  1. An IV infusion of 1000 mL must be administered evenly over 8 hours. What is the required flow rate in mL/hour?

    Answer: 125 mL/hr

    Flow rate = 1000 mL ÷ 8 hours = 125 mL/hour.

  2. A child weighing 20 kg needs 10 mg/kg of ibuprofen. The available suspension contains 100 mg/5 mL. What volume is required per dose?

    Answer: 10 mL

    Required dose: 20 kg × 10 mg/kg = 200 mg; volume: (200 ÷ 100) × 5 = 10 mL.

  3. An IV infusion set delivers 20 drops/mL. The prescribed rate is 150 mL/hour. What is the required drip rate in drops per minute?

    Answer: 50 drops/min

    Drip rate = (150 mL/hr × 20 drops/mL) ÷ 60 min = 50 drops/min.

  4. A dobutamine infusion is prescribed at 2 mcg/kg/min for a 70 kg patient. What is the total infusion rate in mcg/min?

    Answer: 140 mcg/min

    Rate = 2 mcg/kg/min × 70 kg = 140 mcg/min.

  5. A pharmacist prepares 50 g of a 1% w/w ointment. How many grams of active drug are needed?

    Answer: 0.5 g

    1% w/w of 50 g = 0.01 × 50 = 0.5 g of active drug.

  6. A patient receives 15 mg of a drug three times daily. The maximum recommended daily dose is 60 mg/day. What percentage of the maximum dose is the patient receiving?

    Answer: 75%

    Daily dose = 15 mg × 3 = 45 mg; percentage = (45 ÷ 60) × 100 = 75%.

  7. An antibiotic vial contains 500 mg of powder. After reconstitution with water, the final volume is 10 mL. What is the final concentration in mg/mL?

    Answer: 50 mg/mL

    Concentration = 500 mg ÷ 10 mL = 50 mg/mL.
