Question 1 of 5
A nurse is preparing to administer rifampin 20 mg/kg/day PO in two divided doses to a client who weighs 132 lb and has tuberculosis. The amount available is rifampin 150 mg capsules. How many capsules 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.)
Correct Answer: 4 capsules
Rationale: Weight: 132 lb ÷ 2.2 = 59.9 kg. Daily dose: 20 mg/kg/day × 59.9 kg = 1198 mg. Per dose: 1198 mg ÷ 2 = 599 mg. Capsules: 599 mg ÷ 150 mg = 3.993, rounded to 4.
