A nurse in a public clinic is planning a health fair for clients in the community who are at risk for developing type 2 diabetes mellitus. Which of the following activities should the nurse include for secondary prevention?
A Demonstrating a 15-minute exercise routine
B Screening for blood sugar levels
C Providing a cooking lesson using sugar alternatives
D Educating about stress management strategies
The Correct Answer and Explanation is:
The correct answer is B: Screening for blood sugar levels.
Explanation:
In public health, prevention strategies are typically divided into three categories: primary, secondary, and tertiary prevention. Each level of prevention targets a different phase of disease progression, aiming to reduce the impact of illness on individuals and the population.
Primary prevention focuses on preventing a disease before it occurs by promoting health and reducing risk factors. This could involve activities such as health education, immunizations, and encouraging lifestyle changes (e.g., promoting regular physical activity or healthy eating habits). Examples from this scenario include demonstrating an exercise routine or providing a cooking lesson using sugar alternatives, which are aimed at reducing the risk of developing type 2 diabetes mellitus. These are primary prevention strategies because they aim to prevent the onset of the disease.
Secondary prevention involves the early detection of a disease or condition, typically through screening and diagnostic tests, in order to intervene early and reduce complications. It is aimed at individuals who may already be at risk or have early signs of the disease but may not yet show significant symptoms. Screening for blood sugar levels falls into this category. By identifying individuals with elevated blood sugar or early stages of diabetes (such as prediabetes), the nurse can facilitate early treatment or interventions to manage the disease and prevent further complications. Blood sugar screening can detect individuals with high glucose levels who may not yet be diagnosed with diabetes, making it a key component of secondary prevention.
Tertiary prevention focuses on managing and mitigating the impact of an established disease to reduce complications, improve quality of life, and prevent further deterioration. For example, teaching stress management strategies for those with diabetes could help in controlling blood sugar levels, which may reduce the risk of complications. However, this is considered tertiary prevention, not secondary, because it targets disease management rather than early detection.
Thus, B: Screening for blood sugar levels is the correct answer because it directly aligns with the goal of secondary prevention, which is to detect early disease in at-risk individuals to prevent the progression of type 2 diabetes.
