Of the Ethical Theories Described by Chism, Which One or Two

Of the ethical theories described by Chism, which one or two do you think would be most effective in analyzing the following case scenario, and why/how. Responses should be one to two paragraphs in length.
Case scenario: A patient with terminal cancer and believed to have only about 6 months to live has been ordered morphine to help with the pain and, because she is bedridden, is supposed to be turned every two hours to prevent bed sores. However, the patient screams every time she is turned, yelling that the pain is unbearable. Dr. Z, who supervises the nurses, calls a conference to determine what to do. The nurses caring for the patient have differing views: one believes that it is doing more harm than good to turn the patient. Another believes that it is very important to follow the medical literature that advises turning bedridden patients every two hours. A new nursing graduate believes that the patient should be consulted, while another nurse believes that the primary physician on the case should make the final decision.
Tips: Apply the ethical theory you would use in the scenario and how you (or the team) would use it to come to a decision. Be sure to support for your claims.
