WGU D027 NURS 5204 Advanced Pathopharmacological Foundations FA READINESS EXAM QUESTIONS & ANSWERS

1. Question : A patient with chronic heart failure is
prescribed digoxin. Which electrolyte imbalance should a
nurse monitor for, as it increases the risk of digoxin toxicity?
 - A) Hyperkalemia
 - B) Hypocalcemia
 - C) Hyponatremia
 - D) Hypokalemia
 Answer : D) Hypokalemia
 Rationale : Low potassium levels can increase the
effects of digoxin, potentially leading to toxicity. Monitoring
potassium levels helps prevent adverse outcomes.
2. Question : In patients with asthma, beta-2 agonists are
typically administered to:
 - A) Reduce inflammation in the airways.
 - B) Block beta-1 adrenergic receptors.
 - C) Stimulate beta-2 adrenergic receptors, causing
bronchodilation.
 - D) Inhibit leukotriene production.
 Answer : C) Stimulate beta-2 adrenergic receptors,
causing bronchodilation.
 Rationale : Beta-2 agonists target beta-2 receptors in
the bronchial smooth muscle, leading to relaxation and
bronchodilation.
3. Question : A patient with a history of renal impairment
is prescribed an ACE inhibitor. What is the primary reason
for advising cautious use of this medication in renal
impairment?
 - A) Risk of metabolic acidosis
