After assessing the patient and formulating the nursing diagnoses for a plan of care, what is the next action a nurse should take?

Choice A reason: Histamine regulates wakefulness and allergic responses, not anxiety or fear. Its receptors in the brain promote alertness, but excessive histamine does not drive sympathetic activation like increased heart rate. This makes histamine an incorrect choice for the symptoms described, which align with autonomic arousal.

Choice B reason: Acetylcholine mediates parasympathetic responses, like slowing heart rate, not the sympathetic activation seen in anxiety. While it plays a role in attention, it does not primarily cause fear or tachycardia, making it an unsuitable choice compared to norepinephrine’s role in stress responses.

Choice C reason: GABA inhibits neural activity, reducing anxiety via GABA-A receptor activation. Low GABA levels may contribute to anxiety, but the symptoms described (tachycardia, fear) result from sympathetic activation, not GABA excess. This makes GABA incorrect for the neurotransmitter driving these symptoms.

Choice D reason: Norepinephrine, released during stress, activates the sympathetic nervous system, increasing heart rate and inducing fear via locus coeruleus activation. It heightens arousal in the amygdala, contributing to anxiety symptoms. This aligns with the fight-or-flight response, making norepinephrine the correct neurotransmitter for these symptoms.

Choice A reason: Socialization and mutual needs define social relationships, not therapeutic ones. Therapeutic relationships focus on patient needs, like addressing serotonin-driven depression, not reciprocal sharing. This approach risks blurring professional boundaries, making it incorrect for psychiatric nursing’s patient-centered focus.

Choice B reason: Mutual growth and satisfaction characterize social partnerships, not therapeutic relationships. In psychiatric care, the focus is on patient recovery, addressing issues like dopamine imbalances, not nurse satisfaction. This option misaligns with the professional, patient-centered nature of therapeutic relationships.

Choice C reason: The therapeutic relationship centers on the patient, addressing issues like amygdala-driven anxiety through collaborative discussion. Solutions, like medication adherence, are patient-driven to promote autonomy, aligning with neurobiological and psychological recovery principles, making this the correct description of the therapeutic dynamic.

Choice D reason: Shifting focus and mutual advice blur professional boundaries, resembling social relationships. Therapeutic relationships prioritize patient needs, like serotonin stabilization, with nurse guidance, not reciprocal advice. This option misrepresents the patient-centered, evidence-based nature of psychiatric therapeutic relationships.
