R's BAD FALL

We have an intake vent for the heating/air in our hallway floor. It's large -- easily big enough for me and R to fit in together with some room to spare. Today, as we were cleaning, R removed the cover so she could swap out the filters, only we didn't have any new ones and she needed to measure for size. She went to the laundry room to retrieve the tape measure and while she was in there, she grabbed the load of clean laundry from the dryer to carry it to the bedroom in the back of the house. As she was walking back down the hall without the tape measure, she'd forgotten about the floor, and fell in about four feet down. I was outside and didn't see it happen, but I heard her screaming for my help from inside. When I came in, she was trying to pull herself out, hanging down into this hole, and the very heavy vent cover had toppled over on top of her head. When I saw her, I was scared to death. We managed to get her out of there and I replaced the cover before I fell in, too (which is totally something I'd do, being the clumsy person I am). R went to rinse off in the shower, as her leg was all torn up and bleeding and sore. I put a call into the doctors because I was worried about the fall and wanted to know what, if anything, we should do and what we should look out for. Dr. L (the other doctor in the practice) called us back and assured me that R would most likely be okay. He said to give her ibuprofen, make sure she kept her leg propped up, and to put ice on it. And he said to look out for any vaginal bleeding, which (knock wood) R hasn't had. She's been taking it easy and she pretty messed up. Her upper leg looks like hamburger meat, her arm is banged up and bruised, and she's complaining of a sore and swollen ankle. We're both taking tomorrow off and we'll get her leg and ankle checked out. Hopefully, we can go ahead and have our ultrasound with Dr. A one day early. I've been joking with R all day, saying how she'd go to extremes to get out of doing housework -- haha! Seriously, though, the whole event was scary and I'm praying that this mishap doesn't cause any setback for us. Wish us luck.
