Yikes, blood!

I try to not be squimish around blood, but yikes. Last night around dinner time I was out picking up Hunter so he could help Brendan with one of his playstation games. (since B had to take it easy) When I got back, K said that B's leg started bleeding and the steristrip was starting to come off already. So nurse mom takes a look and oh my. The area is all bruising and it's starting to look nasty. Not as neat and clean as it looked while at the doctor's. I know it's normal but I call the doctor on call anyway. Will this dermabond hold up? I covered his leg with a gauze pad for overnight. We'll see how it looks this morning when he wakes up. I hope it's okay.
