dont let the colostomy scare you. my boyfriend has one and he worries his self to death that i might see it! they are really easy to care for. irriagtion is just flushing the bag clean after you empty it. You need to remember that your patient knows that you are a student and learning. they dont expect you to know everything, just dont use them as a guinea pig. if you tell them regardless of what comes up if you dont know how to do something you will find someone who does they will have all kinds of respect for you and will help you all they can.
