Final answer:
The nurse's observation of very few options for prenatal care in a largely African American community is an example of a health disparity.
Step-by-step explanation:
The nurse's observation of very few options for prenatal care in a largely African American community is an example of a health disparity. Health disparities refer to differences in health outcomes and access to healthcare that are closely linked to social or economic disadvantages. In this case, the lack of prenatal care options in the community is contributing to higher infant mortality rates among African American infants.
