To have some kind of context, torsemide is also known as the 'water pill' It induces you to produce more urine than usual. Since the doctor prescribed a daily dosage of 20 mg torsemide, this will be the basis of the nurse. If this medication is to be maintained within four days, then the total amount of dosage would be:
20 mg/day * 4 days = 80 mg
The total dosage in 4 days would be 80 mg. But since only 10 mg tablets are available, you have to divide 80 by 10. This means that you need 8 of these 10-mg tablets within the course of four days.
