The health-care provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How many tablets should the nurse plan to administer?
1 tablet.
1/2 tablet.
2 tablets.
1 1/2 tablets.
The Correct Answer is C
To determine the number of tablets needed, we can set up a proportion:
x tablets / 7.5 mg = 1 tablet / 5 mg
Cross-multiplying:
5x = 7.5
Solving for x:
x = 7.5 / 5
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of metolazone.

Explanation
To calculate the volume of diazepam to be administered, we can use the following formula:
Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)
Plugging in the given values:
Volume (mL) = 12.5 mg / 5 mg/mL
Calculating the result:
Volume (mL) = 2.5 mL
