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 D
Explanation
This response is empathetic and allows the client to express her feelings openly. It demonstrates active listening and validates the client's emotions.
Option A ("I know exactly how you feel") can come across as dismissive or assuming, and it may not accurately reflect the client's unique experience.
Option B ("Most people experience depressed feelings after a divorce") may also come across as dismissive and minimizes the client's feelings.
Option C ("Look on the bright side, you will be glad you divorced him in a couple of years") is not empathetic and does not acknowledge the client's current emotional state.
Correct Answer is ["4"]
Explanation
The prescribed daily dosage is 150 mg.
The tablets available are 37.5 mg each.
To find out how many tablets to administer, we divide the prescribed dosage by the tablet strength.
In this case, 150 mg ÷ 37.5 mg/tablet = 4 tablets.
Therefore, the nurse should administer 4 tablets to meet the prescribed dosage of 150 mg.
