it's because the last value of $status is unchanged. you need to modify
the code to:
$question_count = 3;
$question_id = 2;
foreach (range(1, 5) as $number) {
$status = '';
if ($question_id == $number) {
$status = "_selected";
}
elseif ($question_count < $number) {
$status = "_blank";
}
echo "q" . $number . $status . ".gif<br>";
