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 D
Explanation
Choice A: Quality of Education
Quality of education is an important factor in long-term health and socioeconomic status. However, it is not the immediate priority in this scenario. The client's report of skipping meals indicates an urgent need for addressing food insecurity, which directly impacts their health and well-being. Ensuring the client has access to adequate and nutritious food is essential for their immediate health needs and recovery.
Choice B: Economic Stability
Economic stability is crucial for long-term health and well-being, but it is not the most immediate concern in this scenario. Addressing food access will have a more direct and immediate impact on the client's health. Once the client's nutritional needs are met, the nurse can then work on connecting the client with resources to improve their economic stability.
Choice C: Health Care Illiteracy
Health care illiteracy refers to a lack of understanding about health information and services needed to make appropriate health decisions. While this is an important issue, it is not the immediate priority in this scenario. The client's report of skipping meals indicates an urgent need for addressing food insecurity, which directly impacts their health and well-being.
Choice D: Food Access
This is the correct choice. Food access is a critical issue because it directly affects the client's nutritional status and overall health. Skipping meals due to financial constraints can lead to malnutrition, weakened immune function, and delayed recovery from cellulitis. Ensuring the client has access to adequate and nutritious food is essential for their immediate health needs and recovery.
Correct Answer is D
Explanation
Choice A Reason:
Assessing the client's wound is a task that requires clinical judgment and expertise, which falls under the scope of practice of a registered nurse (RN) or licensed practical nurse (LPN). Assistive personnel (AP) are not trained or authorized to perform assessments, as these require a higher level of clinical knowledge and decision-making.
Choice B Reason:
Notifying the case manager of the client's wishes for community resources involves communication and coordination of care, which are responsibilities typically handled by an RN or LPN. This task requires understanding the client's overall care plan and the ability to communicate effectively with other healthcare professionals.
Choice C Reason:
Reviewing the client's medications is a task that involves understanding the medications, their purposes, potential side effects, and interactions. This requires clinical knowledge and judgment, which are beyond the scope of practice for AP. Medication review is typically performed by an RN or LPN.
Choice D Reason:
Assisting the client with bathing and oral care is a task that falls within the scope of practice for AP. These activities are part of the basic care tasks that AP are trained to perform. They involve helping the client with daily living activities, which do not require clinical judgment or decision-making.
