Highest risk for nurse is handeling chemotherapeutic agent itself from skin absorption in preparing, admixing and administering chemo drug. These days most hospital based chemo prepared by pharmacist under laminar flow hoods so nursing exposure greatly reduced.
Antineoplastic agents are excreted from the body through fluids such as sweat, vomitus, stool, and urine. Wearing gloves, eye shield when emptying urinal/bedbans, cover gown if patient incontient and care provided etc reduces exposure to almost nil from chemo. Sounds like you utilized proper precautions. Washing hands with good old fashioned soap and water decreases contact time of chemo agent with intact skin too--gel alcohol does provide enough of skin flush.
