Day 5: 5:00 PM - 6:00 PM - S5-E11
Continuity mistake: When Agent Aaron Pierce steps out of the helicopter, the right half of his face is severely wounded, with lots of blood and a bandage on it. 12 minutes later, when he is back in the Presidential house, he's talking with Miss. Logan and his face is completely clean, with not a single scratch or sign of wounds on his right half of the face. (00:12:55 - 00:25:00)
Answer: According to Jack in season 5, Nina was "deep cover" before the pair ever met, so it's safe to assume she was recruited before she joined CTU. As for what her primary mission was, who knows? Perhaps it was to gather sensitive intel and pass it on to her superiors. Given that she worked for an intelligence agency, it's not a stretch. Or perhaps we may find out in season seven.
