Correct Answer: B

Rationale: The best response for the LPN/LVN to provide to the wife of a male client diagnosed with schizophrenia is choice B: 'It is a chemical imbalance in the brain that causes disorganized thinking.' This response educates the wife about the nature of schizophrenia, explaining that it is caused by a chemical imbalance in the brain leading to disorganized thinking, helping her understand the condition better. Choice A does not directly address the question and instead shifts the focus to a different aspect. Choice C gives false reassurance without providing necessary information about schizophrenia. Choice D deflects the responsibility of providing information to the psychologist instead of addressing the wife's concerns directly.

Correct Answer: B

Rationale: Frequent urination and increased thirst can be signs of lithium toxicity, which can lead to serious complications if not addressed promptly. Assessing for signs of lithium toxicity is crucial to determine the client's condition and prevent further harm. Instructing the client to increase fluid intake (Choice A) may worsen the situation by exacerbating lithium toxicity. Suggesting the client reduce salt intake (Choice C) is not the priority when signs of toxicity are present. Notifying the healthcare provider immediately (Choice D) is important, but the initial action should be to assess the client for signs of lithium toxicity to provide immediate care.

Correct Answer: B

Rationale: Assisting the client in exploring feelings of shame, anger, and guilt (B) is the most appropriate intervention for acute depression as it helps address core emotions that may be contributing to the condition. Focusing on these emotions can aid the client in processing and coping with their feelings. Ensuring that the client's day is filled with group activities (A) might overwhelm the client, as they may not be ready for social interactions during this sensitive time. Allowing the client to initiate and determine activities of daily living (C) is more suitable for chronic cases where the client needs to regain autonomy. Encouraging the client to explore the rationale for his depression (D) is less effective in acute cases, as the focus should be on immediate emotional support and understanding rather than cognitive analysis.

Correct Answer: C

Rationale: The correct answer is to notify the healthcare provider of possible extrapyramidal symptoms (EPS). The symptoms described, such as a stiff, mask-like facial expression and difficulty speaking, are indicative of EPS, which can be a serious side effect of haloperidol. It is crucial to involve the healthcare provider immediately to address these symptoms. Administering a PRN dose of lorazepam (Choice A) is not the priority in this situation, as it does not address the underlying cause of EPS. Encouraging the client to perform facial exercises (Choice B) is not appropriate and may not effectively manage EPS. Documenting the findings and continuing to monitor the client (Choice D) is important but not the priority when potential EPS is present; immediate action by notifying the healthcare provider is essential.

Correct Answer: B

Rationale: The correct answer is B: 'Keep your dietary salt intake consistent.' Consistent salt intake is crucial when taking lithium carbonate to avoid lithium toxicity or ineffectiveness due to its renal excretion mechanism. Option A is incorrect because it focuses on the time to achieve therapeutic effects, which is important but not as critical as maintaining consistent salt intake. Option C is incorrect as it mentions avoiding aged cheese and chicken liver, which is more relevant for individuals taking MAOIs. Option D is incorrect as it suggests eating high-fiber foods, which is not directly related to lithium carbonate therapy.
