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 C
Explanation
Choice A: "I Think That I Missed Two Math Tutoring Classes Last Week, But I Can Still Catch Up."
This statement indicates that the client is aware of their academic responsibilities and is optimistic about catching up. Missing a couple of classes is not uncommon, and the client's positive attitude towards catching up is a good sign. This statement does not indicate an immediate need for intervention regarding their mental health.
Choice B: "I Have Not Used Drugs in 6 Weeks."
This statement is positive and indicates progress in the client's efforts to stay away from substance use. It shows that the client is making strides towards healthier behaviors, which is a crucial aspect of their overall well-being. This statement does not require immediate intervention but should be acknowledged and supported.
Choice C: "I Don't Have Anyone I Can Talk to About My Problems."
This statement is concerning and indicates a lack of social support, which is critical for someone with a history of depression and suicidal ideation. Feeling isolated and having no one to talk to can exacerbate feelings of depression and increase the risk of suicidal thoughts. This statement requires immediate intervention to ensure the client receives the necessary support and resources to address their feelings of isolation.
Choice D: "I Have Been Participating in My Local YMCA After-School Dance Program Again."
This statement is positive and indicates that the client is engaging in social and physical activities, which can be beneficial for their mental health. Participation in such programs can provide a sense of community, improve mood, and reduce feelings of isolation. This statement does not require immediate intervention but should be encouraged and supported.
Correct Answer is D
Explanation
Choice A Reason:
Assessing the client's wound is a task that requires clinical judgment and expertise, which falls under the scope of practice of a registered nurse (RN) or licensed practical nurse (LPN). Assistive personnel (AP) are not trained or authorized to perform assessments, as these require a higher level of clinical knowledge and decision-making.
Choice B Reason:
Notifying the case manager of the client's wishes for community resources involves communication and coordination of care, which are responsibilities typically handled by an RN or LPN. This task requires understanding the client's overall care plan and the ability to communicate effectively with other healthcare professionals.
Choice C Reason:
Reviewing the client's medications is a task that involves understanding the medications, their purposes, potential side effects, and interactions. This requires clinical knowledge and judgment, which are beyond the scope of practice for AP. Medication review is typically performed by an RN or LPN.
Choice D Reason:
Assisting the client with bathing and oral care is a task that falls within the scope of practice for AP. These activities are part of the basic care tasks that AP are trained to perform. They involve helping the client with daily living activities, which do not require clinical judgment or decision-making.
