A client that tells the nurse that they are upset because their partner no longer wants to continue the relationship. Which statement made by the client indicates that the end of the relationship is related to the client's narcissistic personality disorder?

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.

Choice A reason: Naltrexone is an opioid receptor antagonist used for the maintenance of sobriety in alcohol use disorder and as a long-term pharmacological adjunct in opioid use disorder following detoxification. It is available in oral formulation (ReVia) and as an extended-release injectable formulation (Vivitrol). Critically, naltrexone is not indicated for the acute reversal of opioid-induced respiratory depression. Its use in active opioid intoxication without full detoxification can precipitate severe opioid withdrawal. Naltrexone is a maintenance, not an emergency reversal, agent and would not be the appropriate medication in this acute overdose scenario.

Choice B reason: Varenicline (Chantix) is a partial agonist at the alpha-4 beta-2 nicotinic acetylcholine receptor, primarily used as a smoking cessation pharmacotherapy. It reduces nicotine cravings and withdrawal symptoms by providing partial receptor stimulation while blocking nicotine binding. Varenicline has no pharmacological activity at opioid receptors and no role in the acute management of opioid toxidrome. Administering this medication in the context of acute heroin-induced respiratory depression would be clinically inappropriate and ineffective, as it does not possess opioid receptor antagonist properties.

Choice C reason: Bupropion is a norepinephrine-dopamine reuptake inhibitor (NDRI) used as an antidepressant and as a pharmacological aid for smoking cessation (marketed as Zyban for this indication). It acts by inhibiting the reuptake of norepinephrine and dopamine in the presynaptic terminal, thereby increasing their synaptic concentration. Bupropion has no opioid receptor activity and is not indicated in the management of acute opioid overdose. Its administration in this emergency setting would provide no clinical benefit and would delay delivery of the appropriate reversal agent.

Choice D reason: Naloxone (Narcan) is a pure opioid receptor antagonist with high affinity for mu, kappa, and delta opioid receptors. It competitively displaces opioids from their receptor sites, rapidly reversing opioid-induced respiratory depression, miosis (pinpoint pupils), and unconsciousness within 2 to 5 minutes when administered intravenously. The clinical triad of unconsciousness, slow respirations, and pinpoint pupils (miosis) described in the question is the classic presentation of acute opioid toxidrome. Naloxone is the emergency pharmacological standard of care for opioid overdose reversal and is endorsed by emergency medicine, toxicology, and nursing guidelines as the immediate life-saving intervention in this scenario.
