What are the principles that influence choice of drug given during labor? | How it affects the mother and fetus; methods that use drugs for reducing pain during birth |
Describe narcotic analgesics | Opioids; avoid if birth is anticipated with 1 hour, because the medications cross the placenta and may cause respiratory depression for mother and baby |
Describe narcan | Antagonist; used to reverse respiratory depression, usually in the infant but may also be given to the mother |
Describe epidural block | Not used if the woman has abnormal clotting, infection in the area of injection, hypovolemia. Adverse effects: maternal hypotension and urinary retention |
Describe spinal block | Dura is punctured with a thin needle. Anesthesia occurs more quickly and profound than epidural. Adverse effects: maternal hypotension and urinary retention |

How is the rupture of membranes verified? | Nitrazine paper test, ferning pattern under microscope (more up to date test is amniosure) |
What is preterm labor? | Occurs after 20 weeks gestation before 37 weeks, main risk are problems of immaturity with newborn |
What are the nursing interventions for preterm labor? | Position woman on her side for better blood flow assessing vital signs frequently, notify HCP if tachycardia occurs |
What is prolapsed umbilical cord? | Cord slips downward in the pelvis after the membranes rupture; can be compressed between fetal head and woman's pelvis, interrupting blood supply to and from the placenta |
What is the nursing interventions for prolapsed cord? | Displace fetus upward to stop compression against the pelvis, place patient in knee to chest or trendelenburg position; assist with emergency procedures, and help calm the mother |
What is a prolonged pregnancy? | Last longer than 42 weeks gestation; placenta ages making delivery of O2 and nutrients to fetus less efficient, fetus may lose weight, fetal skin may peel |
What are the nursing interventions for prolonged pregnancy? | Observe the fetus during labor to identify signs associated with poor placental flow, such as decelerations. After birth, observe newborn for respiratory distress |
What is a uterine rupture? | Tear in the uterine wall; occurs if the muscle cannot withstand the pressure inside the organ. |
What are the nursing interventions for uterine rupture? | Be aware of who is at risk and monitoring labor is essential. Take measure to alleviate anxiety in woman and partner, watch for hypovolemic shock |
What is placental previa? | Abnormal implantation of placenta in lower uterus, bright red bleeding that is not painful |
What are the nursing interventions for placenta previa? | Monitor FHR and character of contractions. Document and record vaginal blood loss, assess v/s every 15min to watch for shock |
What is abruptio placenta? | Premature separation of placenta, may be partial or total. Bleeding is dark red and painful |
What are the nursing interventions for abruptio placenta? | Prep for cesarean and closely monitor vital signs, s/s of shock, a rapid increase in size of uterus could indicate internal bleeding |
What are the indication for cesarean birth? | Abnormal labor, inability of fetus to pass through mothers pelvis, maternal conditions such as GH, DM, active maternal herpes virus, previous surgery on uterus, fetal compromise, placenta previa/abruptio, and fetal death |
What are the risk of cesarean birth? | Mom: hemorrhage, blood clots, injury to urinary tract, delayed intestinal peristalsis, and infection. Baby: inadvertent preterm birth, respiratory problems, injury |
What are the nursing interventions after cesarean delivery? | Vital signs identify hemorrhage or shock, monitor IV site & rate of solution flow, monitor fundus for firmness, height, midline position, assess uterus after cesarean, assess dressing for drainage, lochia for quantity, color, and presence of clots, U/O |
What are the maternal indications for induction of labor? | GH, ruptured membranes without spontaneous onset of labor, infection with the uterus, medical conditions in the woman that worsens during pregnancy, such as DM, kidney/pulmonary disease |
What are the fetal indication for induction of labor? | Fetal problems such as slowed growth, prolonged pregnancy, or incompatibility between fetal and maternal blood types, placental insufficiency, fetal death |
What is anmiotomy? | Artificial rupture of membranes, done to stimulate or enhance contractions. Commits woman to delivery, stimulates prostaglandin secretion |
What is prostaglandin? | Gel or vaginal insert that is applied before labor induction to soften cervix. CONTRAINDICATED: in women with history of uterine myomectomy surgery or previous cesarean because of risk of uterine rupture |
What is augmentation? | Process of augmenting labor that is progressing slowly because of ineffective uterine contractions |
What are the use, side effects, and nursing measures for Oxytocin? | Initiate/stimulate contractions, uterus is more sensitive to drug when labor has already begun. Won't work if cervix is not ripened, STOP if there are signs of fetal compromise. Complications are H2O intoxication, uterine rupture, hyperactive contractions |
What are indications of an episiotomy? | Better control over where & how much the vaginal opening is enlarged. Opening with clean edge is better than a ragged opening of tear |
What are the nursing interventions for episiotomy? | Cold packs applied to perineum for first 12 hours, after that, warm compresses & sitz bath, oral analgesics are usually sufficient |
What do forceps do? | Provides traction and rotation of fetal head when mother's pushing efforts are insufficient to accomplish safe delivery |
What are nursing interventions for forceps? | Place sterile equipment on table, ice is applied to perineum to prevent bruising and edema after delivery. Exam infants head for lacerations, abrasions, or bruising |
How does vacuum extractor assist in delivery? | Use of suction is applied to fetal head so physician can assist the mother's expulsion efforts |
What are nursing interventions for vacuum extraction? | Place sterile equipment on table, ice is applied to perineum to prevent bruising and edema after delivery. Reassure mother that edema will subside |
What is the nursing care for the mother immediately after birth? | Observe for hemorrhage every 15 mins for first hour, vital signs, skin color, assess fundus, lochia, fullness of bladder, U/O, and pain. Promote comfort (keep warm, apply ice packs to perineum) and encourage breast feeding |
What is the nursing care for the newborn immediately after birth? | Maintain thermoregulation, cardiorespiratory function, observe for urination & passing of meconium (document) identify mom & partner (place ID bracelets on mom, baby, partner) assess for anomalies, and administer meds (erythromycin eye drops & vit. K) |
