Glad you are asking lots of questions! I agree with eveyone's posts about washing your hands!!!!!!!
Also check out the CDC's new data on effectiveness of the liquid hand sanitizers. Their findings show these as more effective in reducing spread of microorganisms than handwashing in many cases. Expect to see them more and more in the clinical setting!
Review, remember, and PRACTICE your Basics of Infection Control. Standard Precautions apply to everyone, everywhere! Remember your links in the "chain of infection".
As for gowns, shoecovers, masks, all the time gloves -- that's going overboard in most cases. Think it through. Ask yourself, "Do I need a barrier here? Will I be touching with my hands (or clothing) any blood, body fluid, secretions, excretions, non-intact skin, mucous membranes or items contaminated with any of those substances?" If so, use a barrier.
A patient with C-dif who is not incontinent is treated like any other patient. We glove for specimen collection, gather and hold linens away from our body for EVERYONE!
Yes change your clothes when you get home. Keep ALL outside shoes away from children. Practice and teach your kids to practice good hygiene all the time.
Do your best to keep healthy too- eat right, sleep ( oh forget sleep, you're a nursing student:chuckle :chuckle ), and get your flu shot!
Mostly, make your decisions based on good science, not on panic.
Keep using your common sense, critical thinking skills!!!
.......And welcome to nursing too!! Best of luck to you in school.
