Newborn

Question 1

common ages for developmental tasks

Answer 1

TBD

3 months- fixation visual

Question 2

contraindications to BF

Answer 2

o Infants born to HIV+ mothers

o Galactosemia- infant cannot metabolize galactose

Question 3

voiding after birth

Answer 3

• Voiding after birth: 6-8x per day by day 6; by day 3, no more meconium in stool; at least 3-4 stools per day by day 6

Question 4

physiologic jaundice

Answer 4

• Physiologic Jaundice: usually noticed on second or third day of life- bilirubin peaks on day.3 or 4

Question 5

BF jaundice

Answer 5

 Early in first week of life when milk supply is low lack of enteral intake
 Difficult to distinguish between physiologic jaundice

Question 6

breastmilk jaundice

Answer 6

 Begins first 4-7 days of life but doesn’t peak until 10-14 days
 Protein in milk potentially deconjugates bilirubin in intestinal tract
 Can persist up to 12 weeks but rarely becomes concerning

Question 7

hemolysis

Answer 7

o Breakdown of RBC- hemoglobin is metabolized to unconjugated bilirubin
o Antibody-positive hemolysis: direct Coombs or DAT positive
 Rh incompatibility (mother is negative and baby is positive)
 ABO incompatibility (mother is type O and baby is type A or B)
o Antibody negative occurs in infants with RBC membrane defects

Question 8

non hemolytic RBC breakdown

Answer 8

o Extensive bruising from birth trauma, large cephalohematoma, polycthemia

Question 9

• Risk factors for severe hyperbilirubinemia (TSB> 95th perentile)

MAJOR

Answer 9

 Pre discharge TSB or TcB in high risk zone
 Jaundice observed in first 24h
 Blood group incompatibility with positive DAT
 GA 35-36 weeks
 Previous sibling received phototherapy
 Cephalohematoma or significant bruising
 Exclusive breastfeeding
 East Asian

Question 10

minor risk factors HB

Answer 10

	Pre discharge level in the high intermediate risk zone
	GA 37-38 weeks
	Jaundice observed before discharge
	Prev sibling with jaundice
	Macrosomic infant of diabetic mother
	Maternal age >25y
	Male gender

Question 11

Direct bilirubin= fractionated bilirubin

Answer 11

go over GBS guidelines

Question 12

pathologic vs physiologic jaundice

Answer 12

pathologic- occurs within 24 hours
conjugated hyperbilirubinemia

vs physiologic

Question 13

GBS guidelines
