According to Freeman and Heinrich, community health nursing is a developmental service. Which of the following best illustrates this statement?

Correct Answer: B

Rationale: The correct answer is B because health education and community organizing are essential components of community health nursing, aligning with the concept of developmental service. Health education promotes individual and community empowerment, while community organizing fosters partnerships and collaboration for sustainable health outcomes. Now, let's analyze why the other choices are incorrect: A: While personal and professional development is important for a community health nurse, it does not directly illustrate the developmental service aspect of community health nursing. C: Health promotion, prevention, and treatment of disease are important aspects of community health nursing, but they do not specifically highlight the developmental service nature. D: Providing nursing services in people's residences is a common practice in community health nursing, but it does not directly relate to the developmental service aspect emphasized by Freeman and Heinrich.

Correct Answer: B

Rationale: The correct answer is B: Ensure accessibility and quality of health. This is because the Department of Health's primary mission is to provide accessible and high-quality healthcare services to the population. This mission encompasses both ensuring that health services are within reach of all individuals and that the services provided are of the highest possible standard. Choices A, C, and D are incorrect because they do not fully capture the comprehensive mission of the Department of Health, which goes beyond just improving health status or setting a specific target year for health outcomes.

Correct Answer: B

Rationale: Step 1: Cyclical variation refers to a pattern that repeats at regular intervals. Step 2: The increase in Dengue fever cases at the end of the rainy season is a recurring pattern. Step 3: The rise in cases is linked to the environmental conditions during the rainy season. Step 4: This cyclic increase in cases is not a sudden outbreak (epidemic) or random (sporadic). Step 5: Secular occurrence refers to long-term trends, not short-term patterns like the end of a season. Summary: Choice B is correct because the pattern of Dengue fever cases increasing at the end of the rainy season aligns with cyclical variation, unlike the other options which do not accurately describe this specific pattern.

Correct Answer: A

Rationale: The correct answer is A: Establishing the epidemic. During this stage, comparing the present disease frequency with the usual frequency helps determine if there is a significant increase, indicating an epidemic. This step is crucial for recognizing and confirming the outbreak. Testing the hypothesis (B) comes after the epidemic is established. Formulation of the hypothesis (C) involves developing a theory based on observations, not comparing frequencies. Appraisal of facts (D) occurs after data collection, not during the initial comparison.

Correct Answer: B

Rationale: The correct answer is B (101 employees) because the Occupational Safety and Health Administration (OSHA) regulations require a business to have an occupational health nurse when the workforce reaches 101 employees. Employing an occupational health nurse at this threshold ensures that the company complies with OSHA standards for employee health and safety. Choices A, C, and D are incorrect because they do not align with the specific OSHA requirement of 101 employees for employing an occupational health nurse. Option A (21 employees) is too low, and options C (201 employees) and D (301 employees) exceed the required threshold. Therefore, only option B meets the OSHA regulation criteria for when a business must employ an occupational health nurse.

Correct Answer: D

Rationale: The correct answer is D because person-to-person propagated epidemics typically exhibit a gradual build-up of cases before becoming easily noticeable. This is due to the slow transmission of the disease from one individual to another. In contrast, choice A is incorrect because having more cases than expected is not a characteristic unique to person-to-person propagation. Choice B is incorrect as person-to-person transmission does not necessarily involve a vector. Choice C is incorrect because common vehicle spread refers to a different mode of disease transmission.

Correct Answer: B

Rationale: The correct graph to compare the frequency of leading causes of mortality is a bar graph (Choice B). A bar graph is ideal for comparing different categories of data, such as causes of mortality. The length of each bar represents the frequency of each cause, allowing for easy visual comparison. Line graphs (Choice A) are better for showing trends over time. Pie charts (Choice C) are suitable for showing parts of a whole, not for comparison. Scatter diagrams (Choice D) are used to show the relationship between two variables, not for comparing frequencies.

Correct Answer: A

Rationale: The primary purpose of conducting an epidemiologic investigation is to delineate the etiology of the epidemic. This involves studying the causes and risk factors contributing to the outbreak of the disease. Understanding the etiology helps in developing prevention and control strategies. Other choices are incorrect because encouraging cooperation and support of the community (B) and identifying groups at risk (C) are important outcomes but not the primary purpose of the investigation. Similarly, identifying geographical locations of disease cases (D) is essential for mapping the spread but not the main objective of determining the cause.

Correct Answer: B

Rationale: The correct answer is B: Should minimize, if not totally prevent, the spread of infection. The bag technique in home visits is crucial to prevent the spread of infections between different households. By ensuring that all equipment is properly sanitized and stored in the bag, the risk of contamination is minimized. This approach follows the principles of infection control and promotes patient safety. The other choices are incorrect because: A does not prioritize infection control, C is important but not the primary focus of the bag technique, and D undermines the importance of consistency in infection prevention.
