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 B
Explanation
Choice A: Public Health
Public health focuses on protecting and improving the health of populations through education, policy-making, and research for disease and injury prevention. It typically operates within a specific country or community, addressing local health issues and promoting healthy lifestyles. While public health initiatives can have international implications, they are generally not centered on international collaboration to the same extent as global health.
Choice B: Global Health
Global health is defined as the area of study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide. It emphasizes international collaboration and a multidisciplinary approach to address health issues that transcend national boundaries. Global health initiatives often involve partnerships between countries, international organizations, and various sectors to tackle health disparities and improve health outcomes globally.
Choice C: Community Health
Community health focuses on the health status and needs of specific communities or populations within a defined geographic area. It involves the development and implementation of strategies to improve the health and well-being of community members. While community health can contribute to broader public health goals, it does not typically involve the same level of international collaboration as global health.
Choice D: Population Health
Population health refers to the health outcomes of a group of individuals, including the distribution of such outcomes within the group. It aims to improve the health of an entire population by addressing a wide range of factors that influence health, such as social, economic, and environmental determinants. Population health strategies can be applied at local, national, or global levels, but the term itself does not specifically imply international collaboration.
Correct Answer is A
Explanation
Choice A Reason:
Identifying a support system to prevent the client from giving into the urge to smoke is crucial during the preparation phase of the Transtheoretical Model. In this phase, the client is ready to take action within the next 30 days and may start taking small steps towards quitting smoking. A support system, which can include family, friends, or support groups, provides the necessary encouragement and accountability to help the client stay committed to their goal. This support can significantly increase the chances of successful smoking cessation by offering emotional and practical assistance².
Choice B Reason:
Giving literature to the client who has expressed wanting to quit but is not yet ready to do so aligns more with the contemplation phase of the Transtheoretical Model. In the contemplation phase, individuals are considering quitting within the next six months but are not yet ready to take immediate action. Providing educational materials can help them understand the benefits of quitting and the steps involved, but it is not as relevant for someone in the preparation phase who is already planning to quit soon.
Choice C Reason:
Consoling the client for smoking a cigarette after having quit smoking 4 months ago is more appropriate for the maintenance phase. In the maintenance phase, individuals work to sustain their behavior change and prevent relapse. While offering support after a relapse is important, it does not align with the preparation phase, where the focus is on planning and preparing to quit smoking.
Choice D Reason:
Teaching the client who refuses to quit smoking about fire safety and cigarette smoking is not relevant to the preparation phase. This intervention might be more suitable for individuals in the precontemplation phase, where they are not yet considering quitting and need to be made aware of the risks associated with smoking. In the preparation phase, the client is already motivated to quit, so the focus should be on supporting their efforts to take action.
