Liz, I don't know your circumstances so only you can decide, but I would like to caution you against automatically turning down a PT position just because it may not cover all of your bills on its own.
In today's economy, you may find it difficult to find a FT position right away. One option is to accept the PT job, and then take a second job that is PRN, NOT PT. Another PT position will have scheduling issues like onaclearday pointed out, but as PRN you can work when it fits into your PT schedule. I worked 2 jobs this way for 18 months until a FT job became available.
Also consider that someone seeking a job almost always looks more attractive to a potential employer when they are already actively employed, so it could work to your advantage to have a PT job even if you continue to look for other employment. And if you have any inclination that it might take awhile to find a FT job, having some money coming in from a PT job is better than nothing at all, even if it doesn't cover all of your bills.
Just some things to think about.
Some PRN positions also have requirements about when and how much you work. for instance, you might have to work a major holiday every year plus 1 weekend a month, or something like that.
You'll be fine, just get the benefits and all agreements and rules in writing, along with your salary, shift, and start date agreement.
