Introduction
The WGU D115 Advanced Pathophysiology Pre-Assessment Exam is designed to evaluate graduate-level nursing
knowledge of disease mechanisms, clinical manifestations, and diagnostic reasoning essential for advanced practice.
The assessment measures competency in cellular biology, genetics, immune function, and system-specific
,pathophysiology. Questions utilize multiple-choice and scenario-based formats to simulate real-world clinical decision-
making. Emphasis is placed on applying foundational pathophysiological principles to patient assessment and
management. This examination prepares candidates for the rigor of advanced practice nursing by testing critical
thinking, clinical judgment, and integration of complex scientific concepts into professional practice.
SECTION ONE: QUESTIONS 1–50
Question 1
A patient with chronic hypertension develops left ventricular hypertrophy. Which cellular adaptation explains this
finding?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
🟢 Correct Answer: B. Hypertrophy
🔴 Explanation: Cardiac muscle cells have limited proliferative capacity and respond to increased workload by
enlarging existing cells through enhanced protein synthesis, a process termed hypertrophy.
Question 2
,A smoker's bronchial epithelium undergoes replacement from columnar to squamous cells. Which term describes
this change?
A. Atrophy
B. Hyperplasia
C. Metaplasia
D. Neoplasia
🟢 Correct Answer: C. Metaplasia
🔴 Explanation: Metaplasia is the reversible substitution of one mature cell type with another better suited to
withstand chronic irritation, as seen when columnar epithelium becomes squamous in smokers.
Question 3
Which process represents programmed, energy-dependent cell death without inflammation?
A. Necrosis
B. Apoptosis
C. Gangrene
D. Coagulative necrosis
🟢 Correct Answer: B. Apoptosis
, 🔴 Explanation: Apoptosis is an ATP-dependent, genetically regulated process involving caspase activation and
apoptotic body formation, which avoids triggering an inflammatory response.
Question 4
Following myocardial infarction, infarcted heart tissue maintains structural outlines but cells are nonviable. Which
necrosis type is present?
A. Liquefactive necrosis
B. Fat necrosis
C. Coagulative necrosis
D. Caseous necrosis
🟢 Correct Answer: C. Coagulative necrosis
🔴 Explanation: Coagulative necrosis preserves tissue architecture for days because denatured proteins resist
proteolysis; it is characteristic of ischemic injury in solid organs like the heart.
Question 5
A patient with tuberculosis shows cheese-like necrotic lung material on imaging. This finding represents:
