NUR 421 Exam 2 Practice Questions and
Correct Answers
Placental Previa ✅The placenta is implanted over cervical os rather than the body or
fundus of the uterus. C-section is necessary in nearly all women with this condition due
to risk of placental hemorrhage.
Gestational Diabetes Mellitus (GDM) ✅Glucose intolerance that did not exist/present
prior to pregnancy.
** Account for ~90% of diabetes in pregnancy
True or False: obesity increases risk of gestational diabetes ✅True:
"About 47% of GBM cases were attributed to being overweight, obese, or extremely
obese" (Durham et al., 2022, p. 175). However, not all overweight or obese women will
develop it.
How does pregnancy affect blood glucose and insulin? ✅The placenta releases
multiple hormones that antagonize/block insulin. The purpose is to prevent so much
glucose from going into mom's cells, and allowing more to go to fetus.
In response to the glucose mom is eating, insulin is being produced as normal, and in
larger amounts in response to the desensitizing hormones. This is how insulin
resistance can become so strong to the point of GDM, since moms need to pump out so
much insulin (although many women manage to maintain euglycemia despite these
changes).
When is DKA the highest risk? ✅DKA occurs in 1% of cases for women with diabetes
during pregnancy (pre-gestational or gestational). The 2nd trimester is when it's most
likely to occur.
How do insulin needs for Type 1 Diabetics change throughout pregnancy? ✅Insulin
needs certainly increase (relating to increased glucose needs & glucose going to baby;
also needing more to be absorbed, plus insulin resistance).
By the end of pregnancy, the woman may need 2-3x the amount of insulin required
before being pregnancy. Between 3-4 Humulin insulin injections may be necessary.
What is the risk of developing T2DM for women who develop GDM during pregnancy?
✅Up to 70% of with GDM will develop Type II Diabetes after birth, but only 30%-50%
will within the first 20 years s/p pregnancy.
