A nurse is assessing a patient with schizophrenia who is experiencing delusions. Which intervention is most appropriate?

Correct Answer: C

Rationale: The most appropriate intervention when assessing a patient with schizophrenia experiencing delusions is to engage the patient in reality-based activities. This intervention helps distract the patient from the delusions and reorients them to the present, promoting grounding in reality. Choice A is incorrect because agreeing with delusions can reinforce them and hinder treatment. Choice B may exacerbate the delusions by delving deeper into their basis. Choice D may not be beneficial as it focuses solely on the delusions without addressing the need to ground the patient in reality.

Correct Answer: C

Rationale: Paroxetine is a selective serotonin reuptake inhibitor (SSRI) commonly prescribed for obsessive-compulsive disorder due to its efficacy in managing OCD symptoms. While different SSRIs may be used based on individual patient response and tolerability, Paroxetine stands out as a well-established option for treating OCD. Fluoxetine (Choice A) is another SSRI commonly used for OCD, but Paroxetine is more commonly associated with this indication. Citalopram (Choice B) and Escitalopram (Choice D) are also SSRIs but are not typically the first choice for treating OCD.

Correct Answer: B

Rationale: Excessive worry is a characteristic feature of generalized anxiety disorder (GAD). Patients with GAD experience persistent and excessive worry about various aspects of their life, such as work, health, or family, even when there is little or no reason for concern. This chronic worrying can significantly impact their daily functioning and quality of life. Flashbacks are more commonly associated with post-traumatic stress disorder (PTSD), hallucinations are more typical in conditions like schizophrenia, while compulsive behaviors are seen in obsessive-compulsive disorder (OCD). Therefore, in the context of GAD, excessive worry is the symptom that the nurse is most likely to observe.

Correct Answer: B

Rationale: Buspirone is often chosen as a first-line treatment for generalized anxiety disorder (GAD) due to its efficacy and favorable side effect profile. Unlike benzodiazepines such as clonazepam (A), buspirone does not carry the risk of tolerance, dependence, or withdrawal symptoms, making it a preferred choice. While propranolol (C) and hydroxyzine (D) are sometimes used for anxiety, they are not typically considered first-line treatments for GAD.

Correct Answer: C

Rationale: Patients prescribed MAOIs need to avoid consuming tyramine-rich foods as these can lead to hypertensive crises. Tyramine is found in various foods like aged cheeses, cured meats, some types of beer, and fermented products. Interactions between tyramine and MAOIs can result in severe hypertension, highlighting the importance of educating patients about dietary restrictions to ensure their safety. Choices A, B, and D are incorrect because high-protein foods, high-fiber foods, and low-fat foods do not pose a significant risk of hypertensive crises when taken with MAOIs. Therefore, the correct answer is C.

Correct Answer: C

Rationale: The correct answer is dopamine. Dopamine dysregulation is a key factor in the development of schizophrenia. Excess dopamine activity in certain brain regions is associated with positive symptoms of schizophrenia, such as hallucinations and delusions. Dopaminergic medications that reduce dopamine levels are often used to manage these symptoms, further supporting the role of dopamine in schizophrenia. Serotonin (Choice A) is more commonly associated with mood regulation and is implicated in depression and anxiety disorders. Norepinephrine (Choice B) is involved in the body's 'fight or flight' response and is linked to conditions like anxiety and PTSD. Acetylcholine (Choice D) plays a role in muscle movement and memory but is not primarily implicated in schizophrenia.

Correct Answer: C

Rationale: Delusions are considered a positive symptom of schizophrenia. Positive symptoms represent an excess or distortion of normal functions, such as hallucinations, delusions, or disorganized speech or behavior. In contrast, negative symptoms involve a decrease or absence of normal functions, like alogia (poverty of speech), anhedonia (inability to experience pleasure), and flat affect (reduced expression of emotions). Therefore, in the context of schizophrenia, delusions fall under the category of positive symptoms.

Correct Answer: A

Rationale: The most appropriate therapeutic approach for a patient diagnosed with borderline personality disorder exhibiting self-harming behavior is dialectical behavior therapy (DBT). DBT is specifically designed to address the core symptoms of borderline personality disorder, including self-harming behaviors. It focuses on teaching patients skills to manage emotions, improve interpersonal relationships, and enhance distress tolerance. Psychoanalysis (Choice B) is not the most appropriate for immediate symptom management in this case. Supportive therapy (Choice C) may not provide the structured approach needed to address self-harming behaviors effectively. Pharmacotherapy (Choice D) may be used as an adjunct in some cases, but DBT is the frontline therapy for managing self-harming behaviors in borderline personality disorder.

Correct Answer: C

Rationale: The correct answer is C, 'Sexual dysfunction.' Paroxetine, an SSRI commonly prescribed for OCD, can lead to sexual dysfunction as a side effect. Patients should be educated about this potential adverse effect to ensure they are aware and can seek appropriate management if needed. Choices A, B, and D are incorrect because insomnia, weight loss, and hypertension are not typically associated with paroxetine use as common side effects in patients with OCD.
