He is admitted to the hospital and diagnosed with schizoaffective disorder. A review of medical records reveals a history of illicit drug use, particularly cocaine and amphetamines. He is started on aripiprazole, paroxetine, and trazodone. At the time of discharge, he appeared more coherent and with a marked improvement in positive symptoms of hallucinations and delusions but still with a flat effect. During the patients first follow-up visit, his mother reports he has become increasingly agitated and restless despite compliance with his medications. She reports that her sons hallucinations and delusions have stopped and he does not have suicidal ideations, but he cannot sit still and continuously taps his feet, wiggles his fingers, and paces in his room. When asked if anything is troubling him, he stands up and paces around the room. He says, I cannot sit still. Something is happening to me. A urine drug screen is negative. What is the next best step in the management of this patient?? A: Add lithium, B: Add propranolol, C: Increase the aripiprazole dose, D: Stop aripiprazole and switch to clozapine, E: Stop paroxetine,  <response>: This is a patient with schizoaffective disorder who was recently started on aripiprazole, paroxetine, and trazodone. He initially improved with treatment but now presents with agitation, restlessness, and an inability to sit still. This suggests the emergence of akathisia, which is a common side effect of antipsychotic medications like aripiprazole. The options include adding lithium or propranolol, which can help treat akathisia. Increasing the aripiprazole dose may worsen akathisia. Stopping paroxetine is unlikely to help as it is not known to cause akathisia. Stopping aripiprazole and switching to clozapine is an option but may not be necessary as the first step.B: Add propranolol
