thought about that one a lot myself... i work for a herpetologist who has done gut content research on platyrhinos (but not extensively), and according to him they found mouse remains with some frequency....
i have seen pictures of a nasicus bite (the link is posted in this forum) and they show quite a lot of swelling... (if they are geniune, that is)
it makes sense to me that whatever form of venom they possess would also produce a swelling effect in a rodent with a smaller body size, perhaps causing the vital organs such as the heart and lungs to swell as well? or at least swell the body to the point of immobility? a snakes sense of smell is amazing as well, perhaps they are able to track a mouse after biting...
I have never witnessed feeding habits of platyrhinos though, so i can not be certain either way. I plan on doing some independant research this summer to get some credits towards my degree though, and have actually been considering looking into this... hehehe, let you know if i learn anything!!
