A public 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 true positives?
"True positives are represented in the table cell that indicates the person does not have the disease and the test indicates disease."
"True positives are represented in the table cell that indicates the person has the disease and the test indicates the person has the disease."
"True positives are represented in the table cell that indicates the person has the disease and the test does not indicate disease."
"True positives are represented in the table cell that indicates the person does not have the disease and the test does not indicate disease."
The Correct Answer is B
Choice A: "True Positives are Represented in the Table Cell that Indicates the Person Does Not Have the Disease and the Test Indicates Disease."
This statement is incorrect. In a two-by-two table used to evaluate diagnostic tests, the cell representing true positives is where both the test result and the actual disease status are positive. This cell indicates that the test correctly identified individuals who have the disease. The statement here describes a false positive, where the test indicates disease, but the person does not actually have it.
Choice B: "True Positives are Represented in the Table Cell that Indicates the Person Has the Disease and the Test Indicates the Person Has the Disease."
This statement is correct. True positives are indeed represented in the cell where both the test result and the actual disease status are positive. This means the test has correctly identified individuals who have the disease. This cell is crucial for calculating the sensitivity of the test, which measures the proportion of actual positives correctly identified by the test.
Choice C: "True Positives are Represented in the Table Cell that Indicates the Person Has the Disease and the Test Does Not Indicate Disease."
This statement describes a false negative, where the person has the disease, but the test fails to detect it. This cell is used to calculate the test's sensitivity, but it does not represent true positives. False negatives are critical to understand because they indicate cases where the test missed the disease.
Choice D: "True Positives are Represented in the Table Cell that Indicates the Person Does Not Have the Disease and the Test Does Not Indicate Disease."
This statement describes true negatives, where the test correctly identifies individuals who do not have the disease. While true negatives are important for calculating the specificity of the test, they do not represent true positives. Specificity measures the proportion of actual negatives correctly identified by the test.

Correct Answer is D
Explanation
Choice A: Develop a Team Strategy
Developing a team strategy is an important step in the CHANGE model, but it is not the first step. Before a strategy can be developed, it is essential to have a team in place. The team will collaborate to create a strategy that aligns with the community's needs and goals.
Choice B: Gather Data
Gathering data is a crucial part of the community assessment process. However, it is not the initial step in the CHANGE model. Data collection comes after the team has been assembled and a strategy has been developed. The team needs to be in place to determine what data is needed and how it will be collected.
Choice C: Build the Community Action Plan
Building the community action plan is a later step in the CHANGE model. This step involves using the data collected to develop a plan that addresses the community's health needs. The action plan is created after the team has been assembled, a strategy has been developed, and data has been gathered.
Choice D: Assemble the Team
This is the correct first step in the CHANGE model. Assembling the team involves bringing together a diverse group of stakeholders who will work collaboratively to assess the community and develop an action plan. The team typically includes representatives from various sectors of the community, such as health care, education, business, and local government.
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.
