A nurse who discovers a nodule. swelling. or other abnormal finding during a scrotal examination should transilluminate the scrotum by darkening the room and shining a flashlight through the scrotum behind the mass. A scrotum filled with serous fluid transilluminates as a red glow; a more solid lesion. such as a hematoma or mass. doesnt transilluminate and may appear as a dark shadow.Option A: Although the nurse should notify the physician of the abnormal finding. performing transillumination first provides additional information.Options B and C: The nurse cant uncover more information about a scrotal mass by changing the clients position and repeating the examination or by performing a rectal examination.
