Practice Question

The nurse is caring for a client prescribed digoxin for heart failure. The nurse is aware that which of the following are signs of digitalis toxicity? (Select all that apply.)

Answer Choices:

Correct Answer:

Visual disturbances such as yellow halos

Rationale:

✅ Visual disturbances such as yellow halos

🔷 One of the classic signs of digoxin toxicity is visual changes, particularly xanthopsia (seeing yellow or green halos around lights). Clients may also report blurred vision, double vision (diplopia), or overall visual impairment.

🔷 This occurs because digoxin affects the optic nerve and retinal processing, producing altered color perception.

🔷 Since this symptom is unique to digoxin toxicity, it is a very useful early clinical clue for nurses and providers to identify digitalis poisoning. Prompt recognition is critical to prevent worsening cardiac complications.

Anorexia and nausea

🔷 Gastrointestinal disturbances are often the earliest signs of digoxin toxicity. These include loss of appetite (anorexia), nausea, vomiting, and abdominal discomfort.

🔷 Such symptoms result from digoxin’s direct action on the chemoreceptor trigger zone and GI tract, which stimulates nausea and vomiting centers.

🔷 Because these signs may appear before dangerous cardiac dysrhythmias, they are important warning indicators that the nurse must recognize quickly. Early reporting allows intervention (such as checking serum digoxin levels and adjusting dosage).
