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 ["5.7"]
Explanation
Identify the given information:
Dose of amoxicillin and clavulanate potassium: 40 mg/kg/day
Weight of the toddler: 25 lb
Concentration of amoxicillin and clavulanate potassium suspension: 200 mg/5 mL
Convert the toddler's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total daily dose of amoxicillin and clavulanate potassium in mg:
Total daily dose = Dose/kg/day x Weight (kg)
Substitute the values:
Total daily dose = 40 mg/kg/day x 25 lb x (0.453592 kg/1 lb)
Calculate the result:
Total daily dose ≈ 453.59 mg
Calculate the dose per dose (every 12 hours):
Dose per dose = Total daily dose / 2
Substitute the values:
Dose per dose = 453.59 mg / 2
Calculate the result:
Dose per dose ≈ 226.8 mg
Calculate the volume of amoxicillin and clavulanate potassium suspension to be administered:
Volume = Dose per dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 226.8 mg / (200 mg/5 mL)
Calculate the result:
Volume ≈ 5.67 mL
Round the answer to the nearest tenth:
Volume ≈ 5.7 mL
Correct Answer is ["0.4"]
Explanation
Identify the given information:
Dose of ferrous fumarate: 3 mg/kg/day
Weight of the toddler: 22 lb
Concentration of ferrous fumarate drops: 45 mg/0.6 mL
Convert the toddler's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total daily dose of ferrous fumarate in mg:
Total daily dose = Dose/kg/day x Weight (kg)
Substitute the values:
Total daily dose = 3 mg/kg/day x 22 lb x (0.453592 kg/1 lb)
Total daily dose ≈ 29.97 mg
Calculate the dose per dose (every 8 hours):
Dose per dose = Total daily dose / 3
Substitute the values:
Dose per dose = 29.97 mg / 3
Dose per dose ≈ 9.99 mg
Calculate the volume of ferrous fumarate drops to be administered:
Volume = Dose per dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 9.99 mg / (45 mg/0.6 mL)
Volume ≈ 0.133 mL
Round the answer to the nearest tenth:
Volume ≈ 0.1 mL
