A doctor orders IV Levaquin, 750 mg in 500 mL of D5W, for a patient with an infection. The IV set delivers 20 drops/mL and 75 mL/hr. How many milligrams of Levaquin will the patient receive in two hours?
  1. 45 mg
  2. 75 mg
  3. 122 mg
  4. 225 mg
Explanation
Answer: D - The patient will receive 225 mg of Levaquin in 2 hours. If the IV bag has 750 mg in 500 mL of solution, it has a concentration of 1.5 mg/mL. If the set is delivering 75 mL/hr, the patient will receive 150 mL in 2 hours, and 150 mL x 1.5 mg/mL = 225 mg Levaquin delivered in 2 hours.
