Use a leading zero if it applies.
Do not use a trailing zero.). mL/hr.
The Correct Answer is ["150 mL\/hr"]
Step 1 is to determine the rate of infusion. This is done by dividing the total volume by the total time. So, we have 1200 mL ÷ 8 hr = 150 mL/hr.
So, the correct answer is 150 mL/hr.

Correct Answer is ["83 mL\/hr"]
Explanation
Step 1 is to calculate the total volume to be infused. The total volume is 1 L, which is equal to 1000 mL. Step 2 is to divide the total volume by the total time. The total time is 12 hours. So, the calculation is 1000 mL ÷ 12 hr = 83.33 mL/hr.
So, the correct answer is 83 mL/hr, after rounding to the nearest whole number.
Correct Answer is ["68 ml"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lb. So, the client’s weight in kg is 99 lb ÷ 2.2 = 45 kg (rounded to the nearest whole number). Step 2 is to calculate the total dosage of acetaminophen required. The prescribed dosage is 15 mg/kg, so the total dosage is 15 mg/kg × 45 kg = 675 mg. Step 3 is to calculate the volume to administer. The available medication is in a concentration of 1,000 mg/100 mL, which is the same as 10 mg/mL. So, the volume to administer is 675 mg ÷ 10 mg/mL = 67.5 mL. Rounding to the nearest whole number, the nurse should administer 68 mL.
So, the correct answer is 68 mL.
