What is the Furosemide IV:PO ratio?

  1. 1:1

  2. 1:2

  3. 1:2.5

  4. 2:1

The correct answer is: 1:2

The correct answer is B, 1:2. This means that the dose conversion ratio from intravenous (IV) administration to oral (PO) administration for furosemide is 1:2. In other words, for every 1 mg of furosemide given intravenously, an equivalent dose of 2 mg should be administered orally. This ratio is important for pharmacists to ensure that the patient is receiving the appropriate dose when switching between IV and oral formulations of furosemide. The other options (A, C, and D) are incorrect ratios for furosemide IV:PO conversion and do not reflect the appropriate dosing adjustment needed when transitioning between the two routes of administration.
