I want to go to college for nursing. but when i went to a cadaver lab for A&P class, i couldnt look.?

i want to be an RN, prefereably a pediatric nurse. do you have to dissect cadavers? they had me sit down when i went two weeks ago with my high school A&P class. i felt really light headed liike i was going to pass out. so i just didnt look at any of the body parts or organs. help?
