my patient was treated for MRSA on her nostrils 3 months ago.. she was already done with her antibiotics 2 mos ago.. i was accidentally pricked by an insulin needle because her arm jerked while i was pulling the needle out..it grazed my index finger and bled for 5 seconds. i washed it with warm running water and all. covered it with gauze and glove. she is not on contact precaution. how am i in terms of acquiring MRSA?
