Correct Answer: D

Rationale: The correct answer is D, physical therapy. Tertiary prevention focuses on rehabilitation and treatment to prevent complications from a disease or injury. Physical therapy falls under this category as it helps individuals recover and improve functionality after an illness or injury. Choices A, B, and C are not examples of tertiary prevention. 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: A

Rationale: A rapid weight gain of 2 pounds or more in a 48-hour period may indicate fluid retention and worsening heart failure, requiring prompt medical evaluation and intervention. This finding is crucial in managing chronic congestive heart failure as it signifies a potential exacerbation of the condition. Choices B, C, and D are less concerning in this context. Urinating 4 to 5 times a day is within the normal range for most individuals and may not be directly related to heart failure. A significant decrease in appetite may be due to various factors and might not be an immediate cause for concern in heart failure patients. The appearance of non-pitting ankle edema, although related to heart failure, is a more chronic and less urgent symptom when compared to a rapid weight gain, which requires immediate attention.

Correct Answer: B

Rationale: The correct answer is B: Anemia. Zidovudine (Retrovir) can cause bone marrow suppression, leading to anemia. Monitoring for signs of anemia, such as fatigue, pallor, and shortness of breath, is crucial. Choice A, Hyperglycemia, is not a common adverse effect of zidovudine. Choice C, Hypertension, is not directly associated with zidovudine use. Choice D, Hypercalcemia, is also not a typical adverse effect of zidovudine.

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. Choice C is incorrect as identification and assessment are steps that may be involved but not the main focus. Choice D is incorrect as it refers to the illness end rather than the preventive end of the wellness-illness continuum.

Correct Answer: A

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.
