After a biopsy,the client tells his physician that if the mass is malignant,he wants to know,but he does not want any further treatment or his family to know.What would be a major nursing responsibility in caring for the client?

A) Convince him to tell his family
B) Suggest he consider treatment options
C) Support his decisions regarding care
D) Contact his family so they can help him

The major nursing responsibility in this scenario is to support the client's decisions regarding his care, which includes respecting his wishes to not have any further treatment and to keep the information from his family. The nurse should provide emotional support and help the client cope with the potential diagnosis, while also ensuring that he is fully informed about his options and the implications of his decision. It is not appropriate to try to convince the client to tell his family or to contact them without his consent.
