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.)

Answer and Explanation

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 ["1.1"]

Explanation

To calculate the dosage of filgrastim, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 71 pounds, which is approximately 32.27 kilograms (71 lb / 2.2 kg/lb). Next, multiply the child's weight in kilograms by the dosage prescribed, which is 10 mcg/kg. This results in a total dosage of 322.7 mcg (32.27 kg * 10 mcg/kg). Finally, divide the total dosage needed by the concentration of the available medication to find out how many mL to administer. The filgrastim injection available is 300 mcg/mL, so you would administer approximately 1.08 mL (322.7 mcg / 300 mcg/mL), which rounds to 1.1 mL when rounded to the nearest tenth.

Correct Answer is ["1.9"]

Explanation

To calculate the dosage of cefotaxime, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 50 lb, which is approximately 22.7 kg (50 / 2.2). The prescribed dose is 100 mg/kg/day, so the total daily dose is 2,270 mg (100 mg/kg * 22.7 kg). This total daily dose should be divided into equal doses administered every 6 hours, which means 4 doses per day. Therefore, each dose will be 567.5 mg (2,270 mg / 4). With the medication available at a concentration of 300 mg/mL, divide the single dose by the concentration to find the volume per dose: 567.5 mg / 300 mg/mL = 1.89 mL. Rounded to the nearest tenth, the nurse should administer 1.9 mL per dose.
