WEEK 7 Flashcards
Labor ATI Pain Management ATI
presentation of fetus in labor
refers to the fetal part entering the pelvis of the pregnant client during labor
what happens during sterile digital examination of
the presenting part is palpated, assessing the location of fontanels and other palpable landmarks. Suture lines of the fetal skull will be palpable when the fetus is in a cephalic presentation
suture lines
Areas of dense connective tissue between fetal skull bones.
what is the fetal presentation during an uncomplicated labor
cephalic presentation
cephalic presentation
Fetal head is the part that presents down toward the birth canal.
Less common presentations during labor
breech
shoulder
compound
breech
The fetal buttocks, feet, or knees present in the maternal pelvis first.
shoulder presentation
The fetal shoulder is the lowermost part of the fetus during labor.
compound presentation
common, hand over face and you would feel fingers when you do an exam
descriptions of presentation
right occiput anterior (ROA), left occiput anterior (LOA), right occiput posterior (ROP), and left occiput posterior
fetal lie
position of the fetal long axis (fetal spin) related to the maternal spine
what is the most common fetal attitude
head down, chin to chest: good because it puts the crown of the head coming out (it can sustain the pressure)
primiparous clients and maternal structure
(client who is experiencing a first pregnancy lasting to at least 20 weeks of gestation)
They may have a most taut pelvic passage that may be more taut, which can be hard for baby to rotate through the birth canal
5 P’s of labor

Position
Psyche
how should contractions be during labor
contractions should become more frequent and stronger as they go on
during labor, the client may need to assume multiple positions, such as
semi-prone recumbent position, hands and knees, standing, or lunging, to change the shape of their pelvis and assist the fetus to rotate into a favorable position.
how to support client in labor when they are tired from pushing?
give good feedback
tug-a-war (the nurse will hold one side the client will pull the nurse towards them and helps push the pelvis)
manifestations signifying labor
decrease in pressure on diaphragm (lightening)
increase in vaginal discharge
mucous plug formed during preg may be expelled due to cervical softening
burst of energy (sometimes referred to as nesting)
what might mucous plug drainage look like
tinged with a small amount of blood and is referred to as bloody snow
why do irregular uterine contractions manifest during early labor
cervix is ripening
During labor and birth, the uterus
contracts to expel the fetus
what part of the uterus is responsible for producing labor contractions
myometrium
true labor contractions
May start in the lower back and lower abdomen and cause pressure in pelvis
May feel like intense menstrual cramps
Get closer together and stronger as time passes
false labor contractions (Braxton Hicks)
May feel like mild menstrual cramps
Often uncomfortable, but not painful
Typically stop with rest
Don’t affect the client’s ability to walk, talk, or progress with normal activities
cardiovascular and hematologic system during labor and delivery
increase blood volume, CO, SV, HR that resolves between contractions
what cell is increased (expected) during pregnancy
lymphocyte values (WBC) as part of the immune system’s response to the physiological stress of pregnancy and labor
so this may hinder identifying infections so other methods besides testing blood will need to be used
GI system during labor (expected)
pain can contribute to delayed gastric emptying and increase N/V
what can a delay in gastric emptying lead to
increased risk of aspiration
Because of this increased risk, clients will often follow a clear-liquid diet during labor and birth that includes ice chips, tea or coffee, hard candy, popsicles, clear broth, fruit juice, flavored gelatin, and carbonated beverages upon provider recommendations
when might clients experience nausea during labor
RAPID cervical dilation or RAPID fetal descent
Renal system during labor
mild incontinence as the fetus places pressure on bladder
proteinuria (HTN clients OR normal BP clients)
why would clients during labor with normal BP have proteinuria?
increase CO and glomerular permeability, labor stress, and decreased renal tubular protein reabsorption
Endocrine system during labor
cortisol levels SURGE
progesterone is present (relax uterus)
increase in estrogen to progesterone ratio
maternal hypothalamus produces oxytocin
Reproductive system during labor
uterus will stretch
dilation and effacement of cervix
contractions lead to fetal descent
what is the BEST position for fetus during labor
anything ending with OA
what happens during labor process to fetus
adapts
changes positions
subject to compression (cone head: HR goes down)
how can the fetus become transiently hypoxic during labor
oxygen-rich blood flow is shunted away from placenta into maternal circulation during each contraction
but Blood flow then returns to the uterus during the relaxation period between contractions, allowing for oxygen delivery to the fetus.
can a normal healthy fetus tolerate transient hypoxia
yes
how would a fetus respond to stressors like hypoxia or infection?
passing meconium into amniotic fluid
greenish discharge of AF from mom
when should babies pass meconium
AFTER BIRTH shouldn’t be in utero,
if it is, there may be an issue
what can happen when there is meconium in amniotic fluid
increase risk for fetal aspiration
increase risk for infection
when mom gets increase CO and increase O2 consumption, where does it go?
placenta which is good
cervical dilation
OPENING of cervix (0-10 cm)
closed: can’t get a finger through
open: can touch baby
cervical effacement
THINNING of the cervix (%)
thinner means closer to having a baby (high % because it is more open and spreading)
how to shorten the first stage or labor
incorporate walking and standing into the plan of care
birth settings
health care facilities
home
birthing centers
Clients will often report to health care facilities with manifestations of labor, including
frequent contractions
fluid leakage
vaginal bleeding or blooding show
what to do with client presenting with manifestations of labor
vital signs (for hemorrhage, preeclampsia, temp)
ask how strong, frequent, duration of contractions if they are presenting with them
Assessment: History and Physical
review prenatal history
med/surg history
previous lab results
preform physical assessment
Assessment: Uterine Contractions
manual palpation (not great, subjective)
TOCO
IUPC
uterine contractions: manual palpation
not great, subjective
but can tell you the difference between contracting or just having uterine hyperstimulation
uterine contractions: tocodynamometer
TOCO
external sensor on fundus and secure with stretchy belt
it does NOT measure contraction strength accurately
when done accurately, records contraction frequency and duration and allows the nurse to compare uterine activity with concurrent FHR patterns
measures DURATION AND FREQ BUT NOT STRENGTH
uterine contractions: intrauterine pressure catheter (IUPC)
Inserted vaginally into the uterus (only done if TOCO is not recording right)
the amniotic membranes MUST be ruptured to do this
what clients usually have more unsatisfactory contraction tracing
obese
what has to happen for IUPC to be in place
amniotic membranes have the be ruptured
what can happen if the uterus is contracted for a long time
uterine rupture
contraction frequency
assess the number of contractions within a 10 minute window
why is a rest period between contractions essential?
during contractions, the blood flood in shunted to baby, so hypoxia occurs, but a break would allow baby to get some blood flow to prepare for next contraction
expected uterine contractions
five or fewer contractions in a 10-minute period, averaged over 30 mins
tachysystole uterine contractions
More than five contractions in a 10-minute period, averaged over 30 minutes
can lead to SEVERE fetal hypoxia
define FREQ of contactions
beginning of one to the beginning of the next
dilation exam
using sterile glove and lube, nurse puts two fingers into the vaginal canal and locates the cervical os
If only one finger can be inserted into the cervical os, the dilation is approximately 1 centimeter. When the cervix is 10 centimeters dilated, the fetal presenting part will be palpable in front of the cervix so that the cervix is no longer palpable
The client giving birth has entered the second stage of labor once they are
10 centimeters dilated
fetal station
the fetal position within the maternal pelvis related to the maternal ischial spines, bony prominences within the pelvis.
- means high up (further away from vag os)
0 neutral
+ means about to PLUS another soul into the world, so close to delivery
5/80/-1 (define this)
5 cm dilated
80% effaced
-1 fetal station (1 cm ABOVE ischial spines of mom PELVIS)
what may PROVIDERS do if in active labor and membranes haven’t ruptured?
amniotomy (Artificial rupture of the amniotic membranes)
what is done upon rupture of membranes?
amniotic fluid is assessed for…
color
odor
consistency
amount
amniotic fluid is expected to be
odorless or have a slight musty odor, have a thin watery consistency, and be clear or straw-colored
vernix
cheese-like protective substance on fetal skin
think from clinical vaginal birth
what to assess after membranes are ruptured
assess client temp IMMEDIATELY and every 2 hrs til birth because the amniotic sac is protection against infection and it has ruptured
temp of mom
fetal tachycardia
uterine tenderness with palpation
foul-smelling vaginal discharge
elevated maternal HR and RR
who usually tells us something is wrong during labor
baby
nitrazine paper
test pH of amniotic fluid
pH between 7.1-7.3
important prenatal labs
blood type and Rh factor
HIV
hep B
CBC
rubella
STI screenings
Group B strep testing
recommended for all preg clients between 36 07-37 6/7
vaginal/rectal swab
if it is + treat with antibiotics
it is not an STD, it does not affect mom only affects baby
nonpharmacological interventions for pain during labor
massage
position changes
submersion into water or birthing tubs (think London OB and the jets tub)
nutrition during labor
clear liquid diet
IV fluids
urine output monitored to assess hydration status
positioning during labor: what position to avoid
avoid supine position due to the risk of supine hypotension and potential FHR decelerations
Leopold Maneuvers
should be preformed prior to FHR assessment
steps:
palpate fundus
palpate each side of abd to determine fetal spine
palpate pubis bone for fetal presentation
palpate abd above pubic bone to determine fetal presentation IN THE MATERNAL PELVIS
intermittent auscultation
for clients with low risk for labor complications
EXTERNAL auscultation during labor (not continuous so not on all the time, done in intervals)
FHR with handheld Doppler every 15-30 mins
