Which of the following interventions is most effective in managing a patient with obsessive-compulsive disorder (OCD)?

Correct Answer: B

Rationale: The most effective intervention in managing a patient with obsessive-compulsive disorder (OCD) is helping the patient to understand that their thoughts are irrational. This cognitive-behavioral approach can assist in reducing the frequency and intensity of obsessive thoughts and compulsive behaviors by challenging and reframing maladaptive beliefs and thought patterns associated with OCD. Encouraging the patient to engage in repetitive behaviors (choice A) reinforces the compulsive behavior rather than addressing the underlying issue. Providing a structured daily routine (choice C) may help in some cases but does not directly target the irrational thoughts and beliefs. Allowing the patient to avoid trigger situations (choice D) can provide temporary relief but does not address the core problem of irrational thoughts and behaviors.

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: B

Rationale: The correct answer is B. Taking medication regularly, even when feeling well, is crucial in managing bipolar disorder. Choice A is incorrect because medication adherence should not be based on symptoms alone. Choice C is incorrect as stopping medication due to side effects should be discussed with a healthcare provider. Choice D is incorrect because relying on memory may lead to missed doses, impacting treatment effectiveness.

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.
