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 Reason:
Conducting a physical examination is the first step in addressing the employee's concern about hearing loss. This examination allows the nurse to assess the ear for any visible issues, such as earwax buildup, infection, or structural abnormalities. A thorough physical examination can help identify the cause of the hearing loss and determine the appropriate next steps. It is essential to rule out any immediate and easily treatable conditions before proceeding with more specialized interventions.
Choice B Reason:
Irrigating the ear to remove any obstruction, such as earwax, can be an effective treatment for hearing loss caused by cerumen impaction. However, this should only be done after a physical examination confirms that earwax is the cause of the hearing loss. Irrigation without proper assessment can potentially cause harm, especially if there is an underlying infection or perforation of the eardrum.
Choice C Reason:
Advising the client on the use of ear plugs is a preventive measure to protect hearing, particularly in noisy environments. However, this advice does not address the immediate concern of unilateral hearing loss. Ear plugs are more relevant for preventing further hearing damage rather than diagnosing or treating existing hearing issues.
Choice D Reason:
Referring the client to an audiologist is an important step if the initial physical examination does not reveal the cause of the hearing loss or if the hearing loss persists despite initial treatment. Audiologists specialize in diagnosing and treating hearing disorders and can perform comprehensive hearing tests. However, this referral should come after the nurse has conducted a preliminary assessment to rule out any obvious and treatable causes.
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.
