What is the IV:PO ratio for loop diuretics, except for Furosemide?

1:1
1:2
1:2.5
2:1

The correct answer is: 1:1

Option B, C, and D are incorrect because they do not reflect the standard IVPO ratio for loop diuretics, which is 1:1. These options all have a higher ratio, meaning that the oral dosage is higher than the intravenous dosage. However, Furosemide has a unique IV:PO ratio of 1:2. This means that the oral dosage is double the intravenous dosage, which is why it is the exception to the standard ratio of 1:1 for other loop diuretics.
