During this period, she has also had urinary urgency and incontinence. Three months ago, she had blurry vision, difficulty distinguishing colors, and headache for one week, all of which have resolved. The patient has smoked a half pack of cigarettes daily for 10 years and drinks four glasses of wine each week. Her temperature is 37C 98.6F, pulse is 78min, respirations are 14min, and blood pressure is 11068 mm Hg. Examination shows 35 strength in the left arm and leg, and 55 strength on the right side. Upon flexion of the neck, the patient experiences a shooting electric sensation that travels down the spine. MRI of the brain shows gadolinium-enhancing lesions in the right central sulcus, cervical spinal cord, and optic nerve. Which of the following is the most appropriate next step in the management of this patient?? A: Administer lorazepam, B: Administer IV methylprednisolone, C: Plasmapheresis, D: Administer tissue plasminogen activator, E: Glatiramer acetate therapy,  <response>: This is a clinical vignette describing a 27-year-old woman with progressive numbness and weakness in her left arm and leg over 2 days, along with urinary urgency and incontinence. She also had an episode of neurological symptoms 3 months ago. She has some risk factors like smoking and alcohol use. On exam she has asymmetric weakness and experiences Lhermittes sign on neck flexion. MRI shows lesions typical for multiple sclerosis. This clinical presentation is most consistent with a multiple sclerosis exacerbation. The most appropriate next step is to treat the acute exacerbation with high-dose IV steroids. Lorazepam may help symptoms but does not treat the underlying disease process. Plasmapheresis may be used for severe attacks unresponsive to steroids. Tissue plasminogen activator is used for ischemic stroke, not MS exacerbations. Glatiramer acetate is a disease-modifying therapy to prevent MS relapses, not to treat acute attacks.B: Administer IV methylprednisolone
