Many parents-to-be will have questions about multiple births. Maternity nurses should be able to tell them that:
 
  1. twinning and other multiple births are increasing because of fertility drugs and delayed childbearing.
  2. dizygotic twins (two fertilized ova) are the ones with the potential to be Sia-mese, or conjoined twins.
  3. identical twins are more common in Caucasian families.
  4. fraternal twins are same sex, usually male.

Question 2

Of the following psychosocial factors, which has the least negative effect on the health of the mother or fetus?
 
  1. Moderate coffee consumption
  2. Moderate alcohol consumption
  3. Cigarette smoke
  4. Emotional distress

Answer to Question 1

1
1. Correct. If the parents-to-be are older and have taken fertility drugs, they would be very interested in this information.
2. Incorrect. Siamese twins are monozygotic, from one fertilized ova, in which division oc-curred very late.
3. Incorrect. Identical twins show no racial or ethnic preference; fraternal twins are more common among African-American women.
4. Incorrect. Fraternal twins can be different sexes or the same. Identical twins are the same sex.

Answer to Question 2

1
1. Correct. Three or more cups a day need to be consumed for a slight risk of a slight decrease in birth rate. Alcohol, cigarette smoke, and emotional distress have potentially much greater nega-tive effects on the health of the fetus (and the mother).
2, 3, 4. Incorrect. Three or more cups a day need to be consumed for a slight risk of a slight de-crease in birth rate. Alcohol, cigarette smoke, and emotional distress have potentially much greater negative effects on the health of the fetus (and the mother).
