Q

The community nurse provides care for a client who has experienced blindness as a result of diabetes mellitus. In the natural history of diabetes mellitus, the nurse identifies the onset of blindness as reflective of which stage?

  1. susceptibility
  2. Exposure
  3. Clinical
  4. Early pathogenesis
A

3 (clinical) is correct –> In stage 4, also known as the culmination stage, the disease or health condition causes sufficient anatomic or functional changes to produce recognizable signs and symptoms
rationale:
1- susceptibility is stage 1 where the disease is not present and individuals have not been exposed
2- Stage 2 occurs when individuals have been exposed to a disease but are asymptomatic
4- in stage 3, signs and symptoms actually begin to develop

    * primary prevention is an intervention that is implemented before there is evidence of disease and injury. Family planning/pregnancy prevention is a form of primary prevention

rationale:
1. this example represents tertiary prevention (intervention is implemented after a disease or injury)
3. this is secondary prevention (after a disease has begun but before it is symptomatic)
4. secondary prevention

51
Q

The nurse identifies which characteristic BEST serves as an indicator of a community social index?

  1. suicide rate
  2. ratio of firefighters to residents
  3. location of mental health services
  4. prematurity birth rates
A
  1. ratio of firefighters to residents
    * a community social index uses numerical measures that describe the well-being of communities. Indicators are made up of one or several components combined into an index. They are used to describe and evaluate community well-being in terms of social, economic, and psychological welfare. The number of protective services to the number of residents is an example of social indexes

rationale:
1. this serves as a measure of the community health status
3. the number of mental health services, versus the locations, would serve as a measure of the community’s health status
4. this serves as a measure of the community health status

52
Q
