Correct Answer: B

Rationale: Reducing sodium intake is crucial for managing hypertension as excess sodium can lead to increased blood pressure. High-fat foods (Choice A) are not recommended as they can contribute to heart issues. While dairy products (Choice C) should be consumed in moderation, they are not specifically targeted in hypertension management. High-protein foods (Choice D) are not the priority; rather, reducing sodium intake takes precedence due to its direct impact on blood pressure levels.

Correct Answer: A

Rationale: The priority for the nurse when caring for a patient with a chest tube is to ensure tube patency and observe for air leaks. This is essential to prevent complications such as pneumothorax and ensure the patient's lung function. While maintaining sterile technique during dressing changes, monitoring drainage, recording output, and observing for signs of infection and subcutaneous emphysema are also important, ensuring tube patency takes precedence as it directly impacts the patient's respiratory status and overall safety.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a technique that helps improve breathing efficiency in individuals with COPD by preventing airway collapse and allowing for better air exchange. Choice B is incorrect because breathing deeply and quickly can lead to hyperventilation and worsen symptoms in COPD patients. Choice C is incorrect because the incentive spirometer is a device used to encourage deep breathing and improve lung function, so it should not be avoided. Choice D is incorrect because physical activity is important for maintaining overall health and should be encouraged in a controlled and appropriate manner for individuals with COPD.

Correct Answer: A

Rationale: When managing a patient with a fever, the appropriate approach involves administering antipyretics to reduce the fever and monitoring the patient's vital signs to assess their response to treatment. Administering antipyretics helps to lower the body temperature and manage fever symptoms effectively. Monitoring vital signs is crucial to ensure the patient's condition is improving. Providing cold compresses, as mentioned in choice B, can help in managing fever symptoms, but it does not address the root cause of the fever. Encouraging the patient to rest, as stated in choice C, is beneficial for recovery, but increasing fluid intake is essential to prevent dehydration. Restricting fluid intake and providing bed rest, as in choice D, can lead to dehydration and hinder the body's ability to fight off the infection causing the fever. Therefore, the best course of action for a healthcare provider is to administer antipyretics while closely monitoring the patient's vital signs.

Correct Answer: A

Rationale: Hypoglycemia typically presents with sweating and trembling, while hyperglycemia is characterized by frequent urination and thirst. Therefore, the correct key differences between hypoglycemia and hyperglycemia are that hypoglycemia includes symptoms like sweating and trembling, while hyperglycemia involves symptoms such as frequent urination and thirst. Choices B, C, and D are incorrect because they do not accurately represent the characteristic symptoms of hypoglycemia and hyperglycemia, as stated in the question.
