Final answer:
A CTRS should use a probing verbal response.
Step-by-step explanation:
The verbal response that a CTRS (Certified Therapeutic Recreation Specialist) should use when a client repeatedly complains of loneliness, boredom, and being ignored by friends and family is probing.
Probing involves asking open-ended questions to further explore the client's feelings and experiences. It allows the CTRS to gain a deeper understanding of the client's situation and helps the client to express their emotions.
For example, the CTRS could ask the client, 'Can you tell me more about what makes you feel lonely or ignored?'
