H ES I H int
Ovulation occurs approximately 14 days before the next menstrual cycle.
H ES I H int
To avoid pregnancy a woman should abstain from unprotected sexual intercourse during her fertile days. The
most fertile days for pregnancy are the day before ovulation and the day of ovulation. The fertile period
begins 4-5 days prior to ovulation and ends 24-48 hours after ovulation. A couple must avoid unprotected
intercourse for several days before an anticipated ovulation and for 3 days after ovulation to prevent
pregnancy because sperm can live in a woman’s body approximately 4 to 5 days and eggs live approximately
24-48 hours after being released.
Pregnancy divided into three 13-week trimesters:
1. First trimester: from the first day of LMP through 13 weeks
2. Second trimester: 14 weeks through 26 weeks
3. Third trimester: 27 weeks to 40 weeks
HESI Hint
Some women do not realize they are pregnant because they experience implantation bleeding or spotting.
Maternal changes
1. Nausea persists up to 12 weeks.
3. Hegar sign occurs (softening of the isthmus of
cervix). 4. Goodell sign occurs (softening of cervix).
5. Cervix flexes.
6. Leukorrhea increases.
9. Chadwick sign (bluing of vagina) is a presumptive sign appearing as early as 4
weeks. Nursing interventions
, 1.
1. Teach prevention of nausea.
a. Suggest eating dry crackers before getting out of bed in the morning.
b. Suggest eating small, frequent meals; avoiding fatty foods; and avoiding skipping meals.
2. Teach safety.
a. Avoid hot tubs, saunas, and steam rooms throughout pregnancy (increases risk for neural tube defects in first
trimester; hypotension may cause fainting).
12 Weeks
A. Fetal development
1. Embryo becomes a fetus.
2. Heart is discernible by ultrasound.
3. Lower body develops.
4. Sex is determinable.
5. Kidneys produce urine.
6. Fetus weighs 907.18 to 1814.4 g (2 to 4 lb)
B. Maternal changes
1. Uterus rises above pelvic brim.
2. Braxton Hicks contractions are possible (continue throughout pregnancy).
3. Potential for urinary tract infection (UTI) increases (exists throughout
pregnancy). 16 weeks : Maternal changes
1. Quickening, the mother’s first perception of fetal movement, may be noted between weeks 16 and 20.
2. Colostrum, the creamy white to yellowish premilk, may be expressed from the nipples as early as 16 weeks of
gestation.
3. Serum cholesterol increases from 16 to 32 weeks of pregnancy and remains at this level until after birth.
4. By 14 to 16 weeks, the placenta is clearly defined.
5. Insulin resistance begins as early as 14 to 16 weeks of gestation and continues to rise until it stabilizes during
the last few weeks of pregnancy.
6. Approximate weight gain of 1 lb per week beginning in the second trimester and continuing until delivery.
Nursing interventions
1. Explain the screening test, and obtain blood sample for maternal serum alpha-fetoprotein (MSAFP) between
15 and 22 weeks of gestation, ideally between 16 and 18 weeks of gestation.
a. Elevated levels are associated with open neural tube defects and multiple gestations.
b. Low levels are associated with Down syndrome. Abnormal levels are followed by second-trimester
ultrasonography for more in-depth investigation.
, 1.
2. Explain the multiple-marker, or triple-screen, blood test, and obtain a specimen for screening between 16 and
18 weeks of gestation to measure the MSAFP, human chorionic gonadotropin (hCG), and unconjugated
estriol, the levels of which are combined to yield one value.
a. Low levels may be associated with Down syndrome and other chromosomal abnormalities.
Nursing interventions
1. Explain and obtain a blood sample for a glucose challenge that is usually done between 24 and 28 weeks’
gestation.
2. At between 24 and 32 weeks’ gestation, two or three ultrasound measurements may be taken 2 weeks apart to
compare against standard fetal growth curves.
HESI Hint
Signs of healthy psychosocial maternal-fetal bonding include massaging the abdomen, nicknaming the fetus, and talking
to the fetus in utero.
Activities during First Prenatal Visit
A. Obtain history.
1. Medical history
2. Obstetrical history can be determined by two common methods:
a. Two digits: G/P only records the gravida and para of a client.
