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.

Answer and Explanation

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 D

Explanation

Choice A Reason:
Asking if the client has an immunization card for documentation is important for record-keeping and ensuring that the client's vaccination history is up-to-date. However, this question does not directly address the safety of administering the vaccine. The primary concern for safety is identifying any potential allergies or adverse reactions.

Choice B Reason:
Inquiring if there are any questions regarding the client's vaccine schedule is helpful for clarifying any doubts and ensuring the client understands their vaccination plan. While this is important for overall vaccine management, it does not specifically address immediate safety concerns related to administering the vaccine.

Choice C Reason:
Asking if the client has a site preference for vaccine administration can enhance the client's comfort and experience. However, this question is more about personal preference and does not impact the safety of the vaccine administration process.

Choice D Reason:
If they have had any past issues or allergies to the vaccine. This is the most critical question for ensuring safety. Identifying any previous adverse reactions or allergies to vaccines is essential to prevent potential allergic reactions or other complications. This information allows the nurse to take necessary precautions or choose an alternative vaccine if needed, ensuring the client's safety during immunization.

A. "When the exposure is decreased or eliminated, the risk of disease declines or is eliminated." B. "The exposure must come before the disease develops. C. "A relationship is biologically possible, and it makes sense." D. "Increased exposure increases the risk of developing the disease."

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.
