Correct Answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

Correct Answer: B

Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.

Correct Answer: A

Rationale: Monitoring urine output and ensuring proper catheter drainage are crucial aspects of managing a patient with an indwelling urinary catheter. This helps in assessing the patient's renal function, fluid balance, and the patency of the catheter. Administering antibiotics and changing the catheter regularly (Choice B) may not be necessary unless there is an infection present. While monitoring for signs of infection and providing catheter care (Choice C) are important, the primary focus should be on urine output and drainage. Providing a high-sodium diet and monitoring hydration (Choice D) are not directly related to managing an indwelling urinary catheter.

Correct Answer: B

Rationale: The correct answer is B because avoiding perfumed lotions is important to prevent skin irritation after radiation therapy. Using a heating pad (A) can further damage the skin, applying cold compresses (C) may not be recommended, and scrubbing the area daily with soap and water (D) can be too harsh on the skin, leading to further irritation and damage.

Correct Answer: A

Rationale: The correct answer is A: A history of gastrointestinal bleeding. Patients with a history of gastrointestinal bleeding are at increased risk of complications when taking aspirin due to its effects on platelet function and the gastrointestinal tract. Reporting this finding to the provider is crucial to ensure patient safety. Choices B, C, and D are not directly related to the increased risk associated with aspirin use in patients with a history of gastrointestinal bleeding, making them less relevant in this scenario. While monitoring platelet count and PT are important in patients taking aspirin, a history of gastrointestinal bleeding takes precedence as it directly impacts the safety and effectiveness of aspirin therapy in this client.
