Here are the things that the NCLEX wants to make sure that you know about.
Identify the client according to facility/agency policy prior to administration of red blood cells/ blood products (e.g., prescription for administration, correct type, correct client, cross matching complete, consent obtained)
Check the client for appropriate venous access for red blood cell/blood product administration (e.g., correct gauge needle, integrity of access site)
Document necessary information on the administration of red blood cells/blood products
Administer blood products and evaluate client response
Saunders has a great section in the book about blood / blood products. Chapter 14, pages 158 – 168
A good overview –

And finally a great pdf that reviews blood types – actually from a ceu course so it is a bit in depth – https://lms.rn.com/getpdf.php/2091.pdf
