Order reads Zyprexa 15 mg PO at HS for psychosis. The nurse has Zyprexa 7.5 mg tablets in med drawer. How many tablets will the nurse administer?
Enter answer as a number only.
The Correct Answer is ["2"]
The nurse will administer 2 tablets of Zyprexa 7.5 mg to equal the ordered dose of Zyprexa 15 mg. Explanation:
"PO" stands for "by mouth" and "HS" stands for "at bedtime". The medication order is for Zyprexa 15 mg to be taken orally at bedtime for the treatment of psychosis. The nurse has Zyprexa 7.5 mg tablets available.
To determine how many tablets the nurse should administer, we need to do a dose calculation. We know that the ordered dose is 15 mg and the available dose is 7.5 mg. Therefore, we can set up a proportion:
7.5 mg / 1 tablet = 15 mg / x tablets Solving for x, we can cross-multiply:
7.5 mg * x tablets = 15 mg * 1 tablets x = 15 mg / 7.5 mg
x = 2 tablets
Therefore, the nurse should administer 2 tablets of Zyprexa 7.5 mg to equal the ordered dose of Zyprexa 15 mg.

Therefore, the nurse should administer 4 tablets to meet the prescribed dosage of 150 mg.
