Correct Answer: A

Rationale: The correct answer is to elevate the head of the bed. Elevating the head of the bed is crucial in improving oxygenation in clients with congestive heart failure and shortness of breath by reducing venous return to the heart and decreasing fluid overload in the lungs. This intervention helps to alleviate the client's breathing difficulty. Administering diuretic therapy (Choice B) may be necessary but is not the initial priority. Monitoring oxygen saturation (Choice C) is important but should come after ensuring proper positioning. Assessing the client's level of consciousness (Choice D) is essential but is not the first intervention needed for a client experiencing respiratory distress.

Correct Answer: C

Rationale: After a partial thyroidectomy, the client may be advised to avoid eating seafood due to its high iodine content, which can affect the thyroid function. Choice A is incorrect because after a partial thyroidectomy, supplemental hormonal therapy may be necessary. Choice B is incorrect as the thyroid does not regenerate after a partial thyroidectomy. Choice D is incorrect; the remaining portion of the thyroid is not typically removed at a later date unless there are specific medical reasons to do so.

Correct Answer: B

Rationale: The correct answer is B. Immediate evaluation by the surgeon is necessary due to the possibility of an internal hemorrhage, which is a life-threatening condition. Choice A is incorrect as lung status and oxygen saturation are not the priority in this situation. Choice C is not relevant to the current urgent issue. Choice D, while providing additional history, is not pertinent to the immediate concern of a potential internal hemorrhage post angioplasty and stent placement.

Correct Answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

Correct Answer: B

Rationale: The correct answer is to administer thiamine as prescribed. This intervention is a priority for clients with chronic alcoholism to prevent Wernicke's encephalopathy, a serious complication of thiamine deficiency. Monitoring for signs of alcohol withdrawal (choice A) is important but not the priority in this scenario. Providing a quiet environment (choice C) may be beneficial but does not address the immediate need to prevent Wernicke's encephalopathy. Initiating fall precautions (choice D) is also important but not the priority compared to administering thiamine to prevent a life-threatening condition.
