What nursing, non-nursing theories, or family theories could be
used for this patient?
SE lack social support since her core family lives in Arizona
and all other relatives live in California but do not communicate
on regular basis. she is a single parent, and this could lead
to feeling isolated, and such feelings can contribute to
loneliness and depression. She may feel overwhelmed by the
responsibility of juggling caring for her daughter, keeping up with
the bills and household chores and visitation and custody problems
may come in the future.
