Final answer:
To deliver amikacin 500 mg by intermittent IV bolus, the nurse should set the IV pump to deliver 400 mL/hr.
Step-by-step explanation:
To calculate the mL/hr rate at which to set the IV pump, we need to consider the volume of amikacin and the time it will take to infuse. The nurse has 500 mg of amikacin in a 200 mL bag of D5W to be infused over 30 minutes. To determine the mL/hr rate, we can use the formula:
Rate (mL/hr) = Volume (mL) / Time (hours)
In this case, the volume is 200 mL and the time is 0.5 hours (30 minutes converted to hours). Therefore, the nurse should set the IV pump to deliver 400 mL/hr.
