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: Asking about faith in stress assesses coping strategies, as faith can modulate stress responses via the hypothalamic-pituitary-adrenal axis, reducing cortisol levels. This explores psychological resilience, not just religious beliefs, aligning with holistic assessment of how patients manage stressors impacting mental health.
Choice B reason: Religious affiliation focuses on specific beliefs or denominations, not their role in stress management. The question targets coping, not affiliation details. Faith’s impact on stress involves neurobiological calming effects, making this option too narrow and incorrect for the assessment topic.
Choice C reason: Educational background is unrelated to faith’s role in stress. Coping involves psychological and neurobiological mechanisms, like serotonin modulation, not academic history. The question assesses emotional resilience, not education, making this option irrelevant to the described assessment focus.
Choice D reason: Culture includes broader societal norms, not specifically faith’s role in coping. While faith may be cultural, the question targets stress management, linked to neurobiological stress responses, not cultural identity. Coping strategies is the more precise assessment topic, making culture incorrect.
Correct Answer is D
Explanation
Choice A reason: A trusting relationship is the goal of therapeutic alliances, not countertransference. It reflects effective communication, calming amygdala-driven distress in suicidal patients. This is a normal outcome, not an emotional overreaction, making it an incorrect indicator of countertransference in psychiatric care.
Choice B reason: The patient comparing the nurse to parents suggests transference, not countertransference. Transference involves patient projections, often tied to past emotional patterns, not nurse emotions. This is unrelated to the nurse’s feelings, making it an incorrect choice for countertransference concerns.
Choice C reason: Realistic patient reactions indicate a healthy therapeutic dynamic, not countertransference. Appropriate responses align with stabilizing neurobiological states, like serotonin balance in depression. This reflects effective care, not nurse emotional overinvolvement, making it an incorrect indicator of countertransference in this context.
Choice D reason: Extreme happiness tied to the patient’s mood improvement suggests countertransference, where the nurse’s emotions, possibly influenced by mirror neuron activation, overly align with the patient’s state. This indicates personal overinvolvement, risking bias in care for suicidal patients with serotonin imbalances, making it the correct choice.
