What is the importance of the "nurse's lamp" in the nonfiction book, Witches, Midwives, and Nurses?

The image of the glamorous lady with the lamp is the primacy symbol of the Nightingale nurse. The lamp and the lady who carries it represent the nursing profession as the embodiment of upper-class femininity. This image furthers the stereotype of nursing as a natural extension of a woman's inherent mothering instincts and presents her and a kindly, nurturing, and benevolent caregiver who, despite these positive attributes, has no personal agency or decision-making power in the healthcare process.
