  1. A prescription calls for 250 mg of amoxicillin. The available suspension is 125 mg/5 mL. How many mL should be dispensed per dose?

    Answer: 10 mL

    250 mg ÷ 125 mg/5 mL = 10 mL per dose.

  2. A patient needs 1.5 g of a medication. The tablets available are 500 mg each. How many tablets are needed?

    Answer: 3 tablets

    1.5 g = 1500 mg; 1500 mg ÷ 500 mg/tablet = 3 tablets.

  3. A pharmacy technician needs to prepare 200 mL of a 2% solution. How many grams of solute are required?

    Answer: 4 g

    2% means 2 g per 100 mL, so 200 mL requires 4 g.

  4. If a drug costs $0.85 per tablet and the patient needs a 30-day supply of 2 tablets per day, what is the total drug cost?

    Answer: $51.00

    2 tablets/day × 30 days = 60 tablets; 60 × $0.85 = $51.00.

  5. A physician orders heparin 1,000 units/hr via IV infusion. The available bag contains 25,000 units in 250 mL. What is the infusion rate in mL/hr?

    Answer: 10 mL/hr

    Concentration = 25,000 units ÷ 250 mL = 100 units/mL; 1,000 units ÷ 100 units/mL = 10 mL/hr.

  6. A prescription requires 454 g of a 1% hydrocortisone cream. How many grams of hydrocortisone active ingredient are needed?

    Answer: 4.54 g

    1% of 454 g = 0.01 × 454 = 4.54 g of active ingredient.
