In a patient with bipolar disorder, which symptom would indicate a manic episode?

Correct Answer: C

Rationale: The correct answer is C: Decreased need for sleep. A decreased need for sleep is a hallmark symptom of a manic episode in bipolar disorder. During manic episodes, individuals may experience significantly reduced sleep without feeling tired, which can lead to increased energy levels, impulsivity, and other manic symptoms. Excessive sleeping (choice A) is more indicative of depression rather than mania. Low self-esteem (choice B) and anhedonia (choice D) are also more commonly associated with depressive episodes rather than manic episodes in bipolar disorder.

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: The correct answer is B: Regular blood tests are crucial when taking valproic acid to monitor the medication levels in the bloodstream. This monitoring helps ensure that the patient is receiving the correct dosage for effective treatment and to prevent adverse effects associated with either subtherapeutic or toxic levels of the medication. Choice A is incorrect because there is no specific interaction between valproic acid and dairy products. Choice C is incorrect as valproic acid can generally be taken with food to reduce gastrointestinal side effects. Choice D is incorrect as abruptly stopping valproic acid can lead to withdrawal symptoms and worsening of the condition.

Correct Answer: A

Rationale: Deep breathing exercises are a widely recommended technique for managing anxiety and promoting relaxation. By focusing on deep, slow breaths, individuals can activate the body's relaxation response, leading to decreased anxiety levels and an overall sense of calm. This technique is easy to learn, can be practiced anywhere, and is often suggested by healthcare professionals as a first-line approach for anxiety management. Physical exercise, mindfulness meditation, and journaling are also beneficial for mental well-being but may not be the first choice when specifically targeting acute anxiety management.

Correct Answer: C

Rationale: During a severe anxiety episode, it's crucial to stay with the patient and create a quiet environment. This approach helps reduce anxiety by providing a sense of safety and support. Encouraging the patient to talk about their feelings may not be effective during an acute episode of severe anxiety. Using a firm, authoritative approach can escalate the situation and worsen the anxiety. Suggesting distractions like watching TV may not address the root cause of the anxiety or provide the necessary support.

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: 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: B

Rationale: During a manic episode, individuals may experience heightened energy levels and reduced impulse control. Providing a structured environment with limited stimuli is the most appropriate nursing intervention. This approach helps reduce excessive stimulation and potential triggers for further escalation of manic behavior. It promotes a calming and controlled setting, assisting in managing symptoms and promoting the patient's well-being. Encouraging group activities (Choice A) may lead to overstimulation, allowing the patient to engage in physical activities freely (Choice C) could be risky due to impulsivity, and giving detailed tasks (Choice D) might overwhelm the individual.

Correct Answer: C

Rationale: The most appropriate goal of cognitive-behavioral therapy (CBT) in treating generalized anxiety disorder (GAD) is to change the patient's negative thought patterns. This therapy focuses on identifying and modifying distorted thinking patterns that contribute to anxiety. Exploring childhood experiences (Choice A) may be part of therapy, but the primary focus is on present thoughts and behaviors. While medication (Choice B) can help manage symptoms, CBT aims to address the root cause through cognitive restructuring. Improving social skills (Choice D) is not the primary goal of CBT for GAD, although it may be a secondary benefit as confidence improves with reduced anxiety.
