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 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.

The State nurse practice act outlines the legal scope of practice for nurses in a particular state, including the tasks and procedures that nurses are authorized to perform. Therefore, if the nurse is unsure whether a particular procedure falls within their scope of practice, the State nurse practice act is the best source of information to consult. The nurse should review the act to determine whether they have the necessary knowledge, skills, and authority to perform the procedure safely and legally.

Regional nurse practice acts and community nurse practice acts may provide additional guidance but are not as authoritative as the State nurse practice act.

While Google may provide some information, it is important for the nurse to rely on reliable and authoritative sources of information to ensure safe and effective patient care.
