Final answer:
The ethical decision by the doctor to prescribe Nalfon is analyzed using three ethical theories. Utilitarian ethics question the balance of pain relief versus harm, duty-based ethics looks at the doctor's obligations and possible harm, and virtue-based ethics considers the moral character involved in the decision. Given the patient's severe reaction to the medication, it may not have been the most ethical choice.
Step-by-step explanation:
The ethical considerations of the doctor's decision to prescribe Nalfon, a nonsteroidal anti-inflammatory drug (NSAID), to a 91-year-old patient at the request of the patient's son involve analyzing the consequences and duties involved in such a decision. Utilitarian ethics would assess the overall happiness or utility generated by this decision. It would question whether the pain relief provided by Nalfon outweighs the potential for harm, such as the severe gastric bleed that the patient experienced. Duty-based ethics would consider the doctor's obligations to respect the patient's autonomy and the son's wishes while also doing no harm to the patient. Finally, virtue-based ethics would reflect on the character of the doctor and the moral excellences that should come into play, such as compassion, wisdom, and justice, in making medical decisions.
Given the serious side effects associated with NSAIDs, particularly in the elderly who may have an increased risk for gastrointestinal bleeding, the decision to prescribe Nalfon without adequately considering safer alternatives or the patient's past experiences with such medication may not align with utilitarian principles of maximizing happiness. Duty-based ethics might criticize the doctor for disregarding the potential risks of NSAIDs known in geriatric medicine. From a virtue-based perspective, the doctor's decision may lack the necessary prudence and care required when treating a vulnerable patient.
