A 56 yr-old male is admitted to the ICU with a blood pressure of 225/135 and complains of a headache and nausea. He reports he ran out of blood pressure meds three days ago, but also appears to be confused to the date and situation. What is the most appropriate treatment approach? - Correct Answer-Rapidly lower the diastolic pressure to 100 with IV antihypertensive meds, then continue to gradually reduce the diastolic pressure to 85 with oral antihypertensive meds. The maximum initial decrease should be no more than 25% reduction from initial presenting value. Reducing the blood pressure too quickly can lead to cerebral edema or renal failure.
