A nurse is preparing to administer diphenhydramine 25 mg PO every 6 hours to an older adult patient who has rhinitis.
The available medication is diphenhydramine syrup 12.5 mg/5 mL. How many mL should the nurse administer?
5 mL.
10 mL.
15 mL.
20 mL.
The Correct Answer is B
Choice A rationale
Administering 5 mL of the available medication would only provide 12.5 mg of diphenhydramine, which is half the required dose. Therefore, this is not the correct choice.
Choice B rationale
The available medication is diphenhydramine syrup 12.5 mg/5 mL. To administer the required dose of 25 mg, the nurse would need to give 10 mL of the syrup. This is because 25 mg (required dose) divided by 12.5 mg (dose per 5 mL) equals 2. Therefore, 2 times 5 mL equals 10 mL. This is the correct choice as it provides the exact required dose.
Choice C rationale
Administering 15 mL of the available medication would provide 37.5 mg of diphenhydramine, which is more than the required dose. Therefore, this is not the correct choice.
Choice D rationale
Administering 20 mL of the available medication would provide 50 mg of diphenhydramine, which is double the required dose. Therefore, this is not the correct choice.
