Final answer:
The only 'dirty' trash mentioned is a big cardboard box containing a fancy dress that needs mending. The nurse brings it out and places it on a table.
Step-by-step explanation:
In the given text, the only "dirty" trash that the nurse brings out of the house appears to be a big cardboard box which contains a fancy dress in need of mending. The interaction occurs in a play where Nora, a character, is seemingly frustrated with the condition of the dress and consequently contemplates destroying it. The nurse, however, suggests that it can be repaired with some patience. This box with the fancy dress is stored briefly on the table as the nurse brings it out for Nora to inspect.
