You rarely find a nursing student who is working as a nursing position (PCT, Nurse assistant, etc). Generally, you have to wait till your second clinical is completed and have good grades. places near me hire people who have completed half their clinical rotations, and have top grades (one place requires a 3.4 minimum, other has no requirement). Plus you wont find a nursing job right when you start NS, and to be frank you shouldn't take a job in nursing if you don't have experience. With no medical background (real medical background of client contact and patient care) you may put a patient at risk for injury (if you do injure a patient you can be sued for assault, battery, or negligence!). And if you get charged with those, you can kiss your chance to get your RN license good-bye. As for the ICU, you probably won't find a position in one as a nursing student without being an EMT, ER technician, CNA or LPN, those units require someone with a background in emergency situations. Not to mention any time you spend in the ICU wouldnt be until your 3rd or 4th clinical, so that would have to wait. Most places ive worked at or looked at require a nursing student to know how to perform EKGs, identify arrhythmias, and preform phlebotomy, things you wont learn till the end of your Nursing Program (usually). Im sorry that you have bills and kids, but nursing school isnt a paying venture, it costs a lot, its competitive (very!), and many students spend about 90% of their spare time studying.
Nursing school doesn't pay you to do clinicals, in fact you pay them to do clinicals.
