25
Relationship of the presenting part of the fetus (sacrum, mentum, or occiput) preferably the occiput, in reference to its directional position as it relates to one of the four maternal pelvic quadrants.
Fetopelvic or Fetal Position
26
Uterine contractions cause effacement and dilation of the cervix and descent of the fetus. Involuntary urge to push and voluntary bearing down in the second stage helps in the expulsion of the fetus.
Powers
27
"The Birth Canal" which is composed of the bony pelvis, cervix, pelvic floor, vagina, and introitus (vaginal opening). The size and shape of the bony pelvis must be adequate to allow the fetus to pass through it. The cervix must dilate and efface in response to contractions and fetal descent.
Passageway
28
The client should engage in frequent position changes during labor to increase comfort, relieve fatigue, and promote circulation. Position during second stage is determined by maternal preference, primary care provider preference, the condition of the mother and the fetus.
Position of Laboring Woman
29
Maternal stress, tension, and anxiety can produce changes that impair the progress of labor.
Psychological Response
30
Bony Pelvis

31
Involuntary uterine contractions that signal the beginning of labor
Primary Powers
32
Once the cervix has dilated voluntary bearing-down efforts by the woman that augment the force of the involuntary contractions
Secondary Powers
33
Two contractions without returning to the baseline. This is an ominous sign.
Coupling
34
Measured from the beginning of one contraction to the beginning of the next or from the peak of one to the peak of the next
Frequency
35
The beginning of one contraction to the end of the same contraction
Duration

Signs of Preceding Labor
Lightening (baby dropped) Bloody show Maternal weight loss Surge of Energy
39
May be spontaneous or by amnotomy
Rupture of Membranes (ROM) | ****Assess FHT immediately after ROM
40
Indications of Imminent Delivery
Bulging of perineum Uncontrollable urge to bear down Sudden increase in bloody show - May accompany urge to bear down
41
Phases of Stage 1 of Delivery
Latent Active Transitional
42
Cervical Dilation 0 to 3-4 cm Effacement - Beginning to 50% Contractions - regular, q 15-30 min, mild-moderate intensity lasting 15-30 sec Presenting part -3 to 0 station Bloody show may be present Mother may feel anticipation, excitement and be talkative and able to cope
Latent Phase
43
Cervical dilation - 4 to 7-8 cm Effacement 50 to 100% Contractions regular q 3-5 min x 30-60 sec with moderate intensity Presenting part +1 to +3 station Increased bloody show Mother becomes serious, concerned about progress of labor, and may ask for pain meds
Active Phase
44
Cervical dilation - 8 to 10 cm Effacement - 100% Presenting part continues descent Heavy bloody show Spontaneous rupture of membranes (SROM) - monitor FHR after ROM*** Mother less able to cope, may become angry, may lose control, thrash about in bed, groan or cry, may develop n/v, leg tremors
Transitional Phase
45
From complete cervical dilation through delivery of infant. Maternal behavior changes to actively pushing but may become exhausted In order to assist the client with pushing tell the client to take 2 cleansing breaths and push When the client is crowning the doctor is called and delivery is accomplished The nurse is responsible for prepping the perineum for the delivery
Stage 2
46
From delivery of infant through delivery of placenta. May experience due to uterine contractions before expulsion of placenta The doctor will deliver the placenta and examine the client for retained placenta The sign of release of the placenta -Lengthening of the umbilical cord in the vagina -Gush of dark blood -Globular shaped uterus Usually within 5-7 minutes after birth of baby
Stage 3
47
``` 1-4 hours following delivery Uterus should remain firm and positioned at midline, 1-2 finger breadths below umbilicus. Mother usually excited and tired, may be hungry or drowsy Assess -VS -Lochia (Bloody discharge after delivery) -Apply ice to episiotomy -Massage fundus -Check bladder Prevent hemorrhage -Massage fundus -Administer oxytocin -Keep bladder empty -Monitor VS ```
Stage 4
48
7 Cardinal Movements
``` Engagement Descent Flexion Internal Rotation Extension External Rotation Birth by Expulsion ```
49
Occurs when the presenting part passes the pelvis inlet at the level of the ischial spines. Referred to as station 0
Engagement
50
The progress of the presenting part through the pelvis
Descent
51
When the fetal head meets resistance of the cervix, pelvic wall, or pelvic floor, THe head flexes bringing the chin close to the chest, presenting a smaller diameter to pass through the pelvis
Flexion
52
The fetal occiput ideally rotates to a lateral anterior position as it progresses from the ischial spines to the lower pelvis in a corkscrew motion to pass through the pelvis
Internal Rotation
53
The fetal occiput passes under the symphysis pubis and then the head is deflected anteriorly and is born by extension of the chin away from the fetal chest
Extension
54
After the head is born it rotates to the position it occupied as it entered the pelvic inlet in alignment with the fetal body and completes a quarter turn to face transverse as the anterior shoulder passes under the symphysis
External Rotation
55
After birth of the head and shoulder the trunk of the infant is born by flexing it toward the symphysis pubis
Birth by Expulsion
56
Fetal Adaptation to Labor
Heart Rate (Accelerates and Decelerates) Circulation Respiration (Pg. 390)
57
Maternal Adaptation to Labor
Every system is affected (look at diagram of women)
58
Assessment of the laboring patient
``` Birth Plan: -Childbirth techniques; attended classes? -Support -Analgesia; Anesthesia Prenatal History: -EDC -Lab -Previous Experiences -Risk Factors ```
59
Assessment
``` Urine VS Connect to Monitor Uterine Contractions FHR-rate, variability, periodic changes Vaginal Exam (must be done sterile) Temp q2h if ROM ```
60
Vital Signs
Epidural: -BP q min x 5 min, then q5min, then q15min until stable as ordered Active Labor: - q 15-30 min -q 15 min during transition Take the temp q2hr - if PROM be vigilant in checking the VS and for signs of infections
61
Induction of Labor
Pitocin (Oxytocin) - used to induce labor (Protocol when membranes intact): - Pitocin 30 units in 500 ml NS for induction - IVPB into primary IV - Begin at 3 milliunits/minute via infusion pump - May increase to 5 milliunits/minute after 15 minutes - Never exceed 20 milliunits unless MD orders * **ALWAYS ON PUMP***
62
From cervical changes, distention of lower uterine segment, and uterine ischemia Located over the lower portion of abdomen Referred pain: originates in uterus, radiates to abdominal wall, lumbosacral area of back, iliac crests, gluteal area, and down the thighs
Visceral Pain
63
Pain described as intense, sharp, burning, and well localized Stretching and distention of perineal tissues and pelvic floor to allow passage of fetus, from distention and traction on peritoneum and uterocervical supports during contractions, and from lacerations of soft tissue
Somatic Pain
64
Threshold remarkably similar in all, regardless of gender, social, ethnic, or cultural differences Differences play definite role in person's perception of and behavioral responses to pain
Perception of Pain
65
Pain results in physiologic effects and sensory and emotional (affective) responses Emotional expressions of suffering often seen
Expression of Pain
66
Nonpharmacologic Management of Discomfort
Relaxing and breathing techniques: - Relaxation - Imagery and visualization - Music - Touch and massage - Breathing techniques - Effleurage and counter pressure - Water therapy (hydrotherapy)
67
Medications for Pain (Analgesia)
Demerol/Fentanyl Stadol/Nubain (IVP) -Push at the beginning of the contraction*** -May be used because these do not depress respirations or cause fetal depression -If given to a drug addicted client may cause narcotic withdrawal
68
Epidural Anesthesia
Put in at about 4 cm The nurse is responsible for vital signs -BP (Monitor drop in BP immediately following epidural), R, FHT's, etc.. *For Epidural/Spinal Anesthesia the client is given a bolus of IV fluid to offset the fluid volume deficit**
69
If the BP drops...
Open plain IV fluid Turn client to the side Apply oxygen by tight face mask at 10-12 L/min Elevate feet (don't put head down below 35 degrees) *If FHT's go down may need to turn off Pitocin*
70
An abnormal, dysfunctional, or difficult process of labor resulting primarily from ineffective uterine contractions, fetal problems or pelvic inadequacy
Dystocia
71
Thin, Watery (light brown)--no treatment Thick peas soup like--Indicates that the fetus has been stressed or in distress -Delee suction @ birth before first breath -Suction through ET tube with meconium aspirator
Meconium Stained Amniotic Fluid
