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 A
Explanation
A. With "EP 116" stamped on one side of the tablet: The label specifies that the furosemide 20 mg medication is a "white round tablet" marked with "EP 116" on one side. This is how the nurse should expect the medication to appear before administering it to the client.
B. As a multicolored capsule: The medication described on the label is not in capsule form. Capsules are typically used for medications that require specific release mechanisms, which is not relevant for furosemide 20 mg in this scenario.
C. With "Furosemide 20 mg’’ printed on one side of the capsule:Although the label identifies the medication as furosemide 20 mg, it is not presented in capsule form or printed in this manner. The identifying mark is "EP 116," as described.
D. As a small vial: Furosemide is available in vial form for intravenous or intramuscular use; however, the label and the route specified (PO) indicate this is an oral tablet, not an injectable form.
Correct Answer is ["1.8"]
Explanation
Convert the client's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
154 lb = 154 lb / 2.205 lb/kg = 70 kg (rounded to the nearest whole number).
Determine the total dosage:
The client is prescribed 1 mg/kg of gentamicin.
The client weighs 70 kg.
The total dosage is 1 mg/kg x 70 kg = 70 mg.
Determine the volume per dose:
The gentamicin solution contains 40 mg per 1 mL.
The nurse needs to administer 70 mg per dose.
To find the volume per dose:
40 mg / 1 mL = 70 mg / x mL
Cross-multiplying gives us:
40x = 70
Dividing both sides by 40, we get:
x = 1.75 mL
Round the answer to the nearest tenth:
Rounding 1.75 to the nearest tenth gives us 1.8 mL.
