Start with what you like. Do you have an area of nursing you want to go into? Like cardiac or psych or L&D? If so, look up articles on CINAHL (nursing research database, go to your school library website to get in) about racial, gender, socioeconomic or other disparities in that area. We have disparities all over healthcare, especially the US.
If you don't have a special interest yet, then pick something around a topic that is difficult for you, or a topic that you are studying in another class, a topic that you are about to be tested on, need to write a paper on, etc. I call this cross-studying. Learning about disparities in diabetes education, will help you understand diabetes better, even if that seems like a stretch. Learning about disparities in access to anti-hypertensive medication, will help you understand anti-hypertensive meds better, or at least help you remember the names of meds.
This is an important topic. Don't treat it like busy work. In fact, make every assignment the fullest learning opportunity you can make it.
