A community health nurse is calculating the top three causes of death in a county. Which of the following mortality measures should the nurse use to obtain this data?

Choice A Reason:
The portal of entry refers to the site through which pathogens enter the body. While handwashing can indirectly affect the portal of entry by reducing the number of pathogens on the hands, it primarily targets the mode of transmission. The portal of entry includes areas such as the respiratory tract, gastrointestinal tract, and breaks in the skin.

Choice B Reason:
The susceptible host is an individual who is at risk of infection due to factors such as age, underlying health conditions, or weakened immune systems. Handwashing does not directly alter the susceptibility of the host but rather reduces the likelihood of the host coming into contact with pathogens.

Choice C Reason:
The portal of exit is the site from which pathogens leave the host to infect another individual. Common portals of exit include the respiratory tract, gastrointestinal tract, and open wounds. Handwashing does not directly impact the portal of exit but helps prevent the spread of pathogens from one person to another.

Choice D Reason:
Mode of transmission refers to the way pathogens are transferred from one host to another. Handwashing is a critical intervention that targets this link in the chain of transmission by removing pathogens from the hands, thereby preventing their spread through direct contact or contact with contaminated surfaces. This is why proper handwashing technique is emphasized in infection control practices.

Choice A Reason:
Posting the analyzed findings on the health department section of the city's website is important for transparency and public awareness. It allows the community to access the information and understand the health issues identified. However, this action alone does not directly address the health issues identified in the assessment. It is more of a communication strategy rather than an intervention.

Choice B Reason:
Educating members of a vulnerable population about available public health services is a crucial step in ensuring that these populations can access the services they need. This action helps in bridging the gap between the health department and the community. However, it is a part of the implementation phase rather than the planning phase. The primary goal of the assessment is to identify issues and plan interventions.

Choice C Reason:
Conducting focus groups with local residents to discuss their usage of public health services is a valuable method for gathering qualitative data and understanding community needs and behaviors. This can provide deeper insights into the issues identified in the assessment. However, like choice B, this is more of a data collection method rather than a direct action plan to address the identified health issues.

Choice D Reason:
Preparing a plan to address a health issue in a specific area of the city is the most direct and actionable step that aligns with the core function of assessment. The purpose of conducting a community health assessment is to identify health issues and develop strategies to address them. This choice involves creating a targeted intervention plan based on the findings, which is the ultimate goal of the assessment process.
