In my opinion, it is essential to make the students realize their mistake in this matter, especially given that patient care and responsibility are paramount in the medical field. Engaging in social media trends while on duty is indeed unprofessional behavior; however, a final-year student's future could also be at stake. Therefore, I believe the punishment should be such that it allows them to learn from their error, rather than jeopardizing their entire future. You are absolutely right that one must consider the potential consequences before taking any action online, as a few moments of amusement can sometimes come at a very high cost.
