Answer to Question 1

D
With older adults, signs of confusion may indicate lidocaine toxicity. Older adults are more sen-sitive to the effects and side effects of this drug. Notify the prescriber immediately; the drug must be stopped and the patient started on another antidysrhythmic drug to prevent life-threatening dysrhythmias such as ventricular tachycardia. Once the drug is discontinued and metabolized, these symptoms will resolve.

Answer to Question 2

C
Lidocaine can only be given by IV or by airway inhalation (ET tube). When given orally, the liver destroys most of the drug, making it ineffective.
