  1. A prescription for a pediatric patient reads 'Ibuprofen 10 mg/kg PO q6h PRN pain.' The child weighs 22 lbs. What is the correct dose?

    Answer: 100 mg

    22 lbs ÷ 2.2 = 10 kg; 10 kg × 10 mg/kg = 100 mg per dose.

  2. Which sig code instructs the patient to take medication every 8 hours?

    Answer: TID

    TID (ter in die) means three times daily, which equals every 8 hours when spaced evenly.

  3. A technician is preparing a 1:1000 epinephrine solution. How many mg of epinephrine are in 1 mL?

    Answer: 1 mg

    A 1:1000 ratio means 1 g per 1000 mL, which equals 1 mg per mL.

  4. A prescription reads 'Prednisone — taper: 40 mg QD × 3d, then 30 mg QD × 3d, then 20 mg QD × 3d, then 10 mg QD × 3d.' What is the total quantity of 10 mg tablets to dispense?

    Answer: 30 tablets

    In 10 mg tabs: 40mg=4 tabs × 3d=12, 30mg=3 tabs × 3d=9, 20mg=2 tabs × 3d=6, 10mg=1 tab × 3d=3; total = 12+9+6+3 = 30 tablets.

  5. An order reads 'Vancomycin 1 g IVPB q12h.' The drug is available as 500 mg powder vials. How many vials are needed per dose?

    Answer: 2 vials

    1 g = 1000 mg; 1000 mg ÷ 500 mg/vial = 2 vials per dose.

  6. The abbreviation 'DAW' on a prescription means the pharmacist must dispense:

    Answer: The brand-name drug as written

    DAW (Dispense As Written) instructs the pharmacy to dispense the exact brand-name drug ordered, without substituting a generic.

  7. A medication order reads 'Morphine 4 mg IV q4h PRN pain — max 3 doses in 12 hours.' What is the maximum 24-hour dose?

    Answer: 24 mg

    Max 3 doses per 12 hours × 2 periods = 6 doses per 24 hours; 6 × 4 mg = 24 mg maximum.
