A nurse is preparing to administer acetaminophen 400 mg PO to an adolescent. Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["13"]

To calculate the dosage of acetaminophen liquid required, one must use the formula: (desired dose / available dose) x volume of available dose. For the adolescent who needs 400 mg of acetaminophen, and with the available acetaminophen liquid concentration of 160 mg per 5 mL, the calculation would be: (400 mg / 160 mg) x 5 mL. This simplifies to 2.5 x 5 mL, which equals 12.5 mL.

Answer: 13 mL (rounded off to the nearest whole number)

Correct Answer is ["30"]

Explanation

To calculate the dosage of dexamethasone in milliliters 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). According to the prescription, the child requires 0.2 mg of dexamethasone per kilogram per day. So, for a 30 kg child, the total daily dosage is 6 mg (30 kg * 0.2 mg/kg). This total daily dose should be divided into two doses, which means each dose will be 3 mg (6 mg / 2). Given that the available elixir concentration is 0.5 mg per 5 mL, to administer a 3 mg dose, the nurse would need 30 mL of the elixir (3 mg / 0.5 mg * 5 mL). Therefore, the nurse should administer 30 mL per dose.

Correct Answer is ["400"]

Explanation

To calculate the infusion rate in mL/hr, you can use the formula: (Total Volume in mL / Time in hours) x 60. For an infusion of 100 mL over 15 minutes, you would first convert the time to hours, which is 15 minutes divided by 60, equaling 0.25 hours. Then, you divide the total volume by the time in hours: 100 mL / 0.25 hours equals 400. Finally, multiply by 60 to convert to an hourly rate: 400 x 60 equals 24,000 mL/hr. However, this number needs to be rounded to the nearest whole number, without a trailing zero. Therefore, the IV pump should be set to deliver 400 mL/hr.
