A nurse is caring for a client who is being treated in the emergency department for a panic attack. Which nursing intervention would be most appropriate?

Choice A reason: Leaving a client who is actively experiencing a panic attack to report symptoms to the psychiatrist on duty is clinically inappropriate and potentially dangerous. A client in the midst of a panic attack experiences overwhelming terror, hyperventilation, palpitations, derealization, and an acute sense of impending doom. Abandonment during this acute state escalates anxiety, undermines the therapeutic relationship, and removes the calming presence of a healthcare provider. The nurse should remain with the client and communicate with other team members through alternate means while maintaining physical and emotional presence at the bedside. Choice B reason: Remaining with the client during an acute panic attack and consistently emphasizing safety and the nurse's continued presence is the most therapeutically appropriate nursing intervention. During a panic attack, the parasympathetic nervous system is overwhelmed by sympathetic activation, triggering the fight-or-flight response mediated by the amygdala and hypothalamic-pituitary-adrenal (HPA) axis. The reassuring physical presence of a calm nurse provides an external source of regulation, reduces autonomic arousal, and prevents catastrophic misinterpretation of somatic symptoms. Therapeutic presence combined with calm, clear communication is a cornerstone of emergency psychiatric nursing care for panic disorder. Choice C reason: Attempting to mimic the client's state of anxiety in an effort to demonstrate empathy is a fundamentally misguided and non-therapeutic nursing behavior. While empathy is a valued component of therapeutic communication, it involves understanding and reflecting the client's emotional experience, not replicating their physiological state of distress. Mimicking anxiety would likely escalate the client's sympathetic arousal through emotional contagion, increase environmental distress, and undermine the nurse's role as a stabilizing therapeutic presence. Nurses should model calm behavior to facilitate de-escalation of the panic response. Choice D reason: Informing a client during an acute panic attack that they are experiencing an acute exacerbation with positive prognosis and low morbidity may contain factual elements regarding the clinical course of panic disorder, but it is not the most appropriate immediate nursing intervention. During a panic attack, cognitive processing capacity is significantly impaired due to the acute stress response. Complex prognostic information delivered at this moment is unlikely to be absorbed and may appear dismissive of the client's immediate experience of terror. Reassurance about safety and the nurse's presence is a more immediately actionable and effective de-escalating strategy.
