A nurse is investigating a mumps outbreak among school-age children.
Using the epidemiological triangle, the nurse should identify which of the following as the host?
The virus.
The vaccine.
The school.
The children.
The Correct Answer is D
Choice A rationale
In the epidemiological triangle, the virus is considered the agent, not the host.
Choice B rationale
The vaccine is a form of intervention to prevent the disease, not the host.
Choice C rationale
The school could be considered the environment in which the host (the children) and the agent (the virus) interact, but it is not the host itself.
Choice D rationale
This is the correct answer. In the context of a mumps outbreak among school-age children, the children are the hosts. They are the ones who can become infected with the mumps virus.

Correct Answer is B
Explanation
The correct answer is Choice B
Choice A rationale: Referring the client to a diabetes mellitus support group is beneficial but not the initial action. The nurse should first gather information about the client's preferences and needs to tailor the intervention effectively.
Choice B rationale: Identifying the client's dietary preferences is essential for developing a personalized nutritional plan. Understanding the client's likes, dislikes, and cultural factors ensures that dietary recommendations are realistic and sustainable, promoting better adherence and management of diabetes.
Choice C rationale: Developing a nutritional program is a crucial step but should follow the assessment of the client's dietary preferences. A personalized approach based on the client's individual needs and lifestyle is necessary for effective diabetes management.
Choice D rationale: Teaching the client about appropriate food choices is important but should be done after understanding the client's dietary preferences. This ensures that the education is relevant and practical, helping the client make informed decisions about their diet
Correct Answer is B
Explanation
The correct answer is Choice B
Choice A rationale: Turning the patient every 4 hours may prevent pressure ulcers, but it can cause discomfort for a near-death patient. Less frequent repositioning might be more suitable for maintaining comfort during the end-of-life stage.
Choice B rationale: Elevating the head of the patient's bed can help ease breathing difficulties by reducing the pressure on the diaphragm and enhancing lung expansion. This position promotes comfort and reduces the work of breathing, which is beneficial for near-death patients.
Choice C rationale: Offering the patient ice chips can provide temporary relief from dry mouth, but it may not be the most effective measure for ensuring comfort. Adequate hydration and regular oral care are generally more beneficial for maintaining patient comfort.
Choice D rationale: Providing oral care every 6 hours might not be frequent enough to ensure comfort. More frequent oral care, such as every 2 hours, helps maintain moisture in the mouth, reduces discomfort, and prevents infections, enhancing the patient's overall comfort
