Simulated
A 48-year-old client with cancer has been receiving 10 mg of I.V. morphine while hospitalized. In control, the nurse should administer which of the following doses of oral morphine?
Correct answer
B
Rationale
The equianalgesic conversion from 10 mg I.V. morphine to oral morphine (1:3 ratio) is 30 mg, as oral morphine has lower bioavailability due to first-pass metabolism.
