Many parents-to-be have questions about multiple births. Maternity nurses should be able to tell them that:
 
  a. Twinning and other multiple births are increasing because of the use of fertility drugs and delayed childbearing.
  b. Dizygotic twins (two fertilized ova) have the potential to be conjoined twins.
  c. Identical twins are more common in white families.
  d. Fraternal twins are same gender, usually male.

Question 2

The nurse caring for a pregnant client knows that her health teaching regarding fetal circulation has been effective when the client reports that she has been sleeping:
 
  a. In a side-lying position.
  b. On her back with a pillow under her knees.
  c. With the head of the bed elevated.
  d. On her abdomen.

Answer to Question 1

ANS: A
If the parents-to-be are older and have taken fertility drugs, they would be very interested to know about twinning and other multiple births. Conjoined twins are monozygotic; they are from a single fertilized ovum in which division occurred very late. Identical twins show no racial or ethnic preference; fraternal twins are more common among African-American women. Fraternal twins can be different genders or the same gender. Identical twins are the same gender.

Answer to Question 2

ANS: A
Optimal circulation is achieved when the woman is lying at rest on her side. Decreased uterine circulation may lead to intrauterine growth restriction. Previously it was believed that the left lateral position promoted maternal cardiac output, enhancing blood flow to the fetus. However, it is now known that the side-lying position enhances uteroplacental blood flow. If a woman lies on her back with the pressure of the uterus compressing the vena cava, blood return to the right atrium is diminished. Although having the head of the bed elevated is recommended and ideal for later in pregnancy, the woman still must maintain a lateral tilt to the pelvis to avoid compression of the vena cava. Many women find lying on her abdomen uncomfortable as pregnancy advances. Side-lying is the ideal position to promote blood flow to the fetus.
