Obstetrical nursing may be defined, with accuracy, as the nursing care of an obstetrical patient, but its true significance is limited only by the nurse’s ability, resourcefulness, and vision. And the more spirituality which pervades this work the more effective will be the nurse’s skilled ministrations and the more satisfying will it all be to her. This aspect of maternity nursing—what it means to the nurse herself—should be given full recognition, for although the demands which are made upon her are exacting, she will find more than compensating interest and gratification in her work. It provides a channel of expression for some of her most elemental and deeply rooted impulses. The desire to create exists within most of us, and surely the nurse tastes of the joys of creation when she watches the beautiful baby body grow and develop under her care. And she has a consciousness of patriotic service, too, for while helping to secure the immediate safety and future health of the baby citizen she is helping to build a strong race. But this work goes still further and offers even more than these. The average nurse has a deep maternal instinct. She may not be conscious of it as such, but it is this instinct which prompts her to select nursing from the wide range of occupations and professions which are open to her. And it is entirely natural that she should derive great satisfaction from this vicarious motherhood—this giving of her knowledge and skill in service to the woman with a baby in her arms. The opportunities for self-expression which are open to the nurse who gives this form of service make us wonder if she should not be included in the enviable group of those others whose life work is an expression of themselves—the poets and painters; the architects, musicians, and sculptors—those who create and build because of an urge within them. Surely, the spirit and the results of the work of the nurse who thus gives of herself may be ranged with the efforts of those others whose work is an expression of themselves. “The body is the crowning marvel in the world of miracles in which we live. Fearfully and wonderfully made, it claims our respect not only because God fashioned it, but because He fashioned it so well—because it is a thing of beauty, a perfection of mechanism.” _The Splendor of the Human Body_—BISHOP BRENT.
