Correct Answer: A

Rationale: The primary goal of an occupational health program is to provide curative care to workers/employees. This includes preventing and treating work-related illnesses and injuries, promoting workplace safety, and ensuring the well-being of employees in their work environment. Choice B, birth and death rates, is not directly related to the primary goal of an occupational health program. Choice C, disease trends, may be a focus of public health programs but is not the primary goal of an occupational health program. Choice D, social environmental conditions, while important for overall health, is not the primary goal of an occupational health program which is more focused on the health and safety of workers in their work settings.

Correct Answer: C

Rationale: A serum bilirubin level of 12 mg/dL in a newborn is concerning and can indicate a significant risk of hyperbilirubinemia, which requires immediate medical intervention to prevent complications like kernicterus. Jaundice at 26 hours (Choice A) is a symptom, not a laboratory result, and needs monitoring but not an immediate report. Hematocrit of 55% (Choice B) may be elevated but is not indicative of hyperbilirubinemia. A positive Coombs test (Choice D) indicates the presence of antibodies on the newborn's red blood cells but does not directly correlate with the risk of hyperbilirubinemia.

Correct Answer: B

Rationale: The client's inability to effectively clear the airway due to pain and sputum production hinders the cough mechanism, making 'Ineffective airway clearance' the most appropriate nursing diagnosis. Although impaired gas exchange may occur due to the pneumonia, the immediate issue is the inability to clear the airway. 'Ineffective breathing pattern' does not address the specific issue of airway clearance. 'Anxiety' is not the priority when the focus should be on the physical complications of pneumonia.

Correct Answer: B

Rationale: The availability of healthcare services is a critical factor in determining community health. While the number of hospitals may contribute to healthcare accessibility, it is the overall availability of healthcare services that encompasses various factors including hospitals, clinics, healthcare providers, and resources. Socioeconomic status and population density are important determinants of health outcomes, but the direct availability of healthcare services plays a more immediate and direct role in promoting community health.

Correct Answer: B

Rationale: Community health nurses are primarily responsible for populations. While they do provide care and support to individuals and families within the community, their focus is on the health and well-being of entire populations. Choice A is incorrect as the primary responsibility is broader than just individuals. Choice C is incorrect as families are part of the population but not the sole focus. Choice D, 'class E citizens', is too specific and not a standard term in public health, making it an incorrect choice.
