Final answer:
To infuse Bretylium at a rate of 1mg/minute via IV infusion using 1 gram in 500 D5W, the rate of infusion per minute would be 2 mg/minute.
Step-by-step explanation:
The healthcare provider has ordered Bretylium to be infused at a rate of 1mg/minute via IV infusion. The available strength of the medication is 1 gram in 500 D5W. To calculate the rate of infusion per minute, we need to determine how many milligrams are in 1 gram.
Since there are 1000 milligrams in 1 gram, we have 1000 milligrams of Bretylium in 500 milliliters of D5W solution. Therefore, the rate of infusion per minute would be:
Rate of infusion = (1000 mg / 500 mL) x (1 mL / 1 minute) = 2 mg/minute
