How can a woman working in the health sector adhere to the legitimate hijab while being obligated to wear a medical uniform? And what is the ruling on a woman working and studying in the field of obstetrics (midwifery) given the mixing with doctors, and is she required to abandon her studies or work to please the Creator?

There is no specific dress that a woman is obligated to wear. Rather, the conditions of the legal hijab (definition) must be met. As for a doctor's mixing with and dealing with women, there is no harm in it, unless there is a fitna (temptation) or a lack of adherence to Islamic regulations. In such a case, it is not permissible except out of necessity or an urgent need.
