Public Health Nursing Practice Exam

Which factor significantly contributes to a host's susceptibility to disease?

1. Diet and nutrition

2. Geographic location

3. Socioeconomic status

4. Access to healthcare

The correct answer is: Diet and nutrition

Diet and nutrition play a significant role in a host's susceptibility to disease as they directly influence the immune system's strength and overall health. Proper nutrition provides essential vitamins, minerals, and other nutrients that are crucial for maintaining optimal bodily functions, including the immune response. A well-balanced diet can help mitigate the risk of infections and chronic diseases by fostering a stronger immune system, enhancing the body's ability to fight off pathogens, and promoting overall health. While geographic location, socioeconomic status, and access to healthcare are also important factors that can impact a person's health and likelihood of disease, they do so in ways that are often indirect. Geographic location can affect environmental exposures and availability of resources, socioeconomic status determines access to healthy foods and resources, and access to healthcare influences the ability to receive preventive care and treatment. However, without adequate nutrition, even individuals with the best healthcare options may still struggle to maintain good health and reduce their susceptibility to disease.
