A client is prescribed cimetidine 200 milligrams (mg) PO twice daily. It is available as an oral liquid of 100 mg per teaspoon. How many teaspoons should the nurse instruct the client to take per dose?
Correct answer
C
Rationale
The correct answer is C: 2 teaspoons. To determine this, we can calculate as follows: The client is prescribed 200 mg PO twice daily, so the total daily dose is 400 mg. Since each teaspoon contains 100 mg, the client needs 4 teaspoons per day. Dividing this by 2 doses gives 2 teaspoons per dose. Therefore, the nurse should instruct the client to take 2 teaspoons per dose.
Choice A is incorrect because 1 teaspoon is only 100 mg, which is half the prescribed dose. Choice B is incorrect as it is too high and exceeds the prescribed 200 mg per dose. Choice D is also incorrect as 3 teaspoons would provide 300 mg, which is more than the prescribed dose of 200 mg.
