Final answer:
For an adult patient with bipolar I disorder mania with psychotic features, the nurse practitioner may prescribe quetiapine, as it manages psychosis and mood stability effectively (d). Other options like lithium and lamotrigine are mood stabilizers, while citalopram is generally for depression and not first-line for bipolar mania with psychotic features.
Step-by-step explanation:
According to current clinical guidelines for treating an adult patient with bipolar I disorder mania with psychotic features, an adult psychiatric and mental health nurse practitioner may prescribe quetiapine. Quetiapine is an antipsychotic medication that is used to manage both psychosis related to schizophrenia and the mood swings associated with bipolar disorder. It is preferred in cases of mania with psychotic features due to its effectiveness in managing both symptoms of psychosis and stabilizing mood.
In contrast to quetiapine, medications like lithium and lamotrigine are mood stabilizers and are commonly used to treat bipolar disorder but may not be as effective for acute psychotic symptoms. Citalopram, which is a selective serotonin reuptake inhibitor (SSRI), is generally prescribed for depression and is not the first-line treatment for bipolar mania with psychotic features.
It is important to note that the treatment of bipolar disorder often includes a combination of pharmacological interventions, such as neuroleptic drugs, mood stabilizers, and therapy. Treatment choices depend on several factors including the phase of the disorder, the patient's previous response to treatments, and the presence of any co-occurring mental or medical conditions.
