A patient diagnosed with schizophrenia had an exacerbation of hallucinations and delusions related to medication non-adherence and was hospitalized for 10 days. The patient is stabilized and discharge is planned. The patient’s family is concerned that the patient’s symptoms will return after discharge. Acting as an advocate for the patient’s rights, the nurse’s best response is:

Choice A reason: Justice ensures fair treatment across patients. Different interventions (restraint vs. supervision) for self-mutilation, possibly due to serotonin dysregulation, must be equitably applied based on clinical need, not bias. Ensuring consistent, fair application of interventions aligns with justice, addressing ethical concerns about differential treatment in psychiatric care.

Choice B reason: Autonomy involves respecting patient choices, but self-mutilation, driven by impulsivity or emotional dysregulation, requires safety interventions overriding choice. Restraint and supervision prioritize safety over autonomy, making this principle less relevant than justice, which focuses on equitable treatment across patients in this scenario.

Choice C reason: Fidelity emphasizes keeping promises or loyalty to patients, not the fairness of intervention choices. While trust is crucial, the concern here is equitable treatment for self-mutilation, not commitment to promises. Fidelity is secondary to justice in addressing differential interventions, making it incorrect.

Choice D reason: Beneficence focuses on doing good, like preventing harm in self-mutilation. Both restraint and supervision aim to protect, but the ethical concern is fairness, not benefit. Justice addresses equitable application of interventions, making beneficence less directly applicable to the ethical dilemma described.

Choice A reason: Serotonin acts on 5-HT receptors, not muscarinic or nicotinic subtypes. It modulates mood and behavior but lacks the receptor diversity of acetylcholine. Serotonin’s receptors are G-protein-coupled or ligand-gated, unrelated to muscarinic or nicotinic mechanisms, making it incorrect for this neurotransmitter classification.

Choice B reason: Acetylcholine binds to muscarinic (G-protein-coupled) and nicotinic (ligand-gated) receptors. Muscarinic receptors regulate parasympathetic functions like heart rate, while nicotinic receptors mediate muscle contraction and CNS signaling. This dual receptor system is unique to acetylcholine, making it the correct neurotransmitter for this question.

Choice C reason: Dopamine acts on D1 and D2 receptors, not muscarinic or nicotinic subtypes. It regulates reward and motor functions but lacks the cholinergic receptor classifications. Dopamine’s receptors are G-protein-coupled, not ligand-gated like nicotinic, making it an incorrect choice for this neurotransmitter property.

Choice D reason: GABA binds to GABA-A (ligand-gated) and GABA-B (G-protein-coupled) receptors, not muscarinic or nicotinic. It inhibits neural activity, unrelated to cholinergic systems. GABA’s receptors mediate inhibitory signaling, not the excitatory or parasympathetic functions of muscarinic/nicotinic receptors, rendering it incorrect for this question.
