Assessment
Classification of Pregnancy
A. Gravida number of times pregnant,
regardless of duration, including the present
pregnancy.
!. Primagravida pregnant for the first time
". #$ltigravida pregnant for second or
subsequent time
%. Para number of pregnancies that lasted more
than 20 weeks, regardless of outcome.
!. N$lli&ara a woman who has not given
birth to a baby beyond 20 weeks’ gestation.
". Primi&ara a woman who has given birthto one baby more than 20 weeks’ gestation.
'. #$lti&ara Woman who has had two or more
births at more than 20 weeks’ gestation. . . twins
or triplets count as 1 para.
(. !"#$ !ara subdivided to reflect births that
went to Term, Premature births, A bortions, and
Living children.
)se of GTPAL !regnancy outcomes can be
described with the acronym
GTPAL.
1. G is gravidity, the number of pregnancies,
including the present one.
2. T is term *irt+s, the number born at term
%longer than &' weeks( gestation).
&. P is &reterm *irt+s, the number born before
&' weeks( gestation.
*. A is a*ortions and+or miscarriages, the
number of abortions and+or miscarriages
%included in gravida if before 20 weeks(
gestation included in parity if past 20 weeks(gestation). -ote that a termination of the
pregnancy after 20 weeks is referred to as a
therapeutic termination./
. L is t+e n$m*er of c$rrent living c+ildren.
. N,gele-s r$le for estimating the date of
confinement
1. 3se of N,gele-s r$le requires that the woman
have a regular 245day menstrual cycle.
2. "dd ' days to the first day of the last
menstrual period, subtract & months, and thenadd 1 year to that date alternatively, add ' days
to the date of the last menstrual period and count
forward 6 months.
Determination of Pregnancy
7iagnosis of pregnancy is based on
pregnancy5related physical and hormonal
changes and are classified as presumptive,
probable, or positive.
Presumptive Signs and Symptoms (Subjective)
hese changes may be noticed by the
mother+health care provider but are not
conclusive for pregnancy.
A. "menorrhea %cessation of menstruation)
%. -ausea and vomiting
C. 3rinary frequency
D. 8atigue
E. 9reast changes
. Weight changeG. :kin changes
H. ;aginal changes including leukorrhea
I. ost tests rely on the presence of ?@ in the
blood or urine of the woman.
". Aasy, ine=pensive, but may give false
readings with any handling error, medications,
or detergent residue in laboratory equipment.
'. A=ception is the radioimmunoassay %BC"),
which tests for the beta subunit of ?@ and is
considered to be so accurate as to be diagnostic
for pregnancy.

Positive Signs and Symptoms
hese signs emanate from the fetus, are
noted by the health care provider, and are
conclusive for pregnancy.
A. etal +eart*eat$ detected as early as eighth
week with an electronic device after 1Gth week
with a more conventional auscultory device.
%. !alpation of fetal outline.
C. !alpation of fetal movements.
D. 7emonstration of fetal outline by either
ultrasound %after si=th week) or H5ray %after
12th week).
)NDAL HEIGHT
". 8undal height is measured to evaluate thegestational age of the fetus %
9. 7uring the second and third trimesters %weeks
14 to &0), fundal height in centimeters
appro=imately equals fetal age in weeks I 2 cm
. "t 1G weeks, the fundus can be found
appro=imately halfway between the symphysis
pubis and the umbilicus.
7. "t 20 to 22 weeks, the fundus is
appro=imately at the location of the umbilicus.
A. "t &G weeks, the fundus is at the =iphoid
process.

#ATERNAL RI23 ACTOR2
". German measles 4r$*ella5
1. he risk of maternal and fetal or congenital
infection is related to the trimester of placental
infection.
2. >aternal infection during the first 4 weeks of
gestation carries the highest rate of fetal
infection.
9. 2e/$ally transmitted infections
1. 2y&+ilisa. Jrganism may cross the &lacenta.
b. Cnfection usually leads to spontaneous
abortions.
c. Cnfection increases the incidence of mental
subnormality and physical deformities.
2. Genital +er&es
a. Jrganism may cross the &lacenta.
b. 8etus is contaminated after membranes
rupture or with vaginal delivery.
&. Gonorr+ea
a. 8etus is contaminated at the time of delivery.
b. >aternal infection may result in postpartum
infection of theneonate.
c. Bisks to the neonate include ophthalmia
neonatorum, pneumonia, and sepsis.
C. H$man imm$nodeficiency vir$s 4HI65
1. he virus is transmitted through blood, blood
products, and other bodily fluids, such as urine,
semen, and vaginal secretions.
2. Bepeated e=posure to the virus during
pregnancy through unsafe se=
practices or intravenous drug use can increase
the risk of transmission to the fetus.
&. !erinatal administration of Eidovudine %K7;)
may be recommended to decrease the
transmission of ?C; virus from mother to fetus.
7. 2$*stance a*$se
1. >any substances cross the &lacenta7
therefore, no drugs, including over5the5counter
medications, should be taken unless prescribed by a health care provider.
2. :ubstances commonly abused include
alcohol, cocaine, crack, mariLuana,
amphetamines, barbiturates, and heroin.

&. :ubstance abuse threatens normal fetal
growth and successful term completion of the
pregnancy.
*. :ubstance abuse places the pregnancy at risk
for fetal growth restriction, abruptio placentae,
and fetal bradycardia.. !hysical signs of drug abuse may include
dilated or contracted pupils, fatigue, track
%needle) marks, skin abscesses, inflamed nasal
mucosa, and inappropriate behavior by the
mother.
G. onsumption of alcohol during pregnancy
may lead to fetal alcohol syndrome %8":) and
can cause Litteriness, physical abnormalities,
congenital anomalies, and growth deficits.
'. :moking can result in low birth weight, a
higher incidence of birth defects, and stillbirths.
A. ;iral hepatitis
8. Adolescent ®nancy
1. 8actors that result in adolescent pregnancy
include the early onset of menarc+e, changing
se=ual behaviors in this age group, problems
with family relationships, poverty, and the lack
of knowledge of reproduction and birth control.
2. he maLor concerns related to adolescent
pregnancy include poor nutritional status,emotional and behavioral difficulties, lack of
support systems, increased risk of stillbirth, low5
birth5weight infants8 fetal mortality,
cephalopelvic disproportion, and increased risk
of maternal complications, such as hypertension,
anemia, prolonged la*or8 and infections.
&. he role of the >idwife in reducing risks and
consequences of adolescent pregnancy is
twofoldMfirst, to encourage early and continued
prenatal care and second, to refer the
adolescent, if necessary, for appropriate
assistance, which can help counter the effects of
a negative socioeconomic environment.

CO#PLICATION2 O PREGNANCB
!regnancy can be complicated by
situations unique to childbearing %e.g., placental bleeding), or by longstanding conditions
predating pregnancy and continuing into the
childbearing process %e.g., age, socioeconomic
status, cardiac problems) for common
discomforts of pregnancy
General #idifery Res&onsi*ilities
A. each danger signals of pregnancy early in
prenatal period so that client is aware of what
needs to be reported to health care provider on
an immediate basis
%. 9e aware that early teaching allows the client
to participate in the identification and reportingof symptoms that can indicate a problem in her
pregnancy.
C. Aarly recognition and reporting of danger
signals usually results in diminishing the risk
and controlling the severity of maternal+fetal
complications.
D. Cnterventions are specific for the individual
risks.
E. Avaluation centers around whether or not the
risk was controlled or eliminated, and how the
maternal+fetal reaction was controlled.

par for the course, but others are cause for alarm.
?ow do you know the differenceO
!. %leeding
9leeding means different things
throughout your pregnancy. Cf you are bleeding
heavily and have severe abdominal pain and
menstrual5like cramps or feel like you are going
to faint during first trimester, it could be a sign
of an ecto&ic ®nancy,/
?eavy bleeding with cramping could
also be a sign of miscarriage in first or early
second trimester. 9y contrast, bleeding with
abdominal pain in the t+ird trimester may
indicate &lacental a*r$&tion, which occurs
when the placenta separates from the uterine
lining.
2. 2evere Na$sea and 6omiting
Ct(s very common to have some nausea when
you(re pregnant. Cf it gets to be severe, that may
be more serious. Cf you can’t eat or drink
anything, you run the risk of becoming
dehydrated,/
