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 ["0.6"]
Explanation
Identify the given information:
Dose of midazolam: 3 mg
Concentration of midazolam solution: 5 mg/mL
Calculate the volume of midazolam to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 3 mg / 5 mg/mL
Calculate the result:
Volume = 0.6 mL
Correct Answer is ["3.5"]
Explanation
Identify the given information:
Dose of digoxin: 7.5 mcg/kg/day
Weight of the child: 52 lb
Concentration of digoxin elixir: 50 mcg/mL
Convert the child's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total daily dose of digoxin in mcg:
Total daily dose = Dose/kg/day x Weight (kg)
Substitute the values:
Total daily dose = 7.5 mcg/kg/day x 52 lb x (0.453592 kg/1 lb)
Total daily dose ≈ 177.56 mcg
Calculate the dose per dose (every 24 hours):
Dose per dose = Total daily dose / 1
Substitute the values:
Dose per dose = 177.56 mcg / 1
Dose per dose ≈ 177.56 mcg
Calculate the volume of digoxin elixir to be administered:
Volume = Dose per dose (mcg) / Concentration (mcg/mL)
Substitute the values:
Volume = 177.56 mcg / 50 mcg/mL
Volume ≈ 3.55 mL
Round the answer to the nearest tenth:
Volume ≈ 3.5 mL
