A nurse is preparing to administer prednisone 40 mg PO to an adolescent client. Available is prednisone oral solution 5 mg/5 mL. How many ml. should the nurse administer?
Correct answer
B
Rationale
The correct answer is B. To calculate the amount of prednisone oral solution to administer, we can use the formula: Desired dose/Stock dose x Volume of stock solution. In this case, Desired dose is 40 mg, Stock dose is 5 mg/5 mL, and Volume of stock solution is unknown (x mL). Therefore, 40 mg/5 mg x 5 mL = 40 mL. This calculation ensures the correct dosage is administered. Choice A is incorrect because administering 40 mL would result in a much higher dose than prescribed. Choices C-G are irrelevant since the correct answer has been determined.
