Which action is associated with the use of lidocaine in the management of digoxin toxicity?

A. Increasing the digoxin dose is inappropriate in digoxin toxicity, as it would worsen the condition and increase the risk of life-threatening arrhythmias. B. Anticoagulation therapy is not directly related to the management of digoxin toxicity and does not address the primary problem. C. Administering potassium supplements may be necessary if hypokalemia is present, but it is not the primary action associated with using lidocaine. D. Decreasing the digoxin dose is an important step in managing digoxin toxicity, particularly when arrhythmias occur. Lidocaine is used as an antiarrhythmic agent to treat ventricular arrhythmias caused by digoxin toxicity, and reducing digoxin helps prevent further toxicity while managing cardiac effects.
