When transitioning from intravenous to oral morphine, what would the nurse anticipate regarding the oral dose in comparison to the intravenous dose to achieve equianalgesia?
Correct Answer: B
Rationale: When switching from intravenous to oral morphine, a higher oral dose is required to achieve equianalgesia due to significant metabolism from the first-pass effect. Choosing the same oral dose as the intravenous dose would provide less pain relief. Opting for a dose greater than the intravenous dose is necessary to achieve the same analgesic effect. Therefore, options A, C, and D are incorrect.
