While it is not possible to go directly from LPN to BSN, it is possible to go from LPN to BSN indirectly by way of a process called "rolling over". In short, after completing the RN program the student would continue on the very next semester to the BSN program without taking a break in between. They would thereby essentially be using their RN credit hours as makeshift prerequisites for the BSN program.
In the end, they would only be earning one degree. They would not be receiving both an RN degree and a BSN degree since their RN credit hours would be used for their BSN degree. https://support.eruditenursing.education/how-can-i-roll-over-from-one-program-to-another/
