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 B
Explanation
Choice A Reason:
The client reports there are bike paths or running trails in their community. This statement indicates a positive aspect of the built environment. The presence of bike paths and running trails promotes physical activity and overall well-being. It does not suggest any faults in the built environment.
Choice B Reason:
The client reports contaminants in their drinking water at home. This statement clearly indicates a faulty built environment. Contaminated drinking water poses significant health risks and reflects poor infrastructure or inadequate maintenance of water supply systems. Ensuring access to clean and safe drinking water is a fundamental aspect of a healthy built environment.
Choice C Reason:
The client reports that there is limited public parking on their street. While limited public parking can be an inconvenience, it does not directly indicate a faulty built environment. Parking availability is more related to urban planning and transportation policies rather than the overall quality of the built environment.
Choice D Reason:
The client reports a lack of community centers in their neighborhood. Although the absence of community centers can affect social interactions and community engagement, it does not necessarily indicate a faulty built environment. It highlights a gap in community resources but does not directly impact the safety or health of the environment.
Correct Answer is C
Explanation
Choice A: The Workplace Procedures and Protocols Manual
Reviewing the workplace procedures and protocols manual can provide valuable context about the standard operating procedures and safety measures in place at the factory. However, this information alone does not directly address the specifics of the employee's injury claim. It is more useful for understanding the general safety environment rather than investigating a specific incident.
Choice B: The Occupational Safety and Health Act
The Occupational Safety and Health Act (OSHA) provides guidelines and regulations for workplace safety. While it is important for ensuring compliance with safety standards, it does not contain specific information about individual employee injury claims. The nurse should be familiar with OSHA regulations but needs more detailed information about the specific incident to conduct a thorough investigation.
Choice C: The Client's Medical Record or Chart
This is the correct choice. The client's medical record or chart contains detailed information about the employee's health status, medical history, and the specifics of the injury. Reviewing this information is crucial for understanding the nature and extent of the injury, any pre-existing conditions, and the treatment provided. This data is essential for accurately assessing the validity of the injury claim and determining any potential workplace-related factors.
Choice D: The Client's Attendance Record at Health and Safety Seminars
While the client's attendance record at health and safety seminars can indicate their level of training and awareness of safety protocols, it does not provide direct information about the injury itself. This record can be useful for understanding the employee's knowledge of safety practices but is not sufficient for investigating the specifics of the injury claim.
