user16079: Can white force a draw somehow from this position using only his knight and king? 


user13928: It is not possible to force a draw. Even if Black somehow lost both pawns and his rook, the resulting endgame is still won for Black.

user12523: No. Even assuming it's White's move, Black can force mate in five moves according to the computer. But you don't really need to calculate that much since Black's material advantage is so overwhelming.
The only hope would be a stalemate, but it is unlikely. To achieve that, the knight would have to be pinned or lost, but I don't see how you can force that: if it got pinned, Black could just unpin it in the next move if necessary, or simply capture it. Even trading the queen for the knight, the position would still be easily won by Black. Black only needs to make sure that if they take the knight, they don't cause an immediate stalemate (that would be Black's blunder, not something forced by White).
Here's one of the possible lines that end with mate in five:
8/p7/6k1/2p5/6r1/2N4q/1K6/8 w - - 0 1
