A nurse is conducting group therapy with clients who have breast cancer. The nurse should recognize which of the following statements by a client as an example of altruism?

A is incorrect because it is an example of self-disclosure, not altruism. Self-disclosure is sharing personal information or feelings with others. B is incorrect because it is an example of jealousy, not altruism. Jealousy is feeling threatened or resentful by someone else's success or happiness. C is correct because it is an example of altruism, which is helping others without expecting anything in return. Altruism can enhance self-esteem and coping skills for clients who have breast cancer. D is incorrect because it is an example of trust, not altruism. Trust is believing that someone is reliable and honest.
