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

Correct Answer is ["675"]
Explanation
Convert pounds to kilograms: 198 lb ÷ 2.2 lb/kg = 90 kg
Calculate the total daily dose: 15 mg/kg/day X 90 kg = 1350 mg/day
Calculate the dose per administration: 1350 mg/day ÷ 2 doses = 675 mg/dose
Correct Answer is ["167"]
Explanation
Convert pounds to kilograms: 245 lbs / 2.2 lbs/kg = 111.36 kg
Calculate the enoxaparin dose: 1.5 mg/kg X 111.36 kg = 167.04 mg
Round to the nearest whole number: 167 mg
Therefore, the nurse should administer 167 mg of enoxaparin per dose.
