Final answer:
In advanced specialty nursing, nurse anesthetists are registered nurses with additional training to provide specialized anesthesia care. They can sometimes work independently. Nurse midwives also have specialized training but usually collaborate with physicians for high-risk pregnancies.
Step-by-step explanation:
The role included in advanced specialty nursing is that nurse anesthetists are registered nurses. Advanced practice registered nurses (APRNs), such as nurse anesthetists and nurse midwives, have additional training and education that allow them to provide more specialized care. For instance, nurse anesthetists must complete a graduate-level program and are trained to provide anesthesia and related care before, during, and after surgical, therapeutic, diagnostic, and obstetrical procedures. They can work independently in some states, subject to varying regulations. On the other hand, nurse midwives provide care to women, including gynecological exams, family planning services, prenatal care, and attending childbirth, but they generally do not care for women with high-risk pregnancies without collaboration with a physician.
