I am a hospice nurse and I would have educated the new nurse on the reasons for administering the morphine. Unless you are familiar with hospice care it can be scary to give what you think is a lot of morphine. It is to maintain comfort and ease dyspnea in a dying pt. The patient not being responsive isn’t the point in this case, especially with a decubitus that you know is painful. It is also for the family to see that their loved one is at peace and comfortable. Nurses are natural healers, hospice nursing takes a purposeful change in mindset.
