yeah, you mainly have the "general education" sciences out of the way before you hit clinicals- like biology, anatomy and physiology, pathophysiology and chemistry... I've been in clinicals for 2 semesters now, so I am actually in the hospital working with patients! It's definately tough, they expect us to know SOOOOO much!
My test tomorrow is on fluid & electrolytes- so I have to know the signs/symptoms, causes, treatments, & nursing interventions of the highs AND lows of sodium, potassium, calcium, magnesium, phosphate, and chloride. Also, respiratory acidosis and alkalosis and metabolic acidosis and alkalosis. And a ton more. It's also on Diabetes, Type 1 & 2... So we have to know all the causes, signs & symptoms of those and hypo- and hyperglycemia as well as how to treat it and what nurses can do. AND the test is also on peri-operative care, which is pre surgery, during surgery and post surgery, so we have to know complications, anesthesia, etc... UGH! not fun... it all jumbles together and my brain is mush right now! haha
