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.

Correct Answer is C
Explanation
When faced with an unfamiliar treatment instruction, it is important for the nurse to consult the facility’s policies and procedures to determine the appropriate course of action. These policies and procedures provide guidance on how to carry out treatments safely and effectively and can help ensure that the patient receives the best possible care.
While it may also be appropriate for the nurse to call the physician for clarification (a), check the state’s nurse practice act (b), or contact the nursing supervisor for approval (d), consulting the facility’s policies and procedures should be the first step in determining the appropriate course of action.
