A client whose mania is related to a medical condition asks why the health care provider has prescribed carbamazepine instead of lithium. Which is the nurse's best response?

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.

Choice A reason: Asking whether a client has ever experienced a blackout (alcohol-induced memory impairment) is a clinically relevant question in the assessment of alcohol use disorder, as blackouts are associated with rapid increases in blood alcohol concentration and are indicative of heavy, episodic drinking patterns. However, this question addresses the severity and pattern of drinking behavior rather than the duration or length of time the client has been using alcohol. It does not directly elicit information about when alcohol use was initiated and therefore does not fulfill the specific intent of the nurse's inquiry regarding the timeline of use.

Choice B reason: Asking the client at what age they started using alcohol is the most direct and clinically appropriate question for determining the length of time the client has been consuming alcohol. By establishing the age of onset and comparing it to the client's current age, the nurse can calculate the duration of alcohol use, which has significant implications for assessing the degree of physiological dependence, tolerance, neurobiological impact, and readiness for intervention. Earlier age of onset is associated with higher rates of alcohol use disorder, greater severity of dependence, and poorer treatment outcomes, making this question foundational in a comprehensive substance use assessment.

Choice C reason: Inquiring about legal problems related to alcohol use, such as driving under the influence (DUI), public intoxication, or alcohol-related assault, provides important information about the psychosocial and behavioral consequences of drinking. Legal consequences are 1 of the diagnostic criteria for alcohol use disorder according to the DSM-5. However, this question assesses the social impact of drinking rather than the chronological duration of use. It does not help the nurse establish a timeline of alcohol use and does not answer the question of how long the adolescent has been consuming alcohol.

Choice D reason: Asking whether the client drinks at certain times, such as only in the evenings, only on weekends, or in response to specific triggers, addresses the pattern and context of alcohol consumption, providing insight into habitual use, situational triggers, and potential psychological dependence. This information contributes to a comprehensive substance use assessment but is not directed at determining the length of time alcohol use has been occurring. The question is exploratory regarding drinking habits rather than duration and does not fulfill the nurse's stated assessment goal.
