Agreed.
Simple to store a list of already asked questions in the session scope.

Another way is to leave the already asked
There are more efficient ways of getting a single random record from the
database. You are grabbing them all every time when you only need 1.
SQL Server:
SElECT TOP 1 q.questionid, q.questiontext FROM questions q ORDER BY NEWID()
MySQL
SELECT q.questionid, q.questiontext FROM questions q ORDER
Another way is to leave the already asked questions out of your new
query each time:
SELECT questions.questionid, questions.questiontext
FROM questions
WHERE questions.questionid NOT IN (#listOfPreviouslyAskedQuestions#)
#questiontext#

Either keep a list of questions already asked and query again if it
tries to give you one you've had before or keep a a copy of the query
for each user and remove the row after you ask each question.
