| Four Ps: Components of the Birth Process | Powers. Passage. Passenger. Psyche. |
| Four Ps: Components of the Birth Process: Powers | Involuntary uterine contractions : Primary powers: Responsible for effacement and dilation of the cervix. Secondary powers: Bearing down efforts of the woman which add to the power of the expulsive forces but have no effect on cervical dilation. |
| Four Ps: Components of the Birth Process: Passage. | Bony pelvis and the soft tissues of the pelvis and perineum. |
| Hypertonic (tachysystole) contractions | Less than 2 mins apart. Longer than 90-120 secs. Intervals shorter. Incomplete relaxation of the uterus. Report immediately |
| Four Ps: Components of the Birth Process: Powers:The Psyche | Crucial part of childbirth. Marked anxiety and fear decrease a woman’s ability to cope with pain in labor. Catecholamines inhibit uterine contractions and divert bloodflow from the placenta |
| How are dilation and effacement estimated? | Effacement is the thinning of the cervix, described as a percentage of the original length of the cervix from 0 -100%.. Dilation is the enlargement or widening of the opening of the cervix and the cervical canal from 1cm – 10 cm. |
| What is used to describe how the head is oriented if the fetus is head down? | Fetal presentation. Designated as cephalic or vertex. |
| what is True labor? | Contractions: Regular. Closer together. Stronger. Last longer. The cervix softens, effaces and dilates. |
| what is False labor? | Rarely follow a pattern. Vary in length and intensity. Contractions frequently stop with ambulation and position changes and eventually stop with relaxation interventions The cervix does not change. |
| Nursing Care r/t False Labor: | Focused Assessment: Fetal heart tones. Maternal vital signs. Presence and frequency of contractions. Observation. Discharge. Review guidelines for returning. |
| Which kind of labor is characterized by change in cervical dilation and effacement? | True labor |
| : Which kind of labor is characterized by contractions which subside with relaxation and breathing interventions? | False |
| Fetal condition upon admission | The fetal heart rate (FHR), regular rhythm. The normal average FHR is 110-160 beats/min with 6-25 beat fluctuations. |
| Status of Amniotic Membranes: water breaking/admission. | Ruptured Membranes: SROM. AROM. Observe time, amount, color and odor. Confirm ruptured membranes with: Nitrazine paper. Fern test. |
| Maternal Condition: L/D admission | Assess vital signs: BP Assess for hypertension. Goal is BP less than 140/90. Temperature Assess for signs of infection. Temp above 38 C (100.4 F) should be reported. |

| Mechanism of Labor: in the infant | Descent. Engagement. Internal rotation. Extension. External rotation. Expulsion |
| Stages of Labor: 1ST STAGE: | Dilation. Begins with the onset of contractions until full dilation of the cervix (10cm). This is the longest stage for both the nullipara and multipara |
| Early Latent Phase | Contains 3 Phases: Early Latent. Mild/Active. Transitional. |
| Stages of Labor: 1ST STAGE:Early Latent Phase: | 0 - 3 cm. Contractions mild and infrequent. Gradually increased strength & intensity. Woman sociable & excited; cooperative but anxious. Pain is usually mild at this phase Duration 30 to 40 seconds. |
| Stages of Labor: 1ST STAGE:Mild/Active Phase: | 4 - 7 cm. Complete effacement. Contractions moderate to firm every 2-5 mins Duration 40-60 seconds. Contraction intensity & frequency increase. Woman less sociable, turns inward. May ask for pain medication |
| Stages of Labor: 1ST STAGE:Transitional Phase: | 8 - 10 cm. Shortest phase. Contractions firm; q 1.5 to 2 min. & lasting 60 to 90 seconds. Woman may become uncooperative & hostile; feeling of losing control. |
| Process of Childbirth:Second stage: | Full dilation to birth. 53 to 57 minutes or 79 minutes with epidural for nullipara;17-19 minutes with no epidural or 45 with it for multiparas. Contractions firm;less frequent & shorter duration. Urge to push with each contraction. Regains control. |
| Process of Childbirth:Third Stage | Begins with delivery of baby and ends with delivery of the placenta. Average time is 5 to 30 minutes. Uterine contraction controls bleeding. Oxytocin & breastfeeding stimulate contractions. Minimal pain; cramping. |
| Post third stage of delivery( of the placenta) what should be done at every vital sign interval? | Massaging the uterus to firm it up and compress open vessels at the placental site. Assess uterine tone with each set of vital signs. |
| Process of Childbirth: Fourth stage: | : stabilization. 1-4 post birth. Monitor physiologic changes. V/s, uterine tone, vaginal drainage and assessing perineal tissue are important during this time. Assess bladder for fullness. s/s of hemorrhage by assess lochia. Promote comfort/analgesi |

| what are the five sources of labor pain in most labors? | It is normal pain but it expected/ preparation time exists/ it is time limiting, labor pain has a foreseeable end./labor pain is intermittent/ labor ends with birth of baby. |
| Childbirth pain is 2 types of pain: | Visceral and Somatic |
| What is Visceral pain during childbirth? | this pain is slow,deep,poorly localizedpain that is often described as dull or aching. this pain dominated during first stage of labor as uterus contacts and cervix dilates. |
| What is Somatic pain during childbirth. | this pain is quick,sharp pain that can be precisely localized. this pain dominates during the late first stage of labor and during second stage of labor as the descending fetus puts direct pressure on maternal tissue. |
| Pharmacological Pain Management | Includes: Systemic drugs Regional pain management General anesthesia |
| Regional Pain Management include: | Epidural Block Intrathecal Opioids Analgesics Subarachnoid (spinal) Block (SAB) Systemic Drugs |

| Maternal Physiological changes: CV | compression of the aorta and inferior venacava by the uterus can occure when the women lies supine. displacment is often to the Left. |
| Maternal Physiological changes: Respritory | Full uterus reduces respritory capacity.more rapid and deep breaths, may reduce arterial oxygenation during induction of general anesthesia. normal edem is also present and may make it difficult to intubate. |
| Maternal Physiological changes: GI | progestrone slows peristalsis and reduces the tone of the spincter at junction of the stomach and esophogus. more vulnerable to regurgitation/aspiration of gasteric content when anesthesia is given. |
| Maternal Physiological changes:Nervous system | Endorphines and enkephalins are high. this will reduce the need for pain medications. |

| Amniotomy Nursing Considerations:Identifying Complications: | Fetal heart rate (Baseline and after procedure) Record the color, odor, and amount of the amniotic fluid Report the patient’s temperature if it >100.4 F Green fluid means that the fetus passed meconium |
