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 ["850"]

Explanation

To convert grams to milligrams, the value in grams is multiplied by 1,000. Therefore, to administer magnesium hydroxide 0.85 g PO, the nurse should administer 850 mg. This is because 0.85 grams equals 850 milligrams. When rounding to the nearest whole number, the amount remains 850 mg, as it is already a whole number.

Correct Answer is ["83"]

Explanation

To calculate the infusion rate for an IV, you would divide the total volume of IV fluid (1,000 mL) by the time in hours over which the infusion is to run (12 hr). This calculation gives you the rate in mL/hr. So, for 1,000 mL of sodium chloride to be infused over 12 hours, the calculation is 1,000 divided by 12, which equals approximately 83.33 mL/hr. When rounding to the nearest whole number, the IV pump should be set to deliver 83 mL/hr.
