A patient with bipolar disorder has frequent manic episodes alternating with depressive episodes
The prescriber orders risperidone (Risperdal) in addition to the lithium (Lithobid) that the patient is already taking. The patient asks the nurse why another drug is needed. The nurse will tell the patient that the risperidone is used to:
a. elevate mood during depressive episodes.
b. help control symptoms during manic episodes.
c. manage tremors associated with lithium use.
d. prevent recurrence of depressive episodes.
ANS: B
Risperidone is an antipsychotic often used in conjunction with lithium to help manage symptoms during manic episodes, regardless of whether psychotic symptoms occur. Risperidone does not elevate mood and is not used during depressive episodes. It is not used to counter side effects associated with lithium. It does not prevent recurrence of depressive episodes.
