Can be from dehydration. Why Moms need to drink 8-10 glasses every 24hrs ▪ Cervix • Effacement- thinning out of uterus, needs to be paper thin to deliver, have to be 100% effaced to deliver • Mucus Plug- can lose at 5 weeks before baby is due. Pinkish/Orangish. Okay as long as bag of water does no break because cord could collapse which is a true emergency, moms are than hospitalized till delivery • Mucorrhea- increase in cervical discharge for 3-4 days during ovulation—normal is egg white • Increased vascularity- normal because part of 1/6th of blood goes to uterus • Increased cervical vascularity also causes both the softening of the cervix (Goodell sign) and bluish discoloration of cervix or vagina (Chadwick sign) • Hegar sign—softening of the isthmus of the uterus, the area between the cervix & the uerus • McDonald sign- is an ease in flexing the body of the uterus against the cervix ▪ Cardiovascular System • Increased cardiac output- 1/6th mother blood supply- placenta, fetus, & uterus, & breasts • Decreased blood pressure- lowest point is 2nd trimester, decrease is only slightly o Mom can have postural hypotension- baby puts pressure on SVC when lying flat pushing for delivery.

(babies is higher than mothers) watch o Order of Assessment Tests ▪ Ultrasound ▪ Nonstress Test (if fail then next test below) ▪ BPP (if fail then next test below) ▪ CST [Contraction Stress Test] o Ultrasound- One of the tests for fetal activity ▪ Abdominal Ultrasound • Allows early diagnosis of complications • High frequency sound waves • Safe and noninvasive • Need a full bladder to do Abd ultrasound- have mom drink 1-2 quarts of water • Left lateral tilt to prevent gestational Hypotension ▪ Transvaginal U/S (ultra sound) • Invasive probe inserted vaginally • Detect ectopic pregnancy, abnormalities • Nurses Role o Tell mom to empty bladder before ultrasound o Fetal Biophysical Profile (BPP) ▪ Any physical characteristics of baby ▪ Scored as good=2; nonreactive or not meeting qualifications=0 ▪ 5 responses of baby to stress either • Fetal HR- is done first, reactive to non stress= 2; nonreactive=0 • Fetal Breathing- 1 or more episodes of breathing lasting 30 secs or more in 30 minutes =2, No movement is 0 • Fetal Movement- more than 3 episodes of movement=2, less than 3 episodes of movement=0 • Fetal Tone- rapid flexion & extension=2, slow flexion & extension=zero •

amniotic fluid which is most important ▪ Do if mom fails Nonstress test o Nonstress Test (NST) ▪ Most widely used Tx for antepartum well being done 3rd trimester of pregnancy ▪ Evaluates fetal well being ▪ Electronic fetal monitoring: 2 belts measure fetal activity and FHR (fetal HR) ▪ Monitors responses of the FHR to fetal movement • FHR increases with fetal movement ▪ Start 30 to 32 weeks ▪ Advantages: easy to interpret & no harm ▪ Disadvantages: Mom has to lie still 20min; tracing ▪ Reactive NST/nonreactive NST • Need two accelerations of FHR with or without fetal movement • 15 bpm for 15 seconds in a 20 minutes interval ▪ Nurse’s Role • Put patient in flat in left lateral position(cushion on right side) and tell them to remain still for 20 minutes as much as possible • Tell mom to push button when she feels baby move ▪ Looks for risk of fetal death o Reactive Non Stress Test ▪ Contraction Stress Test (CST) • Do if mom fails NST, then fails BPP (biophysical profile) • Is Oxytocin (Pitocin) challenge test—makes mom contract • When mom is contracting analyze the FHR • Negative (normal finding)- a pattern of at least 3 contractions in 10 min period and no late decelerations of FHR • Positive (abnormal fining/not good)- persistent and consistent late decelerations with 50% of contractions o Because HR of baby keeps decelerating it means baby will not survive the stress of labor so have to do STAT C-section o Amniocentesis ▪ Determines gene abnormalities ▪ Aspiration of amniotic fluid analysis ▪ Done early pregnancy & 3rd trimester [29 or 30 weeks] (is baby thought to be LBW/stopped growing) ▪ Chance test could lead to infection or lose baby ▪ Evaluation of fetal health ▪ Alpha-fetoprotein (AFP)- protein made by baby’s liver • Can be measured from

bright red vaginal bleeding • Go to Dr. if any vaginal bleeding • Types of placenta previa:-- if first trimester deliver may deliver vag b/c can move o Marginal/Low- lying: placenta attached in lower segment but doesn’t reach the cervical os (The opening of the uterine cervix)—Need C-section o Incomplete/partial: os is only partially covered o Complete/Total: cervical os completely covered o ▪

labor VS False Labor ▪ True Labor Contractions: • Get closer together, last longer, and increase in intensity • Discomfort in back and/or lower abdomen • Do not stop with walking—instead contraction intensifies, strengthens, & consistency of contractions increase • Dilate the cervix ▪ False Labor Contractions: • Do not get closer together or increase in intensity • Discomfort primarily in lower abdomen • May be relieved with walking, resting, or hydration • Does not dilate cervix o Pharmacological Therapies ▪ Induce labor & stop preterm labor • Uterine Stimulants (Oxytocics) o Oxytocin

IM 2 injections 24 hrs apart if lungs surfactant not 2:1 ratio • Vitamin and mineral supplement o Fetal Assessment during Labor ▪ Assessment of contractions • External monitoring—most moms start. See on screen when contraction will occur • Internal monitoring—see strength of contraction. Done by physician. FSE (fetal scalp electrode) in lays next to babies head o Baseline fetal HR o Fetal tachycardia o Fetal bradycardia ▪ Types • Early Deceleration—HR have early decelerations. Not negative is OK • Late Decelerations—contraction come & HR decreases—BAD • Variable decelerations—contraction & have variable HR changes could be complication of baby • If baby’s cord comes out of mom= compressed cord and makes baby hypoxic, Put hand in mom & push baby’s head off of the cord/ push cord back in ▪ Leopold Maneuvers: • Consist of performing external palpations of the maternal uterus through the abdominal wall to determine: o Number of fetuses o Presenting parts, fetal lie, and fetal attitude o Degree of descent of the presenting part into the pelvis o Expected location of the point of maximal impulse (PMI) ▪ Optimal location where fetal heart tones are auscultated the loudest in the mom’s abdomen o Assessment Of Contractions ▪ Leopold Maneuvers- RN’s do always B4 measurements • First maneuver (Upper pole) o Head or buttocks or legs o Determine what fetal part is at the uterine fundus • Second Maneuvers (Sides of maternal Abdomen) o Palpate with one hand on each side of abdomen o Palpate fetus between two hands o Assess which side is spine and which is extremities • Third Maneuvers (Lower pole) o Palpate just above symphysis pubis o Palpate fetal presenting part between two hands o Assess for fetal descent (where baby is in pelvic cavity) • Fourth Maneuver (Presenting part evaluation) o Apply downward pressure on uterine fundus o Hold presenting part between index finger and thumb o Assess for cephalic versus breech (buttocks) presentation • Nursing considerations for Leopold Maneuver: o Have mom empty bladder before o 45 degree angle with knees bend slightly o Have mom in left lateral position (on left side) o Then palpate Mom ▪ o Physical Changes ▪ Pre-labor Warning Signs • Lightening- mom can breathe better cuz baby drops • Contractions o Braxton Hicks • Cervical Changes: Dilation & effacement o Determine by palpating o Paper thin 100% o Need 10cm dilated & 100% effacement before the mom can push o If mom pushes before 10cm & 100% she will get a hematoma & a lot of swelling • Bloody Show: mucus plug • Rupture membranes • Nesting- burst of energy to get baby room ready • Weight loss of 0.5 to 1.4kg (1-3 ibs) • Increased backache and pressure • G.I. upset o Stages of Labor ▪ First stage—takes the longest • Early Phase—contractions aren’t that bad • Active Phase--want mom to come to hospital if contractions 3-5 minutes apart • Transitional Phase—most discomfort mom will have. Contractions are very intense 1-2 minutes apart 5-7cm dilated ▪ Second Stage • Pushing—some moms push for 1 hr or 45 minutes fast birth called precipitous delivery. Others are normally 2-3 hrs • Delivery of the baby ▪ Third stage • Delivery of the placenta • Do skin and skin with baby & do one last push to get placenta out o The Five P’s ▪ Passage: Birth canal ▪ Passenger: Fetus & placenta ▪ Position: Fetal head ▪ Power: Contractions ▪ Psyche: Confidence ▪ And interaction between the passage (canal) and the passenger is most important o 1) Passage: Birth Canal ▪ Bony Pelvis • 4 bones • Support and protect pelvic contents • Form relatively fixed axis of birth passage ▪ Four Bones: • 2 inominate bones, sacrum, coccyx • Sacroiliac bones have degree of mobility (hips) ▪ False Pelvis: • Portion above the pelvic brim, or linea terminalis • Supports weight of enlarged pregnant uterus • Directs presenting part into true pelvis (base) • ▪ True Pelvis: • Portion that lies below linea terminalis • Made up of the sacrum, coccyx, &innominate bones & represents the bony limits of the birth canal • The relationship of the true pelvis & fetal head is very important o The size and shape of the true pelvis must be adequate for normal fetal passage during labor & birth • Determines passage of the fetal head o Pelvic inlet ▪ Upper border of true pelvis ▪ Typically rounded o Pelvic cavity o Pelvic outlet (baby comes out the outlet) ▪ Lower border of true pelvis ▪ The anteroposterior diameter of the pelvic outlet increases during birth as the presenting part pushes the coccyx posteriorly ▪ The Pubic arch is of great importance b/c fetus must pass under it during birth • If arch is narrow baby’s head may be pushed backward toward the coccyx, making extension of the head difficult • May require the use of forceps or a cesarean birth • The shoulders of a large baby also may become wedged under the pubic arch making birth difficult ▪ Pelvic Types: • Gynecoid- most common & best for vaginal delivery o Wide and round pubic arch • Android—male type pelvis, heart inlet, small inlet o Narrow, sharp, deep pubic arch o Not favorable for a vaginal birth o Descent into pelvis is slow • Anthropoid- baby born face up because of oval shape o Normal or moderately narrow pubic arch • Platypelloid- more oval-ish, flat female pelvis results in baby being born transverse- needs to have C-section o Has extremely wide pubic arch, transverse diameter is wide, but anteroposterior diameter is short o Outlet inadequate for vaginal birth ▪ ▪ Soft Tissue: • Cervix & vagina form birth canal • Effacement 100% • Dilation of cervix 10cm o 2) Passenger Fetus: ▪ Head: Fetal Skull (cranium) ▪ Most important to labor and birth—Head Size ▪ Molding is overlap of bones ▪ Sutures (membranous) ▪ Fontanels o Fetal Lie ▪ Relationship of the cephalocaudal axis of fetus to cephalocaudal axis of mother • Longitudinal/parallel- vertebra lined up with mother • Transverse—baby is in transverse or horizontal position and has to have C-section to be born • Oblique—head at 45 degree angle head going toward inlet, when baby’s head is in the mother’s hip. Baby’s head & body are diagonal not vertical or horizontal (transverse lie) • Baby should be facing down ▪ o Fetal Attitude: ▪ Relationship of fetal parts to one another ▪ Fetal flexion: chin flexed to chest—completely flexed • Smallest head diameter passes through birth canal ▪ Fetal extension: chin extended • More difficult—presenting part chin, called mentum o Station ▪ The relationship of the presenting baby part to the ischial spines ▪ Engagement: head passes through pelvic inlet ▪ For a baby to be delivered has to be +4 or +5 to pelvic inlet ▪ Negative numbers are before Ischial spines & positive numbers are after the Ischial spines ▪ Inlet= -5cm ▪ Floating over false pelvis= -4 ▪ Ischial spines=0 (Engaged baby will not go back after hitting this mark, means baby has entered True pelvis) • Correct Term is the baby is Engaged when charting • Station Zero= when the fetal vertex is at the level of the Ischial spines ▪ +1, +2, +3 mean baby is headed toward the cervix ▪ +3 = Baby beginning to emerge from Birth canal ▪ Outlet= +5 (means he baby is crowning) ▪ o Fetal Presentation ▪ Fetal part entering the pelvis first ▪ Three main ways a fetus can present • Head—cephalic • Feet or buttocks—breech • Shoulder presentation—scapula o Fetal Position ▪ Relationship of the fetal presenting part to the front, side, or back of maternal pelvis ▪ Noted by 3 letters (example ROP,LOP) • Maternal pelvis (which way is baby’s spine is): right (R) or left (L) • Fetal presenting part: Occiput (O), Sacrum (S), Mentum-chin not tucked in (M), Scapula (Sc) • Maternal Pelvic Aspect (baby’s spine to pelvis)- anterior (A) baby is facing down, posterior (P), or transverse (T) • • o 3) Powers ▪ Uterine contractions • Primary power—frequency, duration, intensity • Effacement and dilation • Each contraction has 3 phases: o Frequency—should be hospitalized if 5 minutes, beginning of one contraction to beginning of next contraction o Duration—beginning to end of some contraction o Intensity—ACME how high on the graph contraction goes o 4) Maternal Position (look in book at positions) ▪ Frequent position changes: • Comfort • Relieve fatigue • Promote circulation • Determine by maternal preference • Health care provider • Condition of mother & fetus • Level of anesthesia received • Peanut (birthing bowl)—when mom has an epidural and squats in bed to push out baby into bowl • o 5) Psyche ▪ Factors Affecting Psyche • Mental & physical preparation for childbirth • Sociocultural values & beliefs • Previous childbirth experiences • Support from significant others • Emotional status ▪ Nursing Tip • Provide emotional support to laboring women so she is less anxious and fearful • Excessive anxiety or fear can cause greater pain, inhibit the progress of labor, & reduce blood flow to the placenta o Pain Management ▪ Pain Threshold and Tolerance • Threshold • Tolerance ▪ Source of Pain during Labor • Dilation and stretching of cervix • Reduced uterine blood supply during ctx (ischemia) • Pressure of fetus on pelvic structure • Stretching of vagina and perineum o Non-pharmacological pain management: ▪ Child education: breathing & relaxation ▪ Imagery: use of focal points ▪ Changing positions, emptying bladder, walking o Pharmacologic Pain management: ▪ Analgesics: decrease pain • Butorphanol (Stadol) and Nalpbuphine o Don’t use Demerol anymore b/c respiratory depression • Nalaxone (Narcan) o Used if baby has depressed resp. rate ▪ Anesthetics: decrease sensation • Epidural/spinal anesthethesia: Marcaine and fentanyl • Local: for episiotomy: lidocaine and bupivacaine—if have a tear • General anesthesia—c/s emergency for placenta abruption ▪ Pudental: local anesthetic, pudental nerve if no epidural so not as much pain o Procedure for Anesthetics ▪ Epidural anesthesia • Bolus of IV before procedure • Monitor BP • Sit on side of bed • Injected into epidural space • Takes 20-30 minutes • Biggest problem is hypotension • Waste down is numb • Give 100mL IV fluid to prevent hypotension • Test dose Lidocaine ▪ Spinal Anesthesia • Sit on side of bed • Administer directly into the spinal sac • Works immediately • Does not do hypotension • Chest down is numb Fluid & Electrolytes (6 question on Exam) • Fluid Volume Deficit o Common o Decrease in intravascular, interstitial &/or intracellular fluid in the body o Alone or in combination with electrolyte or acid base imbalances o Dehydration—loss of fluid alone o Happens faster in pregnant women & moms recover slower • How infants & Younger children Differ from Older Children & Adults o Infants more vulnerable to alterations in fluid & electrolyte balance ▪ Because infants have highest proportion of water, accounting for 70%- 80% of their body weight (water% decreases with age) o Greater fluid intake & output related to size o Happens fast o Slower adjustments o Amount of body fat (muscle holds fluids better) • Why do Infants differ from Adults & older children o Lose greater proportion of fluids each day o Children may not feel thirsty and so fail to drink even when dehydrated o Kidneys are immature and inefficient ▪ Infants lose more fluid through the kidneys because immature kidneys are less able to conserve water than adult kidneys ▪ Kidneys are immature until 2 years old o Little reserve o Infants have high daily fluid requirement o Extracellular fluid (ECF) compartment is larger & constitutes greater proportion of body weight—greater insensible loss o Greater body surface area ▪ Gain more heat in hot weather and lose more in cold weather o Higher basal metabolic rate (BMR) because growing ▪ Also increase when they have a fever o Preemies have most body water, than an infant, than an adolescent o Lose a lot of water during birth o Water goes through GI faster • Implications of feeding o Newborn can be overhydrated if formula diluted too much or undehydrated if concentration of formula is not right • Dehydration o Common fluid imbalances: ▪ Total output total intake ▪ Infants more susceptible to infection—rotavirus (rotavirus causes gastroenteritis) ▪ Insensible losses • Heat lamp=more water lost (phototherapy used to Tx hyperbilirubinemia) • Wounds or burns • GI losses • Types of Dehydration o Isotonic dehydration —primary form in children electrolyte and water deficits equal o Hypotonic dehydration—electrolyte deficits (Na) greater than water deficits (diarrhea & vomiting, burns & renal disease) ▪ Fluid shifts from extracellular (outside cell) to intracellular (inside the cell) in attempt to establish normal proportions ▪ Cells swell rapidly as water rushes in them o Hypertonic dehydration—water loss greater than electrolyte loss, electrolytes are above normal levels [mostly Na] (NG feedings, intravenous fluids, or diabetes insipidus) ▪ Intracellular (inside cell) shifts to extracellular (outside the cell) ▪ Cells lose water & shrink o • Elevated Electrolyte Level o Hypernatremia (increased Na) and Hyperkalemia (increased K) are the most common and significant extracellular findings o Manifestations ▪ Hyperkalemia • Fatigue • Nausea • Muscle weakness • Cardiac irregularities • Tx- administer glucose and insulin to lower K by driving K into intracellular space. Diuretics will increase K & Na loss but also remove fluid ▪ Hypernatremia • Swelling • Irritability • Muscle spasms • Thirst • Confusion • Coma ▪ Hypercalcemia • Nausea & vomiting • Excessive thirst • Frequent urination • Constipation • Muscle pain • Low Electrolyte Level o Hypokalemia (Low K) is most common result of diuretics unless K sparing o Manifestations ▪ Hypokalemia • Cardiac arrhythmias • Nursing assessment o General appearance o Weight measurements o Level of consciousness (crying? Sleeping? Unresponsive?) o Vital signs ▪ Change in v/s may indicate or in some cases precede fluid, electrolyte and acid-base imbalance balance ▪ Elevated temp may be result of dehydration or a cause of increased body fluid losses ▪ Tachycardia is an early sign of hypovolemia ▪ Pulse volume will decrease if a fluid volume deficit is present and increase in the case of fluid volume excess ▪ BP decrease for fluid volume deficit and hypovolemia or increase with FVE ▪ Orthostatic hypotension may also occur with FVD and hypovolemia o Intake & output o Skin turgor, mucous membranes o Fontanel—sunken in? o Extremities (capillary refill) • Severity of clinical Dehydration (Deff Know for Exam) o Mild 5% o Moderate 6-9% o Severe 10% o Chart in book • Dehydration Severity o Mild (hard to detect) ▪ Infants irritable & older children thirsty ▪ Blood pressure, pulse, & resp. are normal ▪ Mucous membranes moist ▪ Urine normal ▪ Capillary refill and tears normal o Moderate ▪ Restlessness and irritability (infants) ▪ Alert, thirsty, & restless (older children & adolescents) ▪ Skin turgor poor ▪ Urine dark and decreased output ▪ Pulse rate & RR normal but BP is normal or low ▪ Mucous membranes dry ▪ Thirst increased ▪ Fontanelle sunken in ▪ Capillary refill increases & tears decreased o Severe ▪ Lethargic to comatose (infants & young children) ▪ Decreased consciousness or apprehensive (older children & adolescents) ▪ Blood pressure low to undetectable ▪ Pulse tachycardia or bradycardia ▪ Respirations changing rate & pattern ▪ Skin turgor very poor ▪ Mucous membranes parched ▪ Urinary output decreased or absent ▪ Thirst greatly increased ▪ Fontanelle sunken in ▪ Capillary refill (greater than 3-4 seconds ) o Weight ▪ Each Kg of weight is equal to 1 L of fluid ▪ Rapid weight loss is a good indicator of fluid volume deficit ▪ Subtract the child’s current weight from the original weight ▪ Divide loss by original weight=% of dehydration ▪ 1 L of fluid= Approx 1KG ▪ Example 14kg original weight ▪ 14 kg original weight of infant ▪ Now weighs 13.6kg 14-13.6kg=0.4kg ▪ 0.4/ 14=0.0028 rounded to 0.03 ▪ Express as percent (x100)=3% which is mild dehydration o Oral Rehydration ▪ Major worldwide health care advances ▪ More effective, safer, less painful, & less costly than IV hydration ▪ Enhance & promote reabsorption of sodium & water ▪ Greatly decreases vomiting, volume loss from diarrhea & duration of illness ▪ Keeps kid out of emergency room ▪ D5 1/2NS--hypertonic ▪ 5-10mL every 5 to 10 minutes o Administer of Parenteral Therapy ▪ Fluid deficit severe ▪ Unable to take fluids ▪ Administer IV fluids ▪ Hypertonic dehydration (rapid fluid replacement contraindicated because of risk of cerebral edema) ▪ Avoid Potassium replacement until renal function verified ▪ H&H, BUN, CR, and electrolyte labs ▪ Lab vales similar to adults o Daily Maintenance Fluid Requirements (ORT therapy equation) (Know equation not given on Exam) ▪ 1) know how much the child weighs ▪ 2) Allow 100ml/kg/day for first 10kg (1000ml/day) ▪ 3) Allow 50ml/kg/day for second 10kg (500m/day) • (+ 1000ml from first category) ▪ 4) allow 20ml/kg/day for remainder of kg above 20 • (+1500ml from first 2 categories) ▪ 5) divide total amount by 24 hrs to obtain rate in milliliters/hour ▪ Example 1: • If child weighs 7.2 kg • 7.2kg * 100ml/kg/day=720ml/day • Then 720ml/day/24hrs= 30ml/hr ▪ Example 2: • If child is 22kg • 1000ml/day+ 50ml/day+20ml/day+20ml/day= • 1540ml/day / 24hrs = 64.17ml/hr ▪ Example 3: • If child is 15kg o 1st 10—100ml/day o 2nd 10—250ml/day (because 5kg*50ml/day=250ml/day) o Add them together= 1250ml/day o 1250 / 24hrs = 52.08ml/hr Perfusion (7-9 questions on exam) • Preeclampsia—hypertension disorder of Pregnancy o Perfusion (heart) then to central then to tissues o With Preeclampsia central and tissue perfusion is impaired or absent o Preeclampsia starts 20 weeks & ends when the baby is born • Definition of Preeclampsia o Pregnancy—specific syndrome o Occurs 20 weeks gestation—ends when baby is born o Hypertension + Proteinuria ▪ NEED both to be diagnosed with Preeclampsia ▪ These symptoms to look for ▪ Varying degrees on a scale • Mild Severe Preeclampsia • Mom can fall anywhere on the scale but can only get more severe cannot go back to mild o Etiology of Preeclampsia ▪ Etiology is unknown ▪ Theory: • Starts with implantation of placenta ▪ Research has demonstrated abnormal placental development or placental damage from diffuse microthrombosis as playing a role in the development of maternal hypertension ▪ An altered maternal immune response to fetal/placental tissue may also contribute to preeclampsia o Pathophysiology ▪ Pregnancyincreased blood volume Release of prostacyclin and endothelium relaxing factors (tells the blood vessels o dilate & accommodate the extra fluid)blood vessels dilate (vasodilation)  Defective placentaIncreased sensitivity to Angiotensin II (vasoconstrictor) blood vessels constrict Increased blood volume + vasoconstriction = Hypertension ▪ There is hyper responsiveness to angiotensin II and epinephrine in moms with preeclampsia ▪ BP are liable (can change quickly) in preeclampsia, normal circadian rhythms may be reversed or blunted (weakened) o Risk Factors for Preeclampsia ▪ Teenagers and women over 35 especially if Primigravida (first baby) ▪ Family Hx—genetic component ▪ Multiple gestations—twins, triplets ▪ Obesity—causes placenta not to implant properly ▪ Medical Hx of hypertension or kidney disease o Mild Preeclampsia (Sick) ▪ Few if any symptoms ▪ Elevated BP (140/90mmHg) ▪ Protein in urine (1+ or 2+ dipstick) • Protein should not come through kidneys, it should be held onto ▪ Slight Edema is present • Puffy face • Puffy hands • Ankles • Periorbital edema ▪ Third spacing • Fluid pushed into third space by edema • Occurs when too much fluid moves from the intravascular space (blood vessels) into the interstitial or "third" space-the nonfunctional area between cells o Severe Preeclampsia (Sicker) ▪ BP greater than or equal to 160/110mmHg • On 2 occasions at least 6 hrs apart while on bedrest ▪ Proteinuria 5g found in 24hrs urine • Dipstick 3+, 4+ on 2 samples at least 4hrs apart ▪ Increased BUN & CR • Acute Kidney failure b/c kidneys getting hit with high BP ▪ Oliguria (UO 500mL/24hrs) • Kidneys start to fail so produce less urine ▪ Deep tendon reflex +3 or +4 ▪ Weight gain ▪ CNS Symptoms (affecting all vessels in the body) • Headache • Blurred Vision • Tinnitus • Hyperreflexia o Has Eclampsia (no more pre) [sickest] ▪ Kidney failure ▪ Emergency C-section ▪ No urine output at all ▪ CNS Symptoms • Seizure (most babies do not survive seizures) • Altered consciousness caused by cerebral edema or cerebral vasospasm ▪ Fetal demise or abruption o Maternal Risks for Severe Preeclampsia ▪ Increased risk for renal failure ▪ Abruptio-placentae • Placenta detaching self from uterine wall • If placenta abrupt’s & detaches baby dies b/c cut off from 02 & nutrients ▪ CNS: seizure (CNS so jacked up mom has a seizure) ▪ Rupture Liver—from the pressure ▪ Pulmonary edema—fluid forced into lungs ▪ May develop hypertension later in life o Fetal/Neonatal Risks (Severe Preeclampsia) ▪ Small for gestational age (SGA) • Baby is scrawny and skinny ▪ Over sedated at birth • From Mg sulfate ▪ Decreased Placental Perfusion • Decrease in 02 (B/C placental defect decrease in 02, vitamins, electrolytes) • Chronic hypoxia • Fetal distress o Nursing care ▪ Bedrest • If mom sent home on bedrest will have to be taught to assess BP, weight, protein in the urine and log fetal movement daily • Mom should report absence of movement ▪ B/P every few hrs—want V/S to go down ▪ Edema daily weights • Increase in ibs=more edema, or water ▪ Deep tendon reflexes (+1,+2,+3,+4) • Checking CNS B/C is jacked up and Mom can have seizure ▪ Fetal monitoring—want baby to survive ▪ Intake & output—kidney function ▪ Dipstick urine for protein—kidneys, how much protein is lost ▪ High protein diet/low sodium diet • High Na foods should be limited to 6g/day ▪ Bedrest: Mom should be on left side/low stimuli • Get uterus off vena cava • No TV, NO cellphone, low lights so she does not have seizure ▪ If edema elevate extremities • Daily labs o BUN & CR ▪ BUN 7 to 20mg/dL ▪ Cr 0.6-1.2 mg/dL o Medical Therapies for Severe Preeclampsia ▪ Anticonvulsants • Magnesium Sulfate (Drug of choice) o Given IV ▪ Fluid and electrolyte management • Clients are hypovolemic due to edema (shift into third spacing) ▪ Pharmacology • Valium—to calm down Mom • Apresoline—If BP is too high o Magnesium Sulfate IV ▪ Acts as CNS depressant by blocking neuromuscular transmission ▪ Also acts as smooth muscle relaxant to help reduce blood pressure ▪ Excreted by kidneys • Monitor mom for toxicity by watching BUN& Cr • Do not want Mg to build up in Moms blood • Can increase fluid intake to flush out Mg but watch for fluid overload ▪ Vesicant—kills tissue & can be necrotic if gets in intestinal tissue • If Mom is in any pain after administration she needs to use call bell immediately ▪ HIGH ALERT DRUG • Need two nurses to verify patient, drug, amount and IV site before administration • We use drug no more than 5-7 days because of toxicity ▪ First Test Dose • Makes patient act drunk • Can have slurred speech or flushed skin ▪ Magnesium Blood Levels • Therapeutic range for Mom: 4-8 (if lower than 4 not helping moms preeclampsia ) • Reflexes (deep tendon) will start to disappear at 9-13 o Stop Mg & get stats Mg blood check o Should have Calcium Gluconate (antidote) at bedside at all times 10mL in 10mL syringe • Respiratory depression at 14 • Death at 30 ▪ Nursing considerations for Mg Sulfate • Signs to watch for if Toxicity o Drowsiness o Decreased RR, Decreased HR, Decreased BP o Flushing of skin, sweating o Diarrhea o Bad headache—(monitor neuro-status) o Muscle weakness o Loss of tendon reflexes • Toxicity in the Baby after birth o Difficulty breathing immediately after birth can be reversed with medication • If notice toxicity what does Nurse do? o Stop IV o Administer Calcium Gluconate IVP (IV push) • Contraindications o Do not use more than 5-7 days for preterm labor (risk of decreased Ca, bone changes in baby) o Avoid continuous use during active labor or within 2hr of delivery (Mg toxicity) • Implications o Have to have two Nurses verify order, drug, patient, & IV site before administering Mg sulfate o Monitor newborn for decreased BP, hypoflexia, decreased RR (Fetal Monitoring) o Monitor I &O, output should be greater than or equal to 100mL/4hrs o Monitor Neuro-status and tendon reflexes before & during Mg therapy ▪ If patella reflex is absent STOP drug o RR should be 16 before Mg is given o Pt should be side lying on left side with dim lights, no TV, No phone—low stimuli o Antidote Calcium gluconate should be at bedside at all times with 10ml syringe and needle to draw med up o Make sure room is set up with emergency breathing equipment-- 02 tubing, nonrebreather mask, ambu • Eclampsia Definition bag, suction equipment (tubing & catheter)-- incase mom does have seizure o Preeclampsia that has progressed to seizures or coma o Characterized by grand mal convulsion or coma ▪ May occur before the onset of labor, during labor, or in early postpartum period o Mom will have immediate C-section if progresses to seizure or coma • Only cure for preeclampsia is birth of the child o Client with preeclampsia usually improves rapidly after giving birth o After birth seizures can still occur up to 48hrs postpartum o Physician may order hydralazine or magnesium sulfate after delivery in severe cases of preeclampsia • Nursing Considerations o BP should be assessed at least every 1-4 hrs, more frequent monitoring is needed with changes in client status o Client should be weighted daily at the same time o Temp, pulse, & resp. should be monitored every 4 hrs o Fetal HR-- is assessed with maternal vital signs ▪ A late deceleration or a decrease or absence in variability indicates fetal distress o Urinary output—I & O should be checked monitored and recorded every shift or more frequently per physician order. ▪ Output should be at least 30mL/hr o Urine Specific gravity—findings over 1.040 correlate with oliguria and proteinuria o Deep tendon reflexes—assess for evidence of hyperreflexia ▪ The patellar reflex is the easiest to assess ▪ Clonus should also be asses by dorsiflexing the foot while the knee is held in a fixed position ▪ Normally no Clonus is present o Level of consciousness—any change is level of consciousness or mental status should be reported o Pt should be on left side (left lateral position) even when giving birth, if Pt can’t push while on left side she should be encouraged to move into a semi sitting position o Non stimulating environment o Oral contraceptives may be used if the woman’s blood pressure has returned to normal by the time they are prescribed (usually 4-6 weeks) Antenatal Lab Notes o Loading dose: infuse 4 grams of Mg Sulfate IV in 250mL of NS to run over 30 minutes and then follow with the maintenance dose. What rate would you set the infusion pump? o 250mL/ 30minutes * 60min/ 1hr = 500mL/hr o Maintenance dose: 40 grams of Mg sulfate in 1 L of D5W to infuse at 2 grams per hour X 24hrs.
