Question Of The Day, Cardiovascular Disorders
Q. A nurse should monitor a client receiving lidocaine (Xylocaine) for toxicity. Which signs or symptoms in a client suggest lidocaine toxicity?

A. Nausea and vomiting
B. Pupillary changes
C. Confusion and restlessness
D. Hypertension



Correct Answer: C

Explanation: Confusion and restlessness are signs of lidocaine toxicity. Nausea and vomiting may occur with oral administration of mexiletine (Mexitil) or tocainide (Tonocard) — other class IB drugs. Pupillary changes and hypertension aren't signs of lidocaine toxicity, although visual changes and hypotension may occur as adverse reactions to class IB drugs.
