A registered nurse (RN) is supervising a licensed practical nurse (LPN) providing care to a client with end-stage heart failure. The client is withdrawn, is reluctant to talk, and shows little interest in participating in hygienic care or activities. Which statement by the LPN to the client indicates that the LPN needs further teaching in the use of therapeutic communication skills?
- A. You are very quiet today.
- B. What are your feelings right now?
- C. Why don't you feel like getting up?
- D. Tell me more about your difficulty with sleeping at night.
Correct Answer: C
Rationale: When a 'why' question is made to the client, an explanation for feelings and behaviors is requested, and the client may not know the reason. Requesting an explanation is a nontherapeutic communication technique. In option 1, the LPN is using the therapeutic communication technique of acknowledging the client's behavior. In option 2, the LPN is encouraging identification of emotions or feelings. In option 4, the LPN is using the therapeutic communication technique of exploring, which is asking the client to describe something in more detail or to discuss it more fully.
