When you are looking at an approval request, the form has a context-appropriate summary of the item to be approved.

Important: Classic approval rules have been replaced by the Workflow Studio Ask for Approval action. Use Workflow Studio to create workflow-driven approval logic that is easier to maintain and provides better reporting information.

For example, if you're looking at a Change Management approval request, you will see details from the relevant change request. For a Service Catalog approval request, you will get details of the request.
