A nurse is caring for a 9-year-old child who mimics shooting a gun with their hand whenever someone enters the room or tries to interact with them.

 This is an example of which manifestation of post-traumatic stress disorder? 

Choice A rationale
Quality education does not typically include coverage for medical expenses. Education and healthcare are generally considered separate entities, with different funding and administration.
Choice B rationale
Individuals who attain a quality education are indeed more likely to secure a job that pays a living wage. Education often provides the skills and knowledge necessary for higher-paying

jobs, which can lead to improved health outcomes through increased access to healthcare, healthier lifestyles, and better living conditions.
Choice C rationale
While technology and virtual healthcare services are increasingly being integrated into various aspects of society, quality education does not inherently provide increased access to virtual visits with primary care physicians.
Choice D rationale
The requirement to purchase healthy lunches at school is not a characteristic of quality education. While nutrition is important for overall health and academic performance, it is not a defining factor of the quality of education.

Choice A rationale
Clean drinking water is indeed crucial for preventing many diseases, especially those transmitted through the fecal-oral route or waterborne diseases such as cholera, typhoid, and hepatitis A1. However, it is not specifically targeted at diseases that are transmitted directly from person to person. Directly transmitted diseases are often spread through direct contact, such as person-to-person contact or droplet spread. Therefore, while clean drinking water is an essential aspect of public health, it is not the most effective method for preventing diseases that are transmitted directly.
Choice B rationale
Pest control is an important measure for preventing diseases transmitted by vectors, such as mosquitoes, ticks, and fleas. Diseases like malaria, dengue, Lyme disease, and plague are examples of vector-borne diseases. However, these diseases are not considered directly transmitted diseases. Direct transmission occurs when an infectious agent is transferred from a reservoir to a susceptible host by direct contact or droplet spread. Therefore, pest control, while important, is not the primary prevention method for diseases that are transmitted directly.
Choice C rationale

Isolation is one of the most effective methods for preventing the spread of directly transmitted diseases. When a person is isolated, they are separated from others to prevent the spread of communicable diseases. Isolation is used in healthcare settings to prevent the spread of infectious diseases that can be transmitted directly from person to person, such as tuberculosis, influenza, and COVID-191. Therefore, isolation is a key prevention method for diseases that are transmitted directly.
Choice D rationale
Proper sanitation, like clean drinking water, is crucial for preventing many diseases, particularly those transmitted through the fecal-oral route. Proper sanitation involves safely managing human waste and maintaining hygienic conditions through services such as garbage collection and wastewater disposal. While it is an essential aspect of public health, proper sanitation is not the most effective method for preventing diseases that are transmitted directly from person to person.
