As to the C/S report, luckily, most of the time the micro dept. will not read the follow up culture until the microbiologist comes in at 0900 in the am. So,,, you probably won't need to be faced with this one. Unfortunately, most new grads get put on nights when they have to begin to make decisions about when to call the doc. When in doubt, call. You can always go through your charge nurse or supervisor when you need a second opinion. But remember, the doc can't make a decision about information he doesn't have, so if something goes wrong, you will be the one with the problem.
