A nurse is administering prochlorperazine 0.13 mg/kg IM to a child who weighs 55 lb. Available is prochlorperazine injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.65"]
To calculate the dosage of prochlorperazine that the nurse should administer, we first convert the child's weight from pounds to kilograms, knowing that 1 kilogram is approximately 2.2 pounds. The child weighs 55 pounds, which is equivalent to 55 / 2.2 = 25 kilograms (rounded to the nearest whole number for simplicity). Next, we multiply the child's weight in kilograms by the dosage prescribed, which is 0.13 mg/kg. So, 25 kg * 0.13 mg/kg = 3.25 mg. Finally, since the available medication is 5 mg/mL, we divide the total milligrams needed by the concentration, resulting in 3.25 mg / 5 mg/mL = 0.65 mL. Therefore, the nurse should administer 0.65 mL, rounded to the nearest hundredth.

Correct Answer is ["2"]
Explanation
To calculate the dosage of haloperidol for the child, first determine the total daily dose by multiplying the child's weight by the prescribed amount per kilogram. For a child weighing 40 kg, this would be 0.15 mg/kg/day * 40 kg, which equals 6 mg/day. Since the medication is to be administered in divided doses every 8 hours, divide the total daily dose by the number of doses per day. There are 24 hours in a day, so with doses every 8 hours, that's 3 doses per day. Therefore, 6 mg/day divided by 3 doses per day equals 2 mg per dose.
Correct Answer is ["3"]
Explanation
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.
