Board Rule 217.11 states that in a nurse-patient relationship, the most vulnerable patients are those who are under anesthesia or sedation. This rule provides guidance to help nurses practice safely. Trust is crucial in developing a therapeutic nurse-client relationship, and nurses should listen carefully, treat patients respectfully, respect their privacy, be honest and consistent, follow through on commitments, and have an accepting attitude. Unprofessional conduct can lead to action against a nurse's license. It is important to understand that vulnerable patients include the elderly, children, the mentally ill, sedated and anesthetized patients, those with compromised mental or cognitive abilities, and physically disabled or immobilized patients.
