A nurse is caring for a client who is experiencing manifestations of anxiety. The nurse should recognize which of the following statements about the neurophysiologic manifestations of anxiety as correct?
Correct answer
C
Rationale
The correct answer is C because the amygdala-centered (ACC) circuit of the brain is indeed associated with feelings of panic, which is a common manifestation of anxiety. The amygdala is a key structure in the brain responsible for processing emotions, particularly fear and anxiety. When a person experiences panic, the amygdala becomes highly activated, leading to intense feelings of fear and distress. In contrast, the cortico-striato-thalamo-cortical (CSTC) circuit is more closely linked to motor functions and cognitive processes rather than emotional responses. Choices A, B, and D are incorrect because they incorrectly associate the CSTC circuit with phobias, fear, and apprehension respectively, which are not directly related to this brain circuit in the context of anxiety.
