Answer:
Incidence
Explanation:
Isaac will need to assess the incidence rate of HIV-infected adolescents for his research. This must be done because Isaac's research wants to gauge the speed with which this virus is spreading among teens. For this, Isaac must make a comparison between the existing number of patients who fit this case, with patients who fit the recent cases of incidence of the disease. That is, when conducting his research, he will want to examine the number of new cases, the incidence of the disease.

The best answer to the question: Which statements made by the nursing students indicate understanding regarding the presence of surfactant, would be, B: 3, 4 and 5.
Explanation:
Pumonary surfactant is a lipoprotein substance that is present in the alveoli of the lungs and which ensure that the process of breathing is possible. Pulmonary surfactant is vital in neonates, and when they are born prematurely, surfactant will be provided so that the neonate can breathe normally, once he/she comes out of the wound. Without this administration, breathing for the newborn will not be possible. Surfactant helps to ensure lung compliance, ir prevents atelectasia (collapse of the lungs) during exhalation and it also helps to recruit collapsed alveoli. It is also a means by which gas exchange between the air and the lungs is increased, improving the exchange of O2 and CO2 and finally, it is important for immunity in the lungs. Understanding all this is vital for any nurse, and especially pediatric nurses.
Answer:
High rates of illness among the population and poor access to health care don’t just burden society, they also drive economic costs higher. A major contributor to the rise is the gap in health status known to exist between ethnic minorities and other groups, health researchers say.
One way to help reduce inequities in health and save health care dollars is to increase the proportion of ethnic minorities in the health professions workforce, and, in so doing, provide more culturally sensitive care, said Louis Sullivan, M.D., a former secretary of the U.S. Department Health and Human Services. Sullivan gave the keynote address at the Diversity Dialogue and Student Symposium on Health Professions held recently at the University of Florida Health Science Center.
The U.S. spends trillions on health care each year, reaching $2.5 trillion in 2009, according to an analysis in the public policy journal Health Affairs. A large fraction of that is attributable to health inequities, experts say. For example, from 2003 to 2006, health inequities accounted for $1 trillion in indirect costs associated with illness and premature deaths, according to a study commissioned by the Joint Center for Political and Economic Studies.
