Final answer:
A therapeutic response by the nurse is to approach the client calmly and ask about their concerns.
Step-by-step explanation:
A therapeutic response by the nurse when caring for a client who is screaming at staff members and other clients is to approach the client calmly and ask about their concerns (A). This response acknowledges the client's distress and provides an opportunity for them to express their needs or frustrations. Speaking loudly to assert authority and control (B) can escalate the situation and may further agitate the client. Ignoring the client's behavior until they calm down (C) may be ineffective and can make the client feel unheard or invalidated. Confronting the client about their disruptive actions (D) without first addressing their concerns may not be productive.
