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 ["2.5"]
Explanation
To calculate the volume of furosemide to be administered, we can use the following formula:
Volume to administer = (Prescribed dose) / (Concentration)
Plugging in the given values:
Volume to administer = 25 mg / (40 mg/4 mL)
Volume to administer = 25 mg x (4 mL / 40 mg)
Volume to administer = 2.5 mL
Therefore, the nurse should administer 2.5 mL of furosemide (Lasix).
Correct Answer is ["7"]
Explanation
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 3.5 mg = 1 tablet / 0.5 mg
Cross-multiplying:
0.5x = 3.5
Solving for x:
x = 3.5 / 0.5
x = 7
Therefore, the nurse should administer 7 tablets of benztropine for each dose.
