Word parts
What it means
In imaging, X-rays and CT scans use small doses of radiation to see inside the body. In cancer care, radiation therapy uses high doses aimed at a tumor to kill cancer cells. Radiation can come from a machine outside the body or from a radioactive source placed inside (brachytherapy). In pain assessment, radiation means pain that spreads, such as chest pain that radiates to the left arm or jaw.
For the nurse
Skin under external radiation can become red and sore: teach washing with mild soap and lukewarm water, no lotions or powders on the area unless approved, loose clothing and no sun. For an internal implant, limit time near the client, keep distance and use shielding, and keep pregnant visitors and staff away.
In a chart
"Client reports crushing chest pain radiating to the left arm."
