Final answer:
The nurse should set the infusion pump to deliver approximately 123 mL/hour for a patient weighing 157 lbs and receiving a dopamine dosage of 8 mcg/kg/minute.
Explanation:
To solve this question, we need to convert the weight of the patient from pounds to kilograms. There are 2.2 pounds in a kilogram, so the patient weight of 157 lbs is approximately 71.36 kg. Then, we need to calculate the rate at which the dopamine is infused for this patient, which is given as 8 mcg/kg/minute. Thus, the patient will receive approximately 570.88 mcg of dopamine per minute. As per the question, we have 0.7 grams or 700,000 mcg of dopamine in 250 mL of solution. Hence, each mL of solution contains 2800 mcg of dopamine. To find out how many mL of solution the patient receives per hour, you divide the total amount of dopamine the patient receives per hour (570.88 mcg/min x 60 min) by the amount of dopamine in each mL. Rounding to the nearest whole number, the infusion pump should be set to deliver approximately 123 mL/hour.
