Yes - when a survey is in 'published' state, an admin user is able to edit the following areas of it:

• Survey: Name, Description, Keywords and Category
• Add Questions: You have the ability to edit the text used in the questions and answers. You are also able to edit the number of answers, as well as the answer options, such as Sort Alphabetically, Shuffle Answers and Add Comment.
• Email: The subject, email type and body within the 'Email' tab are all editable.

Please note that if you have attached a survey to a policy, and choose to update that survey later, it will also update the version number of the policy to which it is attached.
