Q

Blood volume of full term newborn

A

85-100 ml/kg, depending on time of cord clamp

32
Q

Benefits of late and early cord clamping

A

Late - extra blood volume opens lungs, enriches iron stores, and increases pulmonary perfusion
Early - Extra blood volume from late increases heart workload and risk for jaundice

33
Q

Newborn blood facts

A

More erythrocytes and higher hemoglocin and hematocrit (H&H) but shorter life span for RBCs.

34
Q

Infant Hematocrit

A

> 65 indicates risk for respiratory distress and jaundice

35
Q

What is given after birth?

A

Vitamin K 1 mg 1 hour after birth.

36
Q

Pallor indicates

A

Hypoxia or anemia

37
Q

Plethora

A

Ruddy skin color that indicates polycythemia. Confirmed by hematocrit >65 and at risk for jaundice.

38
Q

When does the infant stomach empty? (poop)

A

2-4 hrs after feeding. Perstalsis is very rapid

39
Q

Effect of long intestines in newborns

A

prone to water loss with diarrhea

40
Q

When are bowel sounds present in newborns?

A

within 1st hr

41
Q

Newborn digesion

A

Cannot digest complex carbs, no saliva production, but enzymes and saliva begin to appear by 36 weeks.

42
Q

Function of liver in infant

A

Blood glucose maintenance (stored as glycogen in liver), conjugation of billirubin, iron storage.

43
Q

Glucose for newborn

A

45-60. Hypo or Hyper is anything below or above.

44
Q

Signs of hypoglycemia

A

Jitteriness. sweating, tachypnea, low temperature, HI PITCHED CRY, irritability, coma. Can also be asymptomatic.

45
Q

Where to heel stick?

A

Very bottom of heal, farthest side.

46
Q

Why are infants at risk for jaundice?

A

Liver is immature and cannot conjugate billirubin.

47
Q

What happens when hematocrit is >65?

A

Hemolysis of excessive erythrocytes releasing billirubin. causes Jaundice!

48
Q

Difference between Physiologic and Pathologic jaundice

A

Physiological: result of IMMATURE LIVER and RBC hemolysis. Normal in infants 1st 24 hours of life, 3-4 days after delivery. BEGINS IN THE FACE AND MOVES DOWN THE BODY.
Pathlogical: Occurs within 24 hours of life and the billirubin increases above physiological jaundice.

49
Q

Breastfeeding jaundice

A

Occurs with inadequate intake, poor hydration, and delay in elimination.

50
Q

True Breast milk jaundice

A

Occurs within 4-7 days from substances in brreast milk that interfere w/ conjugation. Treated by discontinuing breastfeeding, pumping milk, and phototherapy.

51
Q

Thermoregulation interventions

A

Dry infant, radiant warmer, skin to skin

52
Q

Medications given after birth

A

Eye (Erythromycin) antibiotic ointment, vitamin K injection in vastus lateralis to reduce risk of hemorrhagic disease

53
Q

Normal vitals

A
Temp: 97.7-99.5
Pulse: 120-160
Resp: 120-160
BP: 70/45 (not usually taken)
Glucose: 40-60
54
Q

Normal measurements

A

Weight: 2500-4000gm, 5’8 oz - 8’13 oz
Length: 48-53 cm
Head: 33-35.5 cm
Chest: 30.5.33cm

55
Q

LGA and SGA

A

Large/Small for gestational age. Large is above 90th percentile, Small is below 10th percentile

56
Q

Surfactant role

A

Keeps alveoli open during first breath. produced after 22 weeks, lines and protects alveoli and reduces surface tension. By 34 weeks, there is enough to breath without difficulty

57
Q

Respiratory assessment

A

COUNT FOR 1 FULL MINUTE. rapid, shallow, irregular respirations with pauses from 5-10 seconds are normal

58
Q

Signs of respiratory distress

A

Tachypnea, retractions, flaring of nostrils, grunting, seesaw respiration (asymmetric chest), Central Cyanosis

59
Q

Difference between Central and Acrocyanosis

A

Central involved the lips, tongue, and trunk while acro is only legs and feet.

60
Q

What openings close after birth?

A

Ductus arteriosus and Ductus venosus, and foramen ovale

61
Q

How often do you assess cardiovascular (heart sounds, pulses)?

A

q30 mins until stable for 2 hrs

62
Q

How do infants lose heat?

A

Evaporation, Conduction (something cold touches skin), Convection (drafts, A/C) , Radiation (heat transferred to cooler objects without skin contact).

63
Q

How do infants maintain heat?

A

Moving (flexion), oxidation of brown fat,

64
Q

Effect of cold stress (hypothermia-ish)

A

Requires more o2/glucose, increased metabolism (to maintain heat), decreased Surfactant/glycogen/brown fat.

65
Q

Effect of Hyperthermia

A

Requires more o2/glucose, causes vasodilation, water/fluid loss

66
Q

How often is temperature assessed?

A

q30 mins until stable for 2 hrs

Thin cord = Poorly nourished

Yellow-brown/green tinge = Meconium release prior to birth.
