Perhaps Ready could be at the end of the line:
kubectl get nodes | grep 'Ready$'
or almost at the end of the line, save for some whitespace:
kubectl get nodes | grep 'Ready[[:space:]]*$'
or perhaps the only thing in field 2:
kubectl get nodes | awk '$2 == "Ready"'

first one did not work.. second worked. ` kubectl get nodes | awk '$2 == "Ready"'`

I wasn't sure if the trailing space was from actual data or a formatting "typo". I've added a variation to the Answer to account for trailing spaces.
