answers and detailed explanations in italic.
This comprehensive study resource covers all essential topics from the WGU D236
Pathophysiology OA V2 exam :
✅ Cellular Injury & Adaptation – Reversible vs irreversible injury, apoptosis vs
necrosis, metaplasia, dysplasia, anaplasia, hyperplasia, hypertrophy, cellular adaptations
✅ Inflammation & Wound Healing – Acute vs chronic inflammation,
primary/secondary/tertiary intention healing, collagen synthesis, Vitamin C requirement,
keloids vs hypertrophic scars
✅ Genetics & Congenital Disorders – Autosomal dominant (Huntington, Marfan),
autosomal recessive (Cystic Fibrosis, Tay-Sachs, Sickle Cell), X-linked recessive
(Hemophilia), Turner Syndrome, neural tube defects
✅ Neoplasia & Cancer – Benign vs malignant tumors, tumor grade vs stage, p53 tumor
suppressor gene, metastasis pathways, dysplasia vs anaplasia
✅ Fluid & Electrolyte Imbalances – Hyperkalemia (K > 5.0: muscle weakness, paralysis,
cardiac dysrhythmias), hypocalcemia (Chvostek sign), Starling's Law, osmotic vs
hydrostatic pressure
, ✅ Cardiovascular Disorders – Myocardial infarction (coronary occlusion, elevated
troponin/CK-MB), right vs left-sided heart failure (JVD vs pulmonary edema), malignant
hypertension (>180/120, end-organ damage), angina pectoris, cor pulmonale
✅ Respiratory Disorders – COPD (smoking, asthma, dust, genetics), respiratory
acidosis (pH low, PaCO2 high), hypoxemia mechanisms
✅ Neurological Disorders – ALS (head drop), Multiple Sclerosis (CNS demyelination,
weakness), Parkinson's disease (resting tremor), Guillain-Barré, Myasthenia Gravis
✅ Renal Disorders – Acute Kidney Injury (AKI), glomerulonephritis, pyelonephritis, renal
calculi, End-Stage Renal Disease, GFR staging
✅ Gastrointestinal Disorders – Diverticulosis (pouch-like herniations, asymptomatic),
Ulcerative Colitis, Crohn's Disease, GERD (LES failure), colon cancer (left:
obstruction/pencil-thin stools; right: iron deficiency anemia)
✅ Endocrine & Hematologic Disorders – Type 1 (autoimmune) vs Type 2 (insulin
resistance) diabetes, Graves disease, hyper/hypothyroidism, aplastic anemia, DKA
150 practice questions organized by topic

Comprehensive answer key included
📚 Section 1: Cellular Injury, Inflammation & Wound Healing (Questions 1–25)
1. A patient presents with a clean surgical incision closed with sutures. This wound
is expected to heal by which intention?
, A) Secondary intention
B) Primary intention
C) Tertiary intention
D) Fibrosis only
Answer: B
Explanation: A clean surgical incision with approximated edges heals by primary intention,
which results in rapid healing with minimal scar formation and low infection risk . Secondary
intention is for open or contaminated wounds that heal by granulation. Tertiary intention
involves delayed closure after infection control.
2. Collagen synthesis in wound healing requires which vitamin as a cofactor for
hydroxylation?
A) Vitamin A
B) Vitamin B12
C) Vitamin C
D) Vitamin D
Answer: C
Explanation: Vitamin C is an essential cofactor for the hydroxylation of proline and lysine
during collagen synthesis. Deficiency impairs wound healing and increases capillary
fragility .
, 3. Which feature characterizes a BENIGN tumor?
A) Rapid growth with metastasis
B) Encapsulation and slow, expansive growth
C) Poor differentiation
D) Invasion of adjacent tissue
Answer: B
Explanation: Benign tumors are typically encapsulated, slow-growing, and remain localized.
They are well-differentiated and do not invade adjacent tissues or metastasize .
4. Loss of differentiation with pleomorphism and abnormal mitoses in a tumor is
termed:
A) Hyperplasia
B) Anaplasia
C) Metaplasia
D) Organization
Answer: B
Explanation: Anaplasia, meaning "backward formation," is the hallmark of malignancy. It is
characterized by loss of cellular differentiation, pleomorphism (variation in size and shape),
and abnormal mitotic figures .
