What is the IV:PO ratio for Metoprolol?

1:1
1:2.5
1:3
1:4

The correct answer is: 1:2.5

The IV:PO (intravenous to oral) ratio for Metoprolol is 1:2.5. This means that the dose of Metoprolol administered intravenously is 2.5 times the dose administered orally. This ratio is important for pharmacists and healthcare professionals to ensure proper dosage conversion when transitioning a patient from IV to PO administration of the medication. For the other options: - A. 1:1 is incorrect as the IV:PO ratio for Metoprolol is not equivalent. - C. 1:3 is incorrect as the IV:PO ratio for Metoprolol is 1:2.5, not 1:3. - D. 1:4 is incorrect as the IV:PO ratio for Metoprolol is 1:2.5, not 1:4.
