25
placenta previa: complete
the placenta completely covers the cervix
26
placenta previa: partial
the placenta partially covers the cervix
27
placenta previa: marginal
placenta is near the cervix low lying
28
placenta previa: low lying
low lying **fairly close to cervix but not touching it**
29
placenta previa nursing care
-**no vaginal exams** -assess for bleeding (active = transfusion) -VS & fetal monitoring & contractions -anticipate unengaged fetal presenting part (transverse lie is common) -obtain consent for C section ICE -administer tocolytics as ordered
30
abruptio placentae
premature separation of a normally implanted placenta from the uterine wall
31
abruptio placentae: marginal
placenta separates at its edges
32
abruptio placentae: central
placenta separates centrally -> concealed bleeding **hard abdomen where blood is pooling**
33
abruptio placentae: complete
total separation -> massive vaginal bleeding
34
abruptio placentae: grade 1
48% mild separation, slight vaginal bleedingV
35
abruptio placentae: grade 2
27% partial abruption with moderate bleeding
36
abruptio placentae: grade 3
24% complete separation with moderate to severe bleeding
37
abruptio placentae S/s
-sudden & stormy onset -bleeding is external or concealed -blood is dark -severe & steady pain, uterus is tender -uterine tone is firm
38
placenta previa S/s
-quiet & sneaky onset -external bleeding -blood is bright red -pain only present at labor, uterus is not tender -uterine tone is soft & relaxed
39
abruptio placentae care
-external monitoring of contractions -external monitoring fetus -monitor for c/o abdominal pain -monitor for development of DIC (coag test) -immediate priorities are maintaining maternal cardiovas status -C section is usually safest delivery
40
maternal and fetal risks of multiple gestations
PLT uterine dysfunction abnormal fetal presentations instrumental or C section PP hemorrhage higher mortality rate than for single fetus decreased intrauterine growth rate increased incidence of fetal anomalies increase in cord accidents increase in cerebral palsy
41
multiple gestations: discomforts
-SOB / dyspnea on exertion -bachache -round ligament pain -heartburn -pelvic or suprapubic pressure -pedal edema
42
multiple gestation: comfort measures
-side lying position w/ lower body elevated -pelvic rocking -good posture -good body mechanics
43
multiple gestation: care
-more frequent visits & educate on signs of fetal activity and preterm labor -serial ultrasounds -anesthesia & cross match blood ready @ delivery -dual monitoring -likely choose c section
44
multiple gestation: nutrition
-prenatals -daily folic acid intake of 1mg -wt gain of 40-45 lbs (24 lbs gain by wk 24)
45
amniotic fluid embolism
amniotic fluid leaks into the maternal circulation through a small tear in the amnion or chorion of the uterus during placental separation or through cervical tears under pressure -> embolism blocks vessels of the lungs **rare but 80-90% mortality rate**
46
amniotic fluid embolism S/s
chest pain, dyspnea, cyanosis, frothy sputum, tachycardia, hypotension, massive hemorrhage
47
amniotic fluid embolism: care
-stabilize cardiovascular & res system -**displace uterus to allow better blood flow** -infusion of whole blood -placement of central venous pressure line to monitor fluid overload -immediate birth may be needed
48
dysfunctional labor patterns: hypertonic contractions
tachysystole -> more than 5 contractions in a 10 min time period
49
dysfunctional labor patterns: hypotonic contractions
fewer than 2-3 contractions in 10 minutes (low intensity contractions)
50
tachysystole care
-assess contractions, vitals & FHR -comfort measures -change positions & back rubs -turn off oxytocin -tocolytic -sedation / pain meds
51
care for hypotonic contractions
-assess contractions, vitals & FHR -consider cephalopelvic disproportion -rule out malpresentation -maintain adequate hydration -monitor for signs of infection -stimulation of contractions (oxytocin)
52
post dates
pregnancy has gone beyond estimated date of birth
53
post term
pregnancy has gone beyond 42 completed weeks
54
care for post term pregnancies
-assess fetal well being -daily fetal movement counts -NST -biophysical profile -induction of labor
55
maternal risks for post term pregnancy
-perineal damage -hemorrhage -increased risk of C section -anxiety -emotional fatigue -persistence of normal discomforts
56
fetal risks for post term pregnancy
-decreased perfusion -oligohydramnios -SGA -macrosomia -increase risk for meconium stain ed fluid
57
malposition (OP) techniques to move baby
-mother rotates side to side -knee to chest position -hands and knees position -physician / CNM may manually rotate fetal head during labor
58
malpresentation
-shoulder presentation -brow presentation -face presentation -breech
59
version
turning of the fetus in utero
60
version: external cephalic version
external manipulation of maternal abdomen to change fetus from breech to cephalic position
61
version: podalic version
internal used in delivery of 2nd twin
62
if a version is about to happen, what must be done
-pt signs consent to procedure & c sections + -IV is in place -ultrasounds -terbutaline if contracting -fasting for 8hrs -fetal monitoring (w/ reactive NST) -rhogam if pt is Rh negative
63
reasons for a non reassuring fetal status
-variation in HR -decreased fetal movement -meconium stained amniotic fluid -persistent late decels -persistent severe variable decels
64
umbilical cord prolapse
umbilical cord precedes presenting fetal part and is compressed against maternal pelvis
65
how to prevent umbilical cord prolapse
bed rest if fetal presenting part high in pelvis & amniotic fluid is ruptured
66
if umbilical cord is felt during vaginal exam, what do you do
**keep gloved fingers in vagina to relieve pressure** & position for gravity to help relieve compression (knees to chest or trendelenburg) -> apply O2 mask & prepare for C section
67
is baby has true cephalopelvic disproportion (CPD), how should baby be delivered
can use vacuum or forceps assessed vaginal birth but best practice is **C section**
68
fetal risk for CPD
-increased risk of cord prolapse -excessive molding of fetal head -bruising -nerve trauma
69
macrosomia
large fetus weighing more than 4000 grams
70
macrosomia risks
-dysfunctional labor -uterine rupture -perineal lacerations -postpartum hemorrhage -should dystocia
71
when do you want to ID macrosomia
before labor begins
72
if cleared for vaginal delivery with a macrosomia baby, what should the nurse be prepared for
-lack fetal descent should raise suspicion that infant is too large for vaginal birth -unexpected shoulder dystocia, may be asked to assist w/ McRoberts maneuver or apply suprapubic pressure to aid shoulder delivery **never perform fundal pressure**
73
shoulder dystocia
shoulders entrapped behind suprapubic bone
74
dangers of shoulder dystocia
-brain damage from hypoxia -brachia plexus damage -umbilical cord occlusion
75
interventions of a shoulder dystocia
-lower head of bed -McRoberts maneuver (rotate legs up and out to open pelvis) -suprapubic pressure (downward w/ hand) -document interventions & length of time of dystocia
76
retained placenta
retention of placenta beyond 30 mins after birth, bleeding can be excessive & may require manual removal of placenta -> possible transfusion after depending on blood loss **increased risk for infection**
77
lacerations
-spontaneous tearing of the perineal area -suspected when bright red vaginal bleeding persists despite well contracted uterus - 1 to 4 degrees - assist w. 4th stage labor repair and observe for bleeding and approximation during PP
78
placenta: accreate, increta / percreta
-abnormal adherence of the placenta to the uterine wall -associated w/ maternal hemorrhage & failed placental separation after birth **high incidence of abdominal hysterectomy**
79
placenta accreta
chorionic villi attach directly to the uterine myometrium
80
placenta increta
myometrium is invaded
81
placenta percreta
myometrium is penetrated -sometimes attaches to nearby organs like the bowel or bladder
82
where does the placenta usually connect to
the endometrium
83
placenta accreate, increta / percreta care
-monitor for bleeding -deliver before 38 wks -type & cross for blood transfusion -2/3 women have hysterectomy to prevent maternal hemorrhage -repair organ damage
84
if a baby is lost in utero, what organization always has to be consulted
KODA for organ donation
