Do nurses ever have the right in breaking patients confidentiality?

Yes! If it is necessary to prevent harm to the patient or to prevent the patient from harming themselves or someone else such as when a patient threatens to kill themselves or someone else. This situation usually occurs when dealing with patients with psychological problems. However if information about a patient is used for any purpose other than health care, the health care worker is most likely in violation of HIPAA. HIPAA is the Health Insurance Portability and Accountability Act. It protects the rights of patients.
