Which of the following is a common sign of digoxin toxicity?

Nausea and vomiting are indeed common signs of digoxin toxicity. Digoxin, a medication used primarily for heart conditions, can lead to toxicity particularly when blood levels become elevated. The gastrointestinal symptoms, such as nausea and vomiting, often occur early in the presentation of digoxin toxicity and can serve as critical warning signs for both patients and healthcare providers. Recognizing these symptoms is vital because they may indicate that the patient requires immediate medical attention to prevent more severe complications, such as arrhythmias or even life-threatening situations.

Other options, while they may be symptoms of different conditions or issues, are not typically associated with digoxin toxicity. Excessive thirst may relate more to dehydration or diabetes, rapid weight gain could indicate fluid retention or other cardiac issues, and increased energy levels generally do not align with the effects of digoxin toxicity, making these options less relevant in this context. Understanding the specific signs of digoxin toxicity helps in timely identification and management, ultimately improving patient outcomes.
