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.

Correct Answer is ["1.5"]
Explanation
Understanding the Problem:
We need to administer 15 mg of furosemide.
The available ampoule contains 10 mg/mL of furosemide.
Solution:
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (15 mg) and the concentration of the medication (10 mg/mL).
Proportion:
x mL / 15 mg = 1 mL / 10 mg
Cross-multiply:
10x = 15
Solve for x:
x = 15 / 10
x = 1.5
Therefore, the nurse should administer 1.5 mL of furosemide.
Correct Answer is ["37.3"]
Explanation
To convert Fahrenheit to Celsius, you can use the following formula:
Celsius = (Fahrenheit - 32) x 5/9
In this case, the Fahrenheit temperature is 99.2. Plugging it into the formula:
Celsius = (99.2 - 32) x 5/9
Celsius = 67.2 x 5/9
Celsius = 37.33
Rounding to the nearest tenth, the Celsius temperature is 37.3.
