A client is newly prescribed a medication that will block the effects of histamine for the treatment of a mental health disorder. The client asks, “What side effects should I anticipate with this new medication?” Which response by the nurse is accurate?

Choice A reason: Projection involves attributing one’s issues to others, not ignoring symptoms. The patient’s dismissal of serious symptoms, like weight loss, suggests denial, not projection. These symptoms may indicate physiological issues, not psychological attribution, making projection incorrect for this defense mechanism.

Choice B reason: Regression involves reverting to childish behaviors, not ignoring symptoms. The patient’s claim of a minor cold despite weight loss and fatigue reflects denial, not regression. These symptoms suggest a serious condition, not immature coping, making this an incorrect defense mechanism.

Choice C reason: Denial involves refusing to acknowledge serious symptoms, like weight loss and fatigue, which may indicate a medical condition. By attributing them to a minor cold, the patient avoids reality, a common defense in stress-related cortisol spikes, making this the correct mechanism.

Choice D reason: Displacement redirects emotions to another target, not ignoring symptoms. The patient’s minimization of serious health issues, like fatigue, reflects denial, not redirected feelings. This mechanism is unrelated to dismissing physical symptoms, making it incorrect for the described behavior.

Choice A reason: Labeling paranoia as a loss of reality, while accurate for dopamine-driven delusions, risks alienating the patient. Confronting beliefs directly can increase agitation, as the amygdala amplifies fear responses. A therapeutic response validates emotions, not challenges perceptions, making this less effective.

Choice B reason: Acknowledging privacy concerns validates the patient’s emotions without reinforcing delusions. This reduces anxiety, calming amygdala hyperactivity in paranoia, and builds trust. By focusing on feelings, not the delusion’s content, the nurse fosters a therapeutic alliance, aligning with evidence-based approaches for psychotic disorders.

Choice C reason: Stating government prohibition addresses the delusion’s content, potentially escalating agitation. Paranoia, driven by mesolimbic dopamine excess, resists factual correction. This risks confrontation, undermining trust and therapeutic rapport, making it less effective than validating emotions in managing psychotic symptoms.

Choice D reason: Redirecting to another topic avoids engaging with the patient’s emotional state, missing a therapeutic opportunity. Paranoia, linked to dopamine dysregulation, requires addressing underlying fears to reduce amygdala-driven anxiety. Ignoring the concern can increase mistrust, making this response less therapeutic.
