The initial examination in the first stage of labor involves taking a medical history, performing a physical examination including vital signs and abdominal/pelvic exams, and monitoring the fetus. The midwife obtains consent for exams and procedures, provides emotional support, and observes the woman's progress through the stages of labor using a partograph to chart cervical dilation and other indicators. Proper nutrition, positioning, bladder care, and infection prevention protocols are followed during labor management.
