A client with a panic disorder is participating in panic control treatment. Which action indicates to the nurse that the client is using techniques to control panic reactions?

Choice A reason: Laying down in bed with eyes closed during a panic response does not represent the active application of a learned panic control technique. While rest and reduced sensory input may be instinctive responses to anxiety, this behavior does not constitute evidence of the client implementing a structured therapeutic strategy for panic management. Panic control treatment (PCT), a specific cognitive-behavioral intervention for panic disorder, teaches clients active techniques such as controlled breathing, interoceptive exposure, and cognitive restructuring. Passive recumbence does not reflect the application of any of these evidence-based techniques and does not indicate therapeutic progress. Choice B reason: Pacing in the room during a panic episode reflects psychomotor agitation, which is a physiological expression of sympathetic nervous system hyperactivation and heightened anxiety rather than the implementation of a panic control strategy. Pacing increases physical activity and metabolic demand, which can further stimulate the sympathoadrenal axis, elevate heart rate, and worsen hyperventilation, effectively exacerbating rather than managing the panic response. This behavior does not correspond to any component of panic control treatment and does not indicate that the client is applying therapeutic self-regulation techniques. Choice C reason: Sitting in a chair away from others may represent a degree of environmental self-management, such as reducing social stimulation, but it is a passive avoidance behavior rather than an active panic control technique. In fact, avoidance and withdrawal are recognized maintaining factors in panic disorder and are specifically targeted for reduction in panic control treatment through exposure-based techniques. While creating a quiet environment can support relaxation efforts, simply sitting alone without concurrent application of breathing or cognitive techniques does not constitute evidence that the client is using acquired panic control strategies learned during treatment. Choice D reason: Engaging in deep breathing, specifically controlled diaphragmatic breathing, is a core and central component of panic control treatment. During a panic attack, hyperventilation leads to hypocapnia (decreased carbon dioxide levels), which triggers cerebral vasoconstriction, paresthesias, dizziness, and increased somatic symptoms, further amplifying the panic response. Controlled deep breathing corrects the respiratory alkalosis, restores normocapnia, activates the parasympathetic nervous system via vagal stimulation, and reduces heart rate and muscle tension. The intentional use of this technique during an anticipated or actual panic episode directly demonstrates that the client is applying the skills acquired in treatment to self-regulate their physiological and psychological arousal.
