Which of the following time-based descriptions of a stage of development of pregnancy is accurate?
 
  1. Viability: 22 to 37 weeks since last menstrual period (assuming fetal weight greater than 500 g)
  2. Term: pregnancy from beginning of week 38 of gestation to the end of week 42
  3. Preterm: pregnancy from 20 to 28 weeks
  4. Postdate: pregnancy that goes beyond 38 weeks

Question 2

Metabolic changes throughout pregnancy affecting glucose and insulin in the mother and the fetus are complicated but important to understand. Nurses should know that:
 
  1. insulin crosses the placenta to the fetus only in the first trimester, after which the fetus secretes its own.
  2. women with insulin-dependent diabetes are prone to hyperglycemia during the first trimester because they are consuming more sugar.
  3. during the second and third trimesters, pregnancy exerts a diabetogenic effect that ensures an abundant supply of glucose for the fetus.
  4. maternal insulin requirements steadily decline during pregnancy.

Answer to Question 1

2
1. Incorrect. Viability is the capacity of the fetus to live outside the uterus before coming to term 22 to 24 weeks since LMP.
2. Correct. Term is 38 to 42 weeks of gestation.
3. Incorrect. Preterm is 20 to 37 weeks of gestation.
4. 1. 4. Incorrect. Postdate or postterm is a pregnancy that goes beyond 42 weeks or what is considered the limit of full term.

Answer to Question 2

3
1. Incorrect. Insulin never crosses the placenta; the fetus starts making its own around the 10th week.
2. Incorrect. As a result of normal metabolic changes during pregnancy, insulin-dependent women are prone to hypoglycemia (low levels).
3. Correct. Pregnant women during the second and third trimesters develop increased insu-lin resistance.
4. Incorrect. Maternal insulin requirements may double or quadruple by the end of preg-nancy.
