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?

Choice A reason: The best first step for a community health nurse is to connect directly with the people who are most affected by the issue. Meeting with community members allows the nurse to assess their concerns, gather information on how the playground is currently used, and explore what resources and willingness the residents have to participate in solutions. This approach promotes community engagement, empowerment, and ownership of the issue, which are critical to ensuring that any interventions are both sustainable and culturally appropriate. Without this initial dialogue, actions taken may not address the true barriers or may fail to gain community support.

Choice B reason: Partnering with city officials and community members to improve the playground condition is not the first action that the nurse should take. This is a tertiary intervention that can help to restore the playground to its optimal state, but it does not address the immediate issue of the garbage accumulation.

Choice C reason: Working with local businesses to sponsor more trash receptacles in the playground is not the first action that the nurse should take. This is a secondary intervention that can help to prevent the recurrence of the problem, but it does not address the immediate issue of the garbage accumulation.

Choice D reason: Engaging families to monitor trash buildup in the playground focuses on surveillance and maintenance, but this step requires prior discussion and buy-in from the community. Asking families to monitor the site without first understanding their concerns, availability, and willingness could lead to resistance or lack of participation. This is a useful strategy after community dialogue has occurred but not as the first step.

Choice A reason: Scheduling bone density screening is an appropriate outcome for the program, as it helps to detect and prevent osteoporosis, a common condition among postmenopausal women. Bone density screening is recommended for women aged 65 years and older, or younger women with risk factors.

Choice B reason: Arranging for mammograms every 3 years is not an appropriate outcome for the program, as it does not follow the current guidelines for breast cancer screening. The American Cancer Society recommends that women aged 45 to 54 years should have mammograms every year, and women aged 55 years and older should have mammograms every 2 years, or continue yearly screening if they prefer.

Choice C reason: Starting hormone replacement therapy is not an appropriate outcome for the program, as it is not a universal recommendation for postmenopausal women. Hormone replacement therapy may have benefits and risks depending on the individual's health history, symptoms, and preferences. It should be discussed with a health care provider before starting.

Choice D reason: Significantly decreasing caloric intake is not an appropriate outcome for the program, as it may lead to nutritional deficiencies and other health problems. Postmenopausal women should maintain a balanced diet that meets their nutritional needs and supports their weight management. A moderate reduction in caloric intake may be advised for overweight or obese women, but not a drastic one.
