It is possible to ask a repeat group of questions for each selected answer from a select_multiple question. And you can reference each answer inside the matching repeat to guide the respondent. You need to use the current repeat position to identify which answer you want to pull from the earlier question. The repeat position counting starts with 1 but the answer counting starts with 0, so you need to subtract 1 from the position number to get them to align. The following calculation will get you the name of the matching selected answer from the previous question:
selected-at(${intervention},position(..)-1)
For readability we want the label of the relevant answer, so we need to expand the above to the following:
jr:choice-name(selected-at(${intervention},position(..)-1),'${intervention}')
After pulling a label using the above in a calculate type question, we can then use it in our question prompt inside the repeat. See repeat_loop.xlsx (10.7 KB) or below.

Please make sure you read the Tip in the documentation on Repeating Questions:
Using repetition in a form is very powerful but can also make training and data analysis more time-consuming. Repeats exported from Central or Briefcase will be in their own files and will need to be joined with their parent records for analysis.
Before adding repeats to your form, ...
You will want to test your form and the data export. Make sure you understand how using repeats will affect your data output!
