Which ethical principle would be violated if a nurse administered medication without consent?

The ethical principle that would be violated if a nurse administered medication without consent is autonomy. Autonomy refers to the right of individuals to make decisions about their own healthcare. This principle emphasizes the importance of informed consent, recognizing that patients have the right to be involved in their own medical decisions. By administering medication without obtaining consent, the nurse disregards the patient's right to self-determination and choice regarding their treatment. Respecting autonomy is fundamental in nursing practice, as it establishes a trusting relationship between healthcare providers and patients and acknowledges the individual's personal values and preferences.
