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: A

Rationale: Encouraging deep, slow breathing is the most appropriate intervention for a patient experiencing a panic attack. This technique can help the patient regulate their breathing, reduce hyperventilation, and promote relaxation, which are essential in managing the symptoms of a panic attack. Choice B, encouraging the patient to talk about their feelings, may not be effective during an acute panic attack as the focus should be on calming the patient down. Choice C, leaving the patient alone, can lead to increased feelings of fear and isolation during a panic attack. Choice D, engaging the patient in physical activity, may exacerbate symptoms as it can increase the feeling of being out of control.

Correct Answer: B

Rationale: Patients prescribed sertraline for major depressive disorder should be educated that it may take several weeks before experiencing the full therapeutic effects of the medication. This delay in onset of action is common with antidepressants like sertraline, and patients need to be aware of this to manage their expectations and continue with the treatment regimen. It's important for the patient to understand that consistent adherence to the prescribed dosage is crucial, even if the full effects are not immediately apparent. Choices A, C, and D are incorrect because taking the medication with food, avoiding grapefruit, and regular blood tests are not specific education points related to the expected timeframe for therapeutic effects of sertraline.

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: Engaging the patient in a reality-based activity is the most appropriate intervention for a patient with schizophrenia experiencing hallucinations. This intervention can help distract the patient from the hallucinations and reorient them to the present, promoting a connection with reality and potentially reducing distress associated with the hallucinations. Choice A, encouraging the patient to ignore the voices, may not be effective as it can be challenging for the patient to dismiss the hallucinations. Choice C, providing a quiet environment, is helpful but may not directly address the hallucinations. Choice D, asking the patient to describe the hallucinations in detail, may increase the patient's focus on the hallucinations, potentially worsening distress.
