Write answer in between .Q:A 49-year-old woman is brought to the emergency department for a severe, sudden-onset generalized headache that began while she was riding an exercise bike at home that morning. After quickly getting off the bike and lying down, she lost consciousness. She was unconscious for a period of one minute. When she regained consciousness, she had neck stiffness, nausea, and two episodes of vomiting. She has hypertension. She does not smoke or drink alcohol. Her current medications include chlorthalidone and a multivitamin. She is in severe distress. Her temperature is 37.3C 99.1F, pulse is 88min, respirations are 18min, and blood pressure is 169102 mm Hg. A CT scan of the head without contrast shows hyperdense material between the arachnoid mater and the pia mater. The patient is taken to the operating room for surgical clipping and transferred to the intensive care unit. Five days later, she has new-onset focal weakness of her left lower extremity. Her temperature is 37.1C 98.8F, pulse is 70min, respirations are 17min, and blood pressure is 14890 mm Hg. Strength is 35 in the left lower extremity and 55 in the right lower extremity. Which of the following would most likely have been able to prevent this patients condition?? A: Intravenous labetalol, B: Intravenous fresh frozen plasma, C: Intravenous sodium nitroprusside, D: Oral nimodipine, E: Oral aspirin and clopidogrel,  <response>: This is a clinical vignette describing a patient with a subarachnoid hemorrhage bleeding between the arachnoid mater and pia mater likely due to a ruptured cerebral aneurysm. The patient underwent surgical clipping to secure the aneurysm. However, she developed delayed neurological deficits 5 days later, indicative of vasospasm leading to cerebral ischemia. The correct preventative treatment for vasospasm and delayed neurological deficits after subarachnoid hemorrhage is calcium channel blockers like oral nimodipine. Intravenous medications like labetalol, nitroprusside, and FFP would not be appropriate preventative treatments. Antiplatelet agents like aspirin and clopidogrel do not have a role in prevention of vasospasm.D: Oral nimodipine
