Typically they just take it in faith that the travel dates provided by the applicant are accurate. Moreover, in your case your interview was on April 24 and your oath is on May 31, slightly over a month later. Even if you had spent that entire month abroad, that would not be enough to create a problem with continuous residency. So I think it is rather unlikely that you'll face any detailed questions about that trip. Bring your passport and, if you have them, copies of your tickets/itinerary - but I rather doubt that you'll be asked for any info beyond the dates of the trip.
