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 C
Explanation
Choice A: Order a New Medication
Ordering a new medication is not typically the first step in the protocol for an employee injury. The nurse needs to assess the injury and determine the appropriate course of action based on the severity and nature of the injury. Medication may be part of the treatment plan, but it is not the initial step in the injury protocol.
Choice B: Initiate Safety and Audit Checks
Initiating safety and audit checks is an important part of workplace safety management, but it is not the immediate response to an employee injury. These checks are usually conducted to prevent future incidents and ensure compliance with safety regulations. The immediate priority is to address the employee's injury and provide necessary medical care.
Choice C: Perform a Drug Test
This is the correct choice. Performing a drug test is often part of the protocol following a workplace injury, especially in industries where safety is a critical concern. The drug test helps determine if substance use may have contributed to the accident. It is a standard procedure to ensure workplace safety and compliance with regulations.
Choice D: Vet the Injured Worker
Vetting the injured worker is not a standard part of the protocol for handling an employee injury. The focus should be on providing immediate medical care and assessing the injury. Vetting typically refers to a thorough examination or background check, which is not relevant in the context of responding to an injury.
Correct Answer is B
Explanation
Choice A Reason:
The client still journaling their feelings about their sister's death 7 years ago indicates ongoing grief, which is important but may not be the immediate priority. Grieving is a natural process, and while it can impact mental health, it does not pose an immediate threat to the client's safety or daily functioning. Addressing grief can be part of a longer-term mental health support plan.
Choice B Reason:
The client experiencing cyberbullying is the priority because it can have severe and immediate impacts on mental health, including anxiety, depression, and suicidal thoughts. Cyberbullying can lead to significant emotional distress and requires prompt intervention to ensure the client's safety and well-being. Addressing this issue can help prevent further psychological harm and support the client's mental health.
Choice C Reason:
The client primarily eating fast food while living on a limited budget is a concern for long-term health, including risks of obesity, diabetes, and other chronic conditions. However, it does not pose an immediate threat to the client's safety. Nutritional counseling and support can be provided as part of a broader health plan.
Choice D Reason:
The client missing classes due to suffering from seasonal allergies is a health concern that can affect academic performance and quality of life. However, it is typically manageable with appropriate medical treatment and does not pose an immediate threat to the client's safety. Addressing allergies can be part of a comprehensive health management plan.
