A 16-year-old female high-school student is receiving treatment for Addison’s disease. The student confided in the school RN that she is going to stop taking her prednisone because it makes her feel “ugly.” She states she is depressed and embarrassed to be at school because of the side effects caused by the medication. After further review of the situation, the RN determines an interprofessional team should be convened to address the student's needs.
Initial Discussion Post:
Address the following:
Describe three (3) significant side effects of corticosteroid treatment for Addison’s disease.
Which factors make having Addison’s disease especially problematic for adolescents and why?
Discuss why an interprofessional team is appropriate for this situation, who should be included on the team, and the role of the RN on the team.

A study reported that 28 percent of middle school students in a certain state participate in community service activities. A teacher believes that the rate is greater than 28 percent for the middle school students in the teacher’s district. The teacher selected a random sample of middle school students from the district, and the percent of students in the sample who participated in community service activities was found to be 32 percent. Which of the following is the most appropriate method for investigating the teacher’s belief?
A two-sample z-test for a difference in population proportions A
A two-sample z-test for a difference in sample proportions B
A one-sample z-test for a sample proportion C
A one-sample z-test for a population proportion D
A one-sample z -test for a difference in population proportions E

A company that manufactures small lathes is interested in establishing standards for employees. A random sample of 18 employees is selected in order to develop the standards. The data collected is below. A manager at the firm feels that assembly time is related to intelligence. She feels that employees who did well in high school (as measured by high school averages) should be able to do the job faster. Does the data support her hunch?

Imagine Penn State were to hold summer events for High school students. Should it include freshman and sophomores? Or be open to all high school students & their families titled "College 101." What should Penn State do? What do families and students need to know at that point in their highschool to start considering? Who should they listen to? What do you wish you would have known then to help set you up for success? Would a panel discussion be helpful? If so, what panels? College admissions essay reviewers? College students? What should they see? Is there anything they should know about why you chose Penn State? Since it's high school and most of the students would be local, what are some selling points?

Exam scores for a population were standardized with a population
mean (µ) of 500 and a population standard deviation (σ) of 100 on
both the Math and Verbal portions. The following questions refer to
the Math portion;
a) A highly selective school decides that it will consider only
applicants with a score in the top 5%. What will be the minimum
score that you must have in order to be considered for admission to
this school?
b) If 1 million students took the exam, how many of these students
would be viable applicants to this school?
4a. The mean weight of 140 6th graders is 80 lbs with a standard
deviation of 8 lbs. Calculate the standard error of the mean.
b. Using the mean and standard deviation from Q4a, calculate the
proportion (percentage) of 7th graders that will have weights
between 74 lbs and 84 lbs?

If a graduate does well while in school and graduates happy, they are more likely to be able to find a satisfying job. Post-graduation can be hard for some students because there is often time a gap between school and finding employment. The happier a student is while in school and at graduation, the easier it is for them to find employment that they can apply their degree to. By looking at the graduate employment rate, the college can judge if they are fulfilling its mission and goals of providing a strong education and satisfying the community.
One of the Key Performance Indicators for our project is the "Graduate employment rate" as explained above. How can we measure the Graduate employment rate? for example, should we email them 6 months and 1 year after their graduation to see if they have found a job? What would be three Hawthorne effects of this KPI?

Christina is a 17-year-old gravida 1, para 1 who gave birth to a healthy 7-lb boy yesterday. She is very motivated to breastfeed him but is having nipple soreness. She also has to go back to school in 6 weeks to finish her semester and graduate from high school.
1. Use principles of evidence-based practice to help Christina with her sore nipples.
2. Investigate the best breast pumping methods to encourage Christina to continue providing breast milk when she returns to school.
3. What additional information might be helpful to gather to meet Christina’s needs using the template of evidence-based practice?
4. What professional activities can the nurse participate in to increase the utilization of evidence-based practice in her setting?

2-a-First, consider a regression where the independent variable is the neighborhood income around a school attendance zone and the dependent variable is student test scores. What is the likely sign of the coefficient on neighborhood income?
b-Now consider a regression where the independent variable is a measure of violent crime incidents around the school and the dependent variable is student test scores. What is the likely sign of the coefficient on violent crime?
c-Finally, consider a regression of violent crime incidents on area income levels. What is the likely sign of the coefficient on area income levels?
d-Now consider the sign of omitted variable bias in the first regression, neighborhood income levels on student test scores. What is the sign of omitted variable bias if we omit a measure of violent crime around a school? Explain.

1319 school children were evaluated at age 12 and at age 14 for the prevalence of severe colds. There were 356 children who had severe colds at age 12, and 468 who had severe colds at age 14. There were 212 children who had severe colds at both ages. Do school children tend to have more severe colds when they are younger?
