Final answer:
The nurse's action is a violation of patient privacy and professional boundaries.
Step-by-step explanation:
The action taken by the nurse, who takes a picture of one of his coworkers walking a patient, can be best described as a violation of patient privacy and professional boundaries.
By capturing and sharing an image of a patient without their consent, the nurse breaches their right to privacy and confidentiality. This type of behavior is not only unprofessional but also goes against the ethical principles of healthcare.
It is important for healthcare professionals to prioritize patient privacy and maintain professional boundaries in order to ensure trust and maintain the therapeutic relationship with their patients.
