Correct Answer: A

Rationale: The correct answer is A: Apply a sterile dressing. Firstly, cover the wound with a sterile occlusive dressing to prevent air from entering the pleural space, reducing the risk of tension pneumothorax. This also helps to prevent infection and further complications. Administering morphine (B) or nitroglycerin (D) is not the priority in this situation as managing the chest wound is crucial. Applying an airtight dressing (C) may lead to tension pneumothorax if not done properly. Therefore, the immediate action should be to apply a sterile dressing to stabilize the wound and prevent further complications.

Correct Answer: A

Rationale: The correct answer is A: Immobilize the client. This is crucial to prevent further damage to the spinal cord. Moving a client with a suspected spinal cord injury can worsen the injury and lead to permanent damage. Immobilizing the client helps maintain spinal alignment and reduces the risk of paralysis. Providing pain relief (B) and loosening clothing (D) are important but secondary actions. Applying pressure to the chest (C) is not recommended for a suspected spinal cord injury as it can also exacerbate the injury.

Correct Answer: B

Rationale: The correct answer is B because reducing alcohol consumption and limiting sodium intake are both crucial lifestyle modifications for managing hypertension. Alcohol can raise blood pressure, while excess sodium can contribute to hypertension. By prioritizing these changes, the patient can better control their blood pressure. Choice A is incorrect because increasing sodium intake can worsen hypertension due to fluid retention. Choice C is incorrect as decreasing physical activity can lead to weight gain and worsen hypertension. Choice D is incorrect as processed foods are often high in sodium and unhealthy fats, which can negatively impact blood pressure.

Correct Answer: C

Rationale: The correct answer is C because using the inhaler every time the patient feels short of breath, even without a flare-up, is not the recommended practice for managing COPD. Inhalers should be used as prescribed by the healthcare provider or only during exacerbations. Here's the rationale: 1. Using the inhaler excessively can lead to overuse of medication and potential side effects. 2. It is important for patients to differentiate between regular management and acute exacerbations. 3. Monitoring oxygen levels (choice D) is essential for COPD management. 4. Quitting smoking (choice A) and deep breathing exercises (choice B) are positive self-management strategies for COPD.

Correct Answer: A

Rationale: The correct answer is A: "Smoking increases the risk of complications during surgery." Smoking constricts blood vessels, reduces oxygen levels, and impairs the body's ability to heal. This can lead to increased risks of infections, delayed wound healing, and other complications during and after surgery. Choice B is vague and does not address the specific risks associated with smoking. Choice C is too general and does not emphasize the immediate risks related to surgery. Choice D implies a benefit after surgery rather than focusing on the risks associated with smoking before surgery.
