Step-by-step explanation:
An ethical dilemma is a situation in which an apparent operational conflict between two ethical imperatives is presented in such a way that obedience to one of them implies the transgression of the other. In general, it is called an ethical dilemma when an agent (the professional, in this case) has reasons to carry out two actions (or more), each of which favors a different principle, and it is not possible to fulfill them without violating any of they. In this way, the agent is in a situation in which he is condemned to commit a foul: no matter what he does, he will do something "wrong" or will miss an obligation.
