Which factor would cause a geographic area to be called a frontier area?

Correct Answer: A

Rationale: The correct answer is A because a frontier area is typically characterized by low population density, making it sparsely populated. A population growth of less than six persons per square mile aligns with this definition. On the other hand, choices B, C, and D are incorrect as they do not reflect the key characteristic of low population density associated with frontier areas. Choice B specifies a slightly higher population density threshold, while choice C refers to urbanization, which is not a defining feature of frontier areas. Choice D, rapid population growth, is contrary to the typical slow population growth associated with frontier regions.

Correct Answer: D

Rationale: The correct answer is D because persistent poverty refers to a prolonged period of poverty. A county would be defined as having persistent poverty if its population has been in poverty for over 30 years. This timeframe demonstrates a long-standing issue of poverty that has persisted for a significant duration. Choices A, B, and C do not meet the threshold for persistent poverty as they represent shorter durations. Choice A (10 years) and B (20 years) may indicate some level of sustained poverty but do not fully capture the concept of persistent poverty. Choice C (25 years) is closer but still falls short of the extended timeframe required to be considered persistent poverty. Thus, the correct answer is D as it aligns with the definition of persistent poverty as a prolonged period of poverty lasting over 30 years.

Correct Answer: A

Rationale: The correct answer is A: Obesity and sedentary lifestyle. In rural areas of the South, access to healthy food options and recreational facilities may be limited, leading to higher rates of obesity and sedentary lifestyles. Furthermore, agricultural work in rural areas can be physically demanding, but it may not provide adequate exercise to combat sedentary behaviors. Choice B (Homicide and motor vehicle accidents) is less prevalent in rural areas due to lower population density and less traffic congestion. Choice C (Mental health issues and suicide) may be influenced by various factors, not specifically tied to rural areas. Choice D (Increased smoking and alcohol use) is not necessarily more prevalent in rural areas compared to urban areas.

Correct Answer: D

Rationale: The correct answer is D: Migrant and seasonal farmworkers (MSFW). 1. They are a vulnerable population due to limited access to healthcare. 2. They face occupational hazards and environmental exposures. 3. They often lack health insurance and have language barriers. 4. By focusing on this group, the nurse can address high-risk factors, preventive care, and health education. Summary: A: Elderly women may need care, but MSFW have higher risk factors. B: Disabled adults require care, but MSFW face unique challenges. C: Hispanic children are important, but MSFW may have immediate health risks.

Correct Answer: C

Rationale: The correct answer is C: Agricultural machinery. Agricultural machinery is the most frequent cause of farm fatalities and injuries due to the high-risk nature of operating heavy equipment on farms. Machinery accidents often result from improper use, maintenance, or lack of safety precautions. Food processing (A) and highway construction (B) are not directly related to farm fatalities. Transportation (D) can contribute to farm accidents but is not as frequent as agricultural machinery incidents on farms.
