  1. A dopamine drip is ordered at 5 mcg/kg/min for a 70 kg patient. The bag contains 400 mg in 250 mL. What is the infusion rate in mL/hr?

    Answer: 13.1 mL/hr

    5 mcg/kg/min × 70 kg = 350 mcg/min; 400 mg/250 mL = 1.6 mg/mL = 1600 mcg/mL; 350 mcg/min ÷ 1600 mcg/mL × 60 = 13.1 mL/hr.

  2. How many mL of sterile water are needed to reconstitute a 1 g vial of cefazolin to achieve a concentration of 100 mg/mL?

    Answer: 10 mL

    1 g = 1000 mg; 1000 mg ÷ 100 mg/mL = 10 mL.

  3. A TPN requires 60 mEq of magnesium sulfate. Magnesium sulfate is available as 50% (4 mEq/mL). How many mL are needed?

    Answer: 15 mL

    60 mEq ÷ 4 mEq/mL = 15 mL.

  4. An IV bag labeled '2 mg/mL' morphine must deliver 0.05 mg/kg/hr to a 60 kg patient. What rate in mL/hr is required?

    Answer: 1.5 mL/hr

    0.05 mg/kg/hr × 60 kg = 3 mg/hr; 3 mg/hr ÷ 2 mg/mL = 1.5 mL/hr.

  5. A 250 mL NS bag contains 500 mg of ciprofloxacin. After 100 mL has infused, how many mg of drug remain in the bag?

    Answer: 300 mg

    500 mg ÷ 250 mL = 2 mg/mL; 150 mL remain × 2 mg/mL = 300 mg.

  6. What volume of a 40 mEq/20 mL KCl vial should be added to a bag to deliver 20 mEq of potassium?

    Answer: 10 mL

    40 mEq/20 mL = 2 mEq/mL; 20 mEq ÷ 2 mEq/mL = 10 mL.

  7. A beyond-use date (BUD) policy allows 12 hours at room temperature for a sterile preparation. If compounding is completed at 09:30, what is the latest BUD time?

    Answer: 21:30

    09:30 + 12 hours = 21:30.
