OB Exam 3 Flashcards
How long is postpartum phase?
6 weeks, but can be up to months
What is uterine involution?
Uterus size decreasing after birth as expected. Fundus should go down about 1cm/day
What is uterine subinvolution?
When uterus size/fundus not going down as expected
What are the normal ranges of newborn vitals?
HR 110-160
RR 30-60
Temp > 97.6 Axillary
What causes pathological jaundice?
Usually caused by hemolysis
Maternal/NB blood incompatibility (ABO incompatibility)
Sepsis
Trauma
Liver disease
When does pathological jaundice appear?
Within first 24 hours of birth
What causes physiologic jaundice?
Immature liver & extra RBCs
When does physiologic jaundice appear?
After 24 hours of life
Which type of jaundice usually resolves without treatment?
Physiological
Bc it’s due to immature liver
Which type of jaundice can cause neurotoxicity?
Both; acute bilirubin encephalopathy can happen
What treatment is used to treat pathologic jaundice?
Phototherapy; it helps excrete bilirubin faster
What treatment can be given if phototherapy fails to treat jaundice?
Exchange transfusions, but rare.
What are the 4 types of heat loss in NB?
Convection, radiation, evaporation, conduction
When does heat loss by convection occur?
When the room is cold.
Flow of heat from the body to cooler room air
When does heat loss by radiation occur?
When NB is placed near a cold wall/window
Loss of heat from body to cooler solid surface in close proximity (indirect contact)
When does heat loss by evaporation occur?
NB sweating, or right after a bath
Loss of heat when liquid on the body surface evaporates
When does heat loss by conduction occur?
When NB is placed on a cold surface
Loss of heat from body to cooler surfaces in direct contact
Which is more common in NB; hyperthermia or hypothermia?
Hypothermia
What is one way you can prevent heat loss on a NB?
Put hat on their little heads
Which type of heat transfer is occurring with skin to skin contact?
Conduction
What are the s/s of hypoglycemia in infants?
Jitteriness, high pitched cry, irritability, apnea
Can be asymptomatic
How is glucose check performed in infants?
Heel sticks
What level of glucose is considered hypoglycemia in infants?
Less than 40
How is phototherapy done?
Strip newborns naked except for their diapers (covering genitals)
Put goggles on them to protect their eyes
What’s one thing you need to monitor during phototherapy?
SpO2; put pulse ox on them. Goggle can slide down and suffocate them
What is NEC?
Necrotizing enterocolitis. Acute inflammatory disease of the bowel - common in preterm babies
Bowel wall swells and breaks down
What are some signs of NEC?
Increased abd circumference
Bloody stools and vomiting
What’s the possible cause of NEC?
Formula feeding; therefore, to prevent & reduce risk, breastfeed.
How is NEC treated?
NG tube to relieve gas, IV fluids, IV antibiotics, and monitor.
Might need surgery if severe
What medications are given to NB right after birth?
Vitamin K - blood clotting
Erythromycin - eye infection prevention
Hep B
What are the s/s of NAS in NB?
Neuro: seizures, high pitched cry, tremors, hypertonic muscles
GI: poor feeding, V/D
Skin: excoriations, diaper rash
Other: nasal stuffiness, sneezing, frequent yawning
What’s postpartum diuresis?
Peeing and sweating A LOT.
Body is trying to get rid of all the extra fluids from pregnancy.
Tis normal
What scoring tool is used to assess NAS?
Finnegan tool
What’s the treatment goal of NAS?
Stabilize neuro, cardio, GI, social systems
What medication is commonly used to treat NAS symptoms?
Morphine
What are some nonpharmacologic treatment used in NAS babies?
No overstimulation
Rhythmic motion
Swaddling (very tight)
What hormone is associated with postpartum diuresis?
Estrogen
When does postpartum diuresis occur?
Within 12 hours of birth
How long does postpartum diuresis last?
First 2-3 days of:
peeing 3000cc or more each day &
profuse diaphoresis nightly
Why is keeping bladder empty important when it comes to postpartum hemorrhage?
Distended bladder can push uterus up and to the side, leading to excessive bleeding
Why does postpartum put you at a great risk for urinary retention?
Due to swollen uterus and decreased bladder tone
Why is oxytocin given during postpartum?
So uterus can contract and control bleeding. Firm uterus prevents excessive bleeding
Breastfeeding stimulates the release of what hormone from the pituitary gland?
Oxytocin
Mom can experience menopause-like symptoms after birth. Why is that?
Due to estrogen level dropping. It will also cause diminished vaginal lubrication
How long will diminished vaginal lubrication after birth last?
Until ovarian function returns and menstruation resumes
Decrease in what hormone during postpartum result in increased muscle tone in body?
Progesterone
What hormone suppresses ovulation?
Prolactin
What hormone promotes lactation?
Prolactin
Mom might feel cramping and gush of blood while breastfeeding. Why is that?
Because oxytocin is released when breastfeeding. Oxytocin causes contractions, leading to cramps. Contraction also pushes out pooled blood from vagina
Postpartum ovulation in breastfeeding patients begin…
Approximately 6 months
When does ovulation occur in non breastfeeding patients?
7-9 weeks after birth
In non breastfeeding patients, menstruation resumes
12 weeks postpartum
What does BUBBLE HE stand for for postpartum assessment?
B - breasts (breast feeding vs bottle)
U - uterus (fundal height, placement, consistency)
B - bowel and GI function
B - bladder function
L - lochia (color, odor, amount, consistency)
E - episiotomy/other trauma
H - hemorrhoids/hemovascular
E - emotions
What would you recommend breastfeeding mom do when her breasts feel engorged?
