There are many types of elder abuse. Choose two types and discuss challenges you perceive in abolishing them. Justify why you consider them as the most crucial. Discuss how you can advocate and protect the elderly from abuse.
Hello Class,
I’d like to preface my post by saying that any act of abuse on the elderly is repugnant and deserves equal prevention and intervention. As someone who has personally had to make reports to charge nurses, managers, and Adult Protective Services, mistreatment of elderly patients is a serious problem for a vulnerable population. According to the National Council on Aging (NCOA):
Approximately 1 in 10 Americans aged 60+ have experienced some form of elder abuse. Some estimates range as high as 5 million elders who are abused each year. One study estimated that only 1 in 14 cases of abuse are reported to authorities (NCOA, 2019).
That being said, I’d have to say the most challenging abuse types to prevent or report are emotional and financial exploitation. Cultural factors, presence of cognitive illness, and susceptibility to these forms of abuse make interviewing difficult and can often be a grey area for reporting.
There are many ways to advocate and protect these patients from abuse, but being observant to cues like sudden financial changes, social isolation, depression, anxiety, and changes in psyche around certain family members or caregivers. Money management programs, helplines, local emergency shelter resources, and multidisciplinary teams that include social workers, APS, civil legal services, etc. can help to coordinate these older adults into a safe, healthy situation.

Nursung Leadership Introduction To The Planning Process
/in Uncategorized /by developerDiscussion: Introduction to the Planning Process
The nursing process provides a cornerstone for care. Engaging in assessment, diagnosis, planning, implementation, and evaluation helps to move the patient from his or her current state toward a desired outcome. How does this correlate with the strategic planning process?In this Discussion, you examine similarities and differences between the nursing process and strategic planning. You also consider why it is important for a nurse leader-manager to be familiar with the planning hierarchy and to apply business principles to promote strategic change at the organizational or systems level.To prepare:Review the information related to the nursing process and the strategic planning process addressed in Chapter 4 of the Sare and Ogilvie text and the other Learning Resources. Think about how the nursing process is similar to and different from the strategic planning process.Reflect on the value of nurse leader-managers’ contributions to strategic planning, as discussed by Dr. Huston in this week’s media.Using the Walden library, identify an example from the literature that demonstrates why it is beneficial for nurse leader-managers to be familiar with the planning hierarchy and why they should be engaged in strategic planning in addition to and in contrast with operational planning.
By Day 3
Post an explanation of how you view the similarities and differences between the nursing process and the strategic planning process. Share an example from the literature that demonstrates why it is beneficial for nurse leader-managers to be aware of the planning hierarchy and why they should be engaged in strategic planning in addition to and in contrast with operational planning.
Marquis, B. L., & Huston, C. J. (2017). Leadership roles and management functions in nursing: Theory and application (9th ed.). Philadelphia, PA: Lippincott, Williams & Wilkins.Chapter 7, “Operational Planning” (Note: You may have read this in a previous course.) This chapter describes the planning hierarchy and provides foundational information on strategic planning. As you read, think about distinctions between strategic and operational planning, as well as why a nurse leader-manager needs to be aware of and engaged in both.Sare, M. V., & Ogilvie, L. (2010). Strategic planning for nurses: Change management in health care. Sudbury, MA: Jones and Bartlett.“Introduction” (pp. xiii–xiv)Chapter 1, “Why Nursing Needs Strategic Planning: Professional Empowerment in the New Millennium” (pp. 3–16) Chapter 2, “The Healthcare Habitat: The Evolving Professional Home of Nursing” (pp. 17–40) Chapter 3, “The Business That We Find Ourselves In” (pp. 41–53) Chapter 4, “Just What Is Strategic Planning?” (pp. 57–82) Chapter 1 sets the context for why strategic planning is important for nurses and introduces key terms, while Chapter 2 addresses the evolving landscape of healthcare. Chapter 3 explores the merging of nursing care and business, as well as developments leading up to the current business model of care. Chapter 4 examines the nursing process and strategic planning.Carney, M. (2009). Enhancing the nurses’ role in healthcare delivery through strategic management: Recognizing its importance or not? Journal of Nursing Management, 17(6), 707–717.Retrieved from the Walden Library databases. The author examines the importance of strategic planning for nurse leader-managers and the extent to which nurses have adopted strategic planning into language and self-perception.
