A nurse is educating a client starting on risperidone. Which of the following statements best explains the unique pharmacological action of second-generation antipsychotics compared to first-generation antipsychotics?
They enhance dopamine transmission to improve cognitive function in schizophrenia.
They block dopamine and serotonin receptors, reducing extrapyramidal side effects.
They primarily block dopamine D2 receptors, leading to high rates of extrapyramidal symptoms.
They selectively block only serotonin receptors, improving mood without affecting dopamine.
The Correct Answer is B
Choice A reason: Enhancing dopamine transmission is not the mechanism of antipsychotics; excessive dopamine is implicated in schizophrenia’s positive symptoms, so reducing—not enhancing—dopamine activity is key.
Choice B reason: Blocking both dopamine and serotonin receptors is characteristic of second-generation (atypical) antipsychotics. This dual action reduces extrapyramidal side effects while still targeting positive and negative symptoms.
Choice C reason: First-generation antipsychotics primarily block dopamine D2 receptors, which increases the risk for extrapyramidal side effects such as dystonia and parkinsonism.
Choice D reason: Selective serotonin receptor blockade is not the defining mechanism of second-generation antipsychotics. These medications act on both dopamine and serotonin systems.

Correct Answer is B
Explanation
Choice A reason: Sedative medications may be used in severe cases, but immediate nursing care focuses on nonpharmacologic interventions to ensure safety and reduce stimulation. Medication is not the first-line action.
Choice B reason: Providing a calm environment with reduced external stimuli while encouraging expression of feelings helps the client regain control and decreases anxiety during a panic episode. This is the most appropriate nursing intervention.
Choice C reason: Detailed problem-solving requires higher-level cognitive functioning, which is impaired during a panic attack. Attempting this intervention may increase the client’s distress.
Choice D reason: Allowing expression without guidance offers no therapeutic support and may leave the client overwhelmed by panic symptoms, prolonging the episode.
Correct Answer is ["B","D","E"]
Explanation
Choice A reason: Sharing personal loss shifts the focus away from the patient, which is not therapeutic. Self-disclosure in this way can hinder supportive communication.
Choice B reason: Suggesting a grief support group acknowledges the patient’s feelings while offering a constructive coping resource. It validates distress and provides support.
Choice C reason: Leaving the patient when they are emotionally vulnerable conveys abandonment instead of support, which is not therapeutic.
Choice D reason: Normalizing grief as a process that takes time offers reassurance without minimizing the client’s emotions. It helps the patient understand that healing is gradual.
Choice E reason: Encouraging the patient to share coping strategies promotes expression of feelings and helps the nurse assess adaptive versus maladaptive coping mechanisms.
