The nurse is assigned to care for a client diagnosed with psoriasis. Which behavior by the nurse addresses this client's psychosocial need for acceptance?

A. Wearing gloves when interviewing the client. This behavior may make the client feel stigmatized or rejected, as it could imply that the nurse perceives them as contagious or untouchable. B. Allowing the client to ventilate feelings. While this is important for emotional support, it does not directly address the psychosocial need for acceptance. C. Encouraging the client to join a support group. This can help the client feel less isolated and gain support from others with similar experiences, but it is not as immediate or direct as personal interaction. D. Shaking the client's hand during an introduction. This gesture of physical contact can significantly convey acceptance and normalcy, helping the client feel respected and accepted despite their condition.
