellular swelling
Rationale: ATP depletion impairs ion pumps, producing hydropic swelling before irreversible damage occurs.
CELLULAR INJURY
Question 4 of 60: Which mechanism most directly produces ischemic cell injury?
A. Excess glycogen synthesis
B. Increased protein translation
C. Enhanced sodium-pump activity
D. Reduced oxidative phosphorylation and ATP depletion
Correct answer: D - Reduced oxidative phosphorylation and ATP depletion
Rationale: Loss of oxygen limits mitochondrial ATP production, disrupts ion gradients, and promotes acidosis and swelling.

, CELL DEATH
Question 5 of 60: Apoptosis differs from necrosis because apoptosis typically:
A. Activates regulated cell-death pathways with minimal inflammation
B. Causes uncontrolled membrane rupture
C. Always follows infection
D. Produces extensive surrounding tissue injury
Correct answer: A - Activates regulated cell-death pathways with minimal inflammation
Rationale: Apoptosis packages cellular contents for removal and usually avoids the inflammatory spill seen in necrosis.
CELL DEATH
Question 6 of 60: A myocardial infarction most commonly causes which pattern of
necrosis?
A. Liquefactive necrosis
B. Coagulative necrosis
C. Caseous necrosis
D. Fat necrosis
Correct answer: B - Coagulative necrosis
Rationale: Ischemic injury in most solid organs preserves tissue architecture temporarily, producing coagulative necrosis.
