Their historically were issues from any of the allied health professions then applying into medicine. Nursing and pharmacy had the lowest admission rates for many years. It is doable, but you are going to have to have an excellent explanation beyond just job matters why not continue onto the NP track especially if you desire primary care options. Nursing, pharmacy, and clinical lab sciences are worse than neutral for this reason, but a great candidate is a great candidate, and most of the very prejudiced faculty are being phased out. One other note, the GPA standards do not change for your major, bear in mind that nursing is considered to be one of the harder majors but you will need to keep the GPA up.
