A nurse is assessing a client who has heart failure and is taking digoxin. Which of the following manifestations should the nurse report to the provider as an indication of digoxin toxicity?

A. "Vomiting": Vomiting is a classic sign of digoxin toxicity. Other signs can include nausea, dizziness, confusion, and visual disturbances. If a client on digoxin exhibits vomiting, it should be reported immediately as it indicates possible toxicity. B. "Dilated pupils": Dilated pupils are not typically associated with digoxin toxicity. Pupillary changes are more commonly seen with other types of medications, such as anticholinergics, but not digoxin. C. "Bruising": Bruising is not a specific sign of digoxin toxicity. However, if a client on digoxin is also on anticoagulants, bruising could be a concern, but it is not directly related to digoxin itself. D. "Peripheral edema": Peripheral edema can occur in clients with heart failure as a symptom of fluid retention, but it is not indicative of digoxin toxicity. Digoxin toxicity typically presents with gastrointestinal and neurological symptoms, not edema.
