Several nurses are concerned that agency policies related to restraint and seclusion are inadequate. Which statement about the relationship of substandard institutional policies and individual nursing practice should guide nursing practice?
The policies do not absolve an individual nurse of the responsibility to practice according to professional standards of nursing care
In an institution with substandard policies, the nurse has a responsibility to inform the supervisor and leave the premises
Agency policies are the legal standard by which a professional nurse must act and therefore override other standards of care
Interpretation of policies by the judicial system is rendered on an individual basis and therefore cannot be predicted
The Correct Answer is A
Choice A reason: Nurses must adhere to professional standards, ensuring safe care despite substandard policies. Restraint use, for example, must minimize harm and respect patient dignity, regardless of policy. This aligns with ethical principles and evidence-based practices for managing agitation linked to neurotransmitter imbalances, upholding nurse accountability.
Choice B reason: Leaving the premises after informing a supervisor abandons patients, violating ethical duties. Professional standards require nurses to advocate for safe practices, like appropriate restraint use for dopamine-driven agitation, within the system. This option is impractical and neglects patient care responsibilities, making it incorrect.
Choice C reason: Agency policies do not override professional standards. Nurses are accountable to evidence-based practices, ensuring interventions like restraints for severe agitation are safe and ethical. Policies may guide but cannot excuse deviations from standards addressing neurobiological safety needs, making this option scientifically and ethically incorrect.
Choice D reason: Judicial interpretation varies, but nursing practice is guided by professional standards, not unpredictable legal outcomes. Standards ensure safe, ethical care, like minimizing restraint use for serotonin-related agitation, regardless of policy or judicial variability. This option is irrelevant to guiding daily nursing practice.

Correct Answer is D
Explanation
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 C
Explanation
Choice A reason: Prolonged silences may cause withdrawal in some patients, as anxiety from serotonin or GABA imbalances can heighten discomfort. However, this does not guide silence’s use. Silence is therapeutic when timed appropriately, not avoided due to potential withdrawal, making this principle incorrect.
Choice B reason: Nurses breaking silences assumes discomfort, ignoring therapeutic benefits. Silence allows processing, potentially calming amygdala hyperactivity in anxiety. The nurse’s role is to use silence strategically, not to interrupt it routinely, making this principle misaligned with effective interview techniques.
Choice C reason: Silence facilitates reflection, allowing patients to process emotions, reducing stress via hypothalamic calming. In disorders like depression, it supports cognitive restructuring by giving time to integrate thoughts. This principle guides therapeutic silence, aligning with neurobiological benefits of reflective pauses in interviews.
Choice D reason: Silence does not inherently confirm understanding. It may allow emotional processing, but assuming it signals comprehension risks miscommunication. In conditions like anxiety, silence supports reflection, not validation, making this principle less accurate than reflection for guiding its therapeutic use.
