Correct Answer: C

Rationale: The client is demonstrating symptoms of schizophrenia, such as disorganized speech that may include word salad (a type of communication that mixes real and imaginary words in no logical order), incoherent speech, and clanging (rhyming). Dementia (Choice A) is characterized by memory loss and cognitive decline, not by disorganized speech. Depression (Choice B) typically presents with persistent feelings of sadness and loss of interest, not disorganized speech. Chronic brain syndrome (Choice D) is a vague term and does not specifically describe the symptoms mentioned in the scenario.

Correct Answer: D

Rationale: Nausea and vomiting should be reported immediately because they could indicate lithium toxicity, which requires urgent medical attention to prevent more severe effects. Short-term memory loss, depressed affect, and weight gain are common side effects of lithium but do not require immediate medical attention compared to symptoms of toxicity like nausea and vomiting.

Correct Answer: B

Rationale: The correct answer is to assist the client with activities of daily living. This intervention is the most appropriate as it directly addresses the client's immediate needs by providing assistance with personal hygiene and dressing. It promotes self-care and ensures the client's well-being. Encouraging the client to take a shower (Choice A) may not be effective if the client is unable to do so independently due to their condition. Providing clean clothes (Choice C) is important but does not address the client's need for assistance with personal care. Explaining the importance of personal hygiene (Choice D) may not be as effective as providing direct assistance in this situation.

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: A

Rationale: Apathy, lack of energy, and lack of interest in daily activities are negative symptoms of schizophrenia (A). Positive symptoms of schizophrenia include hallucinations and delusions (B). While antipsychotic medication side effects can sometimes cause lethargy or sedation (C), the scenario specifically describes negative symptoms. Depression can also cause similar symptoms (D), but in the context of schizophrenia, these are recognized as negative symptoms.
