Which of the following should never be performed by a healthcare professional?

Euthanasia involves intentionally ending a patient's life to relieve suffering, which is ethically and legally prohibited in most healthcare settings. Healthcare professionals are bound by codes of ethics to prioritize patient well-being, comfort, and dignity, making euthanasia incompatible with their professional responsibilities. Performing euthanasia can have serious legal and ethical consequences for healthcare providers, including loss of licensure and potential criminal charges. Therefore, healthcare professionals should not engage in euthanasia practices.
