Correct Answer: A

Rationale: Corrected Rationale: Diarrhea is an early sign of lithium toxicity. When a client being treated with lithium presents with diarrhea, it can indicate the beginning of lithium toxicity. Monitoring for this symptom is crucial as it can progress to more severe toxicity if not addressed promptly. Tremors (choice B) are more commonly associated with the therapeutic effects of lithium rather than toxicity. Polyuria (choice C) is a common side effect of lithium, but it is not typically an early sign of toxicity. Blurred vision (choice D) is not a common early sign of lithium toxicity. Therefore, option A is the correct answer.

Correct Answer: B

Rationale: The correct answer is B: 'Tells when voices decrease.' This outcome indicates improvement because it shows that the client is experiencing a reduction in auditory hallucinations. By communicating that the voices are decreasing, it suggests that the client's symptoms are improving and the treatment is effective. Choices A, C, and D are incorrect. Arguing with the voices (A) indicates ongoing engagement with the hallucinations, which is not a positive outcome. Following what the voices say (C) suggests compliance with the hallucinations, which is not indicative of improvement. Lastly, telling the nurse what the voices say (D) does not necessarily demonstrate a reduction in hallucinations or improvement in the client's condition.

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: A

Rationale: The correct response is A: 'It is common for antidepressants to take several weeks to have an effect.' This response is appropriate because SSRI and other antidepressants often require several weeks to exhibit improvement in mood. It is crucial to educate the client about this delay to manage expectations and promote adherence to the medication regimen. Choice B is incorrect as switching medications prematurely is not typically recommended after just one week. Choice C is incorrect because it sets unrealistic expectations for immediate improvement. Choice D is incorrect as it may come across as accusatory and should not be the initial response.

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.
