Rationale: Secondary level health care facilities are equipped to perform minor surgeries and simple laboratory examinations. Intermediate level care (choice B) refers to a level of care between primary and secondary care, focusing on more complex procedures than minor surgeries. Tertiary level care (choice C) is specialized care that includes services like cardiac surgery and neurosurgery. Primary health care (choice D) is the first point of contact for individuals and is not typically equipped for minor surgeries or complex laboratory tests.

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.

Correct Answer: C

Rationale: In this scenario, requesting mayors to create a task force is the most effective strategy to improve environmental health conditions in the community. Engaging with local government officials ensures the allocation of resources, coordination of efforts, and the implementation of sustainable solutions. While meeting with youth officials, parents' group leaders, religious and educational leaders are important, involving mayors in creating a task force will lead to broader community involvement and support. Informing local announcers about the project, although helpful for awareness, is not as impactful as engaging with local authorities for tangible change.

Correct Answer: B

Rationale: Retinopathy of prematurity is the most common complication in premature infants exposed to high concentrations of oxygen. This condition leads to abnormal blood vessel growth in the retina, which can potentially result in blindness if not managed promptly. Intraventricular hemorrhage, though a significant concern in premature infants, is not directly related to oxygen therapy. Bronchopulmonary dysplasia is primarily associated with mechanical ventilation and oxygen exposure over time, not specifically with oxygen concentration monitoring. Necrotizing enterocolitis is more linked to gastrointestinal issues and is not the most common complication of oxygen therapy in premature newborns.

Correct Answer: B

Rationale: The correct answer is B. Occupational health nursing involves all aspects mentioned in the statements: prevention, recognition, treatment of injury and illness, application of nursing principles in conserving workers' health, and the requirement of special skills in health, education, and counseling. Choice A focuses on prevention, recognition, and treatment but does not encompass all aspects of occupational health nursing. Choice C only mentions the application of nursing principles without including prevention and treatment. Choice D specifically highlights the need for special skills but does not cover all the aspects of occupational health nursing.
