A 77-year-old male is admitted to the emergency department from a long-term care facility where he has lived for over 3 years. He has been maintained on antipsychotic medications for years but recently required a change to a first-generation agent as his symptoms were breaking through on even high doses of olanzapine. Last evening staff reported that he was increasingly confused, and this morning he developed a fever of 102.6o F. Initial laboratory assessment must include a: 

A. Urinalysis 

B. Complete blood count 

C. Creatine kinase 

D. Complete metabolic panel
