A client is experiencing a panic attack. What medication will provide the quickest relief from acute severe anxiety symptoms?

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.

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.
