A public health nurse is participating in a research study to determine how virulent a new virus is. Which of the following mortality measures should the nurse use to calculate this data?
Cause-specific mortality rate
Age-specific mortality rate*
Proportionate mortality
Case fatality
The Correct Answer is D
Choice A Reason:
The cause-specific mortality rate measures the number of deaths attributed to a specific cause within a population during a given time period. While this measure is useful for understanding the impact of a particular disease on a population, it does not directly indicate the virulence of a virus. Virulence refers to the severity or harmfulness of a disease, which is better captured by the case fatality rate.
Choice B Reason:
The age-specific mortality rate calculates the number of deaths within specific age groups in a population. This measure helps identify age-related mortality trends but does not provide information about the virulence of a virus. Age-specific mortality rates are more useful for understanding the impact of diseases across different age demographics rather than assessing the severity of a new virus.
Choice C Reason:
Proportionate mortality refers to the proportion of deaths in a population attributable to a specific cause relative to all deaths. This measure helps in understanding the relative importance of different causes of death but does not directly measure the virulence of a virus. Proportionate mortality is more about the distribution of causes of death rather than the severity of a particular disease.
Choice D Reason:
Case fatality rate (CFR) is the most appropriate measure for determining the virulence of a new virus. CFR is calculated by dividing the number of deaths caused by the disease by the number of diagnosed cases of the disease, then multiplying by 100 to get a percentage. This measure directly indicates the lethality of the virus by showing the proportion of diagnosed cases that result in death. It is a critical indicator for assessing the severity and potential impact of a new infectious disease.

Correct Answer is A
Explanation
Choice A Reason:
The nurse should review the state laws to determine if and how this information should be shared with the National Notifiable Disease Surveillance System. This is the correct answer because HIV is a notifiable disease, meaning that cases must be reported to public health authorities to monitor and control the spread of the infection. Each state has specific laws and regulations regarding the reporting of notifiable diseases, and it is crucial for the nurse to be aware of these requirements to ensure compliance and public health safety.
Choice B Reason:
The nurse should recognize this diagnosis as an indication that the outreach program is not successful. This statement is incorrect. A positive diagnosis does not necessarily mean that the outreach program is unsuccessful. On the contrary, identifying and linking individuals to care is a key objective of such programs. The success of the program can be measured by its ability to reach high-risk individuals, provide testing, and ensure they receive appropriate care and support.
Choice C Reason:
Outside the healthcare team, the nurse should keep this diagnosis confidential. While confidentiality is critical in healthcare, the reporting of notifiable diseases like HIV is an exception due to public health concerns. The nurse must balance confidentiality with the legal obligation to report the diagnosis to public health authorities. This ensures that appropriate measures can be taken to prevent further transmission and provide necessary public health interventions.
Correct Answer is C
Explanation
Choice A reason: There's no way to predict how a client will do on a medical regimen.
This statement is incorrect because the Theory of Reasoned Action/Planned Behavior (TRA/TPB) provides a framework for predicting and understanding behaviors, including adherence to medical regimens. According to this theory, behavioral intentions, influenced by attitudes, subjective norms, and perceived behavioral control, can predict actual behavior. Therefore, it is possible to predict how a client might adhere to a medical regimen based on these factors.
Choice B reason: There is a high chance of better outcomes with more education.
While education is important, it alone may not be sufficient to ensure better outcomes. The TRA/TPB suggests that intentions to perform a behavior are influenced by attitudes towards the behavior, subjective norms, and perceived behavioral control. Without addressing these factors, simply providing more education may not lead to improved adherence or outcomes.
Choice C reason: There is a higher chance of complications due to poor adherence to the plan.
This statement aligns with the TRA/TPB, which posits that poor adherence to a medical regimen can lead to negative health outcomes. In the context of diabetes management, poor adherence to dietary and exercise plans can result in uncontrolled blood glucose levels, leading to complications such as cardiovascular disease, neuropathy, and retinopathy. The client's reported lack of motivation and non-adherence to the meal plan and exercise regimen increases the risk of such complications.
Choice D reason: The outcomes will be about the same.
This statement is incorrect because it overlooks the impact of adherence on health outcomes. According to the TRA/TPB, adherence to recommended behaviors is crucial for achieving positive health outcomes. In diabetes management, adherence to dietary and exercise plans is essential for controlling blood glucose levels and preventing complications. Therefore, outcomes are unlikely to remain the same if the client does not adhere to the recommended regimen.
