Answer to Question 1

ANS: B
The therapeutic range of digoxin is between 0.5 and 2 mg/mL. This patient's level is high, indicating toxicity. The nurse should not give the next dose or request a change in dose.

Answer to Question 2

ANS: D
Adenosine is a class III drug that prolongs repolarization by increasing the refractory period and prolonging the action potential to slow heart rate. It does not control atrial flutter, deepen myocardial excitability, or prevent multifocal contractions.
