A 38-year-old man with schizophrenia has been stable on clozapine 500 mg daily for 3 years with excellent symptom control. At today’s routine follow-up visit, his blood pressure is 148/94 mmHg. You check his chart and note his blood pressures over the past 6 months have been: 152/96, 146/92, 150/94, and 144/90 mmHg. He has no history of hypertension, diabetes, or cardiovascular disease. He reports no symptoms and denies chest pain, headaches, or visual changes. His BMI is 32 kg/m² (increased from 27 kg/m² when clozapine was initiated). He has not seen a primary care physician in 2 years.  It is appropriate to continue monitoring his blood pressure, since his psychiatric treatment is stable and adding medical referrals may compromise his engagement with mental health care.

A 38-year-old woman presents to your outpatient psychiatric clinic with a 4-month history of depressed mood, anhedonia, poor concentration, low energy, and hypersomnia. She reports sleeping 10-12 hours per night but never feeling rested. Her PHQ-9 score is 18 (moderately severe depression). She denies suicidal ideation. Her BMI is 34 kg/m². During the assessment, her husband, who accompanied her, volunteers that she snores loudly every night and he has noticed she stops breathing repeatedly during sleep, which frightens him. The patient confirms daytime sleepiness (Epworth Sleepiness Scale score of 16/24) and reports frequent morning headaches. She has no prior psychiatric history and medical history is significant only for hypertension managed with lisinopril 10 mg daily. She has not seen her primary care physician in over a year.  You suspect she may have undiagnosed obstructive sleep apnea (OSA) contributing to her depressive symptoms.   Which of the following is the MOST appropriate initial approach?
