Correct Answer: B

Rationale: The correct intervention for a client with bulimia nervosa is to observe the client for 30 minutes after meals. This helps prevent purging behaviors, such as vomiting or using laxatives, which are common in bulimia nervosa. Choice A is incorrect because eating meals alone may enable the client to engage in purging behaviors without being observed. Choice C is incorrect as a high-calorie diet may exacerbate the client's concerns about weight gain. Choice D is incorrect because encouraging daily weigh-ins can reinforce obsessive thoughts about weight and body image.

Correct Answer: C

Rationale: The correct question to ask when assessing a client's perception of the precipitating event that led to a crisis is 'What leads you to seek help now?' This question directly addresses the client's current situation and triggers that brought them to seek assistance. Choices A and B are more focused on the client's social support system rather than the root cause of the crisis. Choice D addresses coping mechanisms rather than the actual trigger for seeking help.

Correct Answer: C

Rationale: (C) is the correct approach in this situation as it reinforces unit rules, setting clear boundaries and expectations. By reminding the client of the unit rules, the nurse is helping to maintain a safe and structured environment within the drug rehabilitation unit. (A) is unnecessary since the client's behavior does not warrant immediate physical intervention. (B) is not ideal because the client's privileges have already been explained, and suggesting he speak to his healthcare provider may not address the immediate issue. (D) is not appropriate as addressing inappropriate behavior is essential in a therapeutic setting.

Correct Answer: A

Rationale: In this situation, the best intervention for the nurse to implement is to move the client to a quiet area and provide peanut butter with crackers. The client's behavior indicates increasing agitation and loudness, which could be exacerbated by a noisy environment. Providing a quiet space can help reduce stimuli and promote a sense of calm. Additionally, offering a small, manageable snack like peanut butter with crackers can address the client's immediate needs for sustenance without overwhelming him. Choices B, C, and D do not address the client's current agitation and lack of sleep or food effectively, making them less appropriate interventions in this scenario.

Correct Answer: C

Rationale: The correct answer is C: 'Was physically abused by his mother.' A history of physical abuse can lead to heightened responses to physical contact. In this scenario, the employee's reaction of becoming very angry and swinging at the female employee after being pushed may be influenced by past experiences of physical abuse. This history can contribute to increased sensitivity to physical interactions and may trigger defensive or aggressive responses. Choices A, B, and D are less directly related to the employee's reaction in this specific context. While worrying about losing his job to a woman could contribute to underlying stress or insecurity, torturing animals as a child reflects a different type of behavioral issue, and hating to be touched by anyone suggests personal boundaries unrelated to the observed behavior in this scenario.
