Correct Answer: A

Rationale: The correct answer is A. A patient with known COPD and difficulty breathing after physical exertion like climbing stairs requires immediate assessment by the nurse. This could indicate a potential exacerbation of COPD, which needs prompt intervention to prevent respiratory distress. Choices B, C, and D describe important patient situations that also require attention, but the urgency is higher with a COPD patient experiencing difficulty breathing.

Correct Answer: C

Rationale: The correct answer is C. Poison ivy can be contracted through smoke from burning plants, which can carry the urushiol oil that causes the rash. Playing near burning leaves would be the highest risk for exposure in this scenario. Choices A, B, and D do not involve direct contact with burning plants or leaves, making them lower-risk activities for exposure to poison ivy.

Correct Answer: A

Rationale: The correct answer is A: Cigarette smoking. Cigarette smoking is a significant risk factor for low birth weight. Smoking during pregnancy reduces the amount of oxygen available to the baby, leading to LBW. Choice B, African American ethnicity, while it may be a risk factor, is not as directly linked to LBW as cigarette smoking. Choice C, poor nutritional status, can contribute to LBW but is not as significant as cigarette smoking in this case. Choice D, limited maternal education, is an important social determinant of health but is not as directly related to LBW as cigarette smoking.

Correct Answer: B

Rationale: The Healthy People initiative is a national agenda that focuses on reducing health disparities and improving the health of all Americans. Choice A is incorrect because the initiative is more about improving health outcomes and access rather than providing healthcare to all citizens. Choice C is not the main goal of the initiative, which is more about public health goals than medical research. Choice D is also not the primary aim of the Healthy People initiative, as it is more focused on setting objectives to improve public health.

Correct Answer: A

Rationale: To effectively plan and implement an occupational health program, the nurse needs comprehensive data, including disease trends, birth and death rates, and social environmental conditions. This holistic approach ensures that the program addresses a wide range of health aspects impacting the target population. Option A is the correct choice as it considers multiple factors influencing occupational health. Choices B, C, and D are each individually important but do not provide the breadth of information required to establish priorities in a comprehensive occupational health program.
