Question
Chapter 44.4, Problem 2R
Summary Introduction
To review:
The flow of information in a knee-jerk reflex circuit with the help of a diagram.
Introduction:
In a situation where conscious processing of information is not required, a reflex reaction takes place. The reflex reaction is unconscious and involuntary. For example, immediate removal of hand when placed accidentally on fire. To perform the normal movement of legs, the knee-jerk response is required. In this response, the muscles act in opposite manner, i.e., while one pair of muscle is relaxed (the extensor muscle), the other one is in the contracted state (the flexor muscle).

Goal 1: To alleviate the client's overall level, frequency, and intensity of anxiety and PTSD symptoms so that daily functioning remains unimpaired. Objective 1: The client will learn and regularly use at least two anxieties management techniques to reduce anxiety symptoms to less than three episodes per week. Intervention 1: The therapist will provide psychoeducation about anxiety and PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.arrow_forward
