The patient has a past medical history of insulin-controlled diabetes, hypertension, and hyperlipidemia. He smokes 2 packs of cigarettes per day. He states that he forgot to take his medications yesterday and started getting a headache about one hour ago. His vitals on admission are the following: blood pressure of 160110 mmHg, pulse 95min, temperature 98.6 deg F 37.2 deg C, and respirations 20min. On exam, the patient has an audible abdominal bruit. After administration of antihypertensive medications, the patient has a blood pressure of 178120 mmHg. The patient reports his headache has increased to a 1010 pain level, that he has trouble seeing, and he cant move his extremities. After stabilizing the patient, what is the best next step to diagnose the patients condition?? A: CT head with intravenous contrast, B: CT head without intravenous contrast, C: MRI head with intravenous constrast, D: MRI head without intravenous constrast, E: Doppler ultrasound of the carotids,  <response>: This is a question about a 60-year-old male patient admitted to the ICU with severe hypertension and headache. The patient has a history of diabetes, hypertension, hyperlipidemia, and heavy smoking. He forgot to take his medications and developed a severe headache. On exam he has high blood pressure that did not improve much with medications, worsening headache, vision changes, and inability to move extremities. Based on the acute onset of neurological symptoms in the setting of uncontrolled hypertension, the most likely diagnosis is hypertensive encephalopathy. Imaging of the brain is needed to confirm this and evaluate for complications like hemorrhage or infarct. CT head is preferred over MRI in the acute setting because it is faster and more readily available. Contrast is not necessarily needed initially. Doppler ultrasound of the carotids would not provide enough information about the brain parenchyma in this scenario.B: CT head without intravenous contrast
