A nurse is assessing an outbreak of mumps among school-age children. Using the epidemiological triangle, the nurse should recognize that which of the following is the host?

The correct answer is Choice C because, "Clients will schedule bone density screenings." Postmenopausal women are at an increased risk for osteoporosis, and bone density screenings can help identify early signs of the disease, enabling early intervention to prevent complications.

Choice A is wrong because, "Clients will start hormone replacement therapy," is not the correct answer because hormone replacement therapy is not appropriate for all women and can have

negative side effects. It is not an appropriate outcome for an educational program.

Choice B is wrong because, "Clients will significantly decrease caloric intake," is not the correct answer because this outcome is not relevant to postmenopausal women specifically. Additionally, significant caloric restriction can lead to malnutrition and other negative health outcomes.

Choice D is wrong because, "Clients will arrange for mammograms every 3 years," is not the correct answer because while mammograms are an important screening tool for breast cancer, they are not specific to postmenopausal women and should be recommended to all women starting at age 40. Bone density screenings are a more appropriate outcome for a program specifically targeting postmenopausal women.

The correct answer is Choice B because it "Examines the prevalence of childhood obesity in the community." The nurse should gather data on the extent of the problem in the community before planning interventions. Promoting the placement of healthy food choices in the community (Choice A is wrong because), providing nutritional education to children and their families (Choice C is wrong because), and establishing goals for the community to decrease childhood obesity (Choice D is wrong because) are all important steps in addressing the issue, but should be based on an understanding of the extent and nature of the problem.

Choice A is wrong because: Promoting the placement of healthy food choices in the community is an important step in addressing childhood obesity, but should be based on an understanding of the extent and nature of the problem.

Choice C is wrong because Providing nutritional education to children and their families is an important step in addressing childhood obesity, but should be based on an understanding of the extent and nature of the problem.

Choice D is wrong because Establishing goals for the community to decrease childhood obesity is an important step in addressing childhood obesity, but should be based on an understanding of the extent and nature of the problem.
