Which field explores moral questions arising from medical practice and research?

The correct answer is bioethics, as it is the field specifically dedicated to examining the moral implications and ethical issues that arise in the context of biology and medicine. Bioethics encompasses a broad range of topics, including medical practice, research, patient rights, and the responsibilities of healthcare professionals. It seeks to address complex questions related to life sciences, healthcare delivery, and the ethical treatment of patients and research subjects.

While medical ethics, clinical ethics, and healthcare ethics all focus on various aspects of ethical dilemmas in healthcare settings, bioethics has a wider scope. It not only addresses practitioner-patient interactions but also considers societal implications and the ethical challenges posed by advancements in medical technology and genetic research. This makes bioethics the most comprehensive choice for exploring moral questions related to both medical practice and research.
