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: Studies show a minimal increase in confidence levels among mentored youth
While mentorship can have various benefits, the statement that it shows only a minimal increase in confidence levels is not entirely accurate. Research indicates that mentorship programs can significantly boost self-esteem and self-confidence among youth. However, this choice does not directly address the primary rationale for referring a disruptive student to a mentorship program.
Choice B reason: Students who are mentored are more likely to attain educational success
This statement is supported by extensive research. Mentorship programs have been shown to improve academic performance, increase high school graduation rates, and enhance overall educational aspirations. Mentored students often receive guidance, support, and motivation that help them succeed academically. This rationale aligns well with the goal of addressing disruptive behavior in school by providing positive role models and support systems.
Choice C reason: Mentored teens tend to recover better from bullying experiences
Mentorship can indeed help teens recover from bullying by providing emotional support and guidance. Mentors can offer a safe space for mentees to discuss their experiences and develop coping strategies. However, while this is a valid benefit of mentorship, it is not the primary rationale for referring a disruptive student to a mentorship program.
Choice D reason: Mentorship will help the child avoid social activities during the teen years
This statement is incorrect. Mentorship programs aim to encourage positive social interactions and engagement in constructive activities. They do not seek to isolate children from social activities but rather to guide them towards healthier and more productive social engagements. Therefore, this rationale does not support the referral for mentorship.
Correct Answer is D
Explanation
Choice A reason: "I will not know if I am going to be in the intervention or control group."
This statement indicates a misunderstanding of the nature of a cross-sectional study. Cross-sectional studies involve observing a specific population at a single point in time to gather data on various variables. There are no intervention or control groups in such studies, as they do not involve experimental manipulation or longitudinal follow-up.
Choice B reason: "The study will last for 10 years. You will contact me annually for an interview and blood work."
This statement describes a longitudinal study, not a cross-sectional study. Longitudinal studies involve repeated observations of the same variables over an extended period. Cross-sectional studies, on the other hand, collect data at one specific point in time, making this statement incorrect.
Choice C reason: "You'll need to find other participants like me but who do not have this disease."
This statement suggests a case-control study design, where participants with a specific condition (cases) are compared to those without the condition (controls). Cross-sectional studies do not require such comparisons; they simply collect data from a population at a single point in time to analyze the prevalence of certain characteristics or conditions.
Choice D reason: "The survey will take an hour to complete and then I'll be done."
This statement accurately reflects the nature of a cross-sectional study. These studies typically involve a one-time data collection process, such as a survey or interview, to gather information on various variables. Once the survey is completed, the participant's involvement in the study is finished, making this the correct understanding of a cross-sectional study.
