Write answer in between .Q:A 52-year-old woman is brought to the emergency department for a severe, sudden-onset headache, light-sensitivity, and neck stiffness that began 30 minutes ago. A CT scan of the head shows hyperdensity between the arachnoid mater and the pia mater. The patient undergoes an endovascular procedure. One week later, she falls as she is returning from the bathroom. Neurologic examination shows 35 strength in the right lower extremity and 55 in the left lower extremity. Treatment with which of the following drugs is most likely to have prevented the patients current condition?? A: Enalapril, B: Nimodipine, C: Fresh frozen plasma, D: Fosphenytoin, E: Nitroglycerin,  <response>: This is a clinical vignette describing a patient with signs and symptoms of subarachnoid hemorrhage, likely due to a ruptured cerebral aneurysm. She underwent an endovascular procedure, likely coil embolization of the ruptured aneurysm. One week later, she fell and now has a right lower extremity weakness, indicating a stroke. The question asks which medication could have prevented this stroke. Based on the scenario, the most likely cause of the delayed stroke is vasospasm of cerebral arteries, a common complication of subarachnoid hemorrhage. Vasospasm causes narrowing of arteries and decreased blood flow, leading to cerebral ischemia and stroke. Nimodipine is a calcium channel blocker that inhibits cerebral vasospasm and is routinely used to prevent this complication in subarachnoid hemorrhage patients. The other answer choices are medications used for other indications and would not prevent vasospasm.B: Nimodipine
