How to prevent pain and bruising when administering subcutaneous heparin injections?

I am writing a paper that is about the question stated above. one of the files i uploading including the rubric for the paper itself. it is to be a minimum of 8-9 paragraphs and then references, all in APA style. my approved quantitative research article I chose is uploaded and called Comparison of 3 methods to prevent pain and bruising after subq heparin administration (uploaded for references). The rest of the articles uploaded are just other reference articles that you could use throughout the paper that i found. The book that we are using is called Understanding Nursing Research: building an evidence-based practice by: Susan K. Grove. Also the last file i uploaded is the PICO worksheet which explains itself and has to have a question in the opening paragraph of the paper. No set page requirements just need at least 8 paragraphs including everything that is stated in the rubric that i uploaded.
