OB Exam 2 Flashcards
Appropriate timing for specific prenatal testing
First trimester ultrasound
confirms pregnancy and viability, determines gestational age, rules out ectopic pregnancy, detect multiple gestations, visualization if doing chorionic villi sampling, detect maternal abnormalities such at cysts, fibroids, etc.
Appropriate timing for specific prenatal testing
Second trimester ultrasound
establish or confirm dates, detect polyhydramnios and oligohydramnios, detect congenital anomalies, assess placenta function, visualization during amniocentesis
Appropriate timing for specific prenatal testing
Third trimester ultrasound
Detect macrosomia, detect congenital anomalies, detect IUGR, determine fetal position, detect placenta previa or abruption, visualization during amniocentesis or external version, amniotic fluid volume assessment, doppler flow studies
Nuchal translucency
between 10-14 weeks via ultrasound to check for abnormality that could indicate chromosomal disorder. Greater than 3 mm is considered abnormal
Fetal heart activity
by about 6 weeks of gestation via transvaginal ultrasound
Placental position and appearance-
18-23 weeks of gestation. Most cases of placenta previa diagnosed during second trimester resolve by term
Amniocentesis
possible after 14 weeks of pregnancy
Chorionic villi sampling
first trimester- popular technique for genetic studies – between 10-13 weeks
Percutaneous umbilical cord sampling
second and third trimesters- used for fetal blood sampling and transfusion
Coombs test
screening tool for rh compatibility.
Biophysical profile scoring-
Fetal breathing movements:
- score 2- at least one episode of breathing movements of at least 20 seconds
- score 0- absent fetal breathing movements or less than 30 seconds
Fetal movements:
- score 2- at least three trunk/ limb movements in 30 minutes
- score 0- fewer than 3 episodes of movements in 30 minutes
fetal tone:
- score 2- at least one episode of active extension with return to flexion of fetal limb or trunk
- score 0- absence of movement or slow flexion and extension
Biophysical profile scoring-
amniotic fluid index:
- score 2- deepest vertical pocket greater than 2 cm
- score 0- deepest vertical pocket less than 2 cm
nonstress test:
- score 2- reactive
- score 0- nonreactive
MSAFP/triple marker
analysis of results- performed at 16-18 weeks of gestation, measures the level of three maternal serum makers; MSAFP, hCG and unconjugated estriol.
**MSAFP alone can detect neural tube defects. Clients who have abnormal findings should be referred to further screening.
a. ) If a fetus has trisomy 21; the MSAFP and unconjugated levels are low and the hCG will be elevated.
b. ) Low values in all markers is associated with trisomy 18 in the fetus
Amniocentesis:
teaching/lung maturity- the aspiration of amniotic fluid for analysis by insertion of a needle transabdominally into a client’s uterus and amniotic sav under direct ultrasound guidance. **Performed after 14 weeks of gestation.
Amniocentesis Teaching:
> explain procedure to patient and obtain informed consent, assist client to supine position and place a wedge under her right hip to display the uterus off the vena cava
> place a drape over the client exposing only her abdomen
> prepare for ultrasound to locate placenta
> cleanse client’s abdomen with an antiseptic solution prior to administration of a local anesthetic
> tell the patient that she will feel slight pressure as the needle is inserted. She should continue breathing because holding her breath will lower her diaphragm
Amniocentesis Teaching 2:
monitor vital signs , FHR and uterine contractions throughout and 30 minutes following the procedure. Client should rest for 30 minutes. Tell client to report any fever, chills, leakage of fluid, or bleeding, decreased fetal movement, vaginal bleeding or contractions. Encourage client to drink plenty of liquids and rest for 24 hours post procedure
Lung maturity
Amniotic fluid is tested to determine whether the fetal lungs are mature enough to adapt to extrauterine life. L/S ratio- 2:1 indicates lung maturity. Absence of PG is associated with respiratory distress.
Diab during preg.
ideal blood sugar during pregnancy should range between 70-110
increased risks to fetus-
> spontaneous abortion related to poor glycemic control
> infections related to increased glucose in urine
> decreased resistance because of altered carb metabolism
> hydramnios which can cause overdistention of the uterus
> premature ROM- preterm labor or hemorrhage
> ketoacidosis- untreated hyperglycemia
> hypo/hyperglycemia
Hypoglycemia
nervous, headache, weakness, irritability, hunger, blurred vision, tingling of mouth or extremities.
Hyperglycemia
polydipsia, polyphagia, polyuria, nausea, abdominal pain, flushed dry skin, fruity breath
Lab tests
routine UA with glycosuria
Glucola screening/1 hour glucose test
- 50 g oral glucose load followed by blood sugar check 1 hour later. Performed between 24-28 weeks gestation. Positive if BS above 130/140- 3 hour testing is done then
Diab interventions
**Women who have gestation diabetes are generally treated with diet and exercise alone. If glucose levels are persistently high, then insulin is begun. Glyburide and metformin may be given for oral hypoglycemics. **
Cardiac Decompensation Assessment
- Increased fatigue or difficulty breathing with usual activities
- Feeling of being smothered
- Frequent cough
- Palpitations

Hypertension related disorders teaching
> Take blood pressure as directed, always sit to take it and use your right arm each time for consistent readings
> Report any increase to health care provider
> Dipstick test you clean catch urine to test for protein
> Encourage lateral position
> Perform NST and daily kick counts
> Instruct the client to monitor I&O.
HELLP syndrome
a variant of gestational hypertension in which hematologic conditions coexist with severe preeclampsia involving hepatic dysfunction. HELLP syndrome is diagnosed by lab tests, not clinically. Symptoms tend to worsen at night and improve in the day time. General feeling of malaise, influenza like symptoms.
HELLP syndrome acrym
- H: hemolysis; resulting in anemia and jaundice
- EL; elevated liver enzymes- elevated ALT or AST, epigastric pain and n/v
- LP; low platelet- less than 100,000 mm. Resulting in thrombocytopenia, abnormal bleeding and clotting time. Bleeding gums, petechiae, and possibly disseminated intravascular coagulation
** important to remember than many women with HELLP syndrome may not have signs or symptoms of preeclampsia with severe features. Most women will have hypertension but proteinuria may be absent, as a result women are misdiagnosed.
Discharge instructions for HELP syndrom
> Maintain bed rest and encourage side lying position
> Promote diversional activities (watch TV, visit with family)
> Avoid foods high in NA and avoid alcohol, caffeine and tobacco
> Drink six to eight 8 oz glasses of water per day

> Administer antihypertensives as prescribed
Eclampsia
severe preeclampsia manifestations with the onset of seizure activity or coma.
- Preceded by a headache, severe epigastric pain, hyperreflexia, and hemoconcentrations (warning signs for convulsions)
Anti-convulsant medication: Magnesium sulfate:
medication of choice for prophylaxis or treatment to depress the CNS and prevent seizures in the client who has eclampsia and severe preeclampsia
Use an infusion control device to maintain regular flow rate
- Inform client that she can initially feel flushed, hot, sedated
- Monitor BP, pulse, respiratory rate, deep tendon reflexes, LOC, urinary output, presence of headache, visual disturbances, epigastric pain, uterine contractions and FHR
- Place client on fluid restriction of 100/125 ml per hour

Abruptio placent
the premature separation of the placenta from the uterus occurring after 20 weeks of gestation
Abruptio placent S&S
- Sudden onset of intense localized uterine pain with dark red bleeding
- Area of uterine tenderness can be localized or diffuse over uterus
- Contractions with hypertonicity

First stage labor
Latent phase 0-3 cm, active phase 4- 7 cm and transition 8-10 cm. (longest stage and can vary the most in length)
*some dilation and effacement, talkative and eager during latent phase, active phase has some fetal descent, feelings of helplessness and anxiety increases as contractions get stronger. Transition patient becomes tired, restless and irritable, can have n/v, urge to push.
Nursing responsibilities-
- perform leopold maneuvers
- perform vaginal exam
- check for ROM (if membranes rupture FHR is most important assessment)
- perform bladder palpitation on a regular basis to prevent bladder distention
- encourage client to void frequently
- assess temp every 4 hours or every 1-2 if ROM.
- Encourage upright positions but frequent body changes.
2nd stage labor -starting after full dilation and ends with the birth
*pushing results in birth of fetus
*pushing results in birth of fetus
Nursing Responsibilities-
- Vitals every 5- 20 minutes
- Assist in partner involvement with pushing
- Promote rest between contractions
- Provide comfort measures such as cold compresses
- Cleanse perineum as needed if fecal material is expelled
- Prepare for care of neonate (check oxygen, preheat warmer, lay out newborn stethoscope and bulb syringe, have CPR equipment ready, check suction)
3rd stage labor - following delivery of the neonate to delivery of the placenta
*placental separation and expulsion
*placental separation and expulsion
Nursing Responsibilities-
- instruct client to push once findings of placental separation are present
- administer oxytocic for expulsion of the placenta to occur
- administer analgesics
- gently cleanse the perineal area with warm water and apply an ice pack
- promote baby friend activities between the family and newborn (skin to skin)
4th stage labor - after delivery of the placenta to maternal stabilization of vital signs – at least first 2 hours after birth
*lochia scant to moderate rubia, achievement of vital signs homeostasis
Nursing Responsibilities-
- Assess B/P and pulse every 15 min for first 2 hours and temperature every 4 hours for the first 8 hours
- Assess fundus and lochia every 15 minutes for the first hour
- Massage the fundus or administer oxytocics to maintain uterine tone
- Encourage voiding to prevent bladder distention
- Promote an opportunity for parental newborn bonding
mother positioning
Positioning- Important to change positions frequently to relieve fatigue, increase comfort and improve circulation.
Nursing Responsibilities- Avoid vaginal examinations if bleeding is present, cervical dilation is the single most important indicator of the progress of labor
Significance of fetal presentation, posterior positioning
Presentation- the part of the fetus that enters the pelvis first and leads through the birth canal- cephalic presentation is most common. Complete breech babies need a c section. Posterior positioning can cause severe pain in the women’s sacrum. Mother may need an episiotomy
Risk for use of opioids during labor
- Crosses the placental barrier, can cause respiratory depression in newborns if too close to birth of baby
- Reduces gastric emptying; increases the risk for nausea and emesis
- Increases risk for aspiration of food or fluids
- Bladder and bowel elimination can be inhibited
- Sedation
- Altered mental status
- Tachycardia and hypotension
- Allergic reaction
Risk for use of general anesthesia
- Respiratory depression- maintain an open airway and cardiopulmonary function
- Administer metoclopramide to increase gastric emptying as prescribed- chance of aspiration of stomach contents
- Risk for clots
- Decrease stomach acid by giving ranitidine
- Chance of hemorrhage- assess client for decreased uterine tone
Risks, interventions, contraindications for regional analgesia/anesthesia
Adverse effects- maternal hypotension, fetal bradycardia, inability to feel the urge to void and loss of bearing down reflex. Headache after a spinal
regional analgesia/anesthesia Interventions
- Administer a bolus of IV fluids to help offset maternal hypotension (have ephedrine available)
- Do not allow client to ambulate unassisted
- Help position and steady the client into a sitting or side lying position with her back curved
- Coach client in pushing efforts
- Monitor vitals
- Have oxygen and suction available
- Monitor for the return of sensation and motor control in the client’s legs after delivery but prior to standing.

Accelerations
visibly apparent, abrupt increase in FHR above the baseline rate. May occur in association with fetal movement or spontaneously. Compression of umbilical vein can be a cause but usually are okay. No interventions required.
Decelerations
- Early decels- gradual decrease in FHR, considered a normal and benign finding. No representation of fetal oxygenation. They are responses to changes in intracranial pressure and cerebral blood flow caused by fetal head compression. No interventions necessary.
- Late decels- FHR decrease begins after the contraction has started and the lowest point of the deceleration occurs after the peak of the contraction. Cause is a disruption of oxygen transfer from environment to fetus; maternal hypotension, epidural, placental previa or abruptio, hypertensive disorders, postterm gestation, DM, intraamniotic infection.
Late decel interv.
- discontinue oxytocin
- assist women to side lying position
- administer oxygen at 10 L by nonrebreathing mask
- correct maternal hypotension by elevating legs
- increase rate of maintenance IV solution
- palpate uterus
- notify physician
- consider internal monitoring, assist with birth if cannot be corrected
variable decels
caused bay umbilical cord compression; short cord, knot in cord, prolapsed cord, cord around fetus or neck
- same interventions plus….
- Assist with vagina or speculum exam to assess for cord prolapse
- Assist with amnioinfusion if ordered
- Assist with birth
True labor
- contractions occur regularly, become stronger, last longer and occur closer together
- become more intense with walking
- are usually felt in the lower back
- continue despite use of comfort measures
- cervix changes
- fetus becomes engaged
False labor
- occurs irregularly or only regularly temporarily
- often stops with position changes
- can be felt in the back or above umbilicus
- can often be stopped through use of comfort measures
- no significant change in cervix
- baby is not present in pelvis
Leopolds maneuver
consists of performing external palpations of the maternal uterus through the abdominal wall to determine number of fetuses, presenting part and fetal lie, degree of descent, location of the fetus’s back
- perform hand hygiene
- ask women to empty bladder
- position women supine with one pillow under her head and her knees slightly flexed
- have a pillow under one of her hips to displace uterus off of major blood vessels
- using palmar surface of one hand, locate and palpate
- auscultate FHR post maneuvers
Coaching with pushing
to ensure the slow birth of the fetal head, the woman is encouraged to control the urge to bear down by coaching her to take panting breaths or exhale slowly through pursed lips as the baby’s head crowns. At this point the woman needs simple, clear directions from one person. Nurse may have to rouse the woman to get her to cooperate in the bearing down process.
Cervical ripening agents: mechanical/chemical:
- administration of a low dose infusion of oxytocin is used for cervical priming
- a balloon catheter is inserted into the intracervical canal to dilate the cervix
- membrane stripping and an amniotomy may be performed
- chemical agents: misoprostol or dinoprostone
Csection: priority nursing action in emergency; risks and complications:
- continue to monitor FHR, VS and urinary output
- help support the client because the psychosocial outcomes of unplanned or emergency cesarean birth are usually more pronounced and negative
- complications: aspiratory, amniotic fluid PE, wound infection, DVT, hemorrhage
prolapsed cord: priority nursing interventions:
- call for assistance immediately
- notify the provider
- use a sterile gloved hand, insert two fingers into the vagina and apply finger pressure on either side of the cord to the fetal presenting part to elevate it off the cord
- reposition the client in a knee chest, Trendelenburg or a side lying position
- apply a warm, saline soaked towel to the visible cord to prevent drying
- administer oxygen at 8-10 L/min via a face mask
- initiate IV access and administer IV fluid bolus
Recognition of uterine rupture:
o client reports sensation of ripping, tearing or sharp pain
o client reports abdominal pain, uterine tenderness
o nonreassuring FHR with indications of distress
o change in uterine shape and fetal parts palpable
o cessation of contractions and loss of fetal station
o manifestations of hypovolemic shock: tachypnea, hypotension, pallor, cool clammy skin
Recognition of uterine rupture:
o client reports sensation of ripping, tearing or sharp pain
o client reports abdominal pain, uterine tenderness
o nonreassuring FHR with indications of distress
o change in uterine shape and fetal parts palpable
o cessation of contractions and loss of fetal station
o manifestations of hypovolemic shock: tachypnea, hypotension, pallor, cool clammy skin
indications of induction/c section:
- postterm pregnancy (greater than 42 weeks)
- dystocia (prolonged, difficult labor) due to inadequate uterine contractions
- prolonged rupture of membranes
- maternal medical complications
- fetal demise
Amniotomy- role of the nurse:
- ensure that the presenting part of the fetus is engaged prior to an amniotomy to prevent cord prolapse
- monitor FHR prior to and immediately following AROM to assess for cord prolapse as evidenced by variable or late decelerations
- Assess and document characteristics of amniotic fluid
- Document time of rupture, temperature every 2 hours and provide comfort measures
Breastfeeding: teaching:
- Place client skin to skin as soon as possible following birth and initiate breastfeeding within the first 1-2 hours
- Wear a well fitting, supportive bra
- Emphasize important of hand hygiene prior to breastfeeding
- To relieve engorgement: have client completely empty her breasts at each feeding. Allow infant to nurse on demand. Apply compresses or take a warm shower prior to breastfeeding
- Apply a small amount of breast milk to nipples to help sore nipples and let it air dry
Fundus: anticipated placement/ intervention if boggy:
- 1 hour after delivery, the fundus should rise to the level of the umbilicus
- Every 24 hour, the fundus should descend approximately 1-2 cm. It should be between the symphysis pubis and the umbilicus by the sixth postpartum day.
- If fundus is boggy, lightly massage the fundus in a circular motion
Assessments: normal/ requiring follow up:
- Monitoring vital signs, uterine firmness and its location in relation to the umbilicus, amount of vaginal bleeding
- Breasts, uterus fundal height and uterine placement and consistency
- Bowel and GI function
- Bladder function
- Lochia (color, odor, consistency and amount)
- Episiotomy (edema, ecchymosis, approximation)
- Vital signs , pain assessment
- Report: numerous large clots and excessive blood loss, foul odor, persistent lochia rubra, redness or swelling and warmth in the calves, redness and tenderness of the breast or fever
Postpartum Lab values/vital signs:
o Heart rate increased immediately after birth and blood pressure may too for a few days
o Respiratory function rapidly returns to normal after birth
o Low grade fever is common for the first 24 hours after birth
o Hematocrit level drops moderately for 3-4 days then should go back to normal by 8 weeks.
o WBC count may rise during and after labor
Assessment and Intervention for a full bladder:
o Excessive bleeding can occur if the bladder becomes distended
o Overdistended bladder can make the bladder mores susceptible to infection
o Assess client’s ability to void every 2-3 hours
o Assess for distended bladder: fundal height above umbilicus, fundus displaced from the midline, bladder bulges above the symphysis pubis, excessive lochia
o Encourage patient to empty bladder every 2-3 hours
o Measure client’s first few voidings after delivery
o Courage client to increase her oral fluid intake
o Catheterize if necessary for bladder distention if the client is unable to void to completely empty their bladder
Discharge teaching: reasons to call your healthcare provider
i. Passing large clots or large amounts of bleeding or an odor
ii. Redness, swelling or warmth to calf
iii. Fever
iv. Redness or warmth to the breasts
v. Postpartum sadness/depression or blues that are not going away
Engorgement Teaching: breastfeeding/bottle feeding:
- To relieve engorgement: have client completely empty her breasts at each feeding. Allow infant to nurse on demand. Apply compresses or take a warm shower prior to breastfeeding
- Do not express milk if mother is bottle feeding. A breast binder can be used, ice packs, fresh cabbage leaves, and mild analgesics. Avoid nipple stimulation
Reducing post- cesarean complications: abdominal distention, thrombus formation:
o DVT- prevention- maintain sequential compression device until ambulation
o Perform active and passive ROM to promote circulation
o Initiate early ambulation
o Avoid prolonged periods of standing
o Have client elevate legs while sitting and avoid crossing legs
o Maintain fluid intake of 2-3 L
o Discontinue smoking
o DVT treatment-
o Encourage rest and elevate extremity
o Warm moist compresses
o Do not massage affected limb
o Administer anticoagulants
o Give Tylenol for pain
Non pharmacological Pain Interventions:
communicate to her health care providers her preferences for relaxation and pain relief measures. No side effects to the baby
- cognitive strategies- childbirth education, Lamaze and patterned breathing exercises, doulas, hypnosis
- gate control theory to promote relaxation and pain relief – aromatherapy, breathing techniques, imagery, music
- effleurage- light gentle circular stroking of the client’s abdomen with the fingertips
- sacral counterpressure- consistent pressure is applied by the support person using the heel of the hand or first
- application of heat or cold
- frequent position changes
- patterned breathing and progressive relaxation exercises
Interpretation and nursing intervention for prenatal labs: Rh, rubella:
> Rubella- a subcutaneous injection of rubella is recommended in the postpartum period prior to discharge. Women should not become pregnant for 28 days after injection. Breastfeeding mothers can be vaccinated. Do not give if family is immunocompromised.
> RH- given within 72 hours after birth if newborn is rh positive. Give at 28 weeks of pregnancy for rh negative mothers.
