clinical prep Flashcards
IV mag sulfate daily assessments
Neuro check
Assess for s/s toxicity (deep tendon reflexes, respirations, LOC, proteinuria, headache, visual disturbances)
Draw labs/urine check for magnesium levels
Q15-30, BP, respiration rate
Continuous fetal heart rate and contraction monitoring
amniotic membranes ruptured (PPROM)
Greatest risk—Chorioamnionitis
Assess risk—risk factors are meconium-stained amniotic fluid, presence of certain genital tract pathogens, FHR and contraction monitoring
s/s pre-eclampsia
htn (>140/90)
proteinuria
thrombocytopenia: <100,000
impaired liver function: check liver enzymes
renal insufficiency: creatinine
pulmonary edema
cerebral or visual disturbances: new HA unresponsive to meds, no alternative diagnosis
mag toxicity antidote
IV calcium gluconate
nc for preexisting DM
Increased risk for gestational diabetes, high-risk pregnancies
With gestational diabetes, increased risk for preeclampsia, eclampsia, and polyhydramnios
Assess acute and chronic complications of DM, renal function
GBS transmission method
Birth canal
Occurs just before or during labor
GBS prophylaxis
during labor
placental abruption v. placenta previa
Previa = placenta is near or covers the cervical opening
Abruption = placenta detaches prematurely from uterus
cervical insufficiency
Passive and painless dilation of the cervix leading to recurrent preterm births during the second trimester
Often it is abnormally short
cerclage
Treatment for cervical insufficiency d/t cervical weakness
Keeps cervix closed during pregnancy (band or stitch)
non stress test with fetal monitoring
Check for fetal heart accelerations
Use Doppler and tocodynamometer
Reactive NST–HR accelerates to 15 bpm above baseline for 15 seconds in 20 minutes time if over 32 weeks gestation
If under 32 weeks, need above 10 bpm for 10 seconds
Nonreactive NST–accelerations not seen
How is continuous monitoring different from a non-stress test?
only lasts 30 min
Non-stress tests are for at risk fetuses, newborn complications in the past, or prior stillbirths
Necessary follow-up for abnormal findings of non stress test
Non reactive needs further testing: extend 20 min; still non reactive = CST or BPP
biophysical profile
breathing: at least 1 episode for at least 30s in 30 min
movement: at least 3 in 30 min
tone: at least one active extension-flexion
amniotic fluid: deepest vertical pocket >2cm
nonstress: reactive
necessary followup for abnormal findings of BPP
10-8: normal, repeat testing weekly to twice weekly intervals
6: suspect chronic asphyxia, consider proceeding to brith if pulmonary maturity; if not, repeat in 4-6 hr, deliver if oligohydramnios present
4: suspect chronic asphyxia, if >36 wk birth; if <32 wk repeat
0-2: strongly suspect chronic asphyxia extend test to 120 min, if persistent <4, proceed to birth
quad screen
Screen for trisomy chromosomes at 15 -21 weeks, measure levels of 4 maternal serum markers
Necessary follow up for abnormal findings for quad screen?
Genetic counseling and diagnostic testing of trisomy 21 or other chromosome abnormality diagnostics (NIPT)
pathophysiology of anemia during pregnancy
IDA–Excess plasma volume can make hgb look low
Sickle cell
Folic acid deficiency anemia–absence of folic acid so RBCs can’t dive (become enlarged and fewer in number)
s/s anemia
fatigue, pallor, tachy
Sickle cell anemia–sickle cell crisis
Folic acid deficiency–neural tube defect
treatment for anemia
Often don’t treat until iron is below 11
Ferrous sulfate
Sickle cell anemia–prevent crisis with IVF, abx, folic acid, analgesics
Folic acid deficiency anemia–all childbearing women take 400 mcg folic acid before pregnant then 1 mg after pregnant
freq of contraction
time from beginning of one to the beginning of next
contraction duration
time from start of contraction to end of same contraction
intensity of contraction
strength at peak
How is the assessment different when the client has an internal intrauterine pressure catheter (IUPC)?
It is in the uterus; toco is on the stomach
resting tone
Average is 10mmHg; palpate soft and easy
first stage of labor (latent and active)
Latent - cervix effaces, little increase in descent
Active - rapid dilation of the cervix and increased rate of descent of the presenting part
nc for first stage of labor
advocate and communicate her wishes, establish outcomes and expectations, protect modesty and dignity, positive reinforcement
Catheterization, IV, hygiene, intake
(longer table in google doc)
nc during second stage (latent)
Rest and calm
Rest is position of comfort, conserve energy, promote progress of fetal descent and onset of urge to bear down (encourage position changes, pelvic rock, ambulation, showering
nc for second stage active
woman has strong urges to bear down
1:1 nursing care–do NOT leave the woman alone
Help her change position
Help her to relax and conserve energy between contractions
Provide comfort and pain measures
Cleanse the perineum if fecal material is expelled
Coach her to pant during contractions and to gently push when the head is emerging
Provide emotional support, encouragement, positive reinforcement
Keep her informed about the progress
Offer a mirror to watch the birth
Created a calm and supportive environment
Encourage the woman to touch the fetal head when it is visible at the perineum
nc for third stage
Q15 minute assessment of maternal BP, pulse, and respirations
Assess for signs of placental separation and amount of bleeding
Assist with determination of APGAR score at 1 and 5 min of birth
Assess maternal and parter response to completion of birth process and their reaction to the newborn
Assist mom to bear down to expel separated placenta
Hygienic cleaning
Promote skin-to-skin contact with baby and delayed cord clamping
Provide private time for parents to bond with their baby; help them create memories
Massage the fundus
Give pitocin IV infusion after delivery of the placenta to decrease blood loss
dilation
when the cervix begins to open during labor. The cervix starts at 0 (not open) to 10 (complete or all the way dilated)
effacement
thinning of the cervix
The cervix should be 100% effaced before pushing begins
potential hazards when a patient pushes at 9 cm or less
Pain
Head crushed
Prolonged labor
Cervix swells
HR drops
engagement
when the widest part of the baby has passed through the pelvis
station
where the fetus is located in relation to ischial spines
If presenting part is 2 cm above the ischial spines, the fetus is at -2 station.
If presenting part is at the ischial spines, the fetus is at 0 station.
If presenting part is 1 cm below the ischial spines, the fetus is at +1 station
Normal baseline range of FHR
110 - 160
Variability
shows fetal oxygen status in absence of acidosis
Fetal tachycardia
baseline HR >160 bpm lasting >10 min
Fetal tachycardia - causes
interruption of fetal oxygenation, resulting in metabolic acidemia, fetal cardiac arrhythmias, maternal fever, infection (including chorioamnionitis), parasympatholytic drugs, beta-sympathomimetric drugs, maternal hyperthyroidism, fetal anemia, drugs (cocaine, caffeine)
Fetal tachycardia - nc
depends on cause; reduce maternal fever with antipyretics and cooling measures, carry out HCP orders
fetal brady
<110 beats/min lasting >10 min
fetal brady - causes
AV dissociation (heart block), structural defects, viral infections, meds, heart fail, maternal hypoglycemia, maternal hypothermia, interruption of fetal O2
fetal brady - nc
same as late decelerations
accelerations
indicate interruption of fetal oxygenation leading to fetal metabolic acidemia in not occurring at the time they are observed
accelerations - causes
spontaneous fetal movement, vaginal exam, electrode application, fetal scalp stim, fetal reaction to external sounds, breech, occiput posterior position, uterine contractions, fundal pressure, abd palpation
accelerations - nc
none
early decelerations
no known relationship to hypoxemia, clinically benign, not associated with poor outcome
early decelerations - causes
head compression: contractions, vaginal exam, fundal pressure, placement of internal mode of monitoring
