A nurse is preparing to administer amoxicillin and clavulanate potassium 40 mg/kg/day PO divided in equal doses every 12 hr to a toddler who weighs 25 lb. Available is amoxicillin and clavulanate potassium suspension 200 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["5.7"]
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 ["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
Correct Answer is ["3"]
Explanation
Identify the given information:
Dose of azithromycin: 10 mg/kg
Weight of the toddler: 27 lb
Concentration of azithromycin suspension: 200 mg/5 mL
Convert the toddler's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total dose of azithromycin in mg:
Total dose = Dose/kg x Weight (kg)
Substitute the values:
Total dose = 10 mg/kg x 27 lb x (0.453592 kg/1 lb)
Calculate the result:
Total dose ≈ 122.47 mg
Calculate the volume of azithromycin suspension to be administered:
Volume = Total dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 122.47 mg / (200 mg/5 mL)
Calculate the result:
Volume ≈ 3.06 mL
Round the answer to the nearest whole number:
Volume ≈ 3 mL
