WGU D027 Advanced Pathopharmacological
Foundations OA Practice Exam Questions
and Answers 2026. Advanced NCLEX-Style
100 MCQs with Rationales
Focusing on how disease processes, genetics, social determinants of health (SDOH), and
medications influence patient outcomes
1. A patient with heart failure is prescribed digoxin. Which
finding requires immediate intervention?
A. Apical pulse 58 bpm
B. Potassium 4.2 mEq/L
C. BP 130/80 mmHg
D. Respiratory rate 18/min
Answer: A
Rationale: Digoxin should be held if the apical pulse is below 60 bpm due to the risk of
bradycardia and toxicity.
2. Which electrolyte imbalance increases the risk of digoxin
toxicity?
A. Hypernatremia
B. Hyperkalemia
C. Hypokalemia
D. Hypercalcemia
Answer: C
Rationale: Low potassium enhances digoxin binding to myocardial cells, increasing toxicity
risk.

3. A patient with Type 2 diabetes has an HbA1c of 9.2%.
What does this indicate?
A. Excellent glycemic control
B. Poor glycemic control over the previous 2–3 months
C. Acute hyperglycemia only
D. Renal dysfunction
Answer: B
Rationale: HbA1c reflects average blood glucose over approximately 3 months.
4. Which hormone lowers blood glucose levels?
A. Cortisol
B. Glucagon
C. Epinephrine
D. Insulin
Answer: D
Rationale: Insulin facilitates glucose uptake into cells and lowers serum glucose.
5. Which assessment finding is most consistent with
hyperthyroidism?
A. Weight gain
B. Bradycardia
C. Heat intolerance
D. Constipation
Answer: C
Rationale: Increased metabolic activity causes heat intolerance, weight loss, and tachycardia.
6. Which finding is expected in hypothyroidism?
, WGU D027 Advanced Pathopharmacological Foundations
A. Tachycardia
B. Weight loss
C. Diarrhea
D. Fatigue
Answer: D
Rationale: Decreased metabolism causes fatigue, weight gain, and cold intolerance.
7. What is the primary pathophysiological problem in Type
1 diabetes?
A. Insulin resistance
B. Autoimmune destruction of beta cells
C. Excess glucagon
D. Obesity
Answer: B
Rationale: Type 1 diabetes results from autoimmune destruction of pancreatic beta cells.
8. A patient with COPD demonstrates which acid-base
imbalance during an acute exacerbation?
A. Respiratory alkalosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Metabolic acidosis
Answer: C
Rationale: Carbon dioxide retention leads to respiratory acidosis.
9. Which medication class is first-line therapy for
hypertension in many patients?
