Exercise 63

A patient with malignant hypertension is being treated in the critical care unit. The physician writes the following order: Nipride 50 mg in 500 mL D5W to start at 1 mcg/kg/min, and titrate to maintain the systolic BP under 140. (When you measure a patient's blood pressure, the first number represents the systolic blood pressure.) The patient weighs 176 lb. According to the product insert, the maximum safe dose of Nipride is 10 mcg/kg/min.
What is the maximum safe rate for the infusion?
