Final answer:
The decision on what treatment plan to pursue for Jasmine's grandmother would typically be made by the patient herself if capable, or by a designated health care proxy, a living will, or the closest family member if the patient is incapacitated. Doctors and nurses provide medical input but do not have the legal authority to make those decisions without consent.
Step-by-step explanation:
In the scenario presented, the individual who will legally decide what treatment plan to pursue for Jasmine's grandmother is not explicitly mentioned, leading to several possibilities. Generally, if Jasmine's grandmother has the capacity to make her own medical decisions, she would decide for herself. If she lacks capacity and has designated a health care proxy or has a living will, that document would guide who makes decisions and what treatments she would receive. If there is no such documentation, the responsibility typically falls to the closest family members, which could be Jasmine's mom or Jasmine's uncle, depending on family dynamics and legal precedence in the relevant jurisdiction. It's important to note that the doctor and nurse provide medical advice and execute the treatment plan but do not have the legal authority to make decisions on behalf of the patient without proper consent from the patient or their designated decision-maker.
