Answer to Question 1

D
Quinidine is a class Ia antidysrhythmic drug that can slow the conduction of electrical impulses through the heart and lengthen the interval between the QRS complex and the T wave. This in-creases the patient's risk for development of an abnormal life-threatening ventricular rhythm called torsades de pointes, which can rapidly lead to ventricular fibrillation.

Answer to Question 2

D
Signs of digoxin overdose (toxicity) include nausea, vomiting, loss of appetite, diarrhea, and vi-sion problems. Other signs include heart rate or rhythm changes, palpitations, and fainting. When these signs and symptoms occur, hold the dose, notify the prescriber, and check the patient's se-rum digoxin level. This drug has a very narrow therapeutic range (0.8 to 2 ng/mL).
