I've had it happen to me, and as described above, it was an older (50s) man, obviously blue-collar, and apparently worried about his condition.
Also, I've been taught that non-sterile gloves are for PERSONAL protection, not for protecting the patient, unless of course, the wearer has open cuts/sores. non-sterile is just that, they can still carry pathogens on the outside and infect the patient, tho this is unlikely if precautions are used.
It often amazes me some of the mis-information or misunderstanding even on this board. I'm glad we try to educate the public, but we also must strive as nurses or future nurses to educate ourselves to the best of our abilities!
