For me, maintaining professional competence would be maintenance of my personal health and joy in life. I believe if I feel healthy, am physically active, and have a strong mental support system, I am better equipped to go into the hospital and care for patients. This also involves doing things that I enjoy outside of work and spending time with people I care for. If I am happy in my personal life, I am better-prepared to come into work and care for patients because I myself am taken care of. As stated in the previous topic, if we struggle to care for ourselves, it becomes more difficult to care for patients.
If I saw a colleague conducting unethical behavior, my reaction would depend on how severe it was. If it was something that was perhaps a break in policy or workplace rules but was not necessarily harmful to anyone, I would approach and let them know I witnessed what happened and would appreciate that they do not do it again. I would also let them know that if they ever need help with something to please come to me first before breaking that rule/policy. If their act was harmful to a patient/colleague, I would let the proper resource know because endangerment of others is unacceptable. I would also intervene as soon as possible to try to avoid anyone getting hurt.
