A nurse is preparing to administer methy prednisolone 7 mg/kg/day IM in two divided doses to a school-age child who weighs 64 lb. Available is methyiprednisolone 20 mg/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 ["5.1"]
First, convert the child's weight from pounds to kilograms: 64 lb / 2.205 lb/kg = 29.02 kg
Calculate the total daily dose of methylprednisolone needed: 7 mg/kg x 29.02 kg = 203.14 mg
Calculate the dose per administration: 203.14 mg / 2 = 101.57 mg
Calculate the volume of methylprednisolone to administer per dose: 101.57 mg / 20 mg/mL = 5.0785 mL
Round to the nearest tenth: 5.0785 mL rounded to the nearest tenth is 5.1 mL.

Correct Answer is ["1"]
Explanation
Convert the client's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
146.7 lb = 146.7 lb / 2.205 lb/kg = 66.53 kg (rounded to two decimal places).
Determine the total dosage:
The client is prescribed 7.5 mg/kg of metronidazole.
The client weighs 66.53 kg.
The total dosage is 7.5 mg/kg x 66.53 kg = 498.975 mg.
Determine the number of tablets per dose:
Each tablet contains 500 mg of metronidazole.
The nurse needs to administer 498.975 mg per dose.
To find the number of tablets per dose, we can set up a proportion:
500 mg / 1 tablet = 498.975 mg / x tablets
Cross-multiplying gives us:
500x = 498.975
Dividing both sides by 500, we get:
x = 0.99795 tablets
Round the answer to the nearest whole number:
Rounding 0.99795 to the nearest whole number gives us 1 tablet.
Correct Answer is ["3"]
Explanation
Determine the desired dosage:
The nurse needs to administer 120 mg of duloxetine.
Determine the number of capsules per dose:
Each capsule contains 40 mg of duloxetine.
The nurse needs to administer 120 mg per dose.
To find the number of capsules per dose:
40 mg / 1 capsule = 120 mg / x capsules
Cross-multiplying gives us:
40x = 120
Dividing both sides by 40, we get:
x = 3 capsules
