CH Discussion:
What evidence-based information will you provide to Ms. Martin regarding her concerns of HRT? Discuss the advantages and risks associated with HRT.
Hormone replacement therapy (HRT) is the administration of synthetic estrogen and progesterone to replace depleting levels of hormones in menopausal women (Martin & Barbieri, 2018). HRT play an important role in the management of hot flashes, vaginal atrophy, and, the mood lability that many women experience during the menopausal transition. The most recent clinical practice guideline published by the Endocrine Society presents the approach HRT treatment is based on calculating a woman’s baseline cardiovascular and breast cancer risks before therapy starts. Like most other guidelines, the Endocrine Society suggests that HRT is only used for the management of menopausal symptoms, but not for the prevention of osteoporosis, dementia and/or cardiovascular disease. The optimum time to start hormone replacement therapy is before 60 years of age or within the first 10 years after menopause. Use the lowest possible dosage of HRT for the shortest possible time to achieve symptom alleviation. HRT includes estrogen therapy alone and combined estrogen and progestin therapy. Estrogen therapy alone is reserved for patients who does not have uterus and combine estrogen progestin therapy for women who has a uterus. The benefits of HRT in menopausal women are to relieve vasomotor symptoms of hot flashes, night sweat, vaginal dryness, to reduce urogenital symptoms such as urinary frequency, dyspareunia and urgency, to prevent bone loss and to reduce the risk of colon cancer (Fait, 2019). The risks of HRT include weight gain, endometrial hyperplasia, endometrial cancer, ovarian cancer breast cancer, heart attack, stroke, DVT, and gallbladder diseases (Fait,2019).
What are your recommendations for Ms. Martin? Will you recommend continuing or discontinuing HRT and why?
The use of HRT should be a personalized decision with discussion regarding the balance of potential risks and benefits as individualized to that woman’s health circumstances (Newsome, 2016). I would perform a thorough history in physical especially a gynecological and sexual history and take into consideration the important factors including her age, health history, family medical history, type and timing of menopause, impact of symptoms on quality of life, and her personal preferences. I would provide Ms. Martin all available up to date evidence-based information regarding HRT including the benefits, risks, contraindication, of continuing, lowering, tapering and/or discontinuing the therapy. I would also counsel her in detail alternative nonhormonal options including lifestyle modifications, herbal supplements, mind-body techniques, and nonhormonal prescriptions. I would work and weigh the possible risks and benefits with her to find the best realistic plan for her based on the clinical findings and her individual needs.
What alternative treatments for menopausal symptoms will you discuss with Ms. Martin?
· Pharmacological therapy:

Low doses of antidepressant SSRIs for mood swings and depression (Newsome, 2016).
For vaginal dryness: Low-dose vaginal estrogen cream, tablet, or ring which are absorbed very small into the bloodstream, so the chance of health problems is much lower than with estrogen pills.
Water- or silicone-based vaginal lubricants before sex to reduce discomfort.

· Non-pharmacological therapy: exercising daily, increasing fluid intake, dinking cool drinks, avoiding spicy food, coffee and alcohol, plenty of sleep, and stress management such as relaxation, breathing techniques, yoga, and tai chi (Newsome, 2016).
Discuss the recommended screening tests, using the latest evidence based guidelines that Ms. Martin should have.
Ms. Martin’s last mammogram was 2 years ago, and last pap-smear was 5 years ago. Based on the latest evidence guidelines of the American College of Obstetricians and Gynecologists, she should have cervical cytology, mammography, diabetes, lipid profile, TSH, colonoscopy, bone mineral density and genetic testing. Also, she should be screened for nutrition, abuse/neglect, sexual practices, STD s, tuberculosis skin testing and urinary and fecal incontinence (The American College of Obstetricians and Gynecologist, 2017).
What health promotion, maintenance, and prevention education would be important to provide to Ms. Martin?
The importance education I would provide to Ms. Martin:

Nutrition—Eating a healthy balanced diet with adequate calcium and vitamin D help maintain to help her stay healthy and strong bones (The American College of Obstetricians and Gynecologist, 2017)
Exercise—regular exercise decreases bone loss and improves wellbeing. Weight-bearing exercise, such as walking, exercise band, or handheld weights can help strengthens muscles and keep bones strong. With her age, balance training such as yoga and Tai chi is highly recommended to avoid fall which may lead to broken bones.
Routine health care— includes annual physical exam, test, well women exam, dental checkups and eye exams. Routine health care visits can help detect problems early and prevent further chronic and complicated disease (ACOG, 2017).

Magazine article on elder abuse- needs polished.

This project for this course is the creation of a magazine article on Elder Abuse….  There’s no word count or page number requirements. Just everything needs to be addressed,
From policy to culture to economics, the family structure in America and across the globe is consistently in the middle of debate and discourse. Questions are routinely asked around what family means, why the definition keeps changing, and who defines “family.” Sociologists use sociological theories and perspectives to study these questions and inform their future studies, policies, and social strategies. Studying the construct and the data picture of families can also be beneficial to both personal and professional lives, aiding individuals in group and interpersonal relationships.
In this final project, you will write an article for a parenting magazine about a familial trend affecting a population. You will base your article on the analysis of the specific trend and its influences, impacts, and presence in diverse cultures using key sociological perspectives. You will then discuss the value of sociological theories and perspectives in approaching social problems. In concluding the article, you will propose an evidence-based response for minimizing the potential negative impacts of the trend.
 
I AM ATTACHING ALL THE CRITICAL ELEMENTS AND THE MILESTONE PAPERS THAT YOU WILL NEED TO MAKE THIS MAGAIZNE ATRICTLE A SUCCESS. ALL THE RESEARCH IS ALREADY DONE FOR THIS ARTICLE ALL YOU GOT TO DO IS POLISH IT UP WITH FACTS AND CRITICAL ELEMENTS  NOW INTO A MAGAZINE ARTICLE.
 
 
A. Explain the familial trend you selected and provide an overview of its specific influences on the family dynamics.
B. Provide historical context for your familial trend. How has this trend progressed historically in the United States? What used to be the norm?
II. Comparative Perspectives: In this section you will begin by looking at the familial trend on a global scale. You will then narrow your focus to the United
States, examining the influences on the trend, the impact of the trend on society, and how the trend manifests itself within diverse cultures in the
United States.
A. Select a country outside the United States and describe the norm in this country around your previously selected familial trend. ATTACHED IT WAS CHINA.
B. Compare the presence of your selected familial trend in the United States to the presence in the other country. Is this specific trend present in the other country? Substantiate your determinations with research.
1. If the trend is present, how is the presence similar to or different from how it manifests itself in the United States, and why do you think these similarities and differences exist?
2. If the trend is not present in the other country, why do you think it is not?
C. Looking at the issue inside the United States, identify the relevant social variables and disparities influencing this familial trend and explain how they influence this trend.
D. Explain how the familial trend negatively impacts modern families, providing specific examples and substantiating your response with resources.
E. Explain the influence of the familial trend on other social institutions, providing specific examples and substantiating your response with resources. For example, specifically how does the trend influence education, employment, or healthcare?
F. Compare the presence of this familial trend between cultures in the United States. Substantiate your determinations with research. How does the trend manifest itself similarly or differently in different cultures? Is the trend as present in some cultures as it is in others?
III. Sociological Analysis: You will now analyze your chosen familial trend, using the three relevant sociological perspectives: conflict perspective, functionalism perspective, and symbolic interactionism perspective.
A. Apply the conflict perspective to explain why the familial trend affects families differently. Apply this perspective specifically to your previous comparisons to explain any differences in how the trend affects cultures. If there were not any differences, use the perspective to explain generally why different families have different experiences.
B. Apply the functionalist perspective to explain the benefit of the familial trend on society. How does the familial trend influence the family dynamic and therefore positively influence other social institutions and society as a whole?
C. Apply the symbolic interactionist perspective to analyze how families define their meaning and how this definition changes. How does symbolic interactionist theory explain the ways that families define themselves and how this definition evolves?
IV. Value of Sociology
A. Identify personal and societal biases and assumptions around the familial trend. What are your personal biases and preconceived notions based on your life experiences? What are some societal biases and assumptions that the audience might have around the trend?
B. Explain to the audience how using sociological theories and perspectives to analyze the familial trend can help limit biases and challenge assumptions. Provide a specific example related to your analysis of the trend.
C. Explain to the audience the value of sociological theories and perspectives when addressing real-world familial problems. How can the use of these theories and perspectives help address familial problems faced in personal and professional lives?
V. Evidence-Based Response
A. Describe attempted responses that have been successful in addressing negative impact(s) of the specific familial trend and identify some best practices based on the successes.
B. Based on your research, propose a response to address negative impact(s) of the familial trend.
C. Explain why your proposed response is likely to be successful, substantiating your explanation with research. In other words, explain how the response takes into account your previous research of attempted responses, identified best practices, and influences and impacts of the trend.

Phase 4: Action Plan and Financial Implications
Table of Contents
Development of an Action Plan
At this juncture in the planning process, you have not only identified a need and defined the desired outcome for your project, but you have also assessed the various internal and external factors which influence the problem. All of this information will play an important role as you develop a plan of action to facilitate change.
Strategic Interventions to Facilitate Outcome Achievement
Much like a nursing care plan, a plan to guide change includes a detailed work schedule of activities, tasks, and interventions which are all designed to facilitate achievement of the stated outcome. These activities, tasks, and interventions can be referred to as an action plan, and will also include target dates for completion.
Clear Communication
The purpose of an action plan is to clarify for you (the project leader), your faculty or mentor and any other pertinent stakeholders, the specific plan of activities, tasks, and interventions which will be implemented, and when they are targeted to take place. If more than one person is involved in the implementation, the action plan can also serve as a communication tool to keep everyone on the same page, and may even denote ‘who’ is responsible for doing ‘what’, and ‘when’ those activities will be carried out.
Outputs and Deliverables
Within your action plan, you may have outputs or deliverables which are a necessary element in your planned change project (for example, the development of a new policy, staff education program, or teaching tool). You will include these outputs or deliverables within the action plan, as well as a date by which they should be attained or completed. Like other activities or interventions, outputs serve to facilitate achievement of the overarching project outcome. For example, a revised policy on catheter care and mandatory staff in-service sessions may facilitate achievement of an outcome geared toward the reduction of CAUTI on a particular unit.
Essential Resources
As you develop your action plan, consider the resources which will be necessary to actualize the plan. These may be human resources, financial resources, and/or material resources. Making note of the necessary resources will inform the project budget.
Helpful Reminders
As you develop an action plan, consider the following:

What steps need to be taken to facilitate outcome achievement?
What are the target dates for action steps, and who is responsible?
What stakeholders need to be engaged in the process, and how will that engagement take place?
What resources will be needed (human, financial, material)?
How will these resources be secured and what expenses will be involved?
Are there any special steps needed to assure that the necessary resources are available for use?
Are there specific outputs that will be needed to facilitate the achievement of the overarching project outcome (such as a new policy or other deliverable)?
If so, are they clearly incorporated into the action plan?

Consideration of Financial Resources
Managing fiscal resources is critical for efficient operations at the unit or organizational level. MSN-prepared nurse leaders are involved in managing the financial aspect of planned change projects that may involve stakeholders and resources both internal and external to the organization. Understanding the relationships between available resources, revenue, and expenses can influence efficiency of a project, and its future sustainability.
Just as with any personal budget that you might use, budgeting for planned change initiatives requires intentional planning. The advanced practice nurse must gather information in order to construct a solid budgetary plan to project the expenses that will occur.
Identifying Resources and Projecting Cost
Budgeting for the project is important as you plan for action steps and interventions. To initiate the process of budgeting for a planned change project it is important to forecast or project the expenses that will be involved. This will require you to:

Identify the resources necessary to implement the planned change project

Financial resources
Material resources
Human resources

Project or ‘forecast’ the expense or cost for the necessary resources

Identifying Sources of Funding
As you prepare a budget for the project, consider the funding sources available. Who will pay for the necessary resources to carry out the initiative? Will costs be absorbed by the organization? Are donations of resources a possibility? Will it be necessary to reallocate funds from other revenue streams to cover the project expenses?
Addressing Variance within Budgeted and Actual Expenses
Once the planned change project is underway, the advanced practice nurse will be responsible for managing the cost of the initiative. To facilitate this process, the nurse will note the actual expenses incurred for the necessary resources. When the actual cost differs from the projected cost, a variance occurs. Any variance that occurs between the projected and actual budget must be analyzed. As revenue and expenses deviate from the projected numbers, adjustments in the budget may be required.
Think About It
While the budgeting process may seem straightforward in terms of forecasting expenses and revenue, an effective budgeting process requires the nurse leader to anticipate and address variables that impact the budget in unexpected ways. As you forecast a budget for the planned change project, consider the following:

What human, financial, and material resources are needed for your project?
What expenses are associated with the required resources?
What variables might impact the cost of the project resources?
Should a variance occur, how might you address the situation?
In what ways might a cost-benefit analysis demonstrate the long-term value of your planned change project?

Practicum Application and Activities
To be effective, an action plan should specify the activities and interventions that will be carried out in order to facilitate achievement of the project outcome. Also included on the action plan are target dates for implementation, along with a designation of the person(s) responsible.
Budgeting for the planned change project is necessary for efficient use of resources. In the early phases of any project, it is important to forecast or project the expenses necessary to carry out the action plan. During implementation, careful monitoring of actual expenses can help the nurse leader to identify and address variance that may occur.
Review the Johns Hopkins Appendix I located in the MSN Toolbox area of the course. Proceed with the following activities. Document your practicum-related activities on the Practicum Log:

Prepare a plan with specific talking points to meet with your faculty (and practicum mentor if available) regarding an action plan and financial considerations for the planned change project. Think about how each activity and intervention can facilitate achievement of the project outcome.
Meet with your faculty (and practicum mentor if available) to discuss the action plan and financial considerations for the planned change project.
As the opportunity allows, identify, communicate, and collaborate with stakeholders impacted by plan of action.
Complete the Johns Hopkins Appendix I document.
Validate your work on Phase 4 with your faculty (and practicum mentor if available) as needed.
Revise your work as necessary.
Submit the Johns Hopkins Appendix I completed with your time log, once Phase 4 completed.

Lipitor is a drug used to control cholesterol. in clinical trials of

[1] Lipitor is a drug used to control cholesterol. In clinical trials of Lipitor, 94 subjects were treated with Lipitor and 270 subjects were given a placebo. Among those who were treated with Lipitor, 7 developed infections. Among those given a placebo, 27 developed infections. Use a 0.05 significance level to test the claim that the rate of infections was the same for those treated with Lipitor and those given a placebo.[2] Simple random samples of high-interest (5.36%) mortgages and low-interest (3.77%) mortgage were obtained. For the 40 high-interest mortgages, the borrowers had a mean FICO credit score of 594.8 and standard deviation of 12.2. For the 40 low-interest mortgages, the borrowers had a mean FICO credit score of 785.2 and standard deviation of 16.3.a) Use a 0.01 significance level to test the claim that the mean FICO score of borrowers with high-interest mortgage is lower than the mean FICO score of borrowers with low-interest mortgage.b) Does the FICO credit rating score appear to affect mortgage payments? If so, how?
The test of interest here is,
As here the sample size for both the samples are large enough so we can assume the normality using CLT and thus a Z-test would be appropriate. And the hypotheses also show that it’s a left tail test.The output is given below,
Here the lower p-value suggests that we should reject the null hypothesis and conclude that the mean FICO score of borrowers with high-interest mortgage is lower than the mean FICO score of borrowers with low-interest mortgage.
Note that the above analysis showed that the interest rate is higher for the group with lower FICO scores. Thus the FICO credit rating scores appear to affect mortgage payments. If the FICO score is high then the interest rate is expected to be low so the mortgage payments would be low. And for low FICO score the opposite is expected to be observed.[3] A random sample of the birth weights of 186 babies has a mean of 3103g and a standard deviation of 696g (based on data from “Cognitive Outcomes of Preschool Children with Prenatal Cocaine Exposure,” by Singer et al., Journal of the American Medical Association, Vol. 291, No. 20). These babies were born to mothers who did not use cocaine during their pregnancies. Further, a random sample of the birth weights of 190 babies born to mothers who used cocaine during their pregnancies has a mean of 2700g and a standard deviation of 645g.a) The birth weights of babies are known normally distributed. Use a 0.05 significance level to test the claim that both samples are from populations having the same standard deviation.b) Using your finding in (a), construct a 95% confidence interval estimate of the difference between the mean birth weight of a baby born to mothers who did not use cocaine and that of a baby born to mothers who used cocaine during their pregnancies.c) Using your finding in (b), does cocaine use appear to affect the birth weight of a baby? Substantiate you conclusion.
a) Here we need to test for the equality of the standard deviation (same as variance) so the hypotheses of interest are,
As this is two sample test for standard deviation or variance so the test can be performed using a F test. The obtained output is given below.-value is larger than the significance level so we are failing to reject the null hypothesis and concluding that the data does not suggest that both samples are from populations having different standard deviation.b) Here we found out that the variations are not different in two groups so we should use a pooled variance t-test.
From the values from above table,95% confidence interval for difference =
c) From the above calculated confidence interval we can see that the confidence interval does not contain the value 0. So based on the findings we can conclude that cocaine use appears to affect the birth weight of a baby.[4] A large discount chain compares the performance if its credit managers in Ohio and Illinois by comparing the mean dollars amounts owed by customers with delinquent charge accounts in these two states. Here a small mean dollar amount owed is desirable because it indicates that bad credit risks are not being extended large amounts of credit. Two independent, random samples of delinquent accounts are selected from the populations of delinquent accounts in Ohio and Illinois, respectively. The first sample, which consists of 15 randomly selected delinquent accounts in Ohio, givens a mean dollar amount of $524 with a standard deviation of $38. The second sample, which consists of 20 randomly selected delinquent accounts in Illinois, gives a mean dollar amount of $473 with a standard deviation of $22.a) Assuming that the normality assumption, test to determine if the population variances are equal with ? =0.05.Here we need to test for the equality of the variance so the hypotheses of interest are,
As this is two sample test for variance and normality assumption is valid so the test can be performed using a F test. The obtained output is given below.F Test for Differences in Two Variances

b) Test with ? =0.05whether there is a difference between the population mean dollar amounts owed by consumers with delinquent charge accounts in Ohio and Illinois.Here the population variances are not equal so we should run a separate variance t test. The results are as follows,Separate-Variances t Test for the Difference Between Two Means(assumes unequal population variances)DataHypothesized Difference0Level of Significance0.05Population 1 Sample Sample Size15Sample Mean524Sample Standard Deviation38.0000Population 2 Sample Sample Size20Sample Mean473Sample Standard Deviation22.0000

Here based on the result we are rejecting the null hypothesis and thus the conclusion is based in the data there is a difference between the population mean dollar amounts owed by consumers with delinquent charge accounts in Ohio and Illinois at 0.05 significance level.
c) Assuming that the normality assumption and the condition you checked in a) hold, calculate a 95 percent confidence interval for the difference between the mean dollar amounts owed in Ohio and Illinois. Based on this interval, do you think that these mean dollar amounts differ in a practically important way?
Here the 95% confidence interval is =
As we can see the computed confidence interval has values not so high as lowest is 28.10 so based on this interval, I don’t think that these mean dollar amounts differ in a practically important way.

History of americas quiz 3

Question 1
The Monroe Doctrine stipulates:
  America for the Americans, no further European intervention unless is done in existing European colonies in the Americas.
  A part of US Foreign policy under the Good Neighbor policy. 
  Teddy Roosevelt’s idea of American Imperialism 
  Commercial trade doctrine between the United States, Great Britain, and Latin America.
Question 2
The Corollary to the Monroe Doctrine, or Roosevelt’s Corollary, represents an expansion of the Monroe Doctrine.  The corollary stated:
  “…that not only were the nations of the Western Hemisphere not open to colonization by European powers, but that the United States had the responsibility to preserve order and protect life and property in those countries, and thus justifying US intervention in the region.”
  “…it represents an addendum to the Monroe Doctrine added in 1905.” 
  “…favors European intervention in the Western Hemisphere.” 
  “…nations in the Western Hemisphere are to engage in trade exclusively with the United States.”
Question 3
The Dirty War was a period of state sponsored terrorism present in the 1970s in Latin America.  This state terrorism had one objective in mind:
  The eradication of political dissidence. 
  A general support to leftist movements by authorities. 
  Incorporate urban and rural leftist guerrilla movements to mainstream society.
  Provide military training to dissident groups. 
Question 4
During the Progressive Era, working woman – immigrant and native, working class and professional – became a symbol of female emancipation. In her influential book Women and Economics, Charlotte Perkins Gilman wrote that a growing number of younger women desired a lifelong career. What was Perkins Gillman’s main argument?
  Women were fulfilled with their assigned role of “house service.” 
  Women experienced not fulfillment but oppression, and the housewife was an unproductive parasite, little more than a servant to her husband and children.
  Women were satisfied with the prevailing gender norms. 
  The prevailing gender norms made women capable of contributing to society and enjoy freedom.
Question 5
According to lecture, one of the reasons that led to the Revolution in Mexico in 1910 was:
  The inclusion of the Mexican middle class in the political process. 
  Concessions made by the Porfirian elite to the middle class in Mexico. 
  An alliance forged between the middle class and the Mexican elite. 
  Politics of exclusion. 
Question 6
Formed in 1905, the Industrial Workers of the World (IWW) sought to mobilize the immigrant factory labor force, migrant timber and agricultural workers, women, blacks, and even the despised Chinese. In addition to organizing labor in an intersectional fashion, what other factor attracted the attention to the IWW?
  Their battle for freedom of speech. 
  Their songs denouncing unfair labor practices. 
  Their alliance with big business. 
  Their support of skilled industrial and craft laborers, nearly all of them white.
Question 7
During the Progressive Era, Carlos Montezuma became an outspoken critic of federal Indian policy. What is Montezuma’s main argument in his article “What Indians Must Do,” published in the Society of American Indians?

  Costa Rica 
  Colombia 
  Mexico 
  Chile 
Question 9

Question 11
In the study of people across time, professionals often times employ a periodic approach over a thematic approach. In studying history by periods, we get a false sense of terminality. The alternative to this false sense of terminality is the thematic approach of changes and continuities. What is the advantage of studying history through the theme of changes and continuities?
  The theme of changes and continuities makes history easier to understand, since time is treated in a linear fashion, not in a circular manner.
  By studying history in a thematic approach, we get a better sense of how people fare across time and get a better sense of what conditions have really changed, or if exploitative conditions continue to be the same as in the past.
  Thematic approach gives historians a better understanding on how to prevent making the same mistakes from the past.
  Thematic approach allows historians to better predict the future.

  Guerrilla Warfare. 
  The Communist Manifesto. 
  Prairie Fire. 
  Das Kapital. 
Question 15

  Integration. 
  Segregation. 
  Separate but equal doctrine. 
  Equal protection test. 
Question 20
The Harlem Hellfighters and the Tuskegee Red-Tail Angels are two prime examples of not only the contradictions of being an American, but also of blatant racial segregation. Regarded as one of the worst decisions in U. S. Supreme Court history, it established the separate but equal doctrine.
