MTC NUR 263 Final Review 1 – OB Questions With
Complete Solutions
ABO incompatibility: Correct Answers postive coomb's test;
causes hyperbilirubinemia
Abortion Miscarriage Correct Answers expulsion of fetus
before 20 wks; major cause of bleeding; S/S: spotting/bleeding,
cramping/backache T(x):bed rest, IV's, blood transfusion, D&C,
give RHOGRAM, prepare for possible loss, encourage feelings
Abruptio placenta Correct Answers premature separation of
normally implanted placenta; S/S: dark red bleeding w/
abdominal pain, uterus hard firm and painful; cause associated
with decreased blood flow to placenta
Amniotic Fluid Correct Answers Cushion to protect FETUS &
CORD against injury
Helps control embryo's temperature
Allows symmetrical external growth of embryo
Prevents adherence of amnion to embryo
Allows freedom of movement
Can analyze to determine fetal health and maturity
10 wks-30ml, 20 wks-350ml, after 20 wks-800-1200ml
Anatomic/Physiologic changes: Breasts Correct Answers
estrogen & progesterone--> changes for lactation: nipples erect,
aerolas darken, superficial veins more prominent; colostrum
present after 12th wk
,Anatomic/Physiologic changes: Cardiovascular Correct
Answers blood volume increase, peaks 3rd tri. 40-45%
increase; HR increase 10-15 BPM; BP decrease 2nd tri.
Anatomic/Physiologic changes: Endocrine- Estrogen Correct
Answers placenta; increase vascularity causing vasodilation,
promotes enlargement of genitals, uterus, and breasts; causes
relaxation of pelvis; alters metabolism of nutrients; causes fluid
retention
Anatomic/Physiologic changes: Endocrine- Human Chorionic
Gonadotropin (hCG) Correct Answers placenta; stimulates
estrogen & progesteron by corpus luteum; basis of pregnancy
test
Anatomic/Physiologic changes: Endocrine- Human Chorionic
Somatotropin (hCS) Correct Answers placenta; antagonist of
insulin; increase amount of circulating free fatty acids for
maternal needs; decrease metabolism of glucose to allow fetal
growth
Anatomic/Physiologic changes: Endocrine- Oxytocin Correct
Answers posterior pituitary; causes uterine contractions;
stimulates ejection of milk during lactation
Anatomic/Physiologic changes: Endocrine- Pancreas Correct
Answers progressive need for increased amount of insulin-->
pregnancy hormones decrease ability to meet demand-->
gestational diabetes may develop
, Anatomic/Physiologic changes: Endocrine- Progesterone
Correct Answers placenta; plays greatest role in maintaining
pregnancy; maintains endometrium; prevents contractions; cause
fat to be deposited; helps devolop acini and lobules of breasts
Anatomic/Physiologic changes: Endocrine- Prolactin Correct
Answers anterior pituitary gland; responsible for initial
lactation; increase early in pregnancy, high levels
estrogen&progesterone inhibit lactation until birth
Anatomic/Physiologic changes: Endocrine- prostoglandins
Correct Answers may decrease placental vascular resistance;
decrease may contribute to pre-ecclampsia/toxemia; believed to
play a role in initiation of labor
Anatomic/Physiologic changes: Endocrine-
Vasopressin(antidurectic) Correct Answers posterior pituitary;
causes vasconstriction--> increase BP; helps regulate water
balance
Anatomic/Physiologic changes: eyes Correct Answers
interocular pressure increase and cornea thickens
Anatomic/Physiologic changes: Gastrointestinal Correct
Answers nausea & vomiting "morning sickness" result of
increase HCG and changed metabolism; constipation and
bloating result of progesterone->smooth muscle;
heartburn(severe=pre-ecclampsia); hemorrhoids(3rd tri)
