An analysis of aborted tissues reveals that the fetus had an aneuploid condition. The nurse asks the mother if her menstrual periods are generally regular. What is the rationale for this question?

▸ Many spontaneous abortions occur before the mother is aware she is pregnant.

▸ Menstrual irregularities signal hormone alterations that may cause aneuploidy.

▸ Spontaneous abortion often "resets" a woman's hormonal cycle, making periods more regular.

▸ Aneuploidy's greatest effects are on the secondary sexual characteristics.
