Ethics is a set of values and moral principles that shape individual or group conduct. Bioethics is an applied ethics discipline analyzing social, legal, and philosophical issues arising from connections between life sciences, medicine, and healthcare. While ethics provides the broader framework for moral decision-making, bioethics specifically applies ethical principles to healthcare and medical contexts.

Deontology emphasizes obligations and the morality of actions regardless of consequences, evaluating situations based on justice and truth. Utilitarianism relies on outcomes, determining right or wrong actions by their effects and prioritizing the greatest benefit for the most people. In healthcare, a deontologist keeps promises like confidentiality even if harmful, while a utilitarian allocates limited medication to the patient with the highest survival chance.

Natural rights are inherent to humanity and exist independent of society. Conventional rights are created by humans and reflect societal values. Both types are ethically correct and justifiable because large populations advocate for them. In healthcare, protecting patient confidentiality represents a conventional right widely recognized and protected by society.

Virtue ethics evaluates individuals by character rather than isolated actions, considering morals, reputation, and motivation. It emphasizes that good character leads to consistent ethical behavior. In healthcare, a virtuous physician exhibits compassion, empathy, and honesty when disclosing a terminal diagnosis, reflecting integrity and moral character rather than focusing solely on the decision's outcome.

Ethical theories represent viewpoints from which people seek moral direction and deliver clear understanding of moral necessities and responsibilities. Different theories explain what people might do depending on the situation and ethical dilemma faced. They provide systematic frameworks—whether emphasizing duties, consequences, rights, or character—to guide healthcare professionals through complex moral situations.

In virtue ethics, character determines ethical conduct and shapes consistent behavior. A nurse's morals, reputation, and motivation are central to evaluating their actions. Rather than judging isolated decisions, virtue ethics focuses on whether the nurse demonstrates integrity, compassion, and honesty. This character-based approach emphasizes that ethical nursing flows from the nurse's moral foundation and values.

Rights theory asserts that widely recognized and accepted rights must be safeguarded, even if specific actions might yield better overall consequences. In healthcare, protecting patient confidentiality is ethically justifiable due to widespread societal advocacy. When a healthcare professional discloses sensitive information without consent, it violates the patient's right to privacy, which rights theory prioritizes as fundamental.
