Practice Question

A nurse is preparing to administer quinine 25 mg/kg/day PO divided in equal doses every 8 hr to a school-age child who weighs 36 lb. Available is quinine 325 mg tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer Choices:

Rationale:

Formula:

Dose = (Weight in kg × Dose per kg) ÷ Number of doses/day

Given:

🔻Weight = 36 lb → 16.36 kg

🔻Dose = 25 mg/kg/day divided q8hr → 3 doses

🔻 Tablet = 325 mg

Calculation:

🔻Total dose/day = 16.36 × 25 = 409 mg

🔻 Dose per dose = 409 ÷ 3 = 136.33 mg

🔻 Tablets = 136.33 ÷ 325 = 0.42

→ 0 tablets
