Do I have these two questions written correctly?

Dr. Anton's nurse applied hydrogen peroxide, Neosporin, and a bandage to the new patient's wound.

The serial 7s revealed, in my opinion, evidence of abnormalities.

They both look right.

Thank you. I did find the 7s needs to be 7's :-)

Yes, both of your questions are written correctly grammatically. However, it seems like you may want to clarify the purpose of the questions or provide more context in order to receive a more specific answer.
