A nurse is preparing to administer 250 mg of an antibiotic IM. Available is 3 g/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
Desired dose = 250 mg
Available concentration = 3 g/5 mL = 600 mg/5 mL = 120 mg/mL
Volume to administer = Desired dose / Concentration = 250 mg / 120 mg/mL = 2.08 mL
Rounded to the nearest tenth = 0.4 mL

Understanding the Problem
We need to administer 840 mL of enteral nutrition over 24 hours.
We need to calculate the infusion rate in mL/hr.
Calculations
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 840 mL / 24 hr = 35 mL/hr
The nurse should set the infusion pump to deliver 35 mL/hr.
Correct Answer is ["200"]
Explanation
Convert pounds to kilograms: 88 lb ÷ 2.2 lb/kg = 40 kg
Calculate the dose: 5 mg/kg X 40 kg = 200 mg
