Resistant bacteria are extremely commonplace in a hospital, to the point that I think a lot of the testing we do is ludicrous. We swab every patient's nose to test for MRSA and yet never bother to test the hospital workers. Absolutely pointless.
Nurse: "The patient in 439 is MRSA positive on nasal swab."
Nurse: "Do we need to do anything about it?"
Me: "Yes. I want you to swab your nose and send it for testing. If it comes back positive take off work and request disability pay."
