Case Study, Chapter 8, Unlicensed Assistive Personnel and the Registered Nurse 

The increased use of unlicensed assistive personnel presents both opportunities and challenges for the American health care system. The nurse manager has to deal with the challenge that unlicensed assistive personnel only be used to provide personal care needs or nursing tasks that do not require the skill and judgment of the RN.

1. The nurse manager reviews the national effort to define the scope of practice for unlicensed assistive personnel. In 2007, the American Nurses Association made recommendations for a national and/or state policy for nursing assistive personnel. What are the six actions that should be taken to create a national and/or state policy agenda about the educational preparation of unlicensed assistive personnel and the competencies they should have for safe practice?

2. The need in health care today is for today’s nurses to have highly developed delegation skills in working effectively and efficiently with unlicensed assistive personnel. This is critical to ensure the clients’ needs are met and their safety is not jeopardized. What are the key general principles that the nurse manager needs to review with professional registered nurses in delegating to unlicensed assistive personnel?

Question Description

For this project assignment, you will develop a business report that covers some real estate investment options for John and Becky Warbucks. The couple just inherited $200,000. They are looking to invest a portion of the money in some type of real estate investment. They already own a home that is worth $250,000 with a mortgage balance of $175,000. The report should give the Warbucks enough information to make a decision based on the information that you provided on real estate investments. Your report should include:

  • Descriptions and examples of different types of real estate investments.
  • Advantages and disadvantages of each type of real estate investment.
  • A discussion of how John and Becky can use real estate to generate income.
  • Given their current situation in the real estate investment (i.e., home ownership), what you would recommend they do with the portfolio and explain why.

Be sure to write with audience-specific language and professional tone. It should be written for clients who are unfamiliar with real estate rather than for an investment or real estate professional. Offer supporting evidence and include a reference list. Your report should be clearly organized and written in a business report format. A reference list, proper grammar and punctuation are required.
