An occupational health nurse works at a manufacturing plant where there is potential exposure to inhaled dust. Which action, if recommended by the nurse, will be most helpful in reducing the incidence of lung disease?

Correct Answer: C

Rationale: Prevention of lung disease requires the use of appropriate protective equipment such as masks to reduce exposure to inhaled dust, which is a significant risk factor for lung disease. Teaching about symptoms of lung disease, treating workers with pulmonary fibrosis, and monitoring for coughing and wheezing are important actions for early recognition and treatment of lung disease. However, the most effective strategy to prevent lung damage in this scenario is to require the use of protective equipment to minimize exposure to harmful substances.

Correct Answer: A

Rationale: The most critical information for the nurse to provide to a patient with a significant smoking history is options for smoking cessation. Smoking is the primary cause of lung cancer, making smoking cessation essential in reducing the risk of developing the disease. Annual sputum cytology testing is not a standard screening test for lung cancer; instead, CT scanning is being explored for this purpose. Erlotinib therapy is used in lung cancer treatment but not for preventing tumor risk in individuals without cancer. CT screening for lung cancer is still under investigation and is not primarily aimed at prevention but rather early detection in high-risk individuals.

Correct Answer: A

Rationale: The correct answer is 'nosocomial.' A nosocomial infection is defined as one that is not present upon admission to a healthcare facility but instead occurs during the patient's stay. In this case, since Mary was diagnosed with a skin infection after being admitted to the nursing home, it is considered a nosocomial infection. Nosocomial infections are a significant concern in healthcare settings, and infection control measures are in place to prevent their spread. Choices B, C, and D are incorrect. 'Systemic' refers to a condition affecting the entire body, not specific to a healthcare setting. 'Resident flora' and 'resident aura' are not commonly used terms in healthcare and do not relate to infections acquired in healthcare facilities.

Correct Answer: A

Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.
