1
Q

Premonitory Signs of Labor

A

Braxton Hicks contraction
Lightening
Increase in clear and non-irritating
Vaginal secretions
“Bloody Show” -> cervical mucos w/ pink tinge ( 2 wks b/4 plugs pop out)
Energy spurt/ nesting (2 wks)

Q

True Labor

A

Pain in lower back radiates to abdomen
Pain accompanied by reg rhythmic contractions
Contractions that intensify w/ ambulation
Progessive cerivcal dilation and effacement

Q

False Labor

A

Discomfort localized in abdomen
NO lower back pain
Contractions decrease in intensity or frequency w/ ambulation
Cerivx doesn’t change

Q

Components of the birthing process (5 Ps)

Power

Contractions

A

Uterine contractions (myometrium layer) and maternal pushing effort
* strength/intensity (lay hands on abd, feel if its hard as forehead)
* Duration → how long the contractions last (45
* Frequency → beginning of one contraction/beginning of the next

Q

Passage

A

True pelvis → position through which the baby must travel
3 planes:
* Pelvic inlet
* Mid pelvis → ischial spines ( 0 -> engaged)
* Pelvic outlet

gonocid is the right shape

Q

Passenger

Fetus

A

Molding ( makes baby head smaller to fit)
Attitude → flexion of the baby’s neck
Presentation → what’s presenting to the outlet first
PositionROA/LOA/ROP/LOP for cephalic presentation
Fetal lie → baby’s spine r/t mother’s spine
* Longitudinal is most common
* Transverse
Situation
**Engagement **→ 0 station
**Station **→ relationship of the presenting part to the ischial spines
-4: the baby’s head hasn’t entered the pelvis (ballotable)
+4: the baby is crowning (HOP)
Engagement → largest part of the baby has “engaged” or passed through the most narrow part of the mom’s pelvis
* 0 station
* Typically primigravida (first pregnancies) engage around 38 weeks

LOA is most common followed by ROA

Q

Psyche

Maternal responses

A

Birth affects the whole way a woman thinks of herself
Lasting effects
Postivie birth experience (role of the RN)
* Clear information
* Positive support
* Breathing exercising and other aspects of the birth that she can controls

Q

Latent Phase

A

beginning of true of labor until 3-4 cm
Mild contractions
Able to speak, smile, talk with family/caregiver
Hard to predict how long it will last
Assess uterine contractions every hour
Assess maternal vital signs every hour
Temp is taken every 2 hours once ROM
Assess FHR every hour

6-9 hours for nulliparous, less for multipar

Q

Active Phase

A

4-7 cm
Strong active contraction
“Serious” about labor vs. earlier joking around
Maternal VS, FHT and uterine contractions assessed every 30 minutes
N/V is common in this stage
Hyperventilation d/t discomfort can lead to respiratory alkalosis → help the patient calm down/slow breathing
Can use brown paper bag for this

Q

Transition Phase

A

8-10 cm
Maternal VS every 15 minutes
Assess FHR and uterine contractions every 15 minutes
Shortest but very intense ( 10 min -1hr)
May feel “pushy” /usually very IRRITABLE
Urge to push → Ferguson reflex
* Don’t allow patient to push unless FULLY dilated
* Full bladder can impede labor, contractions are then ineffective and labor can be longer b/c of this

Q

Leopold’s Maneuvers

A

used to determine fetal position
Preference for baby in a flexed position
Landmark on the baby’s body
Occiput (back of head) sacrum (buttocks) most common
Assessment of FHR and pattern
* Check FHR tones if pt thinks membranes have ruptured
Assessment of ROM → nitrazine test/tfern test
* Assess amniotic fluid under microscope → assess if fern-like pattern is present
* Check color → should be clear or brown (w/ meconium)
Blood is ABNORM
There should be NO odor (this would mean infection)

Q

Stage 2

A

10 cm to delivery
Involuntary urge to push
Gravity is best for fetal descent (squatting)
1 hour for nulliparous, 15 minutes for multipara
Usually will not allow the mother to push more than 2-3 hours
Assess FHR and uterine contractions every 15 minutes
Assess maternal VS every 5-15 minutes

Q

Stage 3

A

Delivery of Placenta
d/c oxytocin if in use until after placenta is delivered
* Admin after delivery
* Perform fundal massage after placenta

Pushing and birth

17
Q

Stage 4

A

**First 1-4 hours following delivery **
Recovery phase
Gentle cleanse perineal area
place crushed ice or cold peri-pack on perineum
Breastfeeding for the first 30 mins of life
Uterine stimulants → common drugs used to promote uterine contraction and control postpartum bleeding
* Oxytocin (pitocin) → 10-20 units IV or IM
* Methylergonovine maleate (methergine) 0.2 mg IM or PO
DO NOT give to patients w/ hypertension d/t its vasoconstrictive action
* Carboprost (Hemabate) 0.25 mg q 15-90 minutes (up to 8 doses)
DO NOT give to patients w/ asthma

Never give uterine stimulants before delivery of the placenta
Assess for bladder distention → full bladder is one of the most common reasons for uterine atony or hemorrhage in the first 24 houes after delivery
Maintain bed rest for 1 -2 hours to prevent orthostatic Hypotension if epiduralized
Immediate PP assessments → include maternal VS, fundal assessment, lochia assessment

18
Q

Vaginal exams

A

Performed throughout labor
Baseline vaginal exam upon admission
Client in modified lithotomy position
Sterile gloves are worn
Restricted once ROM has occurred
* Once membranes are ruptures, limit vaginal exams
