The four fields of nursing are: 1. Adult nursing: it focuses on providing nursing care to adults from acute to chronic illness. 2. Mental health nursing: this field supports and promotes mental health wellbeing and ensures to offer care to those who are struggling with it. 3. Children's nursing: nursing care is offered to infants, children, and adolescents.  4. Learning disability nursing: lastly, this supports people with learning disabilities, helping them to live to their maximum potential. Nursing students have to write assignments, essays, and coursework on this subject matter. So, if you are one of them and struggling, make sure to consult professionals and ask them to do my nursing coursework.
