CH 4: PRENATAL CARE AND
ADAPTATIONS TO PREGNANCY
QUESTIONS AND CORRECT ANSWERS
Amenorrhea, nausea, breast tenderness, deepening pigmentation, urinary frequency,
and quickening are all signs of which general group sign of pregnancy? - Answer-
Presumptive (can be a symptom of pregnancy but, could also be something else.)
Audible fetal heartbeat, fetal movement felt by examiner, ultrasound visualization of
fetus are all signs of which general group of pregnancy ? - Answer-Positive
Goodwell's sign, Chadwicks sign, Hegar's sign, McDonald's sign, abdominal
enlargement, Braxton Hick's contractions, Ballottement, Striae, and positive pregnancy
test are all which signs of pregnancy? - Answer-Probable
When is quickening often felt by the mother? - Answer-16 to 20 weeks
Define Goodwell's sign? - Answer-The softening of the cervix and vagina caused by
vascular congestion (engorgement)
What is Chadwick's sign? - Answer-Purplish-blueish discoloration of the cervix, vagina,
and vulva caused by increased vascular congestion (engorgement)
The softening of the lower uterine segment is defined as? - Answer-Hegar's sign
What is the McDonald's sign? - Answer-The softening of the cervix makes easy to flew
the body of the uterus against the cervix
A maneuver by which the fetal part is displaced by a light tap of the examining finger on
the cervix, and then the part rebounds quickly. - Answer-Ballottement
hCG is produced by what structure? - Answer-chronic villi of the placenta
What are the ranges of the fetal heart rate for a term baby? - Answer-low of 110-120
and high of 150-160
What is the function of the mucous plug? - Answer-To prevent the ascent of vaginal
organisms into the uterus.
What weeks is there usually a screening and treatment period for bacterial vaginosis? -
Answer-12-20
, Increased estrogen levels during pregnancy cause edema/ swelling of the mucous
membranes of what structures? - Answer-- mouth
- pharynx
- nose
- trachea
What is the purpose of the 45% increase in blood volume in the pregnant woman? -
Answer-- Exchange in nutrients, oxygen, and waste products w/i placenta
- Needs of expanded maternal tissue
- Reserve for blood loss during birth
What blood pressure would cause alarm to you, as the nurse, from a pregnant woman?
- Answer-140/90 mm/Hg or greater
This condition is caused when the pregnant woman lies on her back. - Answer-Supine
HTN syndrome/ Aortacaval compression/vena cava syndrome (when heavy uterus
compresses inferior vena cava reducing the amount of blood returned to her heart.
Circulation to placenta may also be reduced leading to fetal hypoxia.)
Fatigue, lightheadedness, dizziness and agitation are all signs of what condition? -
Answer-Supine HTN syndrome
Where is estrogen produced and what is it's significance during pregnancy? - Answer--
Produced by ovaries and placenta
- Responsible for enlargement of breasts/uterus/genitalia; promotes fat deposit
changes; stimulates melanocyte stimulating hormone in hyperpigmentationof skin;
promotes vascular changes; promotes development of striae and alters sodium and
water retention
Where is progesterone produced and what are it's functions? - Answer-- Produced by
corpus lute and ovary then later the placenta.
- Maintains endometrium for implantation, inhibits uterine contractility (preventing
miscarriage); promotes development of secretory ducts of breasts; stimulates sodium
secretion; reduces smooth muscle tone causing constipation/heartburn/varicosities
(thick veins)
What increases the chance of thrombophlebitis (blood clot in vein) during pregnancy? -
Answer-Increased levels of clotting factors VII, VIII, and X and plasma fibrinogen during
2nd and 3rd trimesters
What are the functions of Thyroxine 4 during pregnancy? - Answer-Influences thyroid
gland size/activity; increase HR; increase BMR by 23%
What is the source and significance of hCG? - Answer-- Produced by trophoblastic
tissue; stimulates progesterone/estrogen by corpus luteum
