Rationale: The correct answer is A: Stop smoking. Smoking causes vasoconstriction, worsening the symptoms of Raynaud's phenomenon. Quitting smoking is crucial in managing this condition effectively. Choices B, C, and D are not as directly related to the pathophysiology of Raynaud's phenomenon. While keeping feet dry and reducing stress can be beneficial for overall health, they are not as directly linked to managing Raynaud's phenomenon as smoking cessation.

Rationale: The correct answer is D, physical therapy. Tertiary prevention focuses on rehabilitation and treatment to prevent complications from a disease or injury.

Health education (choice A) is more aligned with primary prevention by promoting healthy behaviors to prevent disease onset. Regular exercise (choice B) can be categorized under both primary and secondary prevention as it aims to prevent disease development and detect conditions early. Screening tests (choice C) are part of secondary prevention as they aim to detect diseases at an early stage for prompt treatment.

Correct Answer: B

Rationale: Community health nursing primarily focuses on preventive measures and promoting overall health within a community. Choice A is incorrect as treatment is not the main emphasis.

Choices A, B, and D are incorrect as they do not directly contribute to the development of decubitus ulcers in this context.
