Full 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.

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.
Full Explanation
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.
Thorazine 75 mg IM STAT ordered. Thorazine vial reads: 25 mg/mL. How many mLs will the nurse draw up?
Enter the answer as a number only.
Full Explanation
The nurse needs to administer Thorazine 75 mg IM STAT, and the concentration of the medication is 25 mg/mL. To determine the amount of medication to draw up, the nurse can use the following formula:
Dose (in mg) / Concentration (in mg/mL) = Volume (in mL) Plugging in the values, we get:
75 mg / 25 mg/mL = Volume (in mL) Solving for Volume:
Volume = 75 mg / 25 mg/mL = 3 mL
Therefore, the nurse should draw up 3 mL of Thorazine from the vial.
