A nurse is caring for a client who is taking digoxin. Which of the following findings should the nurse identify as an indication of digoxin toxicity?

A. Rash: A rash is not a typical manifestation of digoxin toxicity and is more often linked to allergic reactions or dermatologic conditions. While any new rash should be assessed, it does not specifically signal excessive digoxin levels. B. Dyspnea: Shortness of breath can occur in many cardiac or pulmonary conditions, especially heart failure, but it is not a primary indicator of digoxin toxicity. Dyspnea alone does not reliably reflect rising digoxin concentrations. C. Polyuria: Increased urine output is usually associated with diuretic use or endocrine disorders rather than digoxin. Digoxin does not stimulate urine production, so polyuria would not indicate toxicity. D. Bradycardia: Digoxin slows conduction through the AV node, and excessive levels can significantly depress heart rate. A notable drop in pulse can signal toxicity and requires immediate intervention to prevent dangerous arrhythmias.
