You take a hit for any "hard" credit inquiries (like Kohls checking your report before they issued credit). You take a second hit for opening a new account. And you take a third hit for using the full amount of the new credit line all at once. The hit for the inquiry and the new account will go away with time, there is nothing you can do about it. The hit for maxing out the new line will go away as you make payments to reduce the balance. After several months of making on time payments, and keeping your balance low, your score should start to go higher than when you started. But it will take a while.
