Depression Pre-Treatment Assessment

The PMHNP is seeing a patient who presents for complaint of depressive symptoms. The patient reports a history of anhedonia, hopelessness, worthlessness, sleep dysfunction, marked decrease in appetite with an unplanned 5 lb wt loss in the last month, and a marked inability to concentrate on necessary tasks. 

Before diagnosing the patient with major depressive disorder and beginning antidepressive therapy, the PMHNP should: 

A. Document a Patient Health Questionnaire-9 

B. Administer a Mood Disorder Questionnaire 

C. Refer the patient to cognitive behavioral therapy 

D. Order a TSH and a CBC to rule out physiologic causes
