WGU D027 Objective Assessment
Review | Advanced
Pathopharmacological Foundations
Instructions: This review exam for WGU D027 Advanced Pathopharmacological Foundations
contains 40 multiple-choice questions, reflecting the typical objective assessment format for this
course based on standard Western Governors University (WGU) graduate nursing curricula.
Each question provides four answer choices (A–D), the correct answer, and a detailed rationale
explaining why the correct answer is right and why others are incorrect. Topics cover advanced
pathophysiology (cellular injury, inflammation, immunity, genetics, oncology) and pharmacology
(drug mechanisms, safe prescribing, pharmacokinetics, pharmacodynamics) relevant to
advanced nursing practice. Each question is worth 2.5 points (total 100 points). Use this for
study and review. Good luck!
Question 1
What is the primary pathophysiological mechanism of cellular injury in ischemia?
A. Reduced ATP production due to lack of oxygen
B. Excessive calcium influx into mitochondria
C. Accumulation of reactive oxygen species
D. Direct DNA damage
Correct Answer: A
Rationale: Ischemia reduces oxygen supply, impairing oxidative phosphorylation and decreasing
ATP production, leading to cellular dysfunction. Why correct: ATP depletion disrupts membrane
pumps and cellular processes, per pathophysiology principles. Why others are incorrect:
Calcium influx (B) is secondary; reactive oxygen species (C) occur post-reperfusion; DNA
damage (D) is not primary in ischemia.
Question 2
A patient with type 2 diabetes is prescribed metformin. What is its primary mechanism of action?
A. Decreases hepatic glucose production
, B. Increases insulin secretion
C. Inhibits intestinal glucose absorption
D. Enhances peripheral glucose uptake
Correct Answer: A
Rationale: Metformin reduces gluconeogenesis in the liver, lowering blood glucose levels, per
ADA guidelines. Why correct: Primary mechanism for type 2 diabetes management. Why
others are incorrect: Insulin secretion (B) is sulfonylureas; absorption (C) is acarbose; uptake
(D) is secondary.
Question 3
In rheumatoid arthritis, what is the primary pathophysiological process?
A. Autoimmune-mediated synovial inflammation
B. Cartilage degeneration
C. Calcium crystal deposition
D. Bacterial joint infection
Correct Answer: A
Rationale: Rheumatoid arthritis involves autoimmune attack on synovial tissue, causing
inflammation and joint damage, per ACR guidelines. Why correct: Core immune
pathophysiology. Why others are incorrect: Degeneration (B) is osteoarthritis; crystals (C) are
pseudogout; infection (D) is septic arthritis.
Question 4
Which adverse effect should a nurse monitor for in a patient taking lisinopril?
A. Dry cough
B. Hypoglycemia
C. Seizures
D. Weight gain
Correct Answer: A
Rationale: Lisinopril, an ACE inhibitor, causes dry cough due to bradykinin accumulation. Why
correct: Common side effect per pharmacology standards. Why others are incorrect:
Hypoglycemia (B) is sulfonylureas; seizures (C) are rare; weight gain (D) is not typical.
