WGU D236 Pathophysiology — Comprehensive Practice Exam
Exam Overview: This 200-question practice exam mirrors the WGU D236 Pathophysiology Objective
Assessment blueprint, covering cellular adaptation and injury, inflammation and immunity,
fluid/electrolyte/acid-base balance, genetics, neoplasia, and systemic pathophysiology across all
major body systems.
SECTION 1: CELLULAR ADAPTATION & INJURY (Questions 1–25)
QUESTION 1:
A 68-year-old patient who has been bedridden for three months following a hip fracture shows
significant muscle wasting in the unaffected leg. Which cellular adaptation best describes this
change?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Metaplasia
ANSWER:
B. Atrophy
RATIONALE:
Atrophy is a decrease in cell size and function due to reduced workload, disuse, or denervation. The
unaffected leg experienced disuse during bedrest, leading to muscle fiber shrinkage. Hypertrophy (A)
involves increased cell size from increased demand. Hyperplasia (C) involves increased cell number.
Metaplasia (D) is the replacement of one differentiated cell type with another .
QUESTION 2:
During cellular injury, which process directly results from ATP depletion causing sodium-potassium
pump failure?
A. Apoptosis
B. Cellular swelling
C. Necrosis
D. Autophagy
ANSWER:
B. Cellular swelling
RATIONALE:
ATP depletion impairs the Na⁺/K⁺ ATPase pump, causing sodium to accumulate intracellularly. Water
follows sodium osmotically, leading to cellular swelling (hydropic degeneration). Apoptosis (A) is
programmed cell death. Necrosis (C) is uncontrolled cell death that occurs after severe injury.
Autophagy (D) is a recycling process for damaged organelles .
