I withdrew from Med surg last semester and I am now retaking it in the fall of this year. If there is anyone out there that did very well in Med surg , please can you offer some assistance . The University that I attend have only one med surg class which is a five credit class. The first test is normally acid base balance , respiratory and fluid and electrolyte content . Can anyone offer any suggestions are books that can give a better understanding of med surg etc. Any help will be greatly appreciated.
