Immediately after her graduation, Hutner began working in the surgical department at the School of Hygiene. Winning a scholarship from the government to further her education, she traveled to England in 1938 and enrolled at the
Queen's Nursing Institute. Graduating in 1939, the outbreak of
war delayed her return home and she remained in England, working for the
Willesden District Nursing Association. She was one of the nurses who assisted the wounded during the
bombing of London in 1940. In 1944, she attended additional courses at the
Southend-on-Sea Hospital in
Essex and upon completion of her studies went to work at the
St James' Hospital in London. Hutner remained active there until she attained a scholarship to attend studies in the United States in 1947. She traveled to
Detroit, Michigan and attended
Wayne State University in 1947 and 1948, graduating from the School of Pedagogy. In 1948, Hutner returned to Warsaw and began her career at the Ministry of Health, recognizing the nursing shortage caused by the war and inadequate training facilities. She pressed for the organization of the Training Center for Nursing Instructors which opened in 1949 and for which she served as director. Simultaneously, she proposed a center for nurses and candidates to improve their proficiency, though it would not be established until 1961. Hutner was one of the co-founders of the
Polish Nursing Association, which was established in 1958. In 1960, after receiving a fellowship from the
Rockefeller Foundation, Hutner went on a tour of the
Nordic countries to evaluate nursing practices, standards and educational facilities. Returning from abroad, she opened the nurses' training school, which would be renamed in 1962 as the Central Medical Personnel Development Center (). She would direct this organization until her retirement, publishing two nursing textbooks,
Podręcznik dla pielęgniarek (
Manual for Nurses, 1958) and
Pielęgniarstwo specjalistyczne (
Specialized Nursing, 1962). Hutner took a course offered by the
World Health Organization (WHO) in Denmark in 1964 to study
nursing management and the following year was asked to represent the Polish Nursing Association as their delegate for the
International Council of Nurses (ICN). She was selected by the ICN to serve on the Admissions Committee for two terms. For seven years she was a
lecturer at the
Medical University of Lublin for the Nursing Department and taught courses at the Mother and Child Institute
(pl) () in Warsaw. She was also an instructor and expert consultant for the WHO until 1968. ==Post-retirement==
