Ob Exam 3 Flashcards
Normal Newborn vitals
110-160 = normal
85-100 sleeping
180 = crying
Temp newborn
97.7 - 99-5
Newborn RR
30-60
Pathological jaundice
Underlying diseases like infection or blood incompatibility
Appears before 24 hours of age
Pathological Tx
Phototherapy
Physiologic Jaundice
Considered benign
Increased bilirubin lvls 72-120 hours after birth w/ rapid decline to 3mg/dL 5-10 days after birth
Physiologic jaundice cause
Hyperbilirubinemia
Physiologic jaundice TX
Increasing feeding
Monitor that bilirubin too I’d assume
Jaundice findings and cause
Typically see yellow sclera which means maternal newborn blood is incompatible
Worst blood comparability
Mom O- and baby A+
Jaundice lab tests
Monitor serum bilirubin test Q4 hrs
Assess blood compatablity
Review HGB + HCT
Coombs tests reveals presence of antibody coated RH positive RBCs in newborn
Coombs Test
reveals presence of antibody coated RH positive RBCs in newborn
Phototherapy
Check electrolytes for DHD?
Thermoregulation
Critical to survival
Hypothermia is very common and bad
Know the types of heat loss
Heat loss types
Convection
Conduction
Radiation
Evaporation
Convection
Heat loss through air currents so like the ac vent or in direct line of fan
Conduction
Heat loss through DIRECT contact of another surface
Radiation
Loss of heat from cool surface NEARBY
So like windows and ac vents nearby
Evaporation
Heat loss through evaporation of moisture on skin
Preventing Convection
Place bassinet out of direct like of a fan
Swaddle infant and keep head covered
Procedures should be done under radiant heat source
Room temp should be 72-78 degrees
Preventing Radiation
Keep newborn and examination tables away from windows and air conditioner
Evaporation prevention
Rub infant dry with warm sterile blanket
Expose only one body part at a time when bathing
No bath until body temperature is 97.7 degrees
Conduction Prevention
Pre heat radiant warmers
Warm stethoscope before applying
Pad a scale before weighing
Place newborn directly on parent’s chest
Hypoglycemia
< 40 mg/dL during first 3 days of life
Normal Newborn Glucose
40-60 mg/dL
Newborn hypoglycemia Risk factors:
■ Maternal DM
■ Preterm infant
■ LGA or SGA
■ Stress at birth (cold stress, asphyxia)
most important intervention to prevent baby from hypothermia
Head cap is most important to keep heat in
HYPOGLYCEMIA S/S IN INFANTS:
Jitteriness/tremors
BG < 40
Cyanosis + apnea
weak cry
Flaccid muscle tone
poor feed
*CAN be asymptomatic
Hypoglycemia Nursing Care:
Heel Stick for glucose monitoring
initiate early feedings - frequent PO or gavage
IV dextrose (glucose) for symptomatic/ unstable newborn
Phototherapy nurses role
placed under the light with eye mask
newborn undressed
NO lotions or ointments
Baby must have pulse oximeter on incase goggles slip down
reposition Q2 hours
Check lamp energy w/ photometer
Remove from phototherapy q 4 h and unmask newborns eyes
NEC
Necrotizing Enterocolitis (NEC)
S/S of NEC
Abdominal tenderness/bloating (LARGE STOMACH)
*BLOODY STOOL, VOMITING, ABDOMINAL DISTENTION
How to reduce NEC?
Breastfeeding reduces risk
What causes NEC
complication of preterm infants
formula can cause this
describe NEC
necrosis & perforation of bowel –> bowel death– especially high risk if given formula–r/t immature gut
S/S of NEC? test Q
BLOODY STOOL, VOMITING, ABDOMINAL DISTENTION
NEC TX
Stop feedings
Inserting an NG tube
IV fluids and nutrition to replace breast milk/formula
IV ABX
Monitoring w/ x-rays, CBC, blood gas
Isolation precautions
Surgery to remove dead intestinal tissue
Newborn medications given after birth
Hep-B
Erythromycin
Vitamin K
Hep B Requirements
Vaccine with parental consent
Vitamin K Requirements
Single IM injection in vastus lateralis to ensure proper start of coagulation cascade
Erythromycin Requirements
eye ointment within 1-2 hours of birth (mandatory in the US, apply 1-2 cm ribbon in lower lids of eyes)
If born preterm with eyes shut, wait until eyes open
Vitamin K purpose
prevents bleeding
Erythromycin eye ointment purpose
prevents eye infections
Hep B vaccine big to know
NEEDS MOTHER’S CONSENT
What is NAS
Neonatal Abstinence Syndrome
CNS S/S of Neonatal Abstinence Syndrome
o High-pitched, shrill cry
o Seizures
o Hypertonic muscles
o Stiffness
CNS S/S test Q of NAS
TREMOR, EXCORIATIONS ON THE SKIN, HIGH PITCHED CRY, VOMIT
NAS: S/S of Metabolic/Resp/Vasomotor
o Nasal congestion w/ flaring
o Sneezing
NAS GI S/S?
o Poor feeding
o Regurgitation/projectile vomiting
o Diarrhea
when does POSTPARTUM DIURESIS occur?
Diuresis occurs within 12 hours after birth
What is POSTPARTUM DIURESIS?
Diaphoresis and diuresis occur within the first 2-5 days after delivery; rid the body of excess fluid during the last part of the pregnancy
POSTPARTUM DIURESIS times
Weight loss due to lochia, delivery, and diuresis of about 19lb during the first 5 days after delivery
increased urinary output begins within 12 hrs
Normal postpartum diuresis
Urine output of 3000 mL or more each day for first 2-3 days (NORMAL)
Profuse diaphoresis (sweating) nightly for first 2-3 days (NORMAL)
POSTPARTUM DIURESIS - complication?
Urethral swelling and decrease bladder tone
= high risk for urinary retention
What happens if the bladder is distended?
Can push the uterus UP and to the SIDE, leading to excessive bleeding (postpartum hemorrhage, boggy fundus)
–> KEEP THAT BLADDER EMPTIED
Breastfeeding and how it affects hormones
Oxytocin can promote bonding and calmness during BF (love hormone)
HICH HORMONE IS PRODUCED DURING BREASTFEEDING FOR MILK PRODUCTION?
Prolactin - stimulates milk production
Stimulated by baby sucking
POSTPARTUM FUNDUS AND HOW IS IT MEASURED:
Level of umbilicus 12 hrs after birth
1 finger breadth or cm per day
if it doesn’t go down consider hemorrhage
if it’s to the side, have them empty their bladder
Fundus is to the side
EMPTY BLADDER
fondus doesn’t go down
probs hemorrhage
Fondus height after delivery?
1 hour after delivery, the fundus (top portion of the uterus) should rise to the level of the umbilicus
UTERINE INVOLUTION
Involution occurs with contractions of the uterine smooth muscles; returning the uterus to its pre-pregnant state
UTERINE SUBINVOLUTION
Subinvolution is a medical condition in which the uterus DOES NOT return to its normal size
HOW LONG IS THE POSTPARTUM PHASE:
6 weeks (when mother’s body has returned to its pre-pregnant state)
Lochia?
post-birth uterine discharge that contains blood, mucus, and uterine tissue
Amount is similar to a heavy menstrual period about 2 hrs post-delivery and will decrease gradually at a consistent rate
Stages of Lochia
o Lochia Rubra
o Lochia Serosa
o Lochia Alba
Lochia Rubra
dark red color - can last 2-3 days after delivery
bloody consistency, fleshy odor, can contain small clots, transient flow increases during BF and upon rising, can last 2-3 days after delivery
Lochia Serosa
pinkish brown color –> lasts approx. 2 weeks after delivery
serosanguineous consistency, can contain small clots and leukocytes
Lochia Alba
yellowish white cream color that lasts up to 6 weeks
fleshy odor, can consist of mucus and leukocytes
Assessing Lochia
Amount
color, odor, and consistency
Pads can be weighed to give better estimate
Amounts of Lochia
Scant: less than 2.5 cm
Light: 2.5- 10 cm
Moderate: more than 10 CM
Heavy: one pad saturated within 2 h
Abnormal amount of Lochia
Excessive blood loss: one pad saturated in 15 min or less, or pooling of blood under buttocks
Lochia foul odor
abnormal indicates infection
C section amount of bleeding
C-Section: amount of bleeding will be decreased
