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?

Choice A rationaleVomiting is a common sign of digoxin toxicity, occurring due to its impact on the gastrointestinal system. Normal serum digoxin level ranges from 0.5 to 2 ng/mL, with toxicity often presenting at levels above 2 ng/mL.Choice B rationaleDilated pupils are not typically associated with digoxin toxicity. Instead, this symptom is more commonly linked to conditions involving increased intracranial pressure or certain drug intoxications, such as anticholinergic poisoning.Choice C rationaleBruising is not a specific indicator of digoxin toxicity. Bruising is more likely related to coagulopathy or platelet disorders rather than the effects of digoxin, which primarily affects the cardiovascular and gastrointestinal systems.Choice D rationalePeripheral edema is not indicative of digoxin toxicity. This symptom is often associated with chronic heart failure or other conditions causing fluid retention rather than digoxin's pharmacological effects.
