Correct Answer: C

Rationale: The correct answer is C. Obsessions do not cause compulsions; rather, obsessions are intrusive, unwanted thoughts, images, or urges that trigger intensely distressing feelings, while compulsions are repetitive behaviors or mental acts that a person feels driven to perform in response to an obsession or according to rules that must be applied rigidly. Choices A, B, and D are incorrect. Choice A is incorrect because compulsions are behaviors or mental acts aimed at reducing distress or preventing a dreaded event or situation. Choice B is incorrect because while anxiety is often a significant component of OCD, it is not the only reason for the disorder. Choice D is incorrect because obsessive thoughts are not solely linked to levels of neurochemicals but are more complex and multifactorial.

Correct Answer: C

Rationale: The correct answer is (C) projecting her feelings onto the nurse. The mother's behavior suggests that she is attributing her own actions or feelings to the nurse, which is a form of projection. Option (A) regressing to an earlier behavior pattern is not the best fit in this context. Option (B) sublimating her anger is not applicable based on the given scenario. Option (D) suppressing her fear cannot be inferred from the provided information.

Correct Answer: B

Rationale: The correct answer is B because SSRIs like fluoxetine typically take several weeks to reach their full therapeutic effect, so it's important to set realistic expectations for the client. Choice A is incorrect as dizziness is a common side effect but not the most important teaching point. Choice C is incorrect as avoiding tyramine-rich foods is more relevant for MAOIs. Choice D is incorrect as fluoxetine should be taken consistently, not only when the client feels depressed, to maintain therapeutic blood levels.

Correct Answer: D

Rationale: For a severely depressed client with neurovegetative symptoms, the care plan should include rest, simple communication, suicide precautions, monitoring intake, and encouraging mild exercise. Limiting and discouraging food and fluid intake is not appropriate as proper nutrition and hydration are essential for overall well-being. This choice could lead to further complications and is not recommended in the care of a depressed client.

Correct Answer: A

Rationale: In a situation where a client is displaying aggression and agitation, the immediate priority of care for the nurse is to ensure safety for the client and others on the unit. Providing a safe environment and implementing calming measures take precedence over other interventions. Option A is the correct choice as it addresses the crucial need for safety in a potentially volatile situation. Options B, C, and D, although important, do not address the primary concern of ensuring safety for all individuals involved.
