During a psychiatric assessment, the nurse observes a patient’s facial expression is without emotion. The patient says, "Life feels so hopeless to me. I've been feeling sad for several months." How will the nurse document the patient's affect and mood?

Choice A reason: Educating a patient in an acute manic state about hygiene is ineffective. During mania, patients experience significant distractibility and poor impulse control. They are cognitively unable to process or retain complex instructions regarding social norms or grooming until their mood is stabilized through pharmacological interventions.

Choice B reason: Increasing the dose without knowing the current serum concentration is dangerous. Lithium has a very narrow therapeutic index, typically between 0.6 and 1.2 mEq/L. Escalating the dose blindly could lead to lithium toxicity, which can cause permanent neurological damage, renal failure, or even death.

Choice C reason: Lithium 600 mg tid (1800 mg daily) is a robust dose that should typically produce a therapeutic effect within 7 days. If the patient is still showing acute manic symptoms like pressured speech and hyperactivity, the nurse must suspect non-adherence ("cheeking" the pills) or subtherapeutic serum levels.

Choice D reason: Monitoring and documentation are necessary nursing functions, but they do not address the underlying clinical problem. A patient who remains highly agitated after a week of high-dose lithium therapy requires an active intervention to determine why the medication is not producing the expected clinical response.

Choice A reason: While self-harm requires assessment, a superficial cut following an argument often represents a maladaptive coping mechanism rather than an imminent threat to life. If the patient is now stable and has a safety plan, they may be managed through outpatient crisis services rather than an inpatient bed.

Choice B reason: This patient is experiencing command hallucinations directed toward infanticide, representing an immediate and high-risk psychiatric emergency (postpartum psychosis). This situation requires immediate inpatient admission to ensure the safety of the infant and the parent, and to initiate intensive antipsychotic stabilization and monitoring.

Choice C reason: Dry mouth and tremors are common side effects of haloperidol (anticholinergic and extrapyramidal symptoms). These can usually be managed by adjusting the medication dosage or administering an anticholinergic like benztropine in the emergency department or an outpatient setting; they do not necessitate an acute psychiatric admission.

Choice D reason: Anxiety and sadness following a significant life event like a divorce are normal grief reactions. Unless the patient expresses active suicidal ideation with a plan or an inability to care for themselves, they are best served by community support groups or outpatient therapy rather than inpatient hospitalization.
