ATI NURS 340 Leadership and Public Health Exam Questions
Extract:
Question 1 of 5
A nurse is examining the agent, host and environmental factors which can lead to disease. Which of the following models would the nurse most likely use?
Correct Answer: A
Rationale: The correct answer is A: Epidemiologic triangle. This model is used to understand the interplay between the agent (pathogen causing disease), host (person or organism affected), and environment (physical, social, and economic factors) in the development of disease. It helps identify risk factors and develop strategies for disease prevention and control.
Choice B, health promotion, focuses on promoting health behaviors rather than analyzing disease causation.
Choice C, natural history of disease, refers to the progression of a disease in an individual rather than the factors leading to disease in a population.
Choice D, levels of prevention, categorizes prevention efforts rather than analyzing the factors contributing to disease development.
Question 2 of 5
The nurse learns that a family has declined an elective medical intervention for a health care problem because paying for the care would drastically reduce the family's resources and ability to meet the needs of other family members. Ethically, which of the following actions should be taken by the nurse?
Correct Answer: A
Rationale: The correct answer is 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. This option respects the autonomy and decision-making ability of the family. The nurse should acknowledge the family's autonomy and respect their decision-making process. Pressuring the family or trying to convince them to change their decision would not be ethically appropriate as it undermines their autonomy. Options B, C, and D involve imposing the nurse's own beliefs or values on the family, which is not respectful or ethical. The nurse should support the family in making informed decisions that align with their values and beliefs.
Question 3 of 5
The public health nurse understands that endoparasites are which of the following? Select all that apply.
Correct Answer: B,D,E
Rationale: The correct answer is B, D, and E. Protozoal, roundworms, and tapeworms are all types of endoparasites that live inside the host's body. Protozoal parasites are single-celled organisms, roundworms are nematodes, and tapeworms are flatworms. Ticks (
A), mites (
C), and other external parasites live outside the host's body, making them incorrect choices in this context. Endoparasites can cause various infections and diseases in humans and animals, highlighting the importance of understanding their characteristics for effective public health interventions.
Question 4 of 5
The newly hired public health nurse understands that which of the following best describes the purpose of local health departments making unannounced inspections of local restaurants?
Correct Answer: D
Rationale: The correct answer is D:
To ensure compliance with food safety regulations. Unannounced inspections are conducted to verify that restaurants are following food safety guidelines and regulations to prevent foodborne illnesses. This helps protect public health by ensuring that proper food handling, storage, and preparation practices are being followed.
Choice A is not specific enough and does not address the main purpose of the inspections.
Choice B is related but does not focus on the specific aspect of food safety.
Choice C is not the primary purpose of these inspections.
Question 5 of 5
During an outbreak of measles, nurses are giving measles vaccinations to susceptible persons. Which of the following best describes the type of immunity that will follow the administration of these injections?
Correct Answer: D
Rationale: The correct answer is D: Active immunity. Administering measles vaccinations triggers the body's immune response to produce antibodies against the measles virus, providing long-lasting protection. This is an example of active immunity, where the immune system actively responds to an antigen to create memory cells for future protection.
A: Herd immunity refers to the indirect protection of unvaccinated individuals when a sufficient proportion of a population is immune.
B: Natural immunity is immunity acquired through natural exposure to a pathogen.
C: Acquired immunity is a general term for immunity obtained through vaccination or previous infection.
In summary, the administration of measles vaccinations results in active immunity by stimulating the immune system to produce specific antibodies for long-term protection.
