What interventions does the nurse use to promote therapeutic communication with the client diagnosed with obsessive-compulsive disorder (OCD)?

Choice A reason: While the assessment for the potential use of physical restraints may be relevant in specific clinical contexts where a client with bipolar disorder poses an imminent risk of harm to self or others during a severe manic episode, it is not the overarching priority intervention. Restraint use is governed by strict legal, ethical, and clinical guidelines and is considered a last resort after de-escalation, environmental modifications, and pharmacological interventions have been attempted or evaluated. The primary nursing priority must first be the broad concept of ensuring safety, within which restraint assessment may fall as a subcomponent.

Choice B reason: Administering medications as ordered, including mood stabilizers such as lithium carbonate or valproate and atypical antipsychotics such as quetiapine or olanzapine, is an essential component of managing bipolar disorder and reducing the duration and severity of mood episodes. However, medication administration is a dependent nursing function that presupposes physician orders and addresses a specific aspect of treatment. According to Maslow's hierarchy of needs and the nursing priority framework, safety supersedes all other interventions. Medication administration supports safety but is secondary to the priority of ensuring it.

Choice C reason: Maintaining hydration is particularly important in bipolar disorder management, especially for clients receiving lithium carbonate therapy, as sodium and fluid balance directly affect lithium serum levels and risk of toxicity. Dehydration can increase lithium concentrations to toxic levels, causing symptoms ranging from tremor and polyuria to seizures and cardiac dysrhythmia. Despite this importance, hydration maintenance is a physiological supportive measure that is subordinate to the overarching priority of client safety, which encompasses protection from physical harm, self-harm, and harm to others.

Choice D reason: Ensuring client safety is the highest priority nursing intervention for any client with bipolar disorder, particularly during acute manic or depressive episodes. During mania, clients may exhibit impulsivity, reckless behavior, aggression, decreased judgment, hypersexuality, and financial irresponsibility, all of which predispose them to physical harm. During depressive phases, suicidal ideation and self-injurious behaviors pose significant risk. Safety as a priority is consistent with the nursing framework that places life-threatening concerns first, and it serves as the foundational premise upon which all other interventions — medication, hydration, and activity management — are built.

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.
