Students' imprudent use of social media might threaten their employability and undermine their emerging professional identities. Most professions acknowledge that any benefits of social media must be balanced against its potential to negatively affect workers' professional lives and the public trust. Professional bodies have developed social media guidelines as a part of more general professional codes of conduct to try to mitigate the legal, ethical, and social risks that imprudent social media use can pose to patients, clients, colleagues, and social media users themselves. This discussion considers examples of students' social media use from health care and other tertiary programs in Australia and Sweden and concludes that universities must confront social media challenges as part of students' educational experience for the development of a responsible and professional digital citizenry.
