Soler is also called the Soles, as in "the soles of your feet." The name comes from sol-a Latin meaning to stand or be standing. In its common form, a sole is used as a reference point on footwear. A nurse's sole might be that of the patients medical status or health issues. A nurse might say, "he had an adverse reaction to his chemotherapy" referring to the patient's cancer diagnosis while being treated for a different illness altogether. An individual who has a condition that is considered serious and life threatening would use the term 'patient' rather than 'soler'.
