A patient presents with anxiety, increased heart rate, and fear. The nurse suspects the activation of which neurotransmitter?
Histamine
Acetylcholine
GABA
Norepinephrine
The Correct Answer is D
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.

Correct Answer is A
Explanation
Choice A reason: Sullivan’s interpersonal theory emphasizes therapeutic relationships and social environments to foster mental health. The therapeutic milieu, structured to promote safety and interaction, aligns with Sullivan’s focus on interpersonal dynamics, reducing symptoms like anxiety through supportive settings, which stabilize neurotransmitter imbalances, enhancing patient recovery on psychiatric units.
Choice B reason: Sullivan’s theory does not focus on age-appropriate versus arrested behaviors. It emphasizes interpersonal relationships, not developmental stages. Assessment tools for behavior typically rely on other frameworks, like Erikson’s, which address developmental milestones, not Sullivan’s interpersonal model, making this option scientifically inaccurate for the theory’s application.
Choice C reason: Restraint and seclusion are not part of Sullivan’s theory, which promotes therapeutic relationships to reduce anxiety, not coercive measures. These interventions contradict Sullivan’s focus on supportive environments, as they may exacerbate stress and neurotransmitter dysregulation, such as increased cortisol, worsening mental health outcomes in psychiatric settings.
Choice D reason: The nursing process is a general framework, not specific to Sullivan’s theory. Sullivan’s interpersonal model focuses on relationships to alleviate symptoms, not on sequencing nursing actions. While the nursing process guides care, it is not derived from Sullivan’s principles, making this option unrelated to his theoretical application.
Correct Answer is A
Explanation
Choice A reason: After diagnosis, setting goals and outcomes guides care, addressing issues like serotonin-driven depression. Goals, like “improve mood stability,” align with neurobiological needs, ensuring measurable, patient-centered targets. This step precedes interventions, forming the foundation for effective psychiatric treatment planning.
Choice B reason: Designing interventions follows goal-setting. Interventions, like therapy for dopamine imbalances, are based on established outcomes. Acting prematurely without goals risks misaligned care, as neurobiological targets must be defined first, making this step incorrect as the immediate next action.
Choice C reason: Implementation occurs after goals and interventions are set. Acting before defining outcomes, like stabilizing GABA for anxiety, risks ineffective care. The nursing process requires sequential planning to address neurobiological deficits, making implementation premature and incorrect at this stage.
Choice D reason: Spiritual assessment, while valuable, is part of initial data collection, not the next step after diagnosis. Goals addressing neurobiological issues, like serotonin deficits, take precedence to ensure targeted care. This option is irrelevant to the immediate planning phase of the nursing process.
