Question 1 of 5
A nurse is preparing to administer phenobarbital 3 mg/kg/day PO in two divided doses to a client who weighs 145 lb. The amount available is phenobarbital 100 mg/tablet. 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.)
Correct Answer: 1
Rationale: 145 lb = 65.9 kg; 65.9 kg × 3 mg/kg/day = 197.7 mg/day; 197.7 mg ÷ 2 doses = 98.85 mg/dose; 98.85 mg ÷ 100 mg/tablet ≈ 1 tablet per dose.
