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 86 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:

Correct Answer:

1

Rationale:

Formula: Dose per dose = (mg/kg/day × weight in kg) ÷ number of doses

Tablets per dose = Dose per dose ÷ tablet strength

Given:

🔻 Weight = 86 lb = 39.1 kg

🔻 Daily dose = 25 mg/kg/day × 39.1 kg = 977.5 mg/day

🔻 Doses per day = 3 (every 8 hr)

🔻 Dose per 8 hr = 977.5 ÷ 3 = 325.8 mg

🔻 Tablet strength = 325 mg

Calculation:

🔻 Tablets per dose = 325.8 ÷ 325 = 1
