NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

According to the text, what is the IV/IM to PO conversion ratio for Morphine?

1. 10 mg IV/IM : PO 20 mg

2. 5 mg IV/IM : PO 15 mg

3. 10 mg IV/IM : PO 30 mg

4. 1 mg IV/IM : PO 3 mg

The correct answer is: 10 mg IV/IM : PO 30 mg

Morphine is commonly administered intravenously (IV) or intramuscularly (IM) in hospital settings and orally (PO) for outpatient use. The IV/IM to PO conversion ratio for Morphine helps healthcare providers calculate equivalent doses when switching between these routes of administration. In this case, the correct conversion ratio for Morphine is 10 mg IV/IM to 30 mg PO, which is option C. This means that 10 mg of Morphine administered intravenously or intramuscularly is equivalent to 30 mg of Morphine taken orally. It is important to understand these conversion ratios to ensure patients receive the appropriate dose of medication regardless of the route of administration. Incorrect options include ratios that do not match the standard conversion ratio for Morphine.
