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 ["4.4"]

Explanation

To calculate the dosage of amoxicillin and clavulanate for the infant, we first convert the weight from pounds to kilograms, knowing that 1 pound is approximately 0.453592 kilograms. The infant weighs 16 pounds, which is roughly 7.25748 kilograms. The prescribed dose is 30 mg/kg/day, so for the infant, it would be 30 mg/kg/day * 7.25748 kg = 217.7244 mg/day. Since the medication is to be administered every 12 hours, the daily dose should be divided into two, resulting in 217.7244 mg/day / 2 = 108.8622 mg per dose. With the medication available in a concentration of 125 mg/5 mL, we calculate the volume per dose as (108.8622 mg * 5 mL) / 125 mg = 4.354488 mL per dose. Rounding to the nearest tenth, the nurse should administer 4.4 mL per dose.

Correct Answer is ["10"]

Explanation

To administer the correct dose of methylphenidate, which is 10 mg, when the available oral solution concentration is 5 mg per teaspoon, the nurse needs to calculate the volume to administer. One teaspoon is equivalent to 5 milliliters (mL). Since the desired dose is 10 mg, and the available solution has a concentration of 5 mg per teaspoon, the nurse would need two teaspoons to make up the 10 mg dose. Therefore, the nurse should administer 10 mL of the methylphenidate oral solution.
