A patient is prescribed thiazide diuretics and digoxin concurrently. The nurse should educate the patient on the signs and symptoms of digoxin toxicity. Which of the following signs and symptoms would the nurse expect the patient to experience if digoxin toxicity occurs?

A. Hypertension, hypokalemia, hyperglycemia: While thiazide diuretics can cause hypokalemia, hypertension and hyperglycemia are not primary indicators of digoxin toxicity. These symptoms reflect metabolic or cardiovascular issues unrelated to digoxin toxicity. B. Headache, muscle weakness, joint pain: These are nonspecific symptoms and are not classic signs of digoxin toxicity. They may indicate other conditions but do not reliably signal digoxin overdose. C. Vision disturbances, nausea, vomiting, and confusion: Digoxin toxicity commonly presents with gastrointestinal symptoms (nausea, vomiting), neurological changes (confusion), and visual disturbances (blurred or yellow vision, halos). Monitoring for these signs is crucial, especially when hypokalemia from thiazide diuretics increases the risk of toxicity. D. Shortness of breath, chest pain, dizziness: These symptoms may indicate cardiac issues such as angina or arrhythmias but are not the hallmark signs of digoxin toxicity. While arrhythmias can occur, the classic early signs are GI, visual, and neurological.
