Intro to Maternity Nursing A. Role of the Perinatal Nurse I.

II.

The Registered Nurse a.

Scope of nursing practice determined by: -Calif State Nursing Practice Act-BRN -Community standards -Policy and Procedure of facility -JCAHO-Joint Commission on Accreditation of Healthcare Organizations -Dept. of Health Services

b.

Nurses held legally responsible for practicing within scope of practice

c.

Specialty Organization: AWHONN -Association of Women’s Health, Obstetrics, and Neonatal Nurses

d.

Orientation Period/Specialization -Labor and Delivery -Nursery/Level II Nsy/NICU -Postpartum/Mother-Baby-↑ since 1990’s -Occasional problems with comprehensive care-territorial -Differences in opinions lead to pt confusion

Expanding roles in Perinatal Nurses a.

Nurse Practitioners -Defined by ANA as: provide comprehensive health assessments, determine diagnoses plan/prescribe treatment manage healthcare regimens for the individual, families, and the community -In 1960’s, shortage of MD’s lead to 1

3

2 creation of the RNP -May provide family care or specialize -Take part in a certificate program or Master’s Degree program -Need at certification for third-party reimbursement -Requires documentation of continued education and practice b.

Clinical Nurse Specialists -Defined by ANA: Clinical expert who provides direct pt care services --health assessments --health promotion --preventative interventions -MSN -Expertise in planning, supervising, and delivery of nursing care to families in childbearing period -Case managers -Consultant -Family and staff educator -Coordination of delivery of nursing care to families requiring intensive nursing support -Research activities/articles -May work specifically with high risk pts -Traditionally worked in hospitals but now found in nursing homes, schools, home care settings and hospice.

c.

Certified Nurse Midwife -Defined by ACNM: independent management of women’s health care especially R/T pregnancy, childbirth, PP period, and care of the newborn -Graduate from a certificate or MSN program -Also provide family planning services, other gynecological needs, and peri/ postmenopausal care -One of the oldest professions -1925-Mary Breckenridge establishes 2

4

3 Frontier Nursing Services-first NurseMidwife to practice in the US -American College of Nurse Midwives was incorporated in 1955 -provide care to women with low incomes, uninsured, and minorities who don’t seek out regular health care -lower rates of cesarean sections in facilities where CNM’s practice d.

Certified Nurse Anesthetists -Defined by AANA: provide --pre-anesthetic assessment --develop and implement plan of care --perform general, regional, local, and sedative anesthesia --manage pt’s airway/pulmonary status --facilitate emergence/recovery from anesthesia --provide follow-up evaluation and care --respond to emergency situations to asst with ACLS, airway, medications -Minimum 24 month programs/MSN with --45 hrs professional aspects --135 hrs anatomy/physiology/ pathophysiology --45 hrs chemistry --90 hrs anesthetic principles --45 hrs clinical/literature review --knowledge of at least 450 anesthetics -80 % practice in an anesthesia care team -20 % practice independent at solo providers

e.

Nurse Consultants -experts in a specific area of nursing -fee for service -may act as expert witnesses -used by corporations R/T developing products/equipment -consult to texts, electronic media, and periodicals 3

B.

Legal and Ethical Issues I.

Litigious nature of this specialty a.

↑ number of malpractice cases involving childbirth issues -OB/Gyn cases 2nd only to surgeries

b.

Minimum standard of care: -care that a reasonable, prudent nurse would provide in the same or similar circumstances

c.

Predominant theory of Liability-negligence -4 elements duty exists breech of duty-standard of care violated injury connection between violation of the standard and the injury

d.

Malpractice lawsuits are based on the assumption that the health care provider failed to meet the professional standard of care and resulted in injury

e.

Alleged injury to fetus, neonate, or mother

f.

Families expecting a healthy child-bad outcome means mistake must have been made

g.

Attribute problem to one or more members of the health care team -frequent unavailability of physician -time frame to communicate may be short

h.

To support expert opinion, need evidence: -hospital procedures -nursing policies -guidelines established by professional organizations -state nurse practice acts -JCAHO

4

6

5 II.

Informed Consent a.

Process by which a pt decides to have a certain medical or surgical procedure -includes knowing and understanding what health care treatment is being undertaken

b.

More than just signing a form

c.

Process by which the physician, nurse, and possibly other health care professionals convey to pt the information for them to decide whether or not to proceed with the course of tx

d.

Without proper consent, provider could be the subject of a lawsuit alleging assault, battery, negligence , or a combination of actions

f.

types of consent: -expressed-oral or written -implied: nurse states here to draw blood and the pt extends her arm --may be used in emergency cases --when pt continues to take tx without objection --during surgery, additional surgery is indicated

g.

Informed refusal -can take place at initiation of tx or any time after start of tx -refusal is valid even after informed consent is given -refusal must be voluntary, uncoerced, and not made under fraudulent circumstances -pt must refuse tx with knowledge and understanding of the refusal -chart should include signed refusal form by pt and nursing notes should include time left, left with whom, risks and consequences of no further tx, and who will be notified

IV.

Common Legal Pitfalls a.

#1 allegation: birth of neurologically-impaired infant

b.

reporting/recording errors: -incomplete initial H & P -failure to observe & take appropriate action -failure to communicate changes in a pt’s condition in a timely manner -incomplete and/or inadequate documentation -failure to use or interpret fetal monitoring appropriately -inappropriate pitocin monitoring/usage -improper sponge/instrument count

c.

almost ¾ of OB/Gyn’s have been sued -most cases will not go trial but be settled out of court

d.

30% have had 3 or more law suits

e.

rising costs of liability insurance

f.

↑ demands for accountability created by expanding the scope of practices

g.

cost containments -shorter hospital stays -use of unlicensed asst personnel -decrease in hospital staff

h.

changes in technology mean needed continued education: EFM

Standards of Care a.

Standardized procedures/policies

b.

supervision of unlicensed asst. personnel KNOW your facility’s Scope of Practice

VI.

Ethical Dilemmas Unique to Perinatal Nursing a.

fetal research-laws vary by state

b.

fetal surgery -i.e.: bilateral hydronephrosis, congenital diaphragmatic hernia -what if mother refuses tx

c.

abortion-Roe vs. Wade (1973) -morning-after pill Plan B-levonorgestrel -lack of estrogen ↓ nausea -medical abortion US: mifepristone + misoprostol France: RU-486

d.

artificial insemination -AIH-husband’s sperm-problem with mother -AID-donor sperm -legal problems-donor relinquishes rights

e.

surrogate childbirth -buying a child-$$$$ -biological mother may refuse to give up the newborn

f.

ART-Asst. Reproductive Technology -IVF-ET -GIFT, ZIFT

g.

embryonic stem cell research/cord blood banking

V.

C.

h.

The Neonate -iatrogenic procedures prolonged use of ventilators O2 therapy -problem: should we save the lives of infants only to have them lead lives of pain, disability, and deprivation? -who decides if major intervention is used -what kind of care do you give or deny the infant to allow him to die with dignity and comfort

i.

The Mother -use life support in irreversible conditions?

Nursing Role a.

Communication -interactions between MD’s, CNM’s, & nurses -was a clear line of communication used -was the chain of command followed -was there informed consent -the better the communication between nurse and pt, less use of litigation -earlier discharges home mean more educational responsibilities for the RN

b.

Use of EFM -first introduced at Yale University in 1958 -In last 25 yrs of use, no ↓ in rate of CP -is partially responsible for ↑ in C/S rate -ordinary part of Intrapartum careconstant threat of legal action

Blood pressure changes 1. blood flow ↓ in the uterine artery during contractions and is redirected to the peripheral vessels 2. peripheral resistance occurs with an ↑ in BP and ↓ of pulse 3. Stage I- ↑ 30 mm Hg systolic ↑ 25 mm Hg diastolic 4. Stage II-↑ BP further 5. Supine hypotension-risk factors multifetal, hydramnios, obesity, dehydration, hypovolemia d. WBC’s 25-30,000 mm secondary to stress, trauma e. hematopoietic 1. desire Hgb at least 11 g/dl Hct 33% or higher 2. ↑ plasma fibrinogen→ ↓ blood coag time→ ↑ clotting factors to protect against hemorrhage but ↑ risk for thrombophlebitis (inflammation of vein in conjunction with formation of a thrombus (blood clot of a vessel or a cavity in the heart)

11

2.

Fluids/electrolytes a. Diaphoresis, ↑ insensible water loss through respirations, NPO status, and ↑ temp b. Voiding may be difficult r/t anesthesia or Pressure from presenting part-↓ sensation of a full bladder c. Proteinuria-↑ in amino acids may exceed capacity of renal tubules to absorb -may be renal damage caused by vasospasms of tubules

3.

GI a. b.

Fluids at tolerated r/t ↓ GI motility and absorption with delay in stomach emptying N & V with diarrhea in labor

4.

Respiratory a. ↑ O2 consumption, ↑ in resp. rate b. hyperventilation →respiratory alkalosis ↑ in pH, hypoxia, hypocapnia (↓CO2) c. 2nd Stage-O2 consumption ↑ → metabolic acidosis uncompensated by resp. alkalosis

5.

Muscular/skeletal a. Fatigue of muscles/strain b. Separation of pubis symphysis -May be related to pregnancy or delivery process (relaxin-polypeptide hormone-secreted in corpus luteum during pregnancy-can relax the symphysis, inhibit uterine contractions, and softens the cervix) c. Breakdown of proteins may lead to proteinuria-albumnin in the urine

12

B.

6.

Neurological a. Euphoria-believe it or not! endorphins-↑ pain threshold and produce sedation b. ↑ anxiety c. partial to total amnesia in 2nd stage

7.

Integumentary a. diaphoresis b. ↑ temperature-may be R/T to maternal efforts or infection c. exacerbation of pruritusmay be related to cholestasis (arrest of the flow of bile) in pregnancy

Fetal Response 1. CV a. ∆ in fetal heart rate (FHR) -maternal hydration N&V ↑ maternal temp insensible water loss -maternal position -medications to mother -placental issues post dates-calcifications smoker/↑ BP-↓ placental size velamentous insertion (umbilical cord attached to the membrane a short distance from the placenta cord compresson -maternal anxiety

13

II.

2.

Pulmonary a. thoracic cavity squeezed -not as much in C/S cases -precipitous deliveries (swift progression of 2nd stage of labor marked by rapid descent/expulsion of the fetus) -may need extra suction b. passing of meconium (1st feces of neonate) may need resuscitation effort

3.

Catecholamines a. epinephrine & norepinephrine-active amines (nitrogen-containing organic compounds) -have effect on CV, neuro, metabolic rate, temp., and smooth muscle b. change R/T ↑ stress of labor speed clearance of fluid

Essential Components of the Birth Process A. Passageway 1. maternal pelvis a. 4 bones -2 innominate (nameless) bones -made up of 3 bones -ilium-iliac crest -ischium-ischial tuberosity -spines-shortest diameter -pubis-symphysis pubis -the sacrum -the coccyx b. False pelvis-the upper pelvis -portion above the inlet

14

c.

2.

True pelvis -inlet -diagonal conjugate-lower border of symphysis pubis-sacral promontory -usually 12.5 cm or greater -obstetric conjugate- also called anterior/posterior diameter -measurement that determines whether presenting part can engage superior strait -usually 1.5-2 cm less than diagonal -midpelvis-cavity, midplane -transverse diameter-interspinous diameter-10.5 cm -outlet -transverse diameter-intertuberous diameter-> 8 cm

Pelvic shapes a. gynecoid-round -50% of women -most favorable -usual mode of birth-vaginal b. android-heart shaped -23% of women -usual mode of birth-cesarean possible forceps-difficult c. anthropoid-oval shaped -24% of women -usual mode of birth-vaginal spontaneous or asst. -may lead to OP position d. platypelloid-flat shaped -3% of women -not favorable for vaginal delivery

15

B.

Passenger 1. Fetal skull a. made up of 6 bones -frontal -2 parietal -2 temporal -occipital b. not fused together-allow for molding, overlapping of bones to pass thru pelvis c. sutures-membranes -frontal -sagittal -lambdoidal -coronal d. fontanels-where membranes intersect -anterior (bregma)-diamond-shaped-2cm by 3 cm -closes by 18 months -posterior-triangle-shaped-1cm by 2 cm -closes by 8-12 weeks e. landmarks -mentum-chin -sinciput-brow -vertex-between anterior/posterior fontanel -occiput-beneath the posterior fontanel 2.

16

7

c. d.

diagnosed using -Leopold’s maneuvers -verify with ultrasound external version-MD attempts to manually rotate the fetus into a cephalic presentation -done in L &D -ultrasound to check fetal/placental position -may use medications to relax uterine muscle -frequently uncomfortable for mother

3.

Fetal Lie a. relationship of long axis (spine) of fetus to long axis (spine) of mother b. primary lies: -longitudinal (vertical)-cephalic, breech -transverse (horizontal or oblique)-shoulder

4.

Fetal Attitude a. relationship of fetal parts to one another b. general flexion -back is rounded -chin flexed onto chest -thighs flexed on the abdomen -legs flexed at the knees -arms crossed over the thorax -umbilical cord lies between arms/legs c. head flexion -biparietal diameter-9.25 cm -suboccipitobregmatic-9.5 cm -occipitofrontal-12 cm -occipitomental-13.5 cm

5.

Fetal position a. relationship of presenting fetal part to 4 quadrants of maternal pelvis b. indicated using a 3-letter abbreviation -1st letter-location of part in pelvis (R or L) -2nd letter-presenting part of fetus (O,S,M) -3rd letter-location of presenting part in relationship to maternal pelvis (A,P,T)

6.

Station a. relationship of presenting fetal part to an imaginary line at the maternal ischial spines: 0 station is at the spines b. negative stations-higher in the pelvis c. positive stations-lower in the pelvis

Powers 1. Primary Powers a. involuntary uterine contractions -start at fundus-thickened uterine muscle layer of upper uterine segment -upper segment thicker so more active -lower segment has less muscle -contractions move down muscle in waves -assessed by: reports from mother RN palpating fundus monitor b. primarily responsible for dilation of cx and descent of fetus -drawing upward of the musculofibrous components of the cervix with fetal head compression lead to dilation (opening) -full dilation (10 cm) marks the end of

d.

e.

2.

the first stage of labor effacement (thinning) -cx usually 3 cm long, 1 cm thick -taken up by shortening of uterine muscle bundles -usually expressed in % uterine contractions -3 phases-increment, acme, decrement -involuntary, rhythmic, intermittent -frequency-beginning of one to the beginning of the next -regularity-usually start irregular then becomes more regular as labor progresses -duration-start to end of contraction -intensity-mild, moderate, strong or strength can be measured with internal monitor (IUPC) with resting tone usually 15-25 mm Ferguson’s reflex -presenting fetal part reaches perineal floor -mechanical stretching of cervix occurs -stretch receptors in vagina trigger exogenous (originating outside an organ) oxytocin release -triggers maternal urge to bear down

Secondary Powers a. bearing down effort at 10 cm -contraction of diaphragm and abdominal muscles while pushing b. ↑ intraabdominal pressure that compresses uterus on all sides c. usually no effect on dilation-important R/T expulsion of fetus and placenta d. better results when await maternal need

D.

to bear down rather than start pushing at 10 cm debate over how to push -valsalva-closed glottis, prolonged push -open glottis pushing -mini pushes prolonged pushing efforts can lead to fetal hypoxia/acidosis and severe maternal perineal lacerations

Placenta 1. Structure a. formed at implantation b. decidua (endometrium during pregnancy) basalis-with the chorion (extraembryonic membrane) forms the placenta c. cotyledon-mass of villi on the chorionic surface of the placenta -15-20 in number d. structure is completed by 12 week e. breaks may occur in placental membrane allowing mixing of maternal and fetal blood-Rh sensitization f. position problems -previa-implanted in lower uterine segment-covers internal cx os -abruptio-separation of placenta from uterine wall -accreta-cotyledons invaded uterine musculature -increta-invasion into the myometrium -percreta-invasion to the serosa of the peritoneum covering of the uterus can lead to uterine rupture

20

Estrogen Stimulation Theory a. estrogen stimulates smooth uterine muscle to contract b. as approaches term, ↑ estrogen, ↓ progesterone (prog. keeps estrogen in check) c. promotes prostaglandin synthesis (also stimulates muscle)

3.

Progesterone Withdrawal Theory a. usually relaxes muscle b. at term-↓ in effectiveness

4.

Fetal Cortisol Theory a. at term, fetus produces more cortisol b. cortisol-(adrenocorticcal hormone) -slows production of progesterone -stimulates prostaglandin precursors

5.

Uterine Distention Theory a. stretching uterine muscles causes irritability leading to contractions b. stimulates production of prostaglandins

23

14

6.

B.

Prostaglandins a. stimulate smooth muscle to contract b. can have production stimulated by various methods -↑ synthesis of PGE2 in amnion c. research varies whether concentration of prostaglandins ↑ in amniotic fluid and maternal blood just before labor onset

Lightening a. fetal descent into the true pelvis b. 2-3 weeks in primigravidas closer to onset of labor in multiparas c. easier to breathe, ↑ need to void

3.

Cervical and vaginal changes a. cervix ripens (softens) and may begin to dilate and efface b. vaginal mucus ↑ with mucus plug being released 1hr, 1day, or even 1 week before start of labor c. occasionally bloody show noted with dark brown or light pink-tinged mucus noted

4.

Persistent low back ache a. R/T relaxation of pelvic joint and descent of fetus b. change of position, warm packs, and warm showers/baths help

24

15

C.

D.

vary

stronger

milder

↑ with walking

↓ with walking

felt in low back then radiates to abdomen

25

16

E.

2.

Dilatation a. opening of cervical os from closed to 10 cm b. due to retraction of cervix into the lower uterine segment R/T uterine contractions and pressure from amniotic sac and fetus c. both dilation and effacement are measured by fingertip palpation or visual inspection with sterile speculum

Station a. using imaginary line at ischial spines, note location of presenting fetal part b. documented from –4 to +4 c. ballottable-when presenting part is floating in and out of the pelvis

Stages and Phases of Labor 1. Prodromal phase a. strong regular contractions without cervical change b. leads to exhaustion R/t inability to sleep c. may need oral/IM medication for rest 2.

Stage 1 (0-10 cm)-has 3 phases a. Early/Latent phase-0-3 cm, 50-90%, -3to -1 -able to walk and talk -able to eat light meals -may be home for most of this phase -involves more cx effacement and less change in fetal position -U/C’s may be 2-10 minutes apart -U/C’s mild by palpation -lasts an average 8 hours for primips -multiparas may have cx dilate to 3 cm days prior to onset of labor

26

17

b.

c.

-ROM may occur during this time Active phase-4cm-7cm, 80-100%, -2 to 0 -U/C’s every 3-5 minutes, moderate by palpation -U/C’s last approx 60 sec -may start to have nausea/vomiting -may ask for enema if impacted to speed descent of fetus -may ask for pain medications -provider may decide to AROM to help speed labor -expect cx to change 1cm every 1-1.5 hrs Transition phase-8-10 cm, 100%, -1 to +1 -U/C’s every 1-3 minutes with ↑ intensity -U/C’s last 45-90 sec long -using breathing techniques not to push too early -may ask for more pain medication -shortest phase-usually 15 min-3 hours with delays R/T medications/infections

Analgesia and Anesthesia Lecture 3 I.

Labor Pain A. Data Collection and Assessment 1. Ask patient comfort level and current pain level -0-10 scale or coping scale -comfort level is when they can participate in ADL’s without the need of pain meds 2. Be aware of cultural differences in response to pain -Asian populations may not exhibit pain or ask for pain medications -Hispanic women may be very stoic until just before the delivery of the baby -Middle Eastern groups may be very vocal in requesting early use of medications for pain 3. Anxiety and fear of the unknown might heighten their level of pain 4. Previous experiences with childbirth or other painful procedures may lead to higher levels of concern about pain management needs 5. Attendance to childbirth classes may aid in the patient’s ability to cope through contractions B.

First Stage 1. Early phase-0-3 cm a. nonpharmacological methods 1. focal points 2. massage/counterpressure 3. hydrotherapy/aromatherapy 4. music 5. breathing techniques 6. Transcutaneous Electrical Nerve Stimulation unit (TENS) 7. heat/cold packs 8. hypnosis 9. changing positions/walk/rocker

pain medications 1. should be discouraged as they could slow the labor process 2. usually orals: percocet vicodin/norco benadryl acetaminophen 3. occasionally IM: morphine with phenergan Active phase-4-7 cm a. may use many of the same non-medication choices as above b. when pain is more intense, usually requests IV medications for fast action -fentanyl -nubain -stadol c. may also request and receive an epidural at this stage in labor Transitional phase-8-10 cm a. may request epidural b. may want to be out of bed and push on toilet to relieve backache c. encourage position changes if possible d. short acting IV narcotics still ok but have Narcan available for infant resuscitation

Second Stage 1. May continue pushing with epidural pump on if efforts are affective 2. May receive local anesthesia for repair of perineal laceration or episiotomy 3. If no epidural is in place, may receive a pudendal block which relieve pain in the vagina, vulva, and perineal regions

D.

II.

Adverse Effects of Excessive Pain A. Physiological effects 1. Effect on cervical change-more in pain, less able to relax and let the labor progress 2. Tensing up against the pain leads to muscle and ligament strains in other parts of the body 3. May not keep properly hydrated and nourished R/T the intensity of the pain 4. Inability to relax back muscles and do deep breathing may lead to difficulty placing epidural catheter B.

III.

Third Stage 1. If placenta is retained, may receive IV pain medications or be moved to OR for twilight sleep 2. For laceration/episiotomy repairs, use of local anesthetics or pudendal block (less common)

Psychological effects 1. “I can’t do it”-ineffective pushing due to fear of pain 2. inability to make decisions R/T pain 3. may become hostile to staff/family R/T inability to cope

Factors Influencing Perception of Discomfort A. Teens and Older Primigravidas B. Cultures/Religions C. Previous experiences with pain D. Support person E. Preparatory classes F. Fetal position-i.e.: OP presentation

V.

Other possible nursing diagnoses 1. Ineffective airway 2. Fluid volume deficit 3. Fetal oxygenation 4. Anxiety R/T pain 5. etc. (see others in book)

Pharmacological Pain Management A. Considerations for the Pregnant Patient 1. What medications you give the mom you give the fetus 2. Maternal concerns that she wasn’t “strong enough” to make it thru without pain meds 3. Need to taper dosage to the patient 4. If previous abuser of medications, will pain med even be effective 5. Cultural beliefs

Analgesics, sedatives, and adjuncts 1. Sedatives may be given in early labor to aid With sleep and anxiety but can lead to a Slowing of the labor progress and noted respiratory depression in the patient along with vasomotor depression of both mom and fetus. 2. Analgesics a. can be systemic crossing the blood/brain barrier as well as the placental barrier b. IV is preferred over IM due to rapid onset but IM medications last longer c. narcotic compounds -Demerol-meperidine -Sublimaze-fentanyl -Stadol-butorphanol -Nubain-nalbuphine -respiratory depression -tachy/bradycardia d. analgesic potentiators -usually antiemetics (Phenergan, Vistaril) -decrease anxiety and apprehension -helps reduce the amount of narcotic needed for relief

C.

Anesthetics (Regional and General) 1. Local block a. usually used on perineal region b. 1% lidocaine used c. injected into skin and subcutaneous d. epinephrine may be added to intensify anesthetic and decrease bleeding 2.

Care of the Lactating Woman A. Physiology of Lactation 1. Female breast has 15-20 lobes containing alveoli (the milk producing cells) 2. alveoli→ductules→lactiferous ducts→nipple 3. ↓ estrogen & progesterone post delivery=↑ prolactin levels which remain above baseline thru duration of lactation (highest level is at day 10) 4. Prolactin: -highest level at day 10 -is produced in response to infant’s sucking -promotes milk production by stimulating alveolar cells B.

Other hormone changes/reflexes 1. Oxytocin responsible for let-down reflex nipple stimulation→pituitary produces oxytocin→ makes cells around the alveoli contract→sends milk to nipple 2. Nipple erection reflex infant cries or rubs against the breast→nipple becomes erect→propulsion of milk

C.

Supply/demand 1. First milk called colostrum a. rich in immunoglobins b. higher concentration of protein and minerals to mature milk but less fat c. promotes growth of Lactobacillus bifides in GI 2. If infant is well nourished, will see 6-8 wet diapers and 3 stools in 24 hours at day 5 of breastfeeding 3. Incomplete emptying can lead to ↓ milk supply 4. watch for infant growth spurts -10 days -3 weeks -6 weeks -3 months -4.5-6 months

Care of the Woman/Neonate Formula-fed A. Formula types 1. commercial formulas primarily cow-milk based but soy and other specialty formulas available 2. may be in powdered, concentrated, or ready to eat B.

Common problems 1. positioning-need to make sure milk covers nipple area 2. warming-never microwave bottle 3. propping-don’t leave infant unattended while feeding

C.

Nutritional requirements 1. first day-only give 7.5-15 ml formula at one time -their eyes are bigger than their stomachs 2. usually feed every 2-4 hours 3. some infants swallow air as they feed-burp them! 4. by 1 week of age, babies will be drinking 700-900 ml in 24 hours *bottle fed because-returning to work, +HIV, mastectomies, adopted infant, maternal medications

Contraception Education A. Considerations for Choosing a Method 1. resumption of sexual activities should wait 2-3 weeks to decrease risk from infection 2. best to use condoms/foam at this time 3. when discussing contraception with your doctor, -action -safety -effectiveness -convenience -availability -expense -personal preference B.

Methods (failure rates listed within 1st year of use) 1. Coitus interruptus (withdrawal) -action-prevents fertilization -safety-no protection from STI’s -convenience/availability-good -expense-N/A

2.

Fertility awareness methods -periodic abstinence-no sex 4 days before and 4 days after ovulation -rhythm-based on 3-4 cycles-use shortest and longest -BBT-sl. ↓ temp before ovulation (0.050C) then ↑ 0.3-0.60C -cervical mucus-ck for changes-amt. and consistency -symptothermal-combo of BBT and cervical mucus -ovulation kits-detect surge in LH that occurs approx. 12-24 hours before ovulation

3.

Barrier methods a. spermicides -action-physical/chemical barrier to sperm -safety-may provide some protection from STI’s -convenience-needs to placed before act -availability-good if thought of in advance -expense-cheap b. condoms -action-physical barrier to sperm -safety-protect against STI’s/HIV if used properly -effectiveness-can ↓ failure rate with use of spermicides -vaginal sheath/condom c. diaphragm -action-mechanical barrier to sperm -safety-see condoms, small amt of cases with TSS-toxic shock syndrome -effectiveness-needs to be fitted to woman’s anatomy, needs to be used with spermicide -convenience-may be placed 6 hours before intercourse but must be left in for 6 hours post act, additional spermicide each time -availability-MD appt -expense-affordable d. cervical cap/sponges -cervical cap needs fitting -must ck position of cap before intercourse -failure rate in parous women-40% -sponge-moisten with water before insertion -have spermicide

50

10 -risk of TSS if not removed after 24 hours 4.

Hormones a. over 30 different formulations b. may have estrogen/progestin or only prog. c. may be oral, subdermal implantation, IM, vaginal d. prevent pregnancy by stopping ovulation or prevention of implantation e. do not protect against STI’s f. not recommended for some women -h/o thromboembolic -smoker -h/o estrogen dependent tumors -h/o CAD -h/o impaired liver -over the age of 35 -HTN g. mini pill (progestin-only) -problems with irregular menses h. injectable progestin-Depo Provera -injected q 11-13 weeks-may need appt. -↑ risk of venous thrombosis i. implanted progestin-Nexplanon -good for 3 years -implanted in arm -no STI protection j. Emergency contraception Plan B-levonorgestrel -needs to used within 72 hours of unprotected intercourse -prevents ovulation/implantation -90% effective -OTC-must be at least 17 years old to purchase Ella-non-hormonal -needs to used within 120 hours -needs Rx -90% effective IUD insertion -99% effective if inserted within 5-7 days

For added protection against pregnancy, you can use more than one method of contraception at a time. For example, many clinicians recommend that when using condoms, spermicides be used as well. If a woman is allergic to spermicides she can use a natural method and a condom and for extra protection. Any of these combinations will reduce the predicted failure rate

1 Nursing Care of the Normal Newborn Lecture 5 I.

Transition to extrauterine life A. Respiratory changes at birth 1. Development of the Lungs a. while a fetus, resp. tract produces fetal lung fluid that expands alveoli b. as term approaches, fluid starts to move to the interstitial spaces c. shift of fluid helps to ↓ pulmonary resistance to blood flow-present before birth and enhanced with breathing of air d. mature lung produces surfactant-no surfactant leads to alveoli collapsing with exhalation -sufficient surfactant by 34-36 weeks 2.

Initiation of respiratory effort a. first breathes require greater pressure to open alveoli b. Chemical-carotid and aortic chemoreceptors respond to changes in blood chemistries: ↓pH, ↓pO2, ↑pCO2—stimulate respiratory ctr. in medulla c. Thermal-skin sensors respond to sudden change in temperature-impulses that stimulate resp. ctr. d. Mechanical-chest compression forces fluid out into upper airways-expelled with birth, pressure released, causes air into lungs—also helped with tactile stimulation, lights, noises

3.

Normal Respiratory Effort a. once alveoli opened, surfactant helps to keep them open b. circulatory and lymphatic systems absorb moved fetal lung fluid c. complete absorption of fluid by 24 hrs-delayed absorption noted in C/S deliveries d. after initial tachypnea, resp. rate is usually between 30-60 breaths/min-may be irregular

4.

Respiratory Distress-reverse of the above

54

B.

II.

Cardiovascular transition 1. air inflates the lungs→↓ pulmonary vascular resistance→ ↓ pulmonary artery pressure→↓ in pressure in the R atrium→↑ pulmonary blood flow to L side of heart→ ↑ the pressure in the L atrium=functional closing of the foramen ovale (functionally closed-1-2 hrs, anatomically closed-30 months 2.

in utero, fetal pO2 is 27 mm HG—after birth, pO2 ∆ to 50 mm Hg in the arterial blood→constricture of the ductus arteriosus—functional closure in 10-24 hrs -permanent closure in 3-4 weeks

3.

pulmonary blood vessels dilate in response to O2 fetal lung fluid moves into the interstitial spaces (any ↓ O2-ductus dilates, pulmonary vessels constrict)

4.

clamping of the umbilical cord closes the umbilical arteries, umbilical vein, and ductus venosus which convert into ligaments-fibrosis within 2 months

Neurological adaptation A. Thermoregulation 1. newborn’s ability to produce heat is often = to adults but have a tendency towards rapid heat loss 2.

heat loss from: thin skin, little sub Q fat, blood vessels close to surface, heat easily transferred from internal to skin

3.

3x the body surface than adults=4x heat loss

4.

flexed position helps preserve heat—problem with premies is poor muscle tone leads to less flex

5.

evaporation-heat loss thru wet skin exposed to air -dry baby immediately at birth

6.

conduction-loss of heat from body surface to cooler surface in direct contact -warm blanket, skin-to-skin contact

55

3

B.

7.

convection-heat transferred to cooler ambient air -keep out of drafts, wrap in blanket with hat on head

8.

radiation-transfer of heat to cooler object not in direct contact with infant -keep cribs away from outer windows

9.

Thermogeneis a. Nonshivering thermogenesis (NST) primarily thru brown fat ( highly vascular fat found only in infants with abundant supply of blood vessels/nerve endings, found at neck, kidneys, adrenals, sternum and intrascapulary region)→heat produced by lipid metabolic activity → warm baby (preterm infants lack brown fat) b. secondarily thru increased metabolic activity in liver, brain, and heart c. shivering begins when thermal receptors in skin detect a drop in the skin temp-rare in neonates

10.

cold stressa. ↑ metabolism = ↑ need for O2 and glucose regardless of gestational age or condition b. if prolonged-leads to resp. difficulty c. O2 consumption diverted from maintaining brain/heart function to thermogenesis d. decreased pulmonary perfusion may lead to an open ductus arteriosus e. hypoglycemia f. fatty acids released = metabolic acidosis g. fatty acids in blood can interfere with bilirubin transport = risk for jaundice

Reflexes 1. Moro (startle) Usually present for first 3-4 months 2.

Palmar, plantar grasp Fingers/toes curl around examiner’s fingers palmar lessens by 3-4 months plantar by 8 months

56

C.

3.

Tonic neck fencing position complete response gone by 3-4 months

4.

Sucking and rooting head turns towards stimulus and sucks

l. m. n. C.

decrease in sperm -hypopituitarism -chronic disease -gonadotropic inadequacy obstruction of the vas deferens or epididymis decreased libido impotency

Components of Fertility 1. Sperm viable in female reproductive tract for up to 48+ hours -fertility potential-24 hrs 2.

Ova viable for about 24 hours -optimum time for fertilization may be only 1-2 hours

3.

Blastocyst must implant within 7-10 days into the hormonally prepared endometrium

4.

Women account for 50% of infertility cases a. male problems-35% b. unexplained factors-15%

5.

Assessment of female infertility a. complete history -duration of infertility -past obstetrical events -sexual history -review medical/surgical history -assess exposure to hazardous substances b. physical exam -assess endocrine systems for abnormalities -visualize secondary sex characteristics -tests to evaluate uterus and fallopian tubes -bimanual exam of organ mobility -lab tests c. testing -HSG-hysterosalpingogram -postcoital test Sims-Huhner test-ck cervical mucus abstain from intercourse for2-3 days performed several hours after ejaculation examine cervical mucus/sperm under 2

192

3 microscope -sperm immobilization antigen-antibody reaction -assessment of cervical mucus spinnbarkeit-the formation of thread by mucus from the cervix when spread on a glass slide and drawn out by a cover glass -U/S dx of follicular collapse -serum assay of plasma progesterone -hormone analysis estrogen, progesterone FSH, LH thyroid -basal body temperature (BBT) biphasic-↑ temp 12-14 days before menses ck temp before rising 0.5-1.00 rise=surge of LH, progesterone ova released 24-36 hrs before ↑ temp intercourse-3-4 days prior to 2-3 after -endometrial biopsy -laparoscopy -U/S 6.

D.

Assessment of male infertility a. H&P b. semen analysis -sperm density-20-200 million cells/ml -may vary day to day-collect over a month -effects of cervical mucus on sperm’s motility and survival -ck sperm’s ability to penetrate an ova

Infertility management 1. Psychosocial a. may need counseling to deal with issues of loss or inadequacy b. dx of infertility may lead to problems with couple’s personal relationship c. discuss alternatives, i.e. adoption 2.

Nonmedical therapies a. water soluble lubricants b. change to boxer shorts c. use of condoms if woman has immunologic 3

193

4 reaction to sperm-will reduce antisperm antibody production 3.

Medical therapies a. ovulatory stimulants -Clomid (clomiphene) stimulates the ovarian follicle -multifetal rates-less than 10% -Parlodel (bromocriptine) inhibits release of prolactin (elevated levels of prolactin have an amenorrhea effect on the body) -Bravelle, Menopur (human menopausal gonadotropin) extremely potent requires daily monitoring daily IM for 7-14 days-first half of cycle incidence of multifetal > 25% -HCG-may be given to induce ovulations after ovaries stimulated with HMG -GnRH (gonadotropin-releasing hormone) used with hypothalamic-pituitary dysfunction or failure to respond to clomiphene b. hormone replacement therapy -use conj. estrogen and medroxyprogesterone c. male tx -thyroid/adrenal gland correction -abx for STI -clomiphene-unsure effectiveness -HCG-stimulates androgens-↑ spermatogenesis

4.

Surgical treatments a. excise ovarian tumors b. removal of adhesions c. hysterosalpingography-may unblock tubes d. if uterine cavity too small to carry pregnancy, no medical tx available-each successive pregnancy enlarges uterus e. may be able to reconstruct uterus R/T bicornuate f. myomectomy g. chemo/thermocautery to eliminate chronic inflammation and infection

Risk for social isolation

The Family Experiencing a Genetic Disorder A. Chromosomal abnormalities 1. Human Genome Project-1990-international effort to map and sequence the genetic makeup of humans a. ELSI-Ethical, Legal, and Social Implications Program-sentinel to prevent discrimination or use of material for eugenic purposes (selective breeding) b. initial sequencing complete 06/00 c. goal-to facilitate study of hereditary diseases and provide potential for altering genes to treat and/or prevent occurrence

5

195

6 2.

Chromosomes a. karyotype-pictorial analysis of chromosomesusually from peripheral blood but may come from any body tissue b. autosomal chromosomes-22 pairs control traits of the body c. sex chromosomes-pair 23 determines sex controls some other traits XX-female XY-male d. dominant gene-their trait is expressed over another (AA or Aa) e. recessive gene-only expressed when another another recessive is present (aa) f. terms-allele-gene that determines a specific trait each trait has a pair of alleles genotype-genetic makeup of an individual phenotypephenotype-expression of gene’s function either measurable or observed homozygoushomozygous-has identical alleles on each chromosome in the same locus hetrozygoushetrozygous-2 different alleles at a given locus

3.

Abnormalities in chromosomal numbers (aneuploidy) a. usually caused by nondisjunction b. occurs during meiosis when pair fails to separate c. trisomy-additional autosomal chromosome -21-Down Syndrome -18-Edwards Syndrome -13-Patau Syndrome (18 & 13-poor prognosis: cardiac & respiratory problems) d. lack of an autosomal chromosome (45)=death of embryo e. mosaicism-some cells have normal #, others missing/having an additional chromosome f. sex chromosome abnormalities -45X-Turner’s juvenile external genitalia undeveloped ovaries short in stature webbing of the neck 6

196

7 impaired intelligence most affected embryos SAB -47XXY-Klinefelter’s poorly developed secondary sexual characteristics small testes-infertile tall, effeminate subnormal intelligence usually present 4.

B.

Abnormality of chromosome structure a. translocation-genetic material moved from one chromosome to another-may create an imbalance of materials no problem if all information present b. additions/deletions gamete produced has too many/too few gene-effect may be mild→severe

Patterns of Inheritance 1. Multifactorial a. combination of genetic and other factors such as environment i.e.: cleft lip/palate, neural tube defects b. malformation may be mild to severe depending on # of genes affected c. tend to occur in families d. some malformations more common in one sex e. polygenic, multifactorial diseases: coronary artery disease, obesity, HTN, psychiatric disorders 2.

Unifactorial-Single-gene disorders a. one gene controls a particular trait, disorder, or defect b. # of unifactorial abnormalities exceed the # of chromosomal abnormalities -50-100,000 genes in 23 chromosomes c. autosomal dominant inheritance -abnormal gene with trait is expressed even with a normal member of the pair-no carriers -mutation of the gene-spontaneous, permanent change -affected individual comes from a family with generations of the disorder-50% chance of have mutant allele if parent was affected 7
