Answer to Question 1

ANS: B
In patients with bipolar disorder, antipsychotic drugs are given to help control symptoms during severe manic episodes, even if psychotic symptoms are absent. The antipsychotic drugs usually are given in combination with a mood stabilizer.
The antipsychotic drug addresses the symptoms, not the duration, of the manic episode.
Antipsychotic medications do not affect valproic acid levels.
Antipsychotics are not the primary therapy for bipolar disorder.

Answer to Question 2

ANS: D
The lithium level is toxic, therefore the dose should be held and the prescriber notified.
The drug should not be administered as prescribed, because it will increase the toxicity.
The dose is not subtherapeutic; rather, the patient's lithium level indicates toxicity.
It is up to the prescriber to change the dosage ordered. Changing the dosage without discussing it with the prescriber is a violation of the Nurse Practice Act, because nurses do not prescribe.
