The patients boyfriend states that he came home from work and found the patient sitting up in bed staring at the wall. When he said her name or waved his hand in front of her, she did not respond. When he tried to move her, she would remain in whatever position she was placed. The patients temperature is 99F 37.2C, blood pressure is 12279 mmHg, pulse is 68min, and respirations are 12min with an oxygen saturation of 98 O2 on room air. During the physical exam, the patient is lying on the bed with her left arm raised and pointing at the ceiling. She resists any attempt to change her position. The patient remains mute and ignores any external stimuli. The patients medical history is significant for depression. She was recently switched from phenelzine to fluoxetine. Which of the following is the best initial therapy?? A: Benztropine, B: Cyproheptadine, C: Electroconvulsive therapy, D: Haloperidol, E: Lorazepam,  <response>: This appears to be a case of catatonic schizophrenia in a 23-year-old woman with a history of depression who was recently switched from phenelzine to fluoxetine. The description of her behavior, including mutism, posturing, waxy flexibility, and ignoring external stimuli, is classic for catatonia. The main initial treatment options for catatonia are benzodiazepines like lorazepam, antipsychotics like haloperidol, or electroconvulsive therapy ECT. Benztropine and cyproheptadine are anticholinergics sometimes used as adjunctive treatments but are not first-line. Lorazepam is usually the preferred initial treatment for catatonia as it is safer and acts rapidly compared to antipsychotics. Haloperidol would be another option but has a higher risk of adverse effects. ECT is highly effective but is not usually used as a first-line treatment.E: Lorazepam
