    Calculation

    A 5.6 kg patient is receiving digoxin by mouth every 8 hours. The safe dose is 0.03-10.06 mg/kg/day. What is the maximum safe dose for this patient? (Round to the nearest hundredth.)

    mg

    Explanation & Rationale

    Given: Patient weight = 5.6 kg Digoxin safe dose = 0.03–0.06 mg/kg/day Step 1: Calculate the maximum daily dose Maximum dose = 0.06 mg/kg/day × 5.6 kg 0.06 × 5.6 = 0.336 mg/day Step 2: Round to the nearest hundredth 0.336 → 0.34 mg/day Step 3: Divide by the number of doses per day (every 8 hours → 3 times/day) Maximum single dose = 0.34 mg ÷ 3 0.34 ÷ 3 ≈ 0.1133 mg Rounded to the nearest hundredth → 0.11 mg per dose
