A client is prescribed cimetidine 400 mg PO twice daily. It is available as an oral liquid of 100 mg per teaspoon. How many teaspoons should the client take per dose?
4 teaspoons
2 teaspoons
1 teaspoon
3 teaspoons
The Correct Answer is B
A. 4 teaspoons – This is incorrect because 4 teaspoons would provide 400 mg (100 mg x 4 = 400 mg), but the correct dose per administration is 400 mg. However, this is not the correct calculation, as only 2 teaspoons are needed.
B. 2 teaspoons – This is correct. The prescribed dose is 400 mg, and since the medication concentration is 100 mg per teaspoon, 2 teaspoons (100 mg x 2 = 200 mg) is the correct dose for each administration.
C. 1 teaspoon – This is incorrect because 1 teaspoon would only provide 100 mg, and the prescribed dose is 400 mg. This is not enough to meet the prescribed dose.
D. 3 teaspoons – This is incorrect because 3 teaspoons would provide 300 mg (100 mg x 3 = 300 mg), which is not enough to meet the prescribed 400 mg dose.
