Based on the results of the study shown below, the epidemiologist has reason to worry because the incidence rate increased over four times the previous level as shown below:
- number of HIV cases = 440 persons
- new incidence rate = 2.25 per 1000 persons
<h3>What is prevalence and incidence rate?</h3>
Prevalence rate is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time.
- Prevalence rate = number of cases/total population × 100%
Incidence rate is the proportion of new cases of a condition observed within a given period of time.
- Incidence rate = number of new cases/population at risk × 1000
- population at risk = total population - previous cases
The number of people who had HIV in January 2012 is calculated as follows:
- number of HIV cases = prevalence rate × total population
number of HIV cases = 2.2% × 20000
number of HIV cases = 440 persons
Incidence rate between February 2012 and January 2013 is calculated as follows:
Incidence rate = 50/(20000 - 440) × 1000
Incidence rate = 2.25 per 1000 persons.
Based on the new incidence rate, the epidemiologist has reason to worry because the incidence rate has increased over four times the previous level.

Exercise is a subset of physical activity that is planned, structured, and repetitive and has as a final or an intermediate objective the improvement or maintenance of physical fitness. Physical fitness is a set of attributes that are either health- or skill-related.
According to the research, the nurse should explain that fats that are hydrogenated are trans fatty acids.
<h3>What are trans
fatty acids?</h3>
They are substances composed of the combination of fatty acids and glycerin that are usually generated from the hydrogenation of oils, being a substance considered harmful to health.
Hydrogenation is a process that, by adding hydrogen, allows an oil to be transformed into a solid fat, which is why many industrially processed food products, such as snacks, cookies and margarines, contain trans fats.
Therefore, we can conclude that according to the research, the nurse should explain that fats that are hydrogenated are trans fatty acids.
