In summary, the nurse is the assistant of the doctor in providing preventive and curative health services for the child. She is the person in closest contact with the patient and the family—in the hospital, the clinic and the home; also with the child, the family and the teacher in the school. Therefore she is the key person in a position to carry out health teaching. She must assume responsibility for teaching and supervising thedais if maternal and infant morbidity and mortality rates are to be reduced appreciably in the near future. If school health services are to be developed on a sound basis, the ratio of nurses to doctors in the school health team should be such that there are sufficient nurses to carry health teaching to the pupils, the teachers and the parents.
