A nurse in a pediatric clinic is providing teaching to the guardian of an infant who has a new prescription for digoxin. Which of the following manifestations should the nurse include as an indication of digoxin toxicity?

Rationale: Digoxin toxicity commonly presents with bradycardia due to its effect on the heart's electrical conduction system. This can lead to arrhythmias and cardiac arrest. Polyuria, diaphoresis, and jaundice are not typical manifestations of digoxin toxicity. Polyuria and diaphoresis are more commonly seen with conditions like diabetes or hyperthyroidism. Jaundice is not a typical sign of digoxin toxicity. In summary, bradycardia is the key indicator of digoxin toxicity, making choice C the correct answer.
