What would be the most appropriate action by the student nurse when the client asked the student nurse to keep it a secret that the client plan to kill a family member?

A. Restricted affect: Restricted affect indicates a limited range of emotions but not a complete lack of expression.
B. Broad affect: Broad affect indicates a wide range of emotional expressions, which is not the case here.
C. Blunt affect: Blunt affect indicates a severe reduction in the intensity of emotional expression, but some expression is still present.

A. "It enables clients to see that other individuals have mental health issues." This option is partially correct because one of the benefits of group therapy is that it helps clients understand they are not alone in their struggles and that others share similar issues. This can be comforting and validating for clients.
B. "It provides a forum to reinforce client teaching regarding medication administration." This is not typically the primary function of group therapy. While medication education may occasionally be part of group discussions, the main focus of group therapy is on interpersonal interactions and support rather than specific teaching about medication.
C. "It is economical, since one staff member can treat many clients at once." Although group therapy can be cost-effective, this reason is secondary to its therapeutic value. The primary goal of group therapy is to provide therapeutic benefits through interaction and shared experiences rather than focusing on cost-efficiency.
D. "It establishes a situation where the client can relate to others and share perceptions." This option is the most accurate. Group therapy allows clients to relate to others with similar issues, share experiences, and gain support, which is fundamental to the therapeutic process.
