1. Psychopharmacology

2. Incorrect assumptions Patient is triaged as psychiatric, therefore patient is psychiatric. Patient has a history of psychiatric presentations, therefore this presentation is psychiatric. Patient is young, therefore this must be a functional disorder. Abnormal vital signs are due to mental/emotional state.
