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 Reason:
The quick and colorful approach is a method often used for brainstorming and generating ideas in a visually engaging manner. It involves using colorful charts, sticky notes, and other visual aids to help participants think creatively and organize their thoughts. However, this method does not typically involve the use of questionnaires for data collection.
Choice B Reason:
The simplex method is a mathematical approach used for linear programming and optimization problems. It helps in finding the best possible solution from a set of feasible solutions. This method is highly analytical and does not involve the use of questionnaires for data collection or analysis.
Choice C Reason:
The criteria weighting method is used to evaluate and prioritize different options based on specific criteria. Participants assign weights to each criterion based on its importance, and then score each option against these criteria. While this method is useful for decision-making, it does not inherently involve the use of questionnaires for data collection.
Choice D Reason:
Nominal group planning is a structured method for group brainstorming that encourages contributions from everyone. It involves the use of questionnaires to gather individual opinions and then aggregates these responses to identify the most important issues or solutions. This method is particularly effective for prioritizing community needs as it ensures that all voices are heard and considered.
Correct Answer is A
Explanation
Choice A: Crime Statistics
Crime statistics are an example of secondary data. Secondary data refers to information that has been collected by someone else for a different purpose but is being utilized by the nurse for community assessment. Crime statistics are typically gathered by law enforcement agencies and other governmental bodies and can provide valuable insights into the safety and social environment of a community.
Choice B: Direct Observation
Direct observation is a method of collecting primary data. Primary data is gathered firsthand by the researcher through direct methods such as surveys, interviews, or observations. In this case, the nurse would be directly observing the community to gather information, making it a primary data collection method.
Choice C: Community Informant Interviews
Community informant interviews are another example of primary data collection. These interviews involve speaking directly with community members or key informants to gather firsthand information about the community's health needs, resources, and concerns. This method provides qualitative data that can be used to understand the community's perspective.
Choice D: Windshield Survey
A windshield survey is a primary data collection method where the nurse drives through the community to observe various aspects such as housing conditions, availability of services, and general environmental conditions. This type of survey provides firsthand observational data about the community.
