A patient with borderline personality disorder is admitted to the psychiatric unit. Which behavior is most characteristic of this disorder?

Correct Answer: B

Rationale: Borderline personality disorder is characterized by impulsivity and self-destructive behaviors, such as substance abuse, reckless driving, and self-harm. These behaviors are often used to cope with intense emotional distress and are a key feature of this disorder. While individuals with borderline personality disorder may also struggle with unstable relationships, the hallmark feature that sets it apart is the impulsivity and self-destructive behaviors. Avoiding social interactions due to fear of rejection is more characteristic of avoidant personality disorder. Having a grandiose sense of self-importance is a feature of narcissistic personality disorder.

Correct Answer: C

Rationale: Methylphenidate is the correct answer. It is a stimulant medication commonly used to treat ADHD. Methylphenidate works by increasing the activity of certain chemicals in the brain that are involved in attention and impulse control. Sertraline is an antidepressant used for depression, anxiety, and other conditions, not ADHD. Diazepam is a benzodiazepine mainly prescribed for anxiety, muscle spasms, and seizures, not ADHD. Clozapine is an antipsychotic medication used for schizophrenia when other medications are ineffective, not for ADHD.

Correct Answer: C

Rationale: As the patient transitions to maintenance therapy, the typical approach involves decreasing the dosage to a lower level. This adjustment is made to find the minimum effective dose needed for symptom control while reducing the potential side effects associated with long-term use. Choosing a higher dosage (A) would not align with the goal of maintenance therapy, as it may increase the risk of adverse effects. Once-a-week dosing (B) is not a common adjustment for lithium, which is usually prescribed daily for bipolar disorder. Switching to a different drug (D) is typically considered if the current medication is ineffective or intolerable, not as a routine step in transitioning to maintenance therapy.

Correct Answer: D

Rationale: This behavior of playacting as a police officer and 'locking up' other children to the point of causing fear may suggest that the child is displaying potential symptoms of traumatization. It could indicate that the child has experienced or witnessed traumatic events, leading to the replication of such scenarios as a coping mechanism or way to process the trauma. Choices A, B, and C are incorrect because the behavior described is more indicative of a potential trauma response rather than a need to dominate others, invent traumatic events, or develop close relationships.

Correct Answer: A

Rationale: Choice A is the correct answer as it emphasizes the importance of avoiding triggers like alcohol and caffeine that can lead to symptom relapse in patients with bipolar disorder. Educating the patient and their support system about these triggers is essential for managing the condition effectively and preventing exacerbations of symptoms. Choice B is incorrect as it overly focuses on antidepressant therapy, which is not the primary concern related to triggers for symptom relapse. Choice C, while important, does not directly address triggers for symptom relapse in bipolar disorder. Choice D is also relevant but does not provide immediate information on managing triggers for symptom relapse.
