Answer to Question 1

C
The patient's behaviors of tongue rolling and lip smacking are symptoms of tardive dyskinesia associated with chlorpromazine therapy. This neurologic problem can become permanent if the patient remains on the drug long-term. Chlorpromazine is an older antipsychotic drug and the patient may respond better to a newer one. Although stopping the drug quickly can cause nausea, vomiting, and dizziness, these effects are not life threatening.

Answer to Question 2

A
All antipsychotic drugs tend to block dopamine receptors in the dopamine pathways in the brain. The normal effect of releasing the neurotransmitter dopamine is decreased. Transmission of im-pulses is decreased which in turn decreases the symptoms of hallucinations, illusions, and delu-sions.
