The public health nurse understands that which of the following is an example of a vector borne disease?

A. Putting students on a diet if they weigh greater than 20% of their ideal weight: This is a tertiary prevention strategy, as it focuses on managing obesity after it has been diagnosed rather than early detection.

B. Weighing students to identify those who are overweight: Secondary prevention focuses on early detection and intervention to prevent disease progression. Weighing students allows for early identification of obesity and timely interventions.

C. Giving a presentation on the importance of exercise and physical fitness: This is primary prevention, which aims to prevent obesity before it occurs by promoting healthy habits.

D. Designing a game in which students select healthy food choices: This is also primary prevention, as it promotes healthy behaviors rather than identifying or managing existing obesity.

A. Appreciate that the family has made the decision that it feels is best and take no further action if it is clear the family has made an informed choice: Respecting autonomy is a key ethical principle in nursing. If the family has made an informed decision without coercion, the nurse should respect their choice. Beneficence and nonmaleficence do not override autonomy in this case.

B. Try to convince the agency to give the care for free, even if it means economic stress for the agency, because the medical need is obvious: While advocacy is important, it is unethical to place financial strain on an agency without proper policy in place. This option disregards justice (fair distribution of resources).

C. Stress that each individual in society has a right to healthcare and the family will have to create some way to raise funds for the needed treatment: While healthcare access is a concern, pressuring the family to raise funds imposes unrealistic expectations and does not respect their right to decline care.

D. Talk to the media to see whether a campaign to raise funds for the family can be created: Disclosing a family's personal health information without consent violates confidentiality and privacy rights under ethical and legal guidelines.
