community health nurse notes that six new cases of diabetes mellitus have been reported in the past 3 months. In the previous year, five cases were reported. The population of the community is 15,000 people. Which of the following is the prevalence proportion for the community?
11/15,000
6/15,000
11/11,000
6/11,000
The Correct Answer is A
Choice A reason: This statement is true and relevant. The prevalence proportion is the number of existing cases of a disease divided by the total population at risk. In this case, the existing cases of diabetes mellitus are 11 (6 new cases plus 5 old cases), and the total population at risk is 15,000. Therefore, the prevalence proportion is 11/15,000, which can be simplified to 0.00073 or 0.073%.
Choice B reason: This statement is false and misleading. The prevalence proportion is not calculated by using only the new cases of a disease, but by using the total number of existing cases. Using only the new cases would result in an underestimation of the prevalence proportion.
Choice C reason: This statement is false and misleading. The prevalence proportion is not calculated by using the difference between the total population and the existing cases of a disease, but by using the total population at risk. Using the difference would result in an overestimation of the prevalence proportion.
Choice D reason: This statement is false and misleading. The prevalence proportion is not calculated by using both the difference between the total population and the existing cases of a disease and the new cases of a disease, but by using the total number of existing cases and the total population at risk. Using both the difference and the new cases would result in an incorrect calculation of the prevalence proportion.

Correct Answer is C
Explanation
Choice A reason: Assembling an emergency disaster response team is not the first action to take when developing a disaster-preparedness plan. The nurse should first assess the community's needs and resources before forming a team.
Choice B reason: Evaluating the effectiveness of local disaster-preparedness drills is not the first action to take when developing a disaster-preparedness plan. The nurse should first identify the potential hazards and vulnerabilities of the community before conducting or reviewing any drills.
Choice C reason: Identifying the community's risks and capabilities is the first action to take when developing a disaster-preparedness plan. The nurse should perform a comprehensive assessment of the community's strengths, weaknesses, opportunities, and threats (SWOT) related to disaster management.
Choice D reason: Providing education about first aid and triage is not the first action to take when developing a disaster-preparedness plan. The nurse should first determine the learning needs and preferences of the community before designing and implementing any educational programs.
Correct Answer is B
Explanation
Choice A: The client’s insurance provides coverage for palliative care
This option is incorrect. While insurance coverage for palliative care is important, it is not a qualifying criterion for hospice care. Hospice care eligibility is primarily based on the patient’s medical condition and prognosis, not on insurance coverage.
Choice B: The client has declined additional life prolonging treatments
This option is correct. One of the key criteria for hospice care is that the patient must choose palliative care (comfort care) over curative treatments. This means the patient has decided to stop treatments aimed at prolonging life and instead focus on quality of life and symptom management.
Choice C: The client requires inpatient care due to lack of a caregiver
This option is incorrect. While the need for inpatient care can be a factor in the type of hospice services provided, it is not a criterion for qualifying for hospice care. Hospice care can be provided in various settings, including the patient’s home, regardless of caregiver availability.
Choice D: The client has documentation stating he has less than 12 months to live
This option is incorrect. The standard criterion for hospice care is a prognosis of six months or less to live if the disease follows its usual course. Documentation stating a life expectancy of less than 12 months does not meet the hospice eligibility requirement.
