I am a third year external nursing student doing a subject called foundations of inquiry. My first assignment asks us to critique one nursing theory from section 4 of our study guide. The theories as such mentioned in the guide are: Activities of Daily Living; Self Care; and Epidemiology all written by different authors (theorists?). I emailed my lecturer only to become more confused, as I explained I am having trouble grasping some of the concepts and just wanted to know do I just critique one of those mentioned and he said he would make it easier and I could pick any nursing theory from any textbook and do a critique on it. I really just wanted to know if those ones listed were theories as such??? I think I am a little confused between models/theories etc etc. I am doing 3 other subjects this semester and currently have 3 extra adults and 5 extra children in my house (aswell as our 3) so am finding it hard to take in anything I read. It is my final sem of theory and I am terrified of failing, as I have completed 7 other assignments from the other subjects but feel I should of started this earlier as it is in depth and going over my head. Can anyone please help by maybe explaining the diff between theories/models etc? or someone might know of a theory that is easy for me to grasp and write about. Any help would be much appreciated.
