A nurse is assisting with the care of 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?
The amygdala-centered circuit of the brain is associated with feelings of panic.
The amygdala-centered circuit of the brain is associated with feelings of apprehension.
The cortico-striato-thalamo-cortical circuit of the brain is associated with feelings of fear.
The cortico-striato-thalamo-cortical circuit of the brain is associated with phobias.
The Correct Answer is A
Choice A reason: The amygdala is a primary component of the limbic system, highly involved in processing emotional responses, particularly the fear and panic circuit. Hyperactivity in this neural network is linked to the rapid, physiological, and emotional surge characteristic of panic attacks, which involve intense sympathetic nervous system activation.
Choice B reason: Apprehension is generally associated with broader anxiety states involving cortical engagement rather than the acute, rapid-response fear-panic loop of the amygdala. While the amygdala processes threat, the specific cognitive interpretation of apprehension involves higher-order processing circuits rather than the primary amygdala-centered panic response circuit alone.
Choice C reason: The cortico-striato-thalamo-cortical (CSTC) circuit is primarily involved in repetitive behaviors, cognitive control, and motor functions, often implicated in obsessive-compulsive disorders. Fear is primarily mediated by the limbic-amygdala pathway, and mapping it to the CSTC circuit is neuroanatomically inaccurate regarding the primary pathogenesis of fear.
Choice D reason: Phobias are complex anxiety conditions characterized by specific fear responses. While they involve the amygdala, the CSTC circuit is not the primary driver of phobic responses. Phobias are predominantly defined by amygdala-mediated conditioned fear responses rather than the dysfunction of the striatal-thalamic loops typically associated with obsessive behaviors.

Correct Answer is C
Explanation
Choice A reason: A Penrose drain is an open, passive drainage system that relies on gravity and capillary action, not suction. Connecting it to suction would negate its design, potentially pulling tissue into the drain or causing localized trauma, which is contraindicated for this specific type of device.
Choice B reason: A Penrose drain does not have a collection device like a Jackson-Pratt or Hemovac drain. It is an open system that allows drainage to flow directly onto the dressing. Therefore, it is impossible to empty a device that does not exist, making this action clinically irrelevant.
Choice C reason: A split or perforated gauze is used to provide a clean, absorbent barrier around the exit site of the drain. This protects the periwound skin from the corrosive effects of the exudate and helps maintain a clean environment, reducing the risk of skin maceration and localized infection.
Choice D reason: When cleaning any surgical site, the nurse must work from the cleanest area to the dirtiest area. The correct technique is to clean the drain site first (cleanest) and then move outward in a circular motion toward the surrounding skin (dirtiest), not from outside to inside.
Correct Answer is B
Explanation
Choice A reason: Data gathering regarding the home situation is a primary objective during the orientation and working phases of the nurse-client relationship. This information is necessary for the initial development of the plan of care and should not be left for the termination phase, which is dedicated to summarizing care.
Choice B reason: The termination phase is characterized by reviewing the progress made during the relationship. Summarizing accomplished treatment goals provides the client with a sense of achievement, acknowledges the work done, and prepares them for the transition to self-management or the next level of care after the therapeutic relationship concludes.
Choice C reason: Providing personal contact information is a severe violation of professional boundaries. The nurse-client relationship must remain strictly professional and time-limited. Encouraging the client to contact the nurse personally after the conclusion of the professional relationship is unethical and disrupts the client’s ability to use official support systems.
Choice D reason: Introducing the concept of discharge planning should occur much earlier, typically during the initial orientation and throughout the working phases. Waiting until the termination phase to discuss discharge is inappropriate, as the plan should have been well-established, evaluated, and transitioned into the patient's daily life by this stage.
