Q

Evaporation

A

loss of heat when liquid converted to a vapour. (moisture vaporization from skin – be sure to dry skin of newborn after birth/bath quickly. The less mature the more evaporative heat loss. Component of insensible water loss.
Thermoregulation – conserve heat in position of flexion to guard against heat loss (diminishes body surface exposed to environment. Also vasoconstriction of peripheral blood vessels. No shivering mechanism!!!

Q

Weight loss

A

5 – 10 % wt. loss in 1st 3 – 5 days is normal due to urine, feces, lungs, increased metabolic rate, intake (colostrum is high fat but not high volume)

Q

What is a newborns first stool called?

A

Meconium
greenish/black because it contains occult blood
early, frequent feeds assist in removing stools (and helps with jaundice)

Q

Iron storage

Study These Flashcards
A

in liver. At birth - Iron storage sufficient to last 4 to 6 months.
Preterm and SGA infants have lower iron stores
Superior bioavailability of iron in breast milk than in formula
Exclusive BF for 6 months is recommended (WHO) – then supplement with iron rich foods
Formula should contain supplemental iron

25
What does colostrum contain
high levels of glucose
26
Vernix caseosa
cheese-like whitish substance after 35 weeks Contains sebaceous gland secretions Emollient (waxy/fatty substance) and antimicrobial properties preventing fluid loss through skin Antioxidant properties Leave vernix intact – decreases skin pH, decreases skin erythema, improves skin hydration
27
Acrocyanosis
when hands & feet are slightly cyanotic due to vasomotor instability (if central and persists, then it is treated)
28
Lanugo
fine hair over face, shoulders and back
29
Eccymosis
edema of face due to face presentation, forceps-assisted birth, vacuum extraction
30
Sweat glands
newborns have sweat glands; term infants do not sweat for first 24 hours.
31
Milia
small white sebaceous glands on newborn face
32
Desquamation
peeling of skin of term newborn begins several days after birth
33
Mongolian spots
congenital birthmarks, bluish black areas of pigmentation over any part of exterior (back or buttocks) or body/extremities.
34
Nevi
Nevus Simplex (aka stork bites, angle kisses) Flat, pink capillary hemangiomas; easily blanched. Fade in 1-2 years
35
Erythema toxicum
transient newborn rash
36
What does bruising increase?
increase risk of hyperbilirubinemia
37
Pseudomenstration
Females mucoid vaginal discharge with slight bloody spotting (increase in estrogen in pregnancy & drop at birth)
38
Male reproductive system
testes descend into scrotum by birth; tight prepuce (foreskin) is normal and may cover the urethral opening. urethra at tip of penis (epispadias and hypospadias are congenital deformations) Smegma – white cheesy substance found under foreskin Epithelial pearls – seen on tip of the prepuce (keratinization in squamous cells) Rugae appear on scrotum (28 – 36 weeks gestation); > 40 weeks – testes palpated in scrotum; rugae cover scrotal sac Scrotum has extra pigmentation due to maternal estrogen Hydrocele – accumulation of fluid around testes that usually resolves without intervention
39
Caput succedaneum
edematous area of scalp (occiput) due to compression of vessels from pressure on cervix (slows venous return)
40
Cephalhematoma
collection of blood between skull bone and periosteum due to pressure against bony pelvis , low forceps, extraction
41
Subgaleal hemorrhage
bleeding into subgaleal compartment (loose connective tissue that connects frontal & occipital muscles and forms inner surface of scalp) assess - boggy scalp, pallor, increased head circ.
42
spine
vertebrae flat and straight. Assess for pilonidal dimple (associated with spina bifida)
43
Extremities
symmetrical, equal in length, 5 fingers, 5 toes, nails
44
Fontanelles
Front (anterior fontanelle) back (posterior fontanelle) Side (sphenoidal fontanelle, mastoid fontanelle)
45
Regulation of physiological system
1. Involuntary – HR, Resps, temp 2. Motor Organization – control random movements, muscle tone, reduce extra activity 3. State Regulation – ability to modulate consciousness Develops predictable sleep and wake states Able to react to stress (self-regulation & communication – crying and consolation) 4. Attention and Social Interaction – stay alert for longer periods; engage socially
46
Areas of assessment
Pink (resps) Warm (temp reg) Attached (attachment to family) Sweet (blood sugar) Organized (maintain optimal state) Clean (infection prevention strategies)
47
APGAR
Appearance Pulse Grimace Activity Respiration
48
Jaundice definition
Jaundice increased level of unconjugated bilirubin in the body. Bilirubin is the yellow product produced by the breakdown of RBC
49
Coagulation of bilirubin
When bilirubin is attached to protein and is unable to be excreted is called uncoagulated bilirubin. Needs to be conjugated to be excreted (enzymes help with this)
50
Physiological Jaundice
Immature liver. Common in newborns. Develops in 2-4 days (can undevelop it)
51
Pathological Jaundice
Within 24 hours after birth – happened right away (encopalopathy and cornictorius). Disease (did not happen naturally). Challenges are more common.
52
Jaundice related to breastfeeding
Jaundice caused by not great breastfeeding. Not optimal feeding. Suboptimal intake jaundice. Response – more breastfeeding is good
53
Interventions for jaundice
Phototherapy, encourage breast feeding Physiological – phototherapy (indirect sunlight at home with unsevere jaundice) Patho – same interventions (more intensive phototherapy) – stays in hospital longer
54
Reflexes
Stepping/walking crawling babinskys Swallow Startle (moro) sucking rooting Grasp
55
First period of reactivity (adaptations of the newborn)
Lasts up to 30 minutes after birth Newborn's heart rate increases to 160 to 180 beats/min Respirations may be irregular: 60 to 80 breaths/min (there may be fine crackles, grunting, nasal flaring, retractions) Baby is alert, spontaneous startle reflex, tremors, crying, movement of head Bowel sounds present, may pass meconium Followed by a decrease in motor activity and sleep
56
Period of decreased responsiveness
lasts 60-100 minutes
57
Second period of reactivity
Occurs 2 to 8 hours after birth Lasts 10 minutes to several hours Tachycardia, tachypnea may occur Meconium commonly passed Increased muscle tone, changes in skin color, and mucus production
58
Newborn assessment
Heart rate - stethoscope or palpation of umbilical cord RR - resp effort and ausc. Muscle tone - flexion and movement of extremities Reflex irritability - response to stimulation Generalized skin colour
