Correct Answer: A

Rationale: When educating a patient with hypertension about lifestyle modifications, reducing sodium intake is crucial as excess sodium can contribute to high blood pressure. While increasing physical activity is beneficial for overall health, it is not the primary lifestyle modification specifically targeted at hypertension. Quitting smoking and avoiding alcohol are important for general health but are not the first-line lifestyle modifications recommended for hypertension. Therefore, the correct answer is to reduce sodium intake.

Correct Answer: D

Rationale: The correct answer is D: 'You should avoid taking this medication with dairy products.' Ciprofloxacin should not be taken with dairy products as they can interfere with the absorption of the medication. Choice A is incorrect because ciprofloxacin should not be taken with antacids containing aluminum or magnesium. Choice B is incorrect as there is no specific limitation on caffeine intake associated with ciprofloxacin. Choice C is incorrect as ciprofloxacin does not typically cause urine to turn dark brown.

Correct Answer: A

Rationale: The correct answer is A: Monitor fluid balance and administer heparin. For a patient undergoing dialysis, it is crucial to monitor fluid balance to prevent fluid overload or depletion. Administering heparin helps prevent clot formation during the dialysis process. Option B is incorrect as while monitoring blood pressure is essential, preventing clot formation is more directly related to heparin administration. Option C is incorrect because administering medications and monitoring blood chemistry are not the primary interventions for dialysis. Option D is incorrect as while dietary education and protein intake are important for overall health, they are not the key nursing interventions specifically for a patient undergoing dialysis.

Correct Answer: A

Rationale: The correct answer is to check for air leaks in the tubing every 4 hours when caring for a client with a chest tube. This responsibility is crucial because it ensures proper chest tube function and helps prevent complications such as pneumothorax or hemothorax. Clamping the chest tube (Choice B) can lead to serious issues by causing a tension pneumothorax. Encouraging deep breathing and coughing (Choice C) is important for respiratory hygiene but is not directly related to chest tube care. Keeping the client in a high Fowler's position (Choice D) may be beneficial for some conditions but is not specific to chest tube management.

Correct Answer: D

Rationale: Checking the client's neurovascular status is the priority when caring for a client with severe pain after a leg fracture. This assessment is crucial to identify any signs of vascular compromise or nerve damage, such as compartment syndrome. Administering pain medication can help alleviate the pain but should only be done after ensuring the client's neurovascular status is stable. Repositioning or elevating the leg may worsen the condition if there are underlying vascular issues, making these options lower in priority than assessing neurovascular status.
