Mary L. Dunlap MSN, APRN
Fall 2015
High-Risk Pregnancy
• Jeopardy to mother, fetus, or both
• Condition due to pregnancy or result
of condition present before pregnancy
• Higher morbidity and mortality
• Risk assessment with first Antepartal
visit and each subsequent visit
• Risk factors (see Box 19-1 p.605)
Conditions Complicating
Pregnancy
•
•
•
•
•
•
Perinatal Loss
Bleeding
Hyperemesis gravidarum
Gestational hypertension
HELLP syndrome
Gestational diabetes
Perinatal Loss
• Death of a fetus or newborn no matter
when it occurs is devastating to the mother
and family
• Nurses need to understand their own
personal feelings so they can provide
support and compassionate care
• What to say- I understand , I am here to
listen, Does your baby have a name
Fetal Demise
• Fetal Demise True Story
Causes of Bleeding
• Spontaneous
abortion
• Ectopic
pregnancy
• GTD/Hydatiform
mole
• Cervical
insufficiency
• Placenta Previa
• Abruptio
placenta
Spontaneous Abortion
• Termination of pregnancy before
viability prior to 20wks less than 500g
• Presentation-Vaginal bleeding and
cramping
• Management-Bed rest, serial hCG’s &
H&H, Dilation and curettage may be
necessary to remove products of
conception, RhoGam if mother RH -

Drug use
Infection
Categories of Abortions
• Complete–all products of conception
expelled
• Incomplete–a portion of the products of
conception retained in the uterus
• Threatened–bleeding and cramping
Categories of Abortions
• Missed– nonviable embryo retained in
uterus for at least 6 weeks
• Habitual–three or more successive
abortions
• Inevitable–cannot be stopped
• Table 19-1 pg. 607
Spontaneous Abortion
Nursing care
• Assess bleeding and signs of shock
• Assess pain level
• Assess for infection
• Provide emotional support
Ectopic Pregnancy
• Fertilized ovum implanted outside the
uterine cavity usually due to an
obstruction of the fallopian tube
• 95%- 99% occur in the fallopian tube
• Possible implantation sites Fig 19-1
pg 531
Contributing Factors

•
•
•
Previous ectopic
STD’s
Endometriosis
Tubal or pelvic
surgery

prepare for surgery & provide
emotional support
Gestational Trophoblastic Disease
(GTD)
• GTD is a disease characterized by an
abnormal placental development
resulting in the production of fluid filled
grape like clusters and vast
proliferation of Trophoblastic tissues
• Diagnosis- trans vaginal U.S. showing
vesicular molar pattern (grape clusters)
high hCG levels
GTD
• Complete (or classic): mole results
from fertilization of egg with lost or
inactivated nucleus and is associated
with Choriocarcinoma
• Partial mole: result of two sperm
fertilizing a normal ovum
• Cause unknown
GTD
Clinical manifestations
• Bleeding grape like tissue
• Sever Hyperemesis
• Uterine size larger than dates
• Extremely high hCG levels
• Early development preeclampsia

• Early development of preeclampsia
(prior to 24 wks.)
Cervical Insufficiency
• Premature cervical dilatation due to a
weak structurally defective cervix that
spontaneously dilates in the absence
of contractions in the 2nd trimester
• 18–22 wks. Usual time for
development
• Repetitive second trimester losses
Cervical Insufficiency
Possible causes
• Trauma to the cervix
• Structure of cervix- less collagen and
more smooth muscle

components
Diabetes Mellitus
• Diabetes mellitus is the most common
endocrine disorder associated with
pregnancy
• Before discovery of insulin in 1922, it
was uncommon for a woman with
diabetes to give birth to a healthy baby
• Pregnancy complicated by diabetes is
considered high risk
Diabetes Mellitus
• Metabolic disease characterized by
hyperglycemia due to defects in insulin
secretion, insulin action, or both.
• Type 1
• Type 2
• Gestational diabetes mellitus (GDM)
Pregestational Diabetes Mellitus
Goal
• Preconception counseling and early
pregnancy glycemic control during
organogenesis to reduce the risks of
birth defects
• Fetal Basis of Adult Disease Theory

mode of birth
Diabetes Mellitus- Gestational
(GDM)
• Impairment in CHO metabolism during
pregnancy due to placental hormones
• Placental hormones cause insulin
resistance
• Beta Cells are unable to produce the
required amount of insulin
• Develops during the second trimester
Insulin Needs during Pregnancy
• First trimester: reduced
• Second trimester: starts to increases
• Third trimester: peaks to provide more
nutrients for the fetus
• Delivery: Maternal insulin needs drop
to prepregnancy
• Breastfeeding mother: lower insulin
needs

Blood Incompatibility
Blood type incompatibility
• ABO incompatibility: type O mothers
& fetuses with type A or B blood (less
severe than Rh incompatibility)
Blood Incompatibility
Rh incompatibility
• Exposure of Rh-negative mother to Rhpositive fetal blood causes sensitization
and antibody production
• Risk increases with each subsequent
pregnancy and fetus with Rh-positive
blood
Blood Incompatibility
• Nursing assessment: maternal blood type
and Rh status
• Antibody screen (indirect Coombs)
• Nursing management: RhoGAM at 28
weeks
Hydramnios
• Also known as polyhydramnios, too
much fluid ( greater than 2000ml)
• Occurs 32-36 weeks

encourage the best blood flow to the
fetus
• Assist with amnio infusion
Multiple Gestation
• More than one fetus being born to a
pregnant women
• The number of multiple gestations
have increased due to the use of
fertility drugs
• These women are at higher risk for
complications
Multiple Gestation
• Monozygotic( Identical)- single fertilized
ovum that splits. There is one placenta
and chorion and two bags of amniotic
fluid
• Dizygotic (Fraternal)- two eggs /sperm
There are two placentas, chorions and
bags of amniotic fluid
Multiple Gestation
Multiple Gestation

Preterm Labor
• Regular uterine contractions with
cervical change between 20 to 37
weeks gestation.
• Most common complication
• Cause is not always known
• Usually due to infection or over
distended uterus
Preterm Labor
Signs of labor
• Lighting- fetus dropped into pelvic
cavity
