If the I-130 has been approved, then she will not be issued the K-3 visa but will have to apply for the immigrant visa on the basis of the approved I-130 at the US Consulate in Lima (if that's where she still is) and once that is approved, she will enter the US as a permanent resident.
Please let me know if you have any additional questions or if I may be of further assistance to you in this matter.
