If you're 8 months, you might as well wait until you've had your baby and finished your maternity leave. Someone's not going to hire you only to not have you not be able to work for at least a month or two after you are hired.
As far as safety goes, I have a two year old and six month old and they're both fine. Don't take the implants while you're pregnant or nursing. Don't hang chemo. As for handling body fluids, use common sense. Gown and glove. If someone's grossly incontinent, change patients. Not for one of their walkie-talkies either. Not all the patients are receiving chemo or have implants. Making a switch shouldn't be to complicated. Many of them are admitted for complications after they have received their chemo outpatient. The chemo is usually out of their systems by then, but the side effects need treated.
For the most part I felt better off on the Onc floor. Because of having neutrapenic patients, we don't get the gross isolations. No shingles, chicken pox, flu, r/o TB, etc. Also, we usually only take isolation patients that are our own. That usually cuts way down. The worst we usually have are a few c-diff's b/c of all the abx these poor people wind-up taking and the occasional MRSA. Follow standard precautions and you'll be fine. The only thing I avoided like the plague was when one of our pt's had CMV in her gut and peritoneal cavity. I didn't clean-up her BM. Another nurse and I swapped Bedside Commode duties when I had her. She used to yell at me for even coming in her room. RIP, Lillian . . . .
