The patient’s current weight is 75 pounds. The 500 mg of amoxicillin is contained in a 100 mL bag of normal saline and is to be infused over 1.5 hours. Calculate the safe “single dose range” for each 8 hour dose (mg/dose). Round to the nearest tenth or hundredth if needed. bd If the ordered dose is safe, at what rate will the RN set the electronic infusion device in milliliters per hour? Round answer to the whole number.
