💠 Severe muscle rigidity, especially progressing rapidly over hours, is a hallmark feature of neuroleptic malignant syndrome (NMS).

💠 Hyperthermia (102.8°F), diaphoresis, tachycardia, hypertension, and tachypnea indicate autonomic instability, a defining characteristic of NMS.

💠 Drooling and difficulty swallowing reflect muscle rigidity and altered neuromuscular control, commonly seen in NMS.

💠 Risperidone, although an atypical antipsychotic, can still precipitate NMS through dopamine D2 receptor blockade.

💠 The most urgent action is immediate provider notification so the medication can be stopped and emergency interventions (cooling, IV fluids, ICU care, possible dantrolene or bromocriptine) can be initiated.

Hypertensive crisis

💠 Hypertensive crisis is most commonly associated with MAOI–tyramine interactions, not antipsychotic medications.

💠 Dietary modification is not an emergency intervention and does not address muscle rigidity or hyperthermia.

Tardive dyskinesia

💠 Tardive dyskinesia presents with chronic, involuntary movements such as lip-smacking and tongue protrusion, not acute rigidity and fever.

💠 It develops after long-term exposure, not within hours.

Agranulocytosis

💠 Agranulocytosis presents with infection signs, sore throat, and low WBC count, not autonomic instability or rigidity.

💠 It is most strongly associated with clozapine, not risperidone.

💠 Fluphenazine is a high-potency typical antipsychotic, producing strong dopamine (D2) receptor blockade in the nigrostriatal pathway, which commonly causes extrapyramidal symptoms (EPS).

💠 Shuffling, propulsive gait reflects bradykinesia and rigidity, closely mimicking Parkinson disease.

💠 Masklike facial expression indicates reduced facial muscle movement due to dopamine inhibition.

💠 Drooling (sialorrhea) occurs from impaired voluntary motor control of swallowing and facial muscles.

💠 The expected management is to reduce the antipsychotic dose and add an anticholinergic agent (e.g., benztropine) to rebalance dopamine–acetylcholine activity.

Neuroleptic malignant syndrome (NMS)

💠 NMS presents with high fever, severe rigidity, altered mental status, and autonomic instability, which are not present here.

💠 It is a medical emergency, unlike the localized motor findings seen in this client.

Serotonin syndrome

💠 Serotonin syndrome is associated with serotonergic drugs and causes hyperreflexia, clonus, agitation, and hyperthermia.

💠 Typical antipsychotics do not produce serotonin toxicity as described.

Akathisia

💠 Akathisia is characterized by subjective inner restlessness and inability to sit still, not rigidity or shuffling gait.

💠 Benzodiazepines are not first-line for Parkinson-like EPS.

💠 Airway and oxygenation are foundational physiologic needs, and this client is already in acute respiratory failure with severe hypoxemia.

💠 Combative behavior with attempts to remove the endotracheal tube places the client at immediate risk of airway loss, hypoxia, aspiration, and death.

💠 Propofol (Diprivan) provides rapid, titratable sedation, preventing self-extubation and allowing effective mechanical ventilation.

💠 Sedation promotes ventilator synchrony, reducing oxygen demand and worsening respiratory distress.

💠 According to Maslow, safety and physiologic needs must be protected before all higher-level needs, making this intervention appropriate and lifesaving.

💠 Maslow’s hierarchy prioritizes patient survival, not workflow efficiency.

💠 Sedation is never justified for staff convenience.

Respiration already compromised, sedation won’t do harm

💠 This reasoning minimizes risk and misapplies Maslow’s theory.

💠 Sedation is indicated to prevent imminent harm, not because harm is unavoidable.

Interpersonal relationships and communication

💠 Interpersonal needs are lower priority than airway and safety.

💠 Removing the ET tube would worsen hypoxia, not improve communication.

💠 Lithium is excreted almost entirely by the kidneys, making serum levels highly sensitive to changes in renal function and fluid status.

💠 Furosemide causes sodium and fluid loss, and because lithium follows sodium, the kidneys reabsorb more lithium, increasing serum levels.

💠 Congestive heart failure reduces renal perfusion, further impairing lithium clearance and making levels unpredictable.

💠 Fluid shifts and dehydration commonly occur in CHF management, compounding the risk of lithium accumulation.

💠 This combination makes frequent and careful lithium level monitoring essential to prevent toxicity.

Psoriasis treated with topical triamcinolone

💠 Topical corticosteroids have minimal systemic absorption and do not affect renal lithium clearance.

💠 There is no significant impact on sodium or fluid balance.

Epilepsy treated with diazepam

💠 Diazepam does not alter renal function or sodium handling.

💠 It has no direct interaction with lithium levels.

Arthritis treated with acetaminophen

💠 Acetaminophen is preferred for pain control in patients on lithium.

💠 Unlike NSAIDs, it does not increase lithium serum concentrations.

💠 The oral stage (birth–18 months) centers on gratification through feeding, sucking, and dependency on caregivers.

💠 Fixation at this stage can develop when oral needs are overgratified or undergratified, disrupting normal emotional development.

💠 Adults with oral fixation may become manipulative, using others to meet emotional or physical needs.

💠 Suspiciousness reflects underlying insecurity and fear of abandonment rooted in early dependency conflicts.

💠 Traits such as self-indulgence and poor impulse control align closely with oral-stage fixation.

Anal

💠 The anal stage focuses on control, orderliness, and power struggles, not dependency-based manipulation.

💠 Fixation results in rigidity or stubbornness, rather than exploitative interpersonal behavior.

Phallic

💠 The phallic stage involves identity formation and Oedipal conflicts.

💠 Fixation may lead to vanity or recklessness, not suspicious manipulation.

Genital

💠 The genital stage reflects mature sexuality and balanced relationships.

💠 It is not associated with immature, self-centered behavior

💠 This stage occurs during early childhood (1–3 years), when individuals learn to assert independence while regulating impulses.

💠 Successful resolution leads to self-control and willpower, allowing a person to delay gratification and make healthy choices.

💠 Failure to master this stage results in impulsivity, poor self-regulation, and dependence, reflected in “I want it now” behavior.

💠 Learning limits and consequences during this stage teaches individuals that not all desires can be immediately satisfied.

💠 The statement’s emphasis on fighting impulses and building self-discipline directly aligns with achieving autonomy rather than shame or doubt.

Trust versus Mistrust

💠 This stage focuses on basic trust in caregivers, not impulse control or delayed gratification.

💠 It does not address decision-making or self-discipline.

Initiative versus Guilt

💠 This stage emphasizes goal-setting and imagination, not restraint of impulses.

💠 The core conflict is initiative, not self-control.

Industry versus Inferiority

💠 This stage centers on competence, productivity, and skill mastery, particularly in school-age children.

💠 It does not primarily involve impulse regulation or willpower

💠 Free association is a core psychoanalytic technique used to allow unconscious thoughts and feelings to surface without censorship.

💠 Dream analysis is central to psychoanalysis and is used to explore unconscious desires, fears, and internal conflicts.

💠 Transference is deliberately facilitated, allowing the client to project unconscious feelings onto the therapist for insight and resolution.

💠 Therapy is long-term and intensive, often lasting years with regular sessions, which matches the 3-year weekly treatment described.

💠 The primary goal is insight into unconscious processes, leading to enduring personality restructuring rather than short-term symptom relief.

💠 Behavioral therapy focuses on observable behaviors and conditioning, not unconscious processes.

💠 It does not use dream analysis or transference.

Interpersonal Therapy (IPT)

💠 IPT is time-limited and present-focused, addressing current relationships and roles.

💠 It does not explore unconscious conflicts or early childhood experiences.

Cognitive therapy

💠 Cognitive therapy targets distorted conscious thought patterns, not the unconscious mind.

💠 Techniques such as free association and dream interpretation are not used.

💠 Fluphenazine decanoate is a high-potency typical antipsychotic, and chronic dopamine D2 receptor blockade over years significantly increases the risk of tardive dyskinesia (TD).

💠 Involuntary facial movements, grimacing, and lip-smacking are classic early manifestations of TD.

💠 Slow, twisting, snakelike movements of the neck and shoulders represent choreoathetoid dyskinesias, a hallmark of advanced TD.

💠 TD typically develops after months to years of antipsychotic therapy, distinguishing it from acute extrapyramidal symptoms.

💠 The nurse should recognize TD promptly and anticipate provider-directed pharmacologic intervention, such as the prescribed medication, to manage symptoms and prevent progression.

Agranulocytosis

💠 Agranulocytosis presents with infection, fever, and low white blood cell counts, not abnormal involuntary movements.

💠 It is most strongly associated with clozapine, not fluphenazine.

Anticholinergic effects

💠 Anticholinergic effects include dry mouth, blurred vision, urinary retention, and constipation.

💠 They do not cause choreiform or writhing movements.

Tourette’s syndrome

💠 Tourette’s syndrome is a childhood-onset neurodevelopmental disorder characterized by motor and vocal tics.

💠 It does not explain new-onset dyskinesias in an adult with long-term antipsychotic use.

💠 The limbic system is the brain’s primary network for emotional regulation, explaining the client’s sudden anger, excessive crying, and inappropriate laughter.

💠 Key limbic structures such as the amygdala are responsible for emotional intensity and response, and dysfunction leads to poor emotional control.

💠 The hippocampus, another limbic structure, is essential for short-term and long-term memory formation and retrieval, accounting for the client’s memory difficulties.

💠 Motivation and drive are mediated through limbic pathways connected to reward and emotion, explaining apathy and reduced initiative.

💠 The absence of motor or coordination deficits supports involvement of an emotional–memory network rather than motor control centers.

Prefrontal Cortex

💠 The prefrontal cortex primarily governs executive function, judgment, and impulse control, not emotional expression itself.

💠 Isolated dysfunction would not fully explain significant memory impairment.

Cerebellum

💠 The cerebellum controls balance, coordination, and fine motor movement.

💠 Emotional and memory disturbances without motor deficits make cerebellar involvement unlikely.

Temporal Lobe

💠 The temporal lobe contributes to memory and auditory processing, but not comprehensive emotional regulation.

💠 The symptoms point to integrated emotional–memory dysfunction, best explained by the limbic system.

💠 SSRIs block the serotonin reuptake transporter (SERT) on the presynaptic neuron, preventing serotonin from being taken back up.

💠 This results in more serotonin remaining in the synaptic cleft, where it can continue to stimulate postsynaptic receptors.

💠 Enhanced serotonergic signaling improves mood, sleep, appetite, and emotional regulation over time.

💠 The primary effect is increased availability, not increased production or immediate receptor changes.

💠 Clinical improvement occurs after adaptive changes in neural signaling, explaining the delayed onset of therapeutic benefit.

SSRIs increase the production of serotonin within the presynaptic neuron

💠 SSRIs do not increase serotonin synthesis from tryptophan.

💠 Their action occurs after serotonin is released, not during production.

SSRIs block muscarinic and alpha-1 norepinephrine receptors to improve mood

💠 This mechanism is characteristic of tricyclic antidepressants, not SSRIs.

💠 SSRIs are selective for serotonin reuptake and avoid these receptor effects.

SSRIs cause an increase in the number of serotonin receptors at the postsynaptic terminal

💠 SSRIs do not directly increase receptor numbers.

💠 Any receptor adaptations are secondary and delayed, not the core mechanism.
