The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?

  • A. Hyponatremia
  • B. Hypernatremia
  • C. Hyperkalemia
  • D. Hypokalemia
Correct Answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.
