Q

What is cutis marmorata (moltling) a result from? (What is the physological response?)

A

Results from NB undeveloped nerve and blood vessel systems.

When the skin cools, the blood vessels near the surface contract and dilate alternately. The red color is produced when the vessels expand and the pale part is produced when the vessels shrink.

Jaundice, the visible yellowish colour of the skin and sclera, is likely to appear when bilirubin levels exceed 85 to 102 mcmol/L (Blackburn, 2018). Jaundice is generally noticeable first in the head, especially in the sclera and mucous membranes, and progresses gradually to the thorax, abdomen, and extremities. The degree of jaundice is determined by serum total bilirubin measurements.

Characteristics of the anterior fontanelle?How long do they remain open for?
Diamond-shaped “soft spot”. Remains open up to 18 months to allow the brain to grow.
52
What is "Hydrocele"?
A collection of fluid surrounding the testes in the scrotum *Normally, this sac closes itself and the body absorbs the fluid inside during the baby’s first year. However, this doesn’t happen for babies with a hydrocele.
53
Symptoms of developmental dysplasia of the hip (DDH)?
Signs of DDH are asymmetrical gluteal and thigh skinfolds, uneven knee levels, a positive Ortolani test, and a positive Barlow test. The hips are inspected for symmetry. Gluteal and thigh skin folds should be equal and symmetrical, and legs should be of equal length.

What are 3 common charatceristics of the newborns GI system?
1.) Bowel sounds are usually heard after birth 2.) Mucus membrane of the mouth is moist and pink 3.) Hard & soft palates are intact Occasionally born with 1 or more teeth
59
What is evaporation heat loss? What can be done to help prevent/ reduce this?
is the loss of heat that occurs when a liquid is converted to a vapour. In the newborn, heat loss by evaporation occurs as a result of vaporization of moisture from the skin. This heat loss is intensified by failing to completely dry the newborn directly after birth or with bathing. The less mature the newborn, the more severe the evaporative heat loss. Evaporative heat loss, as a component of insensible water loss, is the most significant cause of heat loss in the first few days of life.
60
What are lower set ears chacrteristics of?
Lower set ears are characteristic of many syndromes and internal organ abnormalities involving the renal system.
61
When the first meconium is passed, what shoul dbe noted?
1.) Time 2.) Colour 3.) Character of the newborns fiest stool
62
What is cutis marmorata (moltling)? What is a response to?
Lacy patterns of blood vessels under the skin Normal physiological response to cold temperature.

Characteristics of meconium?When is it usually passed?
Greenish black, tarry consistency; usually passed within 12 to 24 hours of birth; almost all do so by 48 hours
64
Risk factors for Hypospadias?
(The urethral opening is on the underside (ventral aspect) of the penis at any place along the shaft) Risk factors: Mothers >35, obesity, fertility or hormone treatments
65
The fetal system has high (blank) pulmonary resistance and low (bank) systemic vascular resistance
The fetal system has high pulmonary vascular resistance (PVR) and low aortic systemic vascular resistance (SVR)
66
Charcteristics of normal urine for a newborn?
Pale straw coloured
67
When do Telangiectatic Nevi" fade?
Fades in first and second years of life
68
What is "Hypospadias"? How is it treated?
The urethral opening is on the underside (ventral aspect) of the penis at any place along the shaft Tx:Surgery – baby should not be circumcised as foreskin might be needed for repair
69
What is a torticolis? What does it result in?
Tightness of the sternocleidomastoid muscle Results in the newborn’s head tilting to one side
70
What is convection heat loss/how does it occur? What can be done to help decrese this?
is the flow of heat from the body surface to cooler ambient air. Because of heat loss by convection, the ambient temperature in the newborn care area should range between 22° and 26°C and newborns in open bassinets are wrapped to protect them from the cold. A cap may be worn to decrease heat loss from the newborn’s head.
71
What is the palmar grasp ? When does it typically disappear?
Newborn reflex that occurs when a finger is placed in the newborn’s palm. The newborn’s fingers curl around the examiner’s finger Disappears 2-3 mo
72
What is the netural thermal environment?
The neutral thermal environment is the ideal environmental temperature that allows the newborn to maintain a normal body temperature to minimize oxygen and glucose consumption
73
What is Developmental Dysplasia of the Hip (DDH)? How is it treated?
Condition where socket of hip joint does not form properly – too shallow so that ball of hip is loose and can come out Treated with Pavlik harness-
74
What is sucking? When does it typically disappear?
A common newborn reflex that occurs when an object placed in the newborn’s mouth or anything touches the lips will elicit this reflex. Disappears after 3 months
75
What is the "stepping" reflex? When does it typically disapear?
When held upright with one foot touching a flat surface, the newborn puts one foot in front of the other and “walks” Disappears at 2 months
76
What structure carrys blood from the Patent, carrying of blood from placenta to ductus venosus and liver?
Umbilical Vein
77
What causes capput succedaneum?
(it is localized edema on the scalp often after a prolonged labour or use of vacuum extraction) The slower venous return causes an increase in tissue fluids within the skin of the scalp, and an edematous swelling develops.
78
How many voids is expected at 1 day of age?
1 day of age a minimum of 1 void is expected
79
What connects the umblical vein to the inferior vena cava?
The ductus venosus connects the umbilical vein to the inferior vena cava
80
What is moro? When does it typically disappear?
A newborn reflext thats elicited when the newborn is startled or lifted slightly above the crib and then suddenly lowered. The newborn’s arms straighten, hands move outward (fingers fan out), thumb and forefinger form a “C” and knees flex. Slowly the arms return to the chest Disappears 5-6 mo
81
What is rooting? When does it typically disappear?
COmmon newborn reflex thats elicited when the side of the newborn’s mouth or cheek is touched. The newborn turns toward that side and opens the lips Disappears 3-4 months
82
What is radiation heat loss? What can be done to prevent this?
is the loss of heat from the body surface to a cooler solid surface not in direct contact but in relative proximity. To prevent this type of loss, cribs and examining tables are placed away from outside windows and care providers need to avoid exposing the newborn to direct air drafts.
83
What are "Mongolian Spots"? What ethinicities do they more commonly occur in?
Bluish black areas of pigmentation commonly noted on the back and buttocks. Occurs more frequently in ethnicities from Asia, Africa, Indigenous North America
84
Risk factors for Jaundice?
Among the factors that increase the risk of hyperbilirubinemia, prematurity is the most significant one. Prematurity affects liver and brain metabolism and albumin binding sites, placing preterm and late preterm newborns at greater risk for hyperbilirubinemia. Newborns of Asian and Indigenous backgrounds have higher bilirubin levels. Breastfeeding newborns are at greater risk of hyperbilirubinemia.
85
What is ALIPES EQUINOVARUS (CLUBFOOT)? what may it be due to?
A painless malposition of the feet – can be turned in. May be due to intrauterine positioning, environmental or genetic factors
86
What is thermoregulation? Within what kind of range do newborns attaempt to stabilize their temaptures?
Thermoregulation is the maintenance of balance between heat loss and heat production. Newborns attempt to stabilize their core body temperatures within a narrow range.
87
When is a cephalohematoma usually the largest?
A cephalohematoma is usually largest on the second or third day, by which time the bleeding stops.
88
What is the "galant" reflex? When does it typically disapear?
This reflex is observed when the infant, while prone and stroked along the spine, causes the pelvis to turn to the stimulated side disappears at 1 month
89
What is "Leukorrhea"? What is it caused vy?
can also occur – whitish discharge from vagina – caused by mother’s estrogen in newborn
90
If the systolic is more than (blank mmHg) in the (blank extremities) further (blank) may be needed
. If the systolic pressure is more than 10 mm Hg higher in the upper extremities than in the lower extremities, further diagnostic testing may be needed.
