A nurse is preparing to administer digoxin 30 mcg/kg/day PO divided in equal doses every 8 hr to a school-age child who weighs 38 lb. Available is digoxin elixir 0.05 mg/mL. How many mL 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.)
The Correct Answer is ["3"]
To calculate the dosage of digoxin for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 38 pounds, which is approximately 17.27 kilograms (38 / 2.2 = 17.27). Next, calculate the total daily dose in micrograms by multiplying the child's weight in kilograms by the prescribed dose (17.27 kg * 30 mcg/kg/day = 518.1 mcg/day). Since the dose is divided into three equal parts to be given every 8 hours, divide the total daily dose by 3 (518.1 mcg/day / 3 = 172.7 mcg/dose). Now, convert the dose from micrograms to milligrams (172.7 mcg/dose * 0.001 = 0.1727 mg/dose). Finally, to find out how many milliliters of digoxin elixir to administer per dose, divide the dose in milligrams by the concentration of the elixir (0.1727 mg/dose / 0.05 mg/mL = 3.454 mL/dose). Rounding to the nearest whole number, the nurse should administer 3 mL per dose.

Explanation
To calculate the dosage of quinine for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 36 pounds, which is approximately 16.36 kilograms (36/2.2). Next, calculate the total daily dose of quinine using the child's weight in kilograms: 25 mg/kg/day * 16.36 kg = 409 mg/day. Since the dose is divided into equal doses every 8 hours, divide the total daily dose by 3 to get the per dose amount: 409 mg/day / 3 doses/day = approximately 136.33 mg/dose. Finally, to find out how many 325 mg tablets the nurse should administer per dose, divide the per dose amount by the strength of the tablet: 136.33 mg/dose / 325 mg/tablet = approximately 0.42. Rounding to the nearest whole number, the nurse should administer half a tablet per dose.
Correct Answer is ["50"]
Explanation
To calculate the IV pump setting, you would use the formula: Volume (mL) over Time (hr) = Rate (mL/hr). In this case, the total volume of the cefoxitin solution is 50 mL, and it needs to be administered over 1 hour. Therefore, the nurse should set the IV pump to deliver 50 mL/hr. When rounding to the nearest whole number, the rate remains 50 mL/hr.
