Correct Answer: D

Rationale: Experiencing intrusive thoughts about a traumatic event, such as a plane crash, that occur unexpectedly and repeatedly is a common symptom of Post-Traumatic Stress Disorder (PTSD). These thoughts can be distressing and are often a key indicator of PTSD. Options A, B, and C demonstrate coping mechanisms and fears related to the traumatic event but do not specifically address the hallmark symptom of intrusive thoughts. Therefore, option D is the correct choice as it aligns with a potential symptom of PTSD.

Correct Answer: D

Rationale: In this scenario, the symptoms of apathy, avolition, and blunted affect are indicative of negative symptoms commonly seen in schizophrenia. These symptoms are often associated with dopamine and serotonin imbalances in the brain. Olanzapine, an atypical antipsychotic, is known for its efficacy in treating both positive and negative symptoms of schizophrenia. It acts by blocking serotonin and dopamine receptors, helping to alleviate the symptoms mentioned. Chlorpromazine and Haloperidol are typical antipsychotics that primarily target dopamine receptors, while Phenelzine is an MAOI used to treat depression and anxiety disorders, not schizophrenia. Therefore, the most appropriate choice for this client displaying these symptoms related to serotonin excess would be Olanzapine.

Correct Answer: B

While it may help calm an individual, it is not typically the first-line choice for managing acute agitation in a psychotic client. Haloperidol, on the other hand, is a typical antipsychotic medication often used for immediate intervention in psychiatric emergencies involving aggression or psychosis.
