A 33-year-old African American woman presents to the office complaining of blurry vision and headache for the past 2 weeks. She states that she has not been feeling herself lately and also fell down once after a dizzy episode. Her medical history is remarkable for hypertension and pulmonary sarcoidosis treated with hydralazine and prednisone respectively. She had a recent bout of acute optic neuritis, requiring high-dose IV methylprednisolone. Her temperature is 37°C (98.6°F), the blood pressure is 112/76 mm Hg, the pulse is 78/min, and the respirations are 14/min. On examination, the patient is mildly disoriented. Head and neck examination reveals a soft, supple neck and a right-sided facial droop. There is 5/5 muscle strength in all extremities. VDRL test is negative. A head MRI is pending. What is the most appropriate next step in the management of this patient?
