Final answer:
When a nurse aids accident victims, they uphold the principle of beneficence, which is about acting to benefit others. Other ethical principles such as nonmaleficence and autonomy may also be involved, ensuring no additional harm and respecting patient choices.
Step-by-step explanation:
When a registered nurse provides medical assistance to victims of an accident, the ethical principle primarily upheld is the principle of beneficence. This principle directs healthcare professionals to act in ways that benefit others and contribute to their well-being. Providing needed medical aid after an accident is a clear example of acting for the good of others. Moreover, the ethical principles of nonmaleficence and autonomy may also come into play, ensuring that no further harm is caused and that the victim's choices are respected if they are able to communicate their wishes.
These principles are foundational in health care ethics, guiding the actions and decisions of healthcare professionals as they interact with patients. Particularly in emergencies, such as accidents, nurses and physicians are often guided by these ethical considerations to ensure that their patients receive the highest standard of care while maintaining a commitment to ethics and humanity.
