The correct answer is Choice D because, "Test a client who has a family history for diabetes mellitus." Secondary prevention refers to early detection and intervention to prevent the progression of disease. Testing individuals who have a family history of diabetes mellitus is an example of secondary prevention as it allows for early detection and intervention to prevent or delay the onset of diabetes.

Choice A is wrong because, "Educate a client who has hypertension about exercises to reduce blood pressure," is not the correct answer as it is an example of primary prevention, which focuses on preventing the development of disease or injury in individuals who are at risk. Hypertension is a risk factor for cardiovascular disease, and educating individuals about lifestyle modifications, such as exercise, can prevent the development of hypertension and other comorbidities.

Choice B is wrong because, "Teach a group of school-age children about hand hygiene," is not the correct answer as it is an example of primary prevention, which aims to prevent the occurrence of disease or injury in populations that are at risk.
