  1. A pediatric dose of ibuprofen is 10 mg/kg. The patient weighs 44 lbs. What is the correct dose in mg?

    Answer: 200 mg

    44 lbs ÷ 2.2 = 20 kg; 20 kg × 10 mg/kg = 200 mg.

  2. How many milliliters are in 2.5 liters?

    Answer: 2,500 mL

    1 liter = 1,000 mL, so 2.5 liters = 2,500 mL.

  3. A prescription reads: 'Take ii tabs tid × 10 days.' How many tablets should be dispensed?

    Answer: 60 tablets

    2 tablets × 3 times/day × 10 days = 60 tablets.

  4. What is the flow rate in gtt/min for 1,000 mL of NS to be infused over 8 hours using a 15 gtt/mL drip set?

    Answer: 31 gtt/min

    1,000 mL ÷ 480 min × 15 gtt/mL ≈ 31.25, rounded to 31 gtt/min.

  5. A compounding formula requires 30% of ingredient A and 70% of ingredient B. If making 120 g total, how many grams of ingredient A are needed?

    Answer: 36 g

    30% × 120 g = 0.30 × 120 = 36 g of ingredient A.

  6. Convert 98.6°F to Celsius.

    Answer: 37°C

    (98.6°F − 32) × 5/9 = 66.6 × 0.555 = 37°C.
