how to calculate APGAR score for a newborn? what is a "good" APGAR score? when is APGAR testing done?
A = Activity (muscle tone). 0 points is flaccid. 1 point for arms and legs flexed. 2 points for active motion. P = pulse 0 points for absent pulse. 1 point for <100bpm. 2 points for >100bpm. G = grimace (reflex irritability) 0 points for nothing 1 point for grimaces. 2 points for sneezes/coughs/pulls away A = appearance (color) 0 points for pale blue over entire body 1 point for pink body, with blue extermities 2 points for completely pink color R = respirations 0 points for absent respirations 1 point for slow, irregular respirations 2 points for regular respirations/crying Score of 7 or above=good Done at 1 and 5 minutes after birth - Repeated q 5 min if score <7
Describe the care to provide to a newly circumcised newborn for each type (Gomco/Yellen, Mogen, and Plastibell) of circumcision. Describe the education to provide to the parents about home care of their circumcised newborn.
All types of circumcisions: - Assess for bleeding q 15-30 mins x 1 hour, then q 1 hour for 4-5 hrs - Monitor for first void after procedure Gomco/Mogen circumcision: - Apply Vaseline gauze to the penis for the first 24 hours, then apply petrolatum (Vaseline) until healed to prevent the diaper from sticking Plastibell circumcision: Do not use Vaseline or Vaseline gauze as it causes the string to degrade prematurely Describe the education to provide to the parents about home care of their circumcised newborn. - Check for bleeding with each diaper change - Observe for appropriate urination - Keep area clean...Avoid soap and diaper wipes, cleanse with warm water only to remove urine/stool - Apply Vaseline to glans after each diaper change but not if a Plastibell was used - Loosely secure diaper to avoid pressure - Check for infection - Provide comfort - Don't pull on the Plastibell ring—it will fall off after healing occurs (up to day 14)
newborn's ideal temperature range: newborn's RR: newborns need the temperature in the environment around them to be: postures of newborns that helps them retain heat vs. lose heat? is a baby's inability to maintain it's own temperature because it loses too much heat or can't produce enough heat?
Axillary temp: 97.6-99 Fahrenheit 36.5-37.2 Celsius Normal RR: 30-60 Newborns require higher ambient temperature than adults: 89.6-93.2 F is ideal Posture: Flexed promotes heat retention Extended increases heat loss Inability to maintain normal temperature is usually related to excessive heat loss not impaired heat production

Metabolic Adaptation of newborn - what reserve is low? - what is main source of energy 4-6 hours after birth? - changes from ___ type of metabolism to ___ type of metabolism? Genitourinary Adaptation of newborn - how fast is the glomerular filteration rate? how does this affect urine? - voids within ___ time of birth? - how many wet diapers on days 1, 2, 3+? - something to be aware of when changing diapers of little girl newborns? GI Adaptation of newborns - how are the intestinal and pancreatic enzymes functioning? - how the neonate digest proteins or fats more effectively? - how many kcal/kg/day should the neonate have? - what enters the stomach immediately after birth?
Metabolic Adaptation - Carbohydrate reserves low - Glucose main source of energy 4-6 h after birth - Fuel source consumed quickly...Stress of delivery rapidly uses up hepatic glycogen - Changes from carbohydrate metabolism to fat metabolism Genitourinary Adaptation - Glomerular filtration rate low....Limited capacity to concentrate urine, so urine may be cloudy - Bladder holds 6-44 ml - Voids within 48 hours ----In first 2 days of life produce about 15 ml/kg/day = 2 to 6 wet diapers/day ----Day 3 produce 25 ml/kg/day = 5-25 wet diapers/day - Pseudo menstruation- from maternal hormone withdrawal GI Adaptation - Adequate intestinal and pancreatic enzymes ----Proteins require more digestion ----Absorbs and digests fats less efficiently - Experienced at swallowing/sucking - Stomach capacity 50-60 ml (1-2 oz.) capacity ----Requires 105-108 kcal/kg/day ----Air enters stomach immediately after birth - Cardiac sphincter immature - 5-10% shift of intracellular fluid

N.O. will be using Nitrous oxide for her labor. What are three things you will educate her and her support system about or do to keep her safe? - Education: ----She has to self-administer the Nitrous Oxide-No one can do it for her ----Side effects: Vertigo (most common) and Nausea ----Timing of administration-Works quickly (30-60 seconds of beginning inhalation) and clears quickly (30-60 seconds after stopping) ----Dulls perception of pain - Safety: ----Assist with ambulation ----Supervision during hydrotherapy, birth ball use, and squatting S.S. has been in and out of l & D two times during your 8 hr. shift. She is dilated to 1 cm and is exhausted from her 12 hours of contractions. What sedative can you offer her and why? - S.S. is in prodromal labor and a sedative can help with maternal exhaustion - Ambien 10 mg p.o. is preferred choice due to shorter half life than other sedatives (4.5 hrs. vs. 40 hrs. for secobarbital)- discharged home to sleep - Morphine Sulfate may also be used for prodromal labor-kept in the hospital to sleep - Benefits of Sedative use in prodromal labor ----Decreased anxiety ----Allows for rest- often wake up after several hours sleep in active labor OR she was not in labor and the contractions have resolved E.E. is now 4 cm dilated and is requesting something for her pain. She has been vomiting for the last two hours. Other than the pain medication what else might you give her and why? -Anti-emetic ----Zofran 4-8 mg (IV) ----Phenergan 25-50 mg (IV/IM) q 3-4 hrs.-Most common in active labor ----Visteral 25-100 mg (IM only) q 6 hrs.-Used more commonly in prodromal labor ----Benadryl 25-50 mg (PO/IM/IV) q 6 hrs.-- short ½ life and lasts up to 6-8 hrs.-Usually used at home for nausea and rest Benefits of anti-emetics: -Relieves nausea and vomiting -Decreases anxiety -Potentiates narcotics
what is a major, natural way that newborns generate heat production? Cold stress in a newborn leads to....? What would indicate that a newborn is positioned and latched correctly during breastfeeding?
Non-shivering thermogenesis is a major source of heat production. Cold stress in a newborn leads to hypoglycemia, increased O2 consumption, metabolic acidosis, anaerobic metabolism, reopening of the ductus arteriosus, and reversion back to fetal circulation. - when Metabolic acidosis occurs ----pH decreases, PaO2 drops, PaCO2 rises ----Ductus arteriosus reopens ----Pulmonary vasoconstriction occurs ----Blood shunted away from lungs ----Increased pulmonary vascular resistance ----REVERTS BACK TO FETAL CIRCULATION but there is no placenta to supply O2 correct breastfeeding is shown by = The baby sucks rhythmically and swallows frequently - on the other hand, these are signs of incorrect breast feeding: ----The baby is making smacking noises ----The baby's bottom lip is curled in ----The mother is very uncomfortable during the feeding
Pudendal Anesthesia - what area of the body is injected into? - Produces anesthesia to 3 places? - produces pain relief during what time? - Complications: 3 main ones Local Anesthesia - Injection of anesthetic into where? ---Prior to _____ ---main purpose? - Does not affect ______ - not effective for what pain? General Anesthesia - common or uncommon? - what situation is it used for? - Requires _____ - High rate of ____ - Beware of ________? what preventive measure can you take? - Nursing Responsibilities:
Pudendal Anesthesia - Injection of local anesthesia into pudendal nerve --- Produces anesthesia to lower vagina, vulva, and perineum - Only produces pain relief at end of labor... Has no effect on fetus or progress of labor - Complications: Hematoma, perforation of rectum, and trauma to sciatic nerve Local Anesthesia - Injection of anesthetic into soft tissues of perineum ---Prior to episiotomy ---Repair of lacerations - Does not affect fetus or labor progression - Effect is only locally- not effective for pain prior to crowning General Anesthesia - Used rarely - For emergent C-sections with no or ineffective regional anesthesia - Requires intubation - High rate of neonatal depression - Beware of aspiration pneumonia... A laboring woman's stomach is never empty. restricting food and water is NOT evidence based...don't do it. - Nursing Responsibilities: ---IV access ---Assess when mother ate or drank last ---Administer prescribed premedication such as antacid ---Wedge under right hip ---O2 prior to surgery ---Assist with cricoid pressure. Compression of cricoid cartilage against esophagus helps prevents stomach contents from being aspirated. this is in the throat area.

testing Neuromuscular Maturity - resting posture: extension vs. flexion - Square Window - Scarf Sign
Resting Posture - Extension vs. flexion - premature = extension - mature = flexion Square Window - The newborn's hand is flexed toward the forearm and the angle between the hand and wrist is noted - premature: will easily bend all the way. - angle increases with maturity. Scarf Sign - Pull hand across chest towards opposite shoulder until resistance is met - In the preterm infant there may be little or no resistance so the arm looks like a scarf
explain what each is: - Rooting - Palmar grasp - Tonic neck - Step - Babinski - Truncal incurvation (Galant) - Plantar grasp - Moro
Rooting: Touch infant's lip, cheek, or corner of mouth with nipple or finger; turns head toward stimulus and opens mouth ready to take hold and suck. Palmar grasp: Place finger in the palm of the hand; infant's fingers curl around examiner's finger. Tonic neck: Place sleepy infant in a supine position, then turn head quickly to one side; arm and leg on side to which head is turned extend while opposite arm and leg flex. Step: Hold infant vertically, allowing one foot to touch table surface; infant alternates flexion and extension of feet. Babinski: Use finger to stroke sole of foot beginning at heel, upward along lateral aspect of sole, then across ball of foot; all toes hyperextend, with dorsiflexion of big toe Truncal incurvation (Galant): Place infant prone on a flat surface or suspended in the palm of the examiner's hand, run finger down side of back first on one side and then down the other side approximately 4-5 cm lateral to spine; trunk flexes and pelvis swings toward stimulated side. Plantar grasp: Place finger at the base of the toes; infant's toes curl downward Moro: Hold infant in semi sitting position, allow head and trunk to fall backward to angle of at least 30 degrees (with support); symmetric abduction and extension of arms, fingers fan out, thumb and forefinger form a C; arms are then adducted into an embracing motion and return to relaxed flexion and movement.

what time should you first breast feed the baby for the day? what times should you continue breast feeding the baby? what is the LATCH assessment? how often should you do this assessment? what score is expected for infants 12 hours old? what should you do if mother/baby has a low LATCH score?
Timing - First feeding during first period of reactivity - Feed on demand or at least q 1.5-3 hours L = Latch - 0 points for baby too sleepy/reluctant and no latch is achieved. - 1 point for repeated attempts and baby holds nipple in mouth. stimulate to suck. - 2 points: grasp breast, tongue down, lips flanged, rhythmic sucking. A = Audible swallowing - 0 points: nothing. - 1 point: a few swallows with stimulation. - 2 points: ---if over 24 months of age: spontaneous and intermittent swallowing ---if under 24 hours old: spontaneous and frequent feeding T = type of nipple - 0 points: inverted nipples - 1 point: flat nipples: - 2 points: everted nipples (after stimulation). C = comfort (breast/nipple) - 0 points: engorged breasts. cracked/bleeding/large blisters/bruises. severe discomfort - 1 point: "filling" ?. reddened/small blisters/bruises. mild/moderate discomfort. - 2 points: soft and tender breasts H = hold (positioning) - 0 points: staff has to do a full assist for holding infant at breast. - 1 point: minimal assist from staff. (ex: elevate head, pillows for support). staff teaches one side, mother does the other. or staff holds baby and then mother takes over. - 2 points: no assist from staff. mother is able to position and hold infant. The higher the score the more effective the feeding - A score of 6 or higher by 12 hours of age is expected Lower scores- - Assess every feeding until >6 - Assist and provide education - Consult a Lactation Specialist for evaluation, assistance, and intervention

Reflects hypoxia and increased risk of significant fetal acidemia - Compensatory response: Late decelerations with moderate variability is not associated with significant fetal acidemia Prolonged Decelerations - Gradual or abrupt FHR decrease - Length: lasts between 2 and 10 minutes - Prolonged decels not concerning if: Not recurrent, Normal FHR baseline before and after deceleration, Moderate variability - Cause: any mechanism that causes profound change in fetal O2 ---Uteroplacental insufficiency - tachysystole, maternal hypotension, abruption ---Umbilical blood flow interruption - cord compression, cord prolapse ---Vagal stimulation - profound head compression, rapid fetal descent
"VEAL CHOP" - type of deceleration for VEAL - corresponding cause of decel for CHOP
Variable decelerations = Cord compressions Early decelerations = Head compressions Accelerations ("A-Okay"!) = Okay ??? check this Late decelerations = Problems with placental perfusion (uteroplacental insufficiency)
What are 4 alternative measures you might use to help relieve back pain? List 4 causes of her Pain during 1st stage of labor? What are 4 things you can tell a woman about the effects of a narcotic on her and her baby?
What are two alternative measures you might use to help relieve her back pain? - TENS unit - Intradermal saline injections - Hypnosis - Accupressure/accupuncture 4 causes of her Pain during 1st stage of labor? - Cervical effacement and dilatation - Hypoxia of uterine muscle cells - Stretching of lower uterine segment - Pressure on adjacent structures: referred pain especially to low back, thighs, buttocks, groin, iliac crest What are three things you can tell a woman about the effects of a narcotic on her and her baby? - All systemic medications cross the placenta (Crosses by simple diffusion) - It can decrease FHR variability and respiratory effort especially if given close to her birth - Given at the right time in labor it can help her cope by easing the intensity of the pain. - Unrelieved maternal pain and stress can also have adverse effects on the fetus.
What is a common nursing procedure done prior to epidural placement that is not supported by evidence? E.A. received an epidural and she now has relief only on one side of her body. Is this normal and What can you do to help her? E.A. is considering an epidural for her labor pain. She asks 'how long DOES IT TAKE TO MAKE THIS PAIN GO AWAY?"
What is a common nursing procedure done prior to epidural placement that is not supported by evidence? - Preload with 500-1000ml IV fluids Kinsella found no difference in incidence of hypotension with preload of fluid - However most providers will still preload with fluid because it usually is not harmful to the patient E.A. received an epidural and she now has relief only on one side of her body. Is this normal and What can you do to help her? - One sided blockade is one complication that can occur with epidural anesthesia. - Place E.A. on the side that is un-anesthetized which allows for the nerves to be bathed with the anesthetic. E.A. is considering an epidural for her labor pain. She asks 'how long DOES IT TAKE TO MAKE THIS PAIN GO AWAY?" - It may take up to 30 minutes for the patient to begin to feel full relief
Pharmacological Pain Management - do all drugs given to mom for pain affect the baby? - what must be done before giving medications? - when is the perfect timing to give pain meds? Analgesic vs. Anesthetic vs. Sedation vs. Endorphins - explain difference between these - what are each of these used for? what pain level or type of labor? Know what for each medication?
Whatever she gets will affect the baby - All systemic analgesics cross placental barrier by simple diffusion some more readily than others All consent forms signed before medications Timing - Don't give medications too early as they may slow labor - Don't give too late as you will have an unhappy customer - Give when patient is complaining of pain and has demonstrated she is in active labor Analgesic: Affects perception of pain, does not take pain away. - For moderate - severe pain. Anesthetic: Deadens the pain, either by blocking a nerve, or knocking you out. - For moderate - severe pain. - When prolonged effect desired or analgesia is ineffective Sedation: For maternal exhaustion in prodromal labor Endorphins: Endogenous opiates secreted by pituitary in response to pain Know for each medication - Onset, peak, duration & t-1/2 life of medication - Side effects - Anticipate any potential problems
N.D. has a history of polysubstance Drug abuse. She will be delivering her term baby today. Why should narcan not be used for respiratory depression in this newborn? Three hours ago S.A. received spinal Anesthesia and now is complaining of an itchy nose, neck, and chest. What are you going to tell her about this and what is one medication that can be used to treat it? L.A. delivered her baby girl 20 minutes ago. Since she had an un-medicated labor and delivery what type of pain relief can you anticipate will be used to repair her perineal laceration? S.A. is a g6p5005 who presented to l&d at 7 cm dilated. She has been contracting for only 2 hours and She really wants something to take her pain away. Your hospital does not have nitrous oxide so What type of pharmacological method might be the best and why?
Why should narcan not be used for respiratory depression in this newborn? - Can precipitate withdrawal and cause seizures in prenatally addicted newborns - Also should not be used in a newborn born to a mother on methadone maintenance for the same reason itchy nose, neck, and chest after recieving spinal anesthesia: - common side effect - Medications: ---Benadryl 25-50 mg (PO/IV/IM) q 6 hrs. ---Naloxone (Narcan) may be used because it displaces morphine-like drugs from receptor sites on the neurons ---Nubain or Stadol may also be used as they reverse the analgesic effects of other opioids L.A. delivered her baby girl 20 minutes ago. Since she had an un-medicated labor and delivery what type of pain relief can you anticipate will be used to repair her perineal laceration? - Local anesthesia is the answer. ---- usually Lidocaine without epinephrine....Injection of anesthetic into soft tissues of perineum ---- Effect is only locally- not effective for pain prior to crowning ---- Prior to episiotomy ---- Repair of lacerations ---- Does not affect fetus or labor progression S.A. would be given Spinal anesthesia-Optimal pharmacological method due to rapid onset to provide good pain relief of labor and delivery discomfort - Epidural NOT optimal because it takes longer to work and she will probably deliver before she obtains complete relief - Narcotics/synthetics/sedative NOT recommended due to rapid labor and potential for delivery in near future and risk of respiratory depression - Local and pudendal NOT optimal because will not provide relief of labor pain
Non-Stress Test - how long does this take? - reactive NST requirements for pregnancies over 32 weeks - reactive NST requirements for pregnancies over 32 weeks - non-reactive NST requirement - a reason why you may get a non-reactive NST result
With intact ANS and adequate oxygenation the FHR will accelerate in response to movement Most widely accepted method of evaluation of well-being Electronic monitoring is used for 20-40 minutes Interpretation: Reactive NST or Non-reactive NST Reactive NST - In pregnancies > 32 weeks....15bpm+ above baseline lasting 15+ seconds - In pregnancies 28-32 weeks....10bpm+ above baseline lasting 10+ seconds Non-reactive NST - Insufficient accelerations in 40 minutes - Needs follow-up testing Fetuses have sleep cycles - If NST is non-reactive in 20 minutes continue testing for additional 20 minutes - To wake fetus may use sound or vibration to stimulate movement. can use vibroacoustic stimulation- "buzzer". REMEMBER THAT NST TEST IS "REACTIVE OR NONREACTIVE" RESULTS. the contraction stress test is positive, negative, or equivocal results.
You are assisting with the vaginal delivery of a patient who is in the second stage of labor and screaming that she needs something for pain. She has not received any other analgesia or anesthesia prior to this. Which of the following would be an ideal choice for her? - Ambien, Epidural, Nitrous Oxide, Local anesthesia, or Stadol? You have been caring for g.a. all shift. She is having an emergency c-section under general anesthesia. You know that the potential complications of general anesthesia include: A. Fetal depression that is directly proportional to the depth and duration of the anesthesia B. Increased gastric motility that causes increased appetite C. Uterine relaxation that causes increased blood loss D. Itching of the face and neck E. Slower initiation of bonding and breastfeeding F. A, C, & E G. All of the above What are three signs the woman is able to cope with the pain of labor?
answer: Nitrous Oxide...May be used at any time in labor with onset of relief in 30-60 seconds and rapid clearance after discontinuing inhalation reasons the others are NOT the right answers: - Ambien: Minimal analgesic effects; given orally so no effects will be obvious until at least 1 hour and will last 4-6 hours - Epidural: Most likely won't have full effects until after delivery - Local anesthesia: Won't provide relief of contraction pain - Stadol: Potential for respiratory depression in the neonate You have been caring for g.a. all shift. She is having an emergency c-section under general anesthesia. You know that the potential complications of general anesthesia include: F. A, C, & E A. Fetal depression that is directly proportional to the depth and duration of the anesthesia C. Uterine relaxation that causes increased blood loss E. Slower initiation of bonding and breastfeeding What are three signs the woman is able to cope with the pain of labor? - Able to use her breathing and relaxation techniques, Moaning and chanting, Inward focus, Rocking, Swaying, States "I am coping"
what are the health benefits of newborn male circumcision? Does the Academy of American Pediatricians recommend parents to circumcision their male newborns? Describe the types of pharmacological and non-pharmacological measures that can be used to manage the pain related to circumcision both during and after the procedure.
health benefits of newborn male circumcision: • Prevention of UTI in male infants <1 year old • Reduced risk of penile cancer • Reduced risk for heterosexual acquisition of STI's, especially HIV Despite the evidence showing the benefits of newborn circumcision, the AAP does not recommend routine circumcision of male newborns. The decision is left up to the parents to decide what is best for their child by weighing the medical information with their own religious, ethical, and cultural beliefs and practices. Nonpharmacologic: swaddle, nonnutritive sucking, skin-to-skin with parents, distraction (visual, oral, auditory, or tactile), Vaseline ointment, change diaper promptly, avoid pressure on site when holding or positioning. Pharmacologic: Local anesthesia with a penile block, topical preparations (EMLA), oral sucrose, liquid acetaminophen 10-15 mg/kg after the procedure q 4-6 hours as needed (max of 30-45 mg/kg/24 hrs)

Male sterilization aka Vasectomy - follow up instructions - something you should definitely tell the patient
if a woman uses a diaphragm, it needs to be refitted 6 weeks after giving birth. sponge: - Failure rates: much higher rate for women who have given birth, approximately 25% failure rates with typical use - Safe for breast feeding - Placed in the vagina, covering the cervix - works by blocking sperm and releasing spermicide Progesterone-only pills - "mini-pill" - Failure rates 9% with typical use, (increased effectiveness if breast feeding exclusively for 1st 6 months post partum) - Need to be taken at the same time each day Emergency contraception - "Plan B" - large dose of progesterone - can be taken up to 72 hours after unprotected intercourse to prevent pregnancy. Depo Provera - Progesterone-only intramuscular injection, given every 3 months - Very effective, 6% failure rate with typical use - Can be given immediately postpartum - Safe for breast feeding - May increase risk for depression - May have prolonged return to fertility period (up to 18 months) IUD's - very effective - less than 1% failure rate with typical use - 2 options: Progesterone only - Mirena (5 years) or Copper only Paraguard (10 years) - Both: Immediately reversible, Safe for breast feeding - After placement, very little to "think about or do" - Can be placed immediately postpartum or at 6 weeks - Covered by most insurance companies - Most common side effects: mirena: may skip periods paraguard: increased bleeding/cramping Nexplanon - Progesterone releasing rod, placed by health provider in inner upper arm - Less than 0.5% failure rate with typical use - May be placed immediately postpartum or at 6 weeks - Lasts up to 3 years - Safe for breast feeding - Most common side effect: irregular bleeding Essure - - Trans-cervical approach, spring-like "coils" placed in fallopian tubes, forming scar tissues which blocks tubes - Placed in outpatient setting (no incision needed) procedure at 6-8 weeks postpartum Tubal ligation - - Done in hospital 24-48 hours after delivery (requires abdominal incision) - Very easy to do during c-section Male sterilization: - Vasectomy - Need to go back for semen analysis, will continue to be fertile for up to 3 months after procedure essure, tubal ligation, and vasectomy: - Less than 0.5% failure rate for all methods - All are considered permanent and should not be considered reversible - All are hormone-free, safe to use during breastfeeding
guidelines for maternal-fetal assessment in EFM monitoring - how often would you monitor a low risk pregnancy in the first/second stage? - how often would you monitor a high risk pregnancy in the first/second stage? on the tracing strip for the fetal heart rates, how much time happens between the bolded lines? how much time is each tiny square?
low risk: - first stage monitor every 30 minutes. - second stage monitor every 15 minutes. high risk: - first stage monitor every 15 minutes. - second stage monitor every 5 minutes. May need to assess more frequently Intermittent assessment as appropriate on tracing strip for fetal heart rate, between bolded lines = 1 min. tiny squares = 10 seconds
What is the preferred Narcotic for use in active labor and why? - what preventative action must be taken for woman who are given narcotics during labor? N.N. received a narcotic 20 minutes ago and just had her baby. What effects might you note in the baby from that medication and what would you give to treat it? S.A. had spinal anesthesia during her planned repeat c-section yesterday. She is complaining of a horrible headache today. What procedure might be done to treat this headache?
preferred Narcotic for use in active labor and why? - Fentanyl 50-100 mcg IVP q 15 min. up to 200 mcg max per hr. - Preferred because of rapid onset, short half life and limited placental transfer FHR variability is not affected as much as other narcotics - IV route is preferred because of rapid onset of action - IV medications should be given during the contractions because there is less transfer of the medication to the fetus!!! - Being unsteady when getting up is a common side effect of narcotic medications, and a safety issue. To prevent falls, it is important that patients receiving IV narcotics ask for assistance when they are getting up. N.N. received a narcotic 20 minutes ago and just had her baby. What effects might you note in the baby from that medication and what would you give to treat it? - Neonatal CNS depression- respiratory depression - Narcan (naloxone hydrochloride) 0.1 mg/kg IV, ET, IM - Duration of narcotics often exceeds that of Narcan so may need to repeat it every 3-5 minutes S.A. had spinal anesthesia during her planned repeat c-section yesterday. She is complaining of a horrible headache today. What procedure might be done to treat this headache? - She most likely has a spinal headache - Treatment: A blood patch
AAP Recommendations for breastfeeding timeline and solid food introduction what is the physiology that simulates breast milk to be produced? what hormone causes milk "let down"? - what is the predominant protein in human breast milk vs. cow milk? - what are the vitamins in human milk? - what is another main source of energy in human milk? - what components of human breast milk make up the majority of the calories?
recommend: - Exclusive breastfeeding for first six months - Introduction of solids and other fluids at six months - Continued breastfeeding until at least 12 months After delivery sudden drop in estrogen and progesterone stimulate secretion of prolactin from anterior pituitary and breast milk is produced - Oxytocin: secreted by posterior pituitary and responsible for milk ejection, "Let down" Human Breast Milk: - Whey predominant protein in human milk = 60:40 whey/casein ratio...Easily digested for more frequent feedings - Vitamins ---Fat soluble: A, D, E, K ---Water soluble: Bs, C - Carbohydrates- other main source of energy...40% of calories in diet ---- Primary carbohydrate is lactose ---- Formulas: All lactose, lactose/corn maltodextrin - Fats ----Approximately 50% of calories ----30-50 gm/liter of human milk....Fat content variable - Immunoglobulins: Infection prevention Cow Milk: - Casein predominant in cow milk - 20:80 whey/casein ratio - Less easily digested, forms curds

how do you explain what someone's labor pain will be like? how should you phrase the question when asking about labor pain?
No one can adequately explain what labor pain will be like for someone else Because labor pain is different than any other type of pain the woman doesn't know how she is going to respond to it until she is in actually in labor. Allow the woman to change her mind about what she needs to have the type of experience she desires Many responses to pain - Different cultures will react differently May be better to use the question "How are you coping with your labor?" rather than "Rate your Pain"

The leading causes of Perinatal morbidity and mortality are: - Infection - Hemorrhage - HTN - Emboli Early or Primary Hemorrhage - First 24 hours after birth Late or Secondary Hemorrhage - timing: after first 24 hours after birth and up to 6 weeks post partum - Can wake up in a bed full of blood! - Possible causes: Atony, retained placental fragments (tissue), infection, unknown - Treatment: IV access, Ultrasound of uterus to see if empty, D & C (remove tissue in uterus), Oxytoxics (Methergine, pitocin, hemabate, cytotec), Antibiotics, Ligation of uterine arteries, Hysterectomy - These women are often very sick due to delay of treatment, often in ICU. Normal blood loss Vaginal- 500mls C-section- 1,000mls Maternal deaths from postpartum hemorrhage...1 in 6 maternal deaths in the U.S. Worldwide, a woman dies from PPH every 4 minutes
4 main causes for a postpartum hemorrhage - what is the #1 cause? - what are the treatments for each cause?
Tone: Too full, too fast, too long, too much Pitocin, meds that stop CTX's - Magnesium sulfate, grand multip, or infection. - Atony #1 cause - treatment: ----Anticipate ----Fundal massage (continue until bleeding is controlled), bimanual compression, 2nd IV-fluid replacement, empty bladder ----Medications- used to contract the uterus - Pitocin 10 units IM or 30 units in 500 ml NS "wide open" - Methergine 0.2mg IM (NO HTN) then 0.2mg PO q6h x4 (maintenance dose once PPH controlled) - Hemabate 250mcg IM q15min x3 (NO asthma) - Cytotec 800-1000 mcg Rectally ----Initiate breastfeeding when mother & baby stable - Oxytocin will be released by pituitary and will cause milk "let down" aka eject the milk. Will also help the uterus stay contracted!!! ----Pain meds - all these meds that cause contractions will cause significant cramping so mother will need pain meds Tissue: Retained placental pieces - treatment: ----2nd IV, Prep patient/family and assist with US, manual removal by putting hand into vagina and sweeping placenta pieces out Yes, that is an ARM in her vagina and uterus. ----PAIN MEDS ----NPO - might need surgery (D&C or Hysterectomy if accreta, percreta, increta) - Could this happen after a termination? Yes. You may see retained tissues or retained products of conception. Trauma: Episiotomy, lacerations, sulcus, cervical, uterine rupture, hematomas, uterine inversion - More common with operative vaginal delivery (forceps, vacuum) ---- treatment for LACERATIONS (Cervix, Vaginal side walls (sulcus tears), Perineum, Peri-clitoral).....Have suture, anesthetic, sterile gloves, good light, sponges ----HEMATOMAS (a hidden accumulation of blood) - 500 ml can accumulate in the "potential space" of the iliorectal fossa - Can occur before any vulvar bruising or discoloration noted by RN - May exhibit S & S of hypovolemia out of proportion to estimated blood loss (EBL) - Pain is disproportional to reported perineal laceration and repair - treatment for hematoma: Keep NPO, OR for evacuation, ligate "bleeder" -----UTERINE INVERSION: - Causes: Grand multiparity (5+ babies) OR Mismanagement of the 3rd stage: the person massages uterus before placenta is out, or yanks on umbilical cord very hard - Treatment: What came out first, goes back in first! - This is an emergency! Thromboembolic disorders: Labs, blood bank - Identify....No clotting on the floor or in the bucket = Problem - Anticipate....Identified prior to labor ---- have specific factors for clotting ordered to give the mother to control this problem. ---- Low platelets? Have platelets on hand if mother is already low on platelets and you can give them to her if needed.

Vernix Acrocyanosis "Caput" Succedaneum eye lid edema Milia stork bite, angel kisses, or Telangiectasia Nevi Epstein pearls Natal Tooth Sucking blister Polydactyly Lanugo Sacral dimple or Pilonidal dimple Over riding sutures Erythema toxicum Cephalohematoma Pseudo menstration Syndactyly Slate grey spots Nevus Flammeus
Vernix - White cheesy substance on skin - Consists of sebum & desquamated epithial cells - Protects and lubricates skin in-utero - Decreases as fetus nears term - normal Acrocyanosis. - normal. - The baby is working on it's circulation to it's core, instead of the hands and feet. With time, everything will become pink. "Caput" Succedaneum - normal - It is a collection of fluid in the scalp that crosses the suture lines Eye Lid Edema - normal - Can be from pressure from the birth. Can be aggravated by the erythromycin med we give. Goes away pretty quickly. Milia - normal - its hormonal, it is build up of sebaceous glands - Don't pick at it, don't pop them. - will clear up on own by 1 month. stork bite, angel kisses, or Telangiectasia Nevi - It has no clinical significance, it will fade usually by the second year. - More common in light skin babies - it will blanch so you know its not a bruise. Epstein pearls - As the palate of their mouth is fusing together, it overlapped? - It is normal and will go away. Natal Tooth - normal - It is a whole extra tooth. It is usually not rooted into the mouth. - Usually the hospital will pull it so it won't be an aspiration risk (choking hazard). Sucking blister - Babies will suck on anything that comes in front of their face - normal and will heal on its own - Don't pop the blister. Let it heal on its own. Polydactyly - extra fingers or toes - It will fall off on its own, it can also be tied to fall off. It can be tied to family history. - If it is the only abnormality, it is usually okay. If there is extra fingers, toes, etc. it could be part of a syndrome. - If there is no bone, it can be tied off. Lanugo - It is baby hair that keeps them warm and protect their skin in the uterus. - Premature babies will have more than term babies - will disappear as baby matures. Sacral dimple or Pilonidal dimple - May be associated with spina bifida -May need ultrasound to determine if there is a connection to spinal column -If able to see the base of the dimple there is low risk of spina bifida Over riding sutures - The bones moved during birth. The baby needed to fit out of the birth canal. - normal. It will diminish during the first few days. Erythema toxicum - normal and will go away on its own. - AKA "Newborn rash" or acne -No known cause and no treatment -Peak around 24-48 hrs. -Eruption of lesions surrounding the hair follicle -Moves around body and disappear spontaneously - Avoid lotions. Cephalohematoma - NOT normal, this is concerning. - This does NOT cross suture lines. - Baby is at risk for jaundice and hyperbilirubinemia. Pseudo menstration - Very normal in a 3-4 day old little girl - It is withdrawal of the estrogen after the girl has been birthed out of the mom. Syndactyly - Webbing of fingers or toes - can be normal, or it could also be part of a syndrome if there are multiple things wrong. - It can affect walking, doctor can cut to separate tissue. Can also be on the hands. Family history plays a part. Slate grey spots - They are normal/congenital. Normally fade away - Macular areas of blue/black pigmentation usually found on sacrum/buttocks - Dark skinned babies are more likely to have this - Can be mistaken for bruises. Needs to be documented and tell pediatrician. Tell day care providers. Nevus Flammeus - It is a birthmark. It can happen anywhere. Can be called "port wine stain" or "strawberry birthmark". - Non elevated, does not blanch and does NOT fade. - If the baby is also having seizures, it can be part of a syndrome. It is not concerning otherwise. - Sturge-Weber syndrome is suspected if port wine stain is present on the face and the newborn has convulsions—involvement of the 5th cranial nerve

during breast feeding, do you bring the breast to the baby or the baby to the breast? what can help to cause flat or inverted nipples to protrude? when do you start using this method? what can be beneficial for extremely damaged nipples or flat nipples? what negative outcome can come of this?
bring the BABY to the breast. breast shells can help evert nipples. can begin use in late 3rd trimester. Breast Shields - These may be used to assist with latching but it is important to work with lactation before and during use of the breast shields. - With continued use the milk supply can be reduced by 50% or more. - These can be beneficial for extremely damaged nipples or flat nipples.
Results of Decreased Placental Perfusion
decrease in PaO2 --> hypoxemia --> blood is shunted to vital organs --> tissue hypoxemia --> lactic acid --> Anaerobic metabolism in tissues --> metabolic acidosis --> decrease tissue pH --> injury or DEATH

definition: Blood sugar level <40 mg/dl Risk Factors: Neonate of diabetic mother, SGA/LGA, Preterm/Post-term, Hypothermia, Infection, Birth trauma, RDS, Resuscitation Signs and symptoms: Jitteriness, Poor tone, Lethargy, Temperature instability, Apnea, Irritability Nursing Care: Monitor for s/s and identify risk factors, Assess, Prevention, Provide calories
why do late decelerations happen? are early decelerations safe? are late decelerations safe?
how late decelerations occur.... - Decrease in 02 sensed by chemoreceptors --> Vasomotor center - Peripheral vasoconstriction (gut, kidneys, limbs) - Central redistribution (brain, heart, adrenals) --> - increase BP - Baroreceptor stimulation....Parasympathetic response - Deceleration early decels are okay, late decels are NOT okay
Potential causes of late decelerations include: The goal of maternal position changes for a prolonged deceleration is:
hypotension is a cause of late decels Maximizing uterine blood flow
how to assess lochia? - what is too much/too big for lochia? how to tell if it's lochia or not lochia? - color? flow rate? uterus status?
lochia consists of sloughed off necrotic tissue and blood - Assessment includes: Color, Amount, Clots, Gushing, Odor - Stages: Rubra, Serosa, Alba - Too much/Too big: > 1 pad saturated per hour Clots how to differentiate... Lochia - Slow flow from vaginal opening - More with uterine contraction, fundal massage, or breastfeeding - Pooled lochia will be darker in color and coagulated Non-lochial - Contracted/firm uterus - Constant flow - Especially heavy, bright red - What might cause this?
how is a non-stress test categorized? is electronic fetal monitoring better than intermittent auscultation?
non-stress tests are either: reactive or non-reactive Multiple controlled randomized trails have FAILED to prove that EFM is better than intermittent auscultation
relationship between contractions and blood flow to the uterus?
the greater intensity the contraction, the less blood flow to the uterus
