    • The body experiences many anatomical/physiologic changes during pregnancy. Findings in a physical assessment that would be considered abnormal in the nonpregnant client may be a result of pregnancy and not an abnormal state.
    • In this chapter, the physical changes that occur in a woman as a result of pregnancy are identified as normal variations. Changes that are not a result of pregnancy or that represent an abnormal state during pregnancy are identified as deviations from normal.
