A community health nurse is educating a newly licensed nurse about sensitivity and specificity using a two-by-two table. Which of the following statements by the newly licensed nurse indicates an understanding of the table related to false negatives?
False negatives are represented in the table cell that indicates the person does not have the disease and the test does not indicate disease.
False negatives are represented in the table cell that indicates the person has the disease and the test indicates the person has the disease.
False negatives are represented in the table cell that indicates the person has the disease and the test does not indicate disease.
False negatives are represented in the table cell that indicates the person does not have the disease and the test indicates disease.
The Correct Answer is C
Choice A Reason:
This statement is incorrect because it describes a true negative, not a false negative. A true negative occurs when the test correctly identifies that a person does not have the disease. In a two-by-two table, this is represented in the cell where both the actual status and the test result indicate no disease.
Choice B Reason:
This statement is incorrect because it describes a true positive, not a false negative. A true positive occurs when the test correctly identifies that a person has the disease. In a two-by-two table, this is represented in the cell where both the actual status and the test result indicate the presence of the disease.
Choice C Reason:
This statement is correct because it accurately describes a false negative. A false negative occurs when the test incorrectly indicates that a person does not have the disease when, in fact, they do. In a two-by-two table, this is represented in the cell where the actual status indicates the presence of the disease, but the test result indicates no disease.
Choice D Reason:
This statement is incorrect because it describes a false positive, not a false negative. A false positive occurs when the test incorrectly indicates that a person has the disease when, in fact, they do not. In a two-by-two table, this is represented in the cell where the actual status indicates no disease, but the test result indicates the presence of the disease.

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 C
Explanation
Choice A reason: There's no way to predict how a client will do on a medical regimen.
This statement is incorrect because the Theory of Reasoned Action/Planned Behavior (TRA/TPB) provides a framework for predicting and understanding behaviors, including adherence to medical regimens. According to this theory, behavioral intentions, influenced by attitudes, subjective norms, and perceived behavioral control, can predict actual behavior. Therefore, it is possible to predict how a client might adhere to a medical regimen based on these factors.
Choice B reason: There is a high chance of better outcomes with more education.
While education is important, it alone may not be sufficient to ensure better outcomes. The TRA/TPB suggests that intentions to perform a behavior are influenced by attitudes towards the behavior, subjective norms, and perceived behavioral control. Without addressing these factors, simply providing more education may not lead to improved adherence or outcomes.
Choice C reason: There is a higher chance of complications due to poor adherence to the plan.
This statement aligns with the TRA/TPB, which posits that poor adherence to a medical regimen can lead to negative health outcomes. In the context of diabetes management, poor adherence to dietary and exercise plans can result in uncontrolled blood glucose levels, leading to complications such as cardiovascular disease, neuropathy, and retinopathy. The client's reported lack of motivation and non-adherence to the meal plan and exercise regimen increases the risk of such complications.
Choice D reason: The outcomes will be about the same.
This statement is incorrect because it overlooks the impact of adherence on health outcomes. According to the TRA/TPB, adherence to recommended behaviors is crucial for achieving positive health outcomes. In diabetes management, adherence to dietary and exercise plans is essential for controlling blood glucose levels and preventing complications. Therefore, outcomes are unlikely to remain the same if the client does not adhere to the recommended regimen.
