Hii,
With 68 percentile in PPMET under general category, your chances for B.Sc Nursing in KCN , Amritsar in the first round may be limited as cut-offs tend to be higher. However, 2nd round counselling often sees a drop in cut-offs as some students withdraw or upgrade , so yes, there is a decent possibility you can get admission in 2nd round, especially if you keep your options flexible and attend the counselling on time.
Also, keep alternative private colleges as a backup and enquire directly with KCN in case they have management quota seats if not filled through counselling.
For cutoff , ranking, placements, etc you can check this:

All the best!
