A 22-year-old woman presents for follow-up and evaluation 2 weeks after the initiation of fluoxetine (Prozac) for a diagnosis of major depressive disorder. At this visit, the PMHNP observes that the client has an elevated mood, her affect is expansive, and she is more talkative. The client says she has plans to write a novel that she believes will "change the face of American politics as we know it." When questioned about her potentially manic symptoms, the client becomes defensive. "I know you think I'm bipolar just because my mom was." She refuses to complete a self-rated mania symptom assessment tool. To further evaluate this client for mania, which of the following assessment tools will the PMHNP use?

Choice A reason: The Observer-Rated Scale for Mania is designed for nonclinicians and caregivers to rate observed manic behaviors rather than being a structured, clinician-administered assessment. It is less suitable for precise clinical assessment by a PMHNP. Choice B reason: The Altman Self-Rating Mania Scale is a self-report tool that requires patient participation. In this scenario, the patient refuses to complete self-rated assessments, making this tool ineffective. Choice C reason: The Self-Report Manic Inventory is also a self-report measure, requiring patient cooperation to provide accurate symptom reporting. Refusal by the patient prevents its use. Choice D reason: The Young Mania Rating Scale (YMRS) is a clinician-administered tool widely used to assess the severity of manic symptoms. It combines direct clinician observation with patient input during the clinical interview. It evaluates mood, motor activity, speech, irritability, grandiosity, sleep, and insight, making it ideal for situations where the patient is unwilling to complete self-report measures.
