I would suggest that you reassure her that you are there for her when she has questions, or doesn’t understand. Keep it simple and move on to another subject.

Reassure your wife by giving her your full attention when she talks to you. Tell her that you are right there with her. Then, try to move onto something simple... make coffee, turn on nice music, flip through a magazine. or old family photographs. Redirect her attention to something less worrisome.

Thank you
