ECTOPIC PREGNANCY
A: VAGINAL SPOTTING AND SLIGHT CRAMPING
Threatened
spontaneous
miscarriage (eraly:
under 16 weeks; late:
16-24 weeks)
CAU: NOT USE TAMPONS TO HALT BLEEDING AS THIS CAN LEAD TO INFECTION
Threatened
spontaneous
miscarriage (eraly:
under 16 weeks; late:
16-24 weeks)
C: POOR PLACENTAL ATTACHMENT
Imminent (inevitable)
miscarriage
A: VAGINAL SPOTTING, CRAMPING, CERVICAL DILATION
Imminent (inevitable)
miscarriage
MIC SAME CAUSE
chromosomal or
uterine abnormalities
Vaginal soptting
perhaps slight
cramping; no
apparent loss of
pregnancy
Missed miscarriage
CAU: Rarely, disseminatedintravascular
coagulationisassociatedwithmissedmiscarriage
MISSED MISCARRIAGE
A: Vaginal spotting, cramping, cervical
dilatation, but
incomplete expulsion
of uterine contents
Incomplete
spontaenous
miscarriage
CAU: High risk of uterineinfection and hemorrhage
INCOMPLETE SPON MIS
A: Vaginal spotting, cramping cervical
dilatation, and
complete expulsion of
uterine contents
COMPLETE SPON MIS
Implantation of zygote
at site other than in
uterus, associated with
tubal constrictures
ECTOPIC PREG
Sudden unilateral
lower abdominal
quadrant pain;
minimal vaginal
bleeding, possible
signs of hypovolemic
shock or hemorrhage
ECTOPIC PREG
May haverepaetectopic pregnancyinfuture if tubal scarringis bilateral
ECTOPIC PREGNANCY
SECOND TRIM
GESTATIONAL TROPHOBLASTIC DISEASE (HYDATIDIFORM MOLE)
PREMATURE CERVICAL DILATATION
C: Abnormal proliferation
of trophoblasts cells;
fertilization or division
defect
Gestational
trophoblastic disease
(hydatidiform mole)
CAU: Retained trophoblasttissue may becomemalignant
(choriocarcinoma);
followup for extendedmonitoring withhCGtesting.
Gestational
trophoblastic disease
(hydatidiform mole)
A: Overgrowth of uterus;
highly positive human
chorionic
gonadotropin (hCG)
test; no fetus present
on ultrasound;
bleeding from vagina
of old or fresh blood
accompanied by cyst
formation
Gestational
trophoblastic disease
(hydatidiform mole)
C: Low implantation of
placenta possibly
because of uterine
abnormality
Placenta previa
Cervix begins to dilate
and pregnancy is lost
at about 20 weeks;
unknown cause but
cervical trauma from
prior cervical
procedures may be
associated.
Premature cervical
dilatation
A: Painless bleeding
leading to expulsion of
fetus
Placenta previa
Can have cervical
sutures placed subsequent pregnancy to help prevent recurrence
Premature cervical
dilatation
Painless bleeding
leading to expulsion of
fetus
Premature cervical
dilatation
CAU: Don’t allowavaginal
examinationtominimize placental
trauma
Placenta previa
C: Unknown cause;
associated with
hypertension and
cocaine use; placenta
separates from uterus
before birth of fetus
ABRUPTIO PLACENTA
Show (pink-stained)
vaginal discharge
accompanied by
uterine contractions
becoming regular and
effective
PRETERM LABOR
CAU: Disseminated intravascular
coagulation Is associated with condition
ABRUPTIO PLACENTA
Sharp abdominal pain
followed by uterine
tenderness; vaginal
bleeding; signs of
hypovolemic shock, fetal distress
ABRUPTIO PLACENTA
Preterm labor may be halted
If the cervix is less than 4 cm dilated and the membranes are intact. Corticosteroids are administered to aid fetal lung maturity
PRETERM LABOR
ASSESSING A PREGNANT PT WITH HYPOVOLEMIC SHOCK
Confusion
Pallor
Tachypnea
Increased pulse
Decreased blood pressure
Decreased cardic output
Peripheral vasoconstriction (placenta reacts as a peripheral organ)
Fetal bradycardia
Decreased urinary output
Cold extremities
C: Many possible
etiologic factors such
as trauma, substance
use, hypertension of
pregnancy, or
cervicitis; increased
chane in multiple
gestation, illness
during pregnancy
PRETERM LABOR
SIGNS AND SYMPTOMS OF HYPOVOLEMIC SHOCK
- INCREASED PR
- DECREASED BP
- INCREASED RR
- COLD, CLAMMY SKIN
- DECREASED URINE OUTPUT
- DIZINESS OR DECREASED LEVEL OF CONSCIOUSNESS
- DECREASED CENTRAL VENOUS PRESSURE
