How does a patient with digitalis toxicity typically present?

  1. Diarrhea and hypertension

  2. Vomiting and bradycardia

  3. Shortness of breath and cyanosis

  4. Nausea and pale skin

The correct answer is: Vomiting and bradycardia

A patient with digitalis toxicity typically presents with symptoms that reflect the effects of the drug on the cardiovascular system and gastrointestinal disturbances. One of the hallmark signs of digitalis toxicity is bradycardia, which is a slower than normal heart rate. This occurs because digitalis increases vagal tone, which can lead to a decrease in heart rate. Additionally, gastrointestinal symptoms such as vomiting are also common with digitalis toxicity. These symptoms can arise due to the irritant effects of the drug on the gastrointestinal tract or as part of the body's response to the toxicity. The combination of vomiting and bradycardia is characteristic in cases of digitalis toxicity, making it important for healthcare providers to be vigilant and recognize these signs for timely intervention. Other options present symptoms that do not specifically indicate digitalis toxicity either by their nature or due to a lack of association with digitalis effects on the body.
