Correct Answer: A

Rationale: The correct answer is to confirm the client's perception of the event. In crisis intervention, understanding the client's perspective is crucial as it helps the nurse assess the situation accurately and provide tailored support. This step can also help build rapport and trust with the client. Option B, notifying the client's support system, may be important but should come after assessing the client's perception. Option C, helping the client identify personal strengths, and option D, teaching relaxation techniques, are valuable interventions but should follow the initial step of confirming the client's perception.

Correct Answer: A

Rationale: Corrected Rationale: Applying heat to inflamed joints can help relieve pain in clients with osteoarthritis. Heat therapy can help improve blood circulation, relax muscles, and reduce stiffness. Choice B, providing passive range-of-motion exercises, may be beneficial for joint mobility but is not the first-line intervention for pain relief in osteoarthritis. Choice C, encouraging prolonged use of NSAIDs, should be done cautiously due to potential side effects and should be guided by a healthcare provider. Choice D, applying cold packs to the joints, is not recommended for osteoarthritis as cold therapy can worsen stiffness and discomfort in this condition.

Correct Answer: B

Rationale: The correct intervention for a client exhibiting extrapyramidal symptoms while taking haloperidol is to administer benztropine. Benztropine is an anticholinergic medication commonly used to manage extrapyramidal symptoms caused by antipsychotic medications like haloperidol. Increasing the dose of haloperidol (Choice A) would exacerbate the symptoms rather than alleviate them. Administering naloxone (Choice C) is not indicated for extrapyramidal symptoms. Monitoring blood pressure (Choice D) is important but not the primary intervention for managing extrapyramidal symptoms.

Correct Answer: A

Rationale: The correct answer is A. Weight loss of 0.5 kg (1.1 lb) in 24 hours is an indication that furosemide is effectively reducing fluid retention. This medication works by promoting diuresis, resulting in increased urine output, which could lead to weight loss. While increased urinary output (choice B) is a common effect of furosemide, weight loss is a more specific indicator of its effectiveness. Blood pressure (choice C) and decreased peripheral edema (choice D) can be influenced by various factors and are not direct indicators of furosemide's effectiveness in reducing fluid retention.

Correct Answer: B

Rationale: The correct answer is B. When taking ferrous sulfate, clients should expect their stools to turn black, which is a normal side effect due to the iron content. Choice A is incorrect because ferrous sulfate should not be taken with milk as it can decrease its absorption. Choice C is incorrect because vitamin C-rich foods like oranges can actually enhance the absorption of iron. Choice D is incorrect because ferrous sulfate is usually recommended to be taken on an empty stomach for better absorption.
