The \currentconstructionnumber command contains the name of the counter
but getting the counter value won’t help because it comes too late.

The referenceprefix key is only usefull when you set the reference by hand.

When you always all three elements (question, hint and answer) you can
increment
a counter at the begin of each element and create a page reference which
contains
the value of the counter.
Below is a modified version of my previous example for this method.
%%%% begin example
\setupinteraction[state=start]
\define[1]\QuestionTextCommand
{\doglobal\increment\QuestionCounter
\pagereference[question:\QuestionCounter]%
\doifreferencefoundelse{answer:\QuestionCounter}
{\goto{#1}[answer:\QuestionCounter]}
{#1}}
\define[1]\AnswerTextCommand
{\doglobal\increment\AnswerCounter
\pagereference[answer:\AnswerCounter]%
\doifreferencefoundelse{question:\AnswerCounter}
{\goto{#1}[question:\AnswerCounter]}
{#1}}
\defineenumeration
[question]
[text=Question,
headcommand=\QuestionTextCommand]
\defineenumeration
[answer]
[text=Answer,
headcommand=\AnswerTextCommand]
\defineblock[answer]
\startbuffer
%
\startquestion
\input knuth
\stopquestion
%
\beginanswer
\startanswer
\input knuth
\stopanswer
\endanswer
%
\stopbuffer
\starttext
\dorecurse{10}{\getbuffer}
\page
\useblocks[answer]
\stoptext
%%%% end example
