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? - ANSWERRapidly 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...

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...
