Observational Study Designs
A clinical pediatric nurse has noticed a rise in childhood cancer diagnoses among the Hispanic population served by the local clinic. The nurse is concerned about this increase in cancer incidence in the patient population and turns to the literature to explore current research on this topic. The nurse finds through the reading that there appears to be an association between parental smoking and childhood cancer and wonders if this could be the cause of the rise in cases.
This type of suspected association between a risk factor (exposure) and a particular outcome (childhood cancer) can be evaluated using an observational study design. This week, you were introduced to observational study designs used in epidemiology. For this Discussion, you will identify an epidemiologic association of interest (e.g., smoking and lung cancer, obesity and heart disease, hormone replacement/modification therapy and breast cancer) and determine an appropriate observational study design for exploring that association.
To prepare:
- Review the different types of observational study designs presented in the Learning Resources: ecologic, cross-sectional, case-control, and cohort.
- Carefully examine the characteristics, strengths, and limitations of each design.
- Consider an association between a risk factor and a particular health outcome that is of interest to you. Then, select the observational study design you think would be the most appropriate for exploring this association.
- Consider how using observational study designs can lead to improvements in population health.
By tomorrow 03/14/2018 12 noon, write a minimum of 550 words in APA format with at least 3 scholarly references from the list of required readings below. Include the level one headings as numbered below:
Post a cohesive response that addresses the following:
1) Identify the association between the risk factor and health outcome you selected and suggest which observational study design you feel is most appropriate for examining that association.
2) Support your selection of the observational design, noting its strengths and limitations for addressing the health problem.
3) What might you be able to learn by using your selected study design that might lead to improvements in population health? Support your response with evidence from the literature.

In the chapter, the authors address three varieties of observational studies—ecological, cross-sectional, and case control. Chapter 7 addresses cohort studies, another form of observational design.

/in Uncategorized /by developerDiscussion: Health Promotion During Pregnancy
When caring for pregnant women, it is important to care for the whole person. This means you not only manage the pregnancy and treat conditions, but you also promote healthy behaviors and good lifestyle choices. Through health promotion, you can help to ensure the safety of both the mother and the baby. Your role in health promotion is to identify health risks that might result in pregnancy complications, educate patients on these risks, and provide the necessary support to help patients mitigate these risks. In this Discussion, you examine implications of drug use, alcohol consumption, dietary habits, and environmental exposures during pregnancy, and you consider ways to educate pregnant women about such risks.
To prepare:
By Day 3
Post a detailed description of the educational media piece you would create for health promotion during pregnancy. Explain why you selected the particular topic, as well as why you selected the type of media and how and why it is suitable for your patient population.

Ocate A Model Of Practice That You Could Apply To Nursing
/in Uncategorized /by developerModels of Practice
What is a model?
A model demonstrates the researcher’s interpretation of how concepts are related to one another and are developed based on qualitative research. Models often are precursors to theory development.
Three of the most prominent nursing models categorized as focusing on goals and functions include Florence Nightingale’s environmental model of nursing, Dorothy Johnson’s behavioral system model, and Nola J. Pender’s health promotion model.
Directions
In this assignment, you will locate a model of practice that you could apply to nursing. It does not need to be a nursing model. Models of practice can be found in leadership, business, education, and technology. You will explain why you have chosen the model and apply the model to your advanced practice role in the template provided.
In the first row, in the first column, write the name of your chosen model. An example has been provided in the first rows to guide you. Please remove the examples when entering your information
In the first column of the template table, list the characteristics of the model you have chosen with a source/s of support. In the second column, list an application to your advanced nursing practice role upon graduation with a source of support/s.
Assignment Details
For this Assignment, your paper must be 2 to 3 pages, not including the title and reference pages.
