A community health nurse is preparing an in-service for staff to define the conditions of causation in epidemiology studies. Which of the following descriptions should the nurse use to define a cessation of exposure to establish causation?

"When the exposure is decreased or eliminated, the risk of disease declines or is eliminated."

"The exposure must come before the disease develops.

"A relationship is biologically possible, and it makes sense."

"Increased exposure increases the risk of developing the disease."

Answer and Explanation

The Correct Answer is A

Choice A: "When the Exposure is Decreased or Eliminated, the Risk of Disease Declines or is Eliminated."
This statement accurately describes the concept of cessation of exposure in establishing causation. According to the Bradford Hill criteria, if a factor is truly causal, reducing or eliminating exposure to that factor should lead to a decrease in the incidence of the disease. This principle helps to confirm the causal relationship between the exposure and the disease.

Choice B: "The Exposure Must Come Before the Disease Develops."
This statement refers to the temporal relationship criterion in the Bradford Hill criteria, which states that for an exposure to be considered causal, it must precede the onset of the disease. While this is an important aspect of establishing causation, it does not specifically address the concept of cessation of exposure.

Choice C: "A Relationship is Biologically Possible, and it Makes Sense."
This statement pertains to the biological plausibility criterion, which suggests that the observed association between an exposure and a disease should be consistent with existing biological and medical knowledge. While biological plausibility is crucial for establishing causation, it does not directly relate to the cessation of exposure.

Choice D: "Increased Exposure Increases the Risk of Developing the Disease."
This statement describes the dose-response relationship, another criterion in the Bradford Hill framework. It indicates that a greater level of exposure to a risk factor should correspond to a higher risk of developing the disease. Although this is an important aspect of causation, it does not specifically address the cessation of exposure.

Correct Answer is C

Explanation

Choice A Reason:
Teaching residents about the dangers of lead-based paint is an important public health intervention, especially in older neighborhoods where lead paint may still be present. However, this intervention does not directly address the mobility and transportation issues faced by elderly residents with health problems. It is more relevant to preventing lead poisoning and ensuring safe living environments.

Choice B Reason:
Partnering with local churches and writing grants for childcare funding towards affordable daycares is a valuable community initiative. It supports working families by providing affordable childcare options. However, this intervention does not directly benefit elderly residents with health issues who have trouble getting around. It is more focused on supporting young families rather than addressing the specific needs of the elderly.

Choice C Reason:
Advocating for more transportation to healthcare facilities directly addresses the mobility challenges faced by elderly residents with health issues. Improved transportation options can significantly enhance their access to medical care, ensuring they receive timely treatments and check-ups. This intervention is crucial for maintaining their health and well-being, making it the most relevant and impactful choice for this scenario.

Choice D Reason:
Partnering with a nonprofit organization for the local farmers' market to sell fresh produce twice a week is an excellent initiative to improve access to healthy foods. While this can benefit the elderly by providing easier access to nutritious food, it does not directly address their transportation and mobility issues. It is a supportive measure but not the primary solution for their immediate needs.

A. Conduct a physical examination. B. Irrigate the ear to remove any obstruction. C. Advise the client on the use of ear plugs. D. Refer the client to an audiologist.

Correct Answer is A

Explanation

Choice A Reason:
Conducting a physical examination is the first step in addressing the employee's concern about hearing loss. This examination allows the nurse to assess the ear for any visible issues, such as earwax buildup, infection, or structural abnormalities. A thorough physical examination can help identify the cause of the hearing loss and determine the appropriate next steps. It is essential to rule out any immediate and easily treatable conditions before proceeding with more specialized interventions.

Choice B Reason:
Irrigating the ear to remove any obstruction, such as earwax, can be an effective treatment for hearing loss caused by cerumen impaction. However, this should only be done after a physical examination confirms that earwax is the cause of the hearing loss. Irrigation without proper assessment can potentially cause harm, especially if there is an underlying infection or perforation of the eardrum.

Choice C Reason:
Advising the client on the use of ear plugs is a preventive measure to protect hearing, particularly in noisy environments. However, this advice does not address the immediate concern of unilateral hearing loss. Ear plugs are more relevant for preventing further hearing damage rather than diagnosing or treating existing hearing issues.

Choice D Reason:
Referring the client to an audiologist is an important step if the initial physical examination does not reveal the cause of the hearing loss or if the hearing loss persists despite initial treatment. Audiologists specialize in diagnosing and treating hearing disorders and can perform comprehensive hearing tests. However, this referral should come after the nurse has conducted a preliminary assessment to rule out any obvious and treatable causes.
