A nurse is preparing to administer phenytoin 100 mg oral suspension PO to a school-age child who has epilepsy. According to the medication label. What is the total dose of the container? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The Correct Answer is ["100"]
Identify the given information:
Concentration of phenytoin oral suspension: 100 mg/4 mL
Volume of the container: 4 mL
Calculate the total dose of phenytoin:
Total dose = Concentration (mg/mL) x Volume (mL)
Substitute the values:
Total dose = 100 mg/4 mL x 4 mL
Calculate the result:
Total dose = 100 mg

Correct Answer is ["3.9"]
Explanation
Step-by-Step Solution:
Convert the toddler's weight from pounds to kilograms.
1 pound= 0.453592 kilograms.
26 pounds = 26 x 0.453592 = 11.793592 kilograms.
Calculate the total daily dose of prednisolone.
The prescribed dose is 2 mg/kg/day.
The toddler weighs 11.793592 kg.
Total daily dose = 2 mg/kg/day x 11.793592 kg = 23.587184 mg/day.
Determine the dose per administration.
Total daily dose is divided into two equal doses (every 12 hours).
The dose per administration = 23.587184 mg/day / 2 = 11.793592 mg per dose.
Calculate the volume of prednisolone syrup to administer.
The available prednisolone syrup is 15 mg/5 ml.
To find the volume, we can set up a proportion:
15 mg / 5 ml = 11.793592 mg / x ml
Cross-multiplying:
15x = 5 x 11.793592
Solving for x:
x = (5 x 11.793592) / 15 = 3.931197 ml
Round the answer to the nearest tenth.
3.9 mL
