Injured Toad, Help?

[AnimalLover93]

My stepdad was gardening recently and he accidently cut the toad with some garden sheers. Well I wouldn't say cut but either way a chunk of skin is missing near the head and you can see these white chunks. I assum that it might be the frogs bones or something but theres also some clear fluid where the chunk of skin hangs loosely. I'm worried, we're going to take the frog to a vet but we can't get him/her there until tomorrow after school around 12. Is there anything that I can do to make the frog more comfortable or at least clean him/her up? I've bathed her in water but I'm squeemish around wounds.
