A community health nurse is using the United States Preventive Services Task Force (USPSTF) guidelines to recommend health screenings for a client. The nurse should identify which of the following descriptions applies to Grade C screenings?
Research indicates this screening is not warranted at this time and may, in fact, be harmful.
Research indicates this screening exam has a small benefit.
There is not enough evidence to determine if this screening is helpful or not
Research indicates this screening exam is beneficial.
The Correct Answer is B
Choice A Reason:
Research indicating that a screening is not warranted at this time and may be harmful aligns with a Grade D recommendation from the USPSTF. Grade D recommendations suggest that the service has no net benefit or that the harms outweigh the benefits, and therefore, it should be discouraged.
Choice B Reason:
A Grade C recommendation from the USPSTF means that the service should be selectively offered or provided to individual patients based on professional judgment and patient preferences. There is at least moderate certainty that the net benefit is small. This means that while there is some benefit, it is not substantial enough to recommend the service for all individuals.
Choice C Reason:
The statement that there is not enough evidence to determine if a screening is helpful or not corresponds to a Grade I (Insufficient) recommendation. This grade indicates that the current evidence is insufficient to assess the balance of benefits and harms of the service. More research is needed to make a definitive recommendation.
Choice D Reason:
Research indicating that a screening exam is beneficial aligns with a Grade A or B recommendation. Grade A recommendations suggest high certainty that the net benefit is substantial, while Grade B recommendations suggest high certainty that the net benefit is moderate or there is moderate certainty that the net benefit is moderate to substantial.

Correct Answer is A
Explanation
Choice A: Hearing Loss
Hearing loss is a common pathophysiology among manual labor workers due to exposure to high levels of noise in the workplace. Prolonged exposure to loud machinery, tools, and equipment can lead to noise-induced hearing loss (NIHL). This condition is preventable with proper use of hearing protection and adherence to occupational safety guidelines.
Choice B: Multiple Sclerosis
Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system. It is not typically associated with environmental pollutants or hazardous exposure in the workplace. MS is believed to be caused by a combination of genetic and environmental factors, but it is not a common condition among manual labor workers due to occupational hazards.
Choice C: Influenza
Influenza is a viral infection that affects the respiratory system. While manual labor workers can contract influenza, it is not directly related to hazardous exposure or environmental pollutants in the workplace. Influenza is more commonly spread through person-to-person contact and is preventable through vaccination and good hygiene practices.
Choice D: Alopecia
Alopecia refers to hair loss, which can be caused by various factors including genetics, autoimmune conditions, and stress. It is not typically associated with hazardous exposure or environmental pollutants in the workplace. Manual labor workers are not at a higher risk of developing alopecia due to their occupational environment.
Correct Answer is A
Explanation
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.
