Q

placenta previa

A

implants in lower uterine segment, when in c and dilates, placental villi are torn from uterine wall -> bright red painless bleed

complete= cover cervix; partial = partial; marginal = near cervix; low lying = close
need c/s for complete and partial
vaginal possible for marginal (high risk) and low lying

Q

abruptio placentae: nc

A

maintain maternal CV status!!!!
EFM and toco, c/o abd pain, abd girth, DIC dev (coag tests), c/s safest

22
Q

placenta previa s/s

A

quiet and sneaky onset, external bleed, bright red, anemia and shock = to blood loss, labor pain, no uterine tenderness - soft and relaxed with normal contour, FHT usually present, not engaged, may have abn presentation, no toxemia

23
Q

apruptio placentae s/s

A

sudden and stormy onset, external or concealed bleed, dark venous blood, anemia and shock greater than apparent blood loss, may have toxemia, pain is severe and steady, uterine tenderness present - firm to stony hard and contour may enlarge or change chage, FHT present or absent, engagement may be present, no relationship to presentation

24
Q

multiple gestation: r

A

preT, uterine dysfunction, abn fetal presentations, instrumental or c/s, PPH, increased mortality, decreased IUG rate, increased fetal anomalies, more cord accidents, increased cerebral palsy

25
multiple gestation: discomforts
SOB, doe, backache (pelvic rock, good posture and body mechanics), round ligaments pain, heart burn, pelvic or suprapubic P, pedal edema freq rest (side lying, legs and feet up)
26
multiple gestation: nc
more freq visits educate: nutrition (vits, 1mg folic acid/day, 40-45 lb with 24 + by 24 wk), fetal activity, s of preterm labor serial US anesthesia and cross matched blood available, continuous dual electronic fetal monitoring, delivery method may change (fetal position), c/s maybe
27
amniotic fluid complications
600-1000mL (AFI 5-25 cm is normal) hydraminos: preT, amniocentesis to remove oligohydraminos: renal and urinary malformations, skin and skeletal abn, pulomary hypoplasia, cord compression
28
amniotic fluid complications: amniotic fluid embolism
anaphylactoid S leaks into M circulation via tear in amnion or chorion of uterus during placental separation or cervical tears under P from c, blocks vessel of lungs rare, high mortality
29
amniotic fluid complications: amniotic fluid embolism - s/s
chest pain, dyspnea, cyanosis, frothy sputum, tachy, hypoT, hemorrhage
30
amniotic fluid complications: amniotic fluid embolism - nc
stabilize CV and R system displace uterus during CPR, infused whole blood, place CVP to monitor for fluid overload, maybe immediate birth
31
dysfunctional labor pattern
dystocia - abd fetal presentation hypertonic c: tachysystole, >5c in 10 min (q2 min); assess FHR, c, VS, comfort and support, change position, backrubs, no oxytocin, tocolytic, sedation, pain med hypotonic c: <2-3 c in 10 min, low intensity; assess FHR, C, VS, consider CPD, rule out malpresentation, maintain adequate hydration, s/s infection, stim uterine C (oxytocin)
32
post term
>42 wk, post date = >EDB assess fetus, daily movement, NDT BPP, induce (monitor fetal response)
33
post term: M impacts
perineal damage, hemorrhage, increased risk of c/s, anx, emotional fatigue, persistance of normal discomforts
34
post term: F impacts
decreased perfusion, oligoH, SGA (small), macrosomia, increased risk of meconium stained fluid and meconium aspiration S
35
malpresentation
shoulder, brow, face, breech (frank, complete, footling)
36
malposition
persistent OP position, rotate side to side, knee-chest, hands knee, physician or CNM may manually rotate fetal head during labor
37
malposition/malpresentation: version
turn fetus in utero ECV = external manipulation of abd to change cephalic podalic (internal) = deliver 2nd twin, less common; care: c/s consent, US, IV access, terbutaline, if c, fast 8hr before, fetal monitor before, during ,after, reactive NST, prophylactic rhogam if -
38
nonreassuring fetal status
UNCOIL variation from normal HR (brady or tachy), decreased FM, meconium stained amniotic fluid, persistent late decels, persistent severe variable decel
39
umbilical cord prolapse
precedes presenting part and is compressed against maternal pelvis prevent! bed rest of presenting part high in pelvis and ROM if cord noted in exam, keep fingers in to relived P knee chest or trendelenberg -> gravity relives P o2 10L /tight face mask prep for c/s
40
CPD
true = deliver via c/s maternal R: prolonged labor, increased risk of uterine rupture, forceps assisted or vacuum, c/s fetal R: increased risk of cord prolapse, excessive molding of fetal head, bruising, nerve trauma
41
macrosomia
>4000g r: dysfunctional labor, uterine rupture, perineal lacerations, PPH, shoulder dystocia
42
macrosomia nc
identify before labor, eval pelvis, estimate size with US c/s possible vaginal: lack of fetal descent (increased suspicion - too large), shoulder dystocia = critical problem, McRoberts or apply suprapubic P to help with back of shoulders, no fundal P
43
shoulder dystocia
entrapped behind suprapubic bone danger = brain damage - hypoxia, brachia plexus damage, umbilical cord occulssion lower HOB, McRoberts (legs up and out), suprapubic P, doc interventions and L of dystocia
44
3rd and 4th stage complications
retained placenta, lacerations, placental delivery issues
45
retained placenta
>30min excessive bleed, manual removal, transfusion Increased r/o subinvolution, infection, bleeding
46
lacerations
spontaneous, bright red blood persist with well contracted uterus observe for bleed and approximation during PP
47
placenta issues
abn adherence to uterine wall hemorrhage and failed placenta separation, increased incidence of abd hysterectomy rf: placenta previa, previous uterine sx, endometrial defects, age and parity, increased c/s
48
placenta issues: types
accreta: chorionic villi attache directly to uterine myometrium increta: myometrium invaded percreta: myometrium penetrated, attach to nearby organs (bowel/bladder)
49
placenta issues: nc
monitor for bleed close to delivery, deliver before 38, type and cross blood, abd hysterectomy to prevent hemorrhage, repair organ damage
50
perinatal loss
denial, anger, bargaining, depression, acceptance nc: prep for birth and death (counselor, chaplain), support decision, view/hold infant (actualize loss, picture, membox, mementos, baptism, burial), PP care, d/c care, referrals, KODA I am sorry for your loss, how can I help, listen, acknowledge the baby was special and loved dont say: you can get preg, have another, for a reason, grateful for what you have, i know how you feel
51
s of infection
FHR and MHR increase, fever
