Newborn Adaptations Flashcards
This deck looks at circulatory system, GI system, renal system
What is the plantar grasp ? When does it typically disappear?
A newborn reflex that occurs when a finger is placed under toes, toes will curl
Disappears at 9-10 mo
What is cutis marmorata (moltling) a result from? (What is the physological response?)
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.
What indicates a properly functioning GI tract in a newborn?
Progressive changes in stool patterns
What is conduction heat loss? what can be done to help prevent/reduce this?
is the loss of heat from the body surface to cooler surfaces in direct contact. The scales used for weighing the newborn should have a protective cover to minimize conductive heat loss.
What is Thrush (Candida Albicans)? How is it treated?
White fungal patches that adhere to mucous membranes of the mouth (cheeks, lips) caused by exposure to Candida albicans
Treated with anti[-fungal drops4
Should treat mother too (nipples)
Risk factors for hydrocele?
Babies born prematurely are at a higher risk for developing hydrocele.
What is “capput succedaneum”? How long does it take to displace/resolve? What does it cross?
Localized edema on the scalp often after a prolonged labour or use of vacuum extraction.
Dissipates in about 3-4 days.
Crosses suture lines
How is Jandice categorized as either physological or pathological?
Traditionally, newborn jaundice has been categorized as either physiological or pathological (nonphysiological), depending primarily on the time it appears and on serum bilirubin levels.
What is the optimal state of arousal?(what is it also known as?)
The optimal state of arousal is the quiet alert state. During this state newborns smile, vocalize, move in synchrony with speech, watch their parents’ faces, and respond to people talking to them
What can failure to pass meconium indicate?
Failure to pass meconium can indicate bowel obstruction related to conditions such as malrotation, small or large bowel atresia, an inborn error of metabolism (e.g., cystic fibrosis), or a congenital disorder (e.g., Hirschsprung disease or an imperforate anus).
Charcteristics of transitional stools?
Appear by third day after initiation of feeding
Greenish brown to yellowish brown
Thin and less sticky than meconium
May contain some milk curds
Physiological jaundice charcteristics and treatment?
Physiological or nonpathological jaundice occurs in approximately 60% of newborns born at term and 80% of preterm infants. It appears after 24 hours of age and usually resolves without treatment.
Treatment for Ankyloglossia?
Can be surgically incised if causing feeding issues
What is tonic neck? When does it typically disappear?
A newborn reflex that occurs when the infant is in a supine position, with head turned to one side, the arm and leg extend on the side to which the head is turned; the opposite arm and leg flex (“fencing” position).
Disappears 6-7 mo
What is a cephalohematoma? How is it different than a capput succedaneum?
A collection of blood beneath the periosteum of the skull.
-Different than a capput succedaneum because it does NOT cross the seture lines
WWhat gender is developmental dysplasia of the hip (DDH) more common in?
More common in females, left hip and firstborns
Can Epispadias occur with girls? or does it only occur in males?
Can also happen in girls where urethral opening is located elsewhere and there are other abnormalities of the genitalia
How many mL is excreted via the renal system within the first few days?
Excretes 15-60 ml/kg (first few days)
What is not routinely measured in a healthy newborn?
Unless there is a specific indication, BP is not routinely measured in the healthy newborn.
What structure carrys blood from the Patent, carrying of blood from hypogastric arteries to placenta?
Umbilical areteries
What is Lanugo? When does it disaperar?
Soft, downy hair on the body, particularly on the face, shoulders and back.
Disappears over the first few weeks of life.
What is Erytheum toxicum (Newborn Rash)? When is it common? What is the treatment?
Very common in 1st week.
Small white or yellow papules or vesicles on the skin.
No clinical significance. No treatment
What are expected/normal physical examiniation for newborn breasts?
Breasts may be enlarged, in both boys and girls, and may secrete milk (Galactorrhea).
(This is a result of high exposure to maternal estrogen in utero. This usually dissipates in a few weeks)
What is “Pseudomenstruation”? Treatment?
a vaginal discharge composed of mucus mixed with blood > may be present during the first few weeks of life>.requires no treatment
What serum level of bilirubin is classified as hyperbilirubinemia?
Although there is no consistent definition for neonatal hyperbilirubinemia, the Canadian Paediatric Society suggests that an unconjugated bilirubin greater than 340 mcmol/L in the first 28 days of life constitutes hyperbilirubinemia
How many voids is expected per day for the first 5 days after delivery? How many voids ia expected per day at 1 week of age?
1 void/day for first 5 days
At 1 wk., 6-8 voids/day
What is “molding”?what is it a result of?
Elongated shape of the skull as a result of overlapping of cranial bones during birth
What structrue allows blood to pump from the right ateria to the left atria in newborns?
Foramen ovale
How should newborn ears be?
Ears should be aligned with the outer canthi of the eyes.
What “symptpms” indicate the need to measure/take a newborns BP?
In the presence of cardiovascular symptoms such as tachycardia, murmur, abnormal pulses, poor perfusion, or abnormal precordial activity, four extremity BP and preductal and postductal oxygen saturation levels may be taken
When does a cephalohematoma typically occur? When does it disappear? What may happen as a result?
Appears on day 2 or 3 and disappears in weeks or months.
Jaundice may result.
In utero, what is the low-resistance pathway for gas exchange?
The placenta
Characteristcs of formula fed stools?
pale yellow to light brown, firmer consistency, odour more characteristic of a normal stool
What is the babinski reflex? When does it typically disapear?
Fanning and hyperextension of all the toes and dorsiflexion of the big toe, occurs when the lateral aspect of the sole is stroked from the heel upwards and across the ball of the foot.
(Positive babinski:when the big toe bends up and back to the top of the foot and the other toes fan out - This can mean that you may have an underlying nervous system or brain condition that’s causing your reflexes to react abnormally)
Disappears 2 years of age
At what biliroubin level is jaundice considered to be pathological?
Jaundice is usually considered pathological or nonphysiological if it appears within 24 hours of birth, if total serum bilirubin levels increase by more than 100 mcmcol/L in 24 hours, and if the serum bilirubin level exceeds 256 mcmol/L at any time
What is ANKYLOGLOSSIA? Who is it more common in?
*Tounge tie
A ridge of frenulum tissue attached to the underside of the tongue, causing a heart-shape at the tip of the tongue
More common in boys, genetic component
