A client diagnosed with major depressive disorder asks, “What part of my brain controls my emotions?” Which nursing response is appropriate?

The occipital lobe governs perceptions, judging them as positive or negative

The medulla regulates key biological and psychological activities

The limbic system is largely responsible for one’s emotional state

The parietal lobe has been linked to depression

Answer and Explanation

The Correct Answer is C

Choice A reason: The occipital lobe primarily processes visual information, not emotions. It interprets visual stimuli but does not judge them as positive or negative, which is a function of the limbic system. This makes the statement incorrect for explaining the brain’s role in emotional regulation.

Choice B reason: The medulla oblongata regulates vital functions like heart rate and breathing, not psychological activities or emotions. Emotional regulation involves higher brain structures like the limbic system, making this statement inaccurate for addressing the client’s question about emotions.

Choice C reason: The limbic system, including the amygdala and hippocampus, regulates emotions by processing fear, pleasure, and memory. It modulates emotional responses via neurotransmitter pathways and is implicated in depression, making this the correct and most accurate response to the client’s question.

Choice D reason: The parietal lobe processes sensory information and spatial awareness, not emotions. While depression may involve broader brain dysfunction, the parietal lobe is not primarily linked to emotional regulation, making this statement incorrect compared to the limbic system’s role.

Correct Answer is B

Explanation

Choice A reason: Continuing suctioning during decreased oxygen saturation and bradycardia worsens hypoxia, as suctioning removes oxygen from the airway. Administering 50% oxygen is insufficient to rapidly correct severe desaturation, making this action inappropriate compared to stopping suctioning and providing 100% oxygen.

Choice B reason: Discontinuing suctioning prevents further oxygen depletion, as suctioning removes air from the airway, exacerbating hypoxia. Administering 100% oxygen rapidly restores oxygen saturation, addressing bradycardia caused by hypoxemia. This aligns with critical care protocols, making it the best action.

Choice C reason: Preparing for resuscitation is premature unless the patient is unresponsive or in cardiac arrest. Decreased oxygen saturation and bradycardia can often be reversed by stopping suctioning and providing oxygen, making this action less immediate than addressing hypoxia directly.

Choice D reason: Continuing suctioning worsens hypoxia, and epinephrine is not indicated for bradycardia caused by suctioning-related hypoxemia. Epinephrine is used in cardiac arrest or allergic reactions, not routine suctioning complications, making this choice incorrect for the scenario.

A. I am just so sad. I cannot believe that my partner is gone B. I just cannot remember anything about the accident C. I don’t want to think or talk about what happened with anyone D. If I wasn’t such a bad person, this never would have happened

Correct Answer is C

Explanation

Choice A reason: Expressing sadness about the partner’s death reflects grief, not avoidance. Avoidance involves actively suppressing thoughts or discussions about the trauma. This statement indicates emotional processing, not avoidance, making it incorrect for identifying avoidance symptoms in this context.

Choice B reason: Inability to recall the accident may suggest dissociative amnesia, a potential trauma response, but it is not a clear avoidance symptom. Avoidance involves conscious efforts to avoid trauma-related stimuli, not memory loss, making this choice less precise than active refusal to discuss.

Choice C reason: Refusing to think or talk about the accident is a hallmark of avoidance symptoms in post-traumatic stress disorder (PTSD). This behavior reflects deliberate efforts to suppress trauma-related thoughts or conversations to reduce distress, aligning with the scenario, making this the correct choice.

Choice D reason: Blaming oneself for the accident reflects guilt or negative self-perception, common in PTSD, but is not an avoidance symptom. Avoidance involves dodging trauma-related stimuli, not internalizing blame, making this choice incorrect for identifying avoidance behaviors.
