Why would this design be the most appropriate for answering the research questions? Conversely, why would quantitative method design not be appropriate?

High turnover rates among nurses in nursing homes and what can be done to lower these high rates. Qualitative Research Plan.I have attached paper that is Quantitative Research Plan. This one is just like that one but must be the Qualitative approach. (The same topic as paper attached.)
Outline:
qualitative research plan you should include:

An introduction.
A purpose statement.
Viable research question(s).
A written research plan that addresses the following questions:

What are your research questions? To what extent can you test them? How would you justify the viability of your questions?
Why would this design be the most appropriate for answering the research questions? Conversely, why would quantitative method design not be appropriate?
What approach would you select for this study (ethnography, grounded theory, case study, phenomenology, narrative)? Why is that approach the most appropriate one for answering the research questions?
What would be your role as the researcher?
What is your target population? How would you identify and recruit participants? What factors would contribute to determining appropriate sample size? (You do not need to calculate sample size for the assignment).
What instruments might you use, if appropriate for your plan?
What data collection procedures might you use? Why would those be the most appropriate methods to use? How would that data help answer your research question(s)?
How would you ensure quality and reliability of data?
What are threats to validity? How might you mitigate them?
What are the ethical considerations related to your plan?
