A nurse is assessing a client who is 6 months pregnant. Which findings should the nurse expect? (Select all four options that apply.)

A. Hypoactive oil and sweat glands: Pregnancy typically causes increased activity in oil and sweat glands, not decreased. B. Increased skin pigmentation: Increased pigmentation is common during pregnancy, often affecting areas like the areolas and abdomen. C. Persistent migraine headaches: While some women may experience headaches in pregnancy, they are not an expected or typical finding and may require further assessment. D. Facial edema: Mild facial edema can occur as pregnancy progresses, especially due to increased blood volume and fluid retention. E. Melasma: Melasma, or "mask of pregnancy," is a common finding characterized by dark patches on the face due to hormonal changes. F. Linea nigra: Linea nigra is a dark line that often appears on the abdomen during pregnancy as a result of hormonal changes.
