Clearly, having worked as an LPN for 7 years, you have sufficient clinical experience. That said, unless you work shoulder-to-shoulder with physicians every day, you may need some shadowing of physicians (about 50 hours) so you have a little better picture of what a physician's work day is like. To be on the safe side, identify and shadow an osteopathic physician (DO) as DO schools like to receive a letter of recommendation from a DO on your behalf.
You have a bachelor's degree which is a general requirement.
Your GPA is very low for medical school admission and may indicate that you are lacking the fund of knowledge necessary to do well on the MCAT and in the pre-clinical coursework.
The DUI is not "nothing" but it is far down the list of things to concern yourself with as you determine whether you should go down this path.
You will need to prepare to take the MCAT and take it and do well. That will require considerable content review which might include ANKI cards, hundreds of test questions, and at least 4 full length exams, each taken in a single sitting under test conditions, and an equal amount of time reviewing what you got wrong (or right). This alone is several hundred hours of prep. (And several hundred dollars to take the test).
Although there is no grade replacement anymore at any schools, it might be wise, before beginning MCAT prep, to repeat any courses in which you received a C or less.
You might also take a look at Goro's Guide for students who need reinvention.
All-in-all, I would not recommend teeing up an application in 2024. From what you've told us, you don't seem ready.
Do it right and only do it once. This holds for both the MCAT and the application process.
