Question 1 of 5
A nurse is preparing to administer chlorpromazine hydrochloride 25 mg PO to an older adult client. Available is chlorpromazine hydrochloride syrup 10 mg/5 mL. How many mL should the nurse administer?
Correct Answer: A
Rationale: The correct answer is A: 12.5 mL.
To calculate this, we first determine the total amount needed, which is 25 mg.
Then, we use the concentration of the syrup, which is 10 mg/5 mL. By setting up a proportion (25 mg = x mL), we can cross multiply to find x, which equals 12.5 mL.
Choice B (10 mL) is incorrect because it does not provide the full 25 mg dose.
Choices C (15 mL) and D (5 mL) are incorrect as they do not align with the calculated dose based on the concentration of the syrup.
