Answer:
Praskovya Fedorovna's attitude to Ivan Ilyich's illness, as she expressed it both to others and to him, was that it was his own fault and was another of the annoyances he caused her.
Step-by-step explanation:
This is the line that shows that Praskovya Fedorovna does not think that she is responsible in the least for Ivan Ilych's illness. She seems to think that her husband is the only one who should be responsible for his illness. This is clear in the sentence above. The sentence tells us that Fedorovna thinks that the illness should not affect her, and that Ivan uses it to annoy her. We can tell that she is not very empathetic towards the needs of her husband.
