  1. Folic acid supplementation during pregnancy is to:a. Improve the bone density of pregnant women b. Decrease the incidence of neural tube defects in the fetus c. Decrease the incidence of Down syndrome in the fetusd. Improve calcium uptake in pregnant women

 

ANS: b

  Feedback
a. Folic acid is not related to bone density.
b. Correct. The use of folic acid has decreased the incidence of neural tube defects by 50%.
c. The use of folic acid is not associated with a reduction in Down syndrome.
d. Folic acid is not related to calcium uptake in women.

  1. The positive signs of pregnancy are:a. All physiological and anatomical changes of pregnancyb. All subjective signs of pregnancyc. All those physiological changes perceived by the woman herselfd. The objective signs of pregnancy that can only be attributed to the fetus

 

ANS: d

  Feedback
a. Physiological and anatomical changes of pregnancy are presumptive signs of pregnancy.
b. All subjective signs of pregnancy are the probable signs of pregnancy.
c. All those physiological changes perceived by the woman herself are presumptive signs of pregnancy.
d. Correct. Positive signs of pregnancy are the objective signs of pregnancy that can only be attributed to the fetus, such as fetal heart tones.

  1. During a routine prenatal visit in the third trimester, a woman reports she is dizzy and lightheaded when she is lying on her back. The most appropriate nursing action would be to:a. Order an EKG.
  2. Report this abnormal finding immediately to her care provider.
  3. Teach the woman to avoid lying on her back and to rise slowly because of supine hypotension.
  4. Order a nonstress test to assess fetal well-being.

 

ANS: c

  Feedback
a. This is a normal occurrence in pregnancy and does not indicate pathology. The probable cause of the problem is supine hypotension.
b. This is a normal finding that does not warrant immediate notification to her care provider.
c. Correct. Teaching the woman to avoid lying on her back because of occlusion of the vena cava with the gravid uterus causes supine hypotension syndrome.
d. Antenatal testing is not indicated with supine hypotension.

  1. Blood volume expansion during pregnancy leads to: a. Iron-deficiency anemiab. Maternal iron stores being insufficient to meet the demands for iron in fetal developmentc. Plasma fibrin increase of 40% and fibrinogen increase of 50%d. Physiological anemia of pregnancy

 

ANS: d

  Feedback
a. Iron-deficiency anemia is treated with iron supplementation. Iron-deficiency anemia is defined as hemoglobin of less than 11 g/dL and hematocrit less than 33%.
b. Maternal iron stores that are insufficient to meet the demands for iron in fetal development result in iron-deficiency anemia.
c. Hypercoagulation that occurs during pregnancy is to decrease the risk of postpartum hemorrhage. These changes taking place are not related to blood volume expansion.
d. Correct. Physiological anemia of pregnancy, also referred to as pseudo-anemia of pregnancy, is due to hemodilution. The increase in plasma volume is relatively larger than the increase in RBCs that results in decreased hemoglobin and hematocrit values.
