A nurse is preparing to administer digoxin 12 mcg/kg/day PO to divide equally every 12 hr to a school-age child who weighs 66 lb. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["3.6"]

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 66 pounds, which is approximately 30 kilograms (66 ÷ 2.2). The prescribed dose is 12 micrograms per kilogram per day, which equals 360 micrograms per day (12 mcg × 30 kg). Since the dose is divided every 12 hours, the child should receive 180 micrograms every 12 hours. The digoxin elixir is available at a concentration of 0.05 mg/mL, which is the same as 50 micrograms per milliliter. To find out how many milliliters to administer per dose, divide the dose in micrograms by the concentration: 180 mcg ÷ 50 mcg/mL equals 3.6 mL.

Correct Answer is ["200"]

Explanation

To calculate the infusion rate in mL/hr for administering 1 g of ceftriaxone sodium in 100 mL of dextrose 5% in water over 30 minutes, you would use the formula: (Total Volume in mL / Time in hours) = Rate in mL/hr. Since the time frame is 30 minutes, you convert this to hours by dividing by 60, which is 0.5 hours. Therefore, the calculation is 100 mL / 0.5 hours = 200 mL/hr. Rounding to the nearest whole number, the nurse should set the pump to deliver 200 mL/hr.

A. Decreased respiratory rate B. Increased formula consumption C. Increased crying episodes D. Decreased heart rate
