UNIT-7-CARE-OF-THE-NEWBORN Flashcards
includes a review of the mother’s pregnancy
history, physical examination of the infant, analysis of laboratory reports such as hematocrit and blood type if
indicated; and assessment of parent-child interaction for the beginning of bonding.
Assessment of a newborn or neonate (a baby in the neonatal period)
begins immediately
after birth and continued at every contact during a newborn’s hospital or birthing center stay, early home visits, and
well-baby visits
Assessment
Examples indicating achievement of outcomes
concerning newborns (Pillitteri, 2010) are:
- The infant establishes respirations of 30 to 60 per minute.
- Infant maintains the temperature at 97.8° to 98.6° F (36.5° to 37° C).
- Infant bottle feeds or breastfeeds well with a strong sucking reflex
a very significant and a highly vulnerable time due to critical transition from intrauterine to extrauterine life
The first 24 hours
It involves thoroughly drying the baby with warm towels or cloths while being
placed on the mother’s abdomen or in her arms or also known as
(unang yakap)
One of the first is to check
for the
Apgar.
It is the test that evaluates the newborn’s condition at 1 minute and 5 minutes after birth. The
healthcare provider or midwife and nurses will evaluate these signs and give a point value
Apgar.
The following are the key components of the immediate care for the newborn in the nursery
- Anthropometric Measurements including
- Bathing – Oil bath/ warm water bath
- Cord Care
- Dressing/ Wrapping - mummified
- Eye prophylaxis – Crede’s Prophylaxis
- Footprinting / Identification
- Get APGAR to score – 1 & 5 mins
- HR, RR, Temp, BP.
To initiate airway & breathing,
we may gently suction the mouth, and the nose of the baby gently & quickly
use a bulb syringe or suction catheter. We must start by suctioning the mouth first, then the nose to prevent
aspiration. Stimulate crying by rubbing the back, then position properly- side-lying and provide oxygen when
necessary
is the most crucial among newborns. T
The initiation of respiration and airways
blood – low oxygen, high carbon dioxide, and low pH initiates impulses that excite the
respiratory center in the medulla
Chemical factors:
blood – low oxygen, high carbon dioxide, and low pH initiates impulses that excite the
respiratory center in the medulla.
Chemical factors:
sudden chilling of an infant. From a warm environment to a cooler atmosphere. The abrupt
changes in temperature excite sensory impulses on the skin then transmitted to the respiratory center.
Thermal factor
tapping, flicking the sole of the feet, and gently rubbing
the baby’s back, trunk, and extremities. Prolong tactile stimuli is harmful to the baby
Tactile stimulation may assist in initial respiration
According to Pillitteri (2010), the following are the procedures to initiate breathing and respiration among
newborns:
a. Support the head and remove secretion
b. Removal of secretion by bulb syringe
c. Proper suctioning with a catheter
Turn baby’s head to side: to facilitate drainage & aspiration precautions, A NB should be positioned to
the R side to increase pressure to the L side of the heart. This position favors the closure of Ductus
Arteriosus and Foramen Ovale and gastric emptying, thereby preventing the reflux of gastric contents
and suctioning of mouth 1st, then nose (obligating nasal breather).
Rationale:
stimulation of the nasal
mucosa will cause reflex inhalation of pharyngeal material into the trachea and bronchi, causing
aspiration
Suctioning is always mouth before the nose to prevent
Gasp reflex
t or f
A 4 – 5sec but not more
than 10 seconds in terms of babies, less than 5 sec in preterm babies, gently & quickly
t
Prolonged and
deep suctioning can cause
Hypoxia, bradycardia, laryngospasm
If not effective, requires ____ to open the airway with deep suctioning, an endotracheal
tube is inserted & oxygen can be administered by a positive pressure bag & mask with 100% O2
40-60 b/min (full-term).
LARYNGOSCOPY
If meconium stained, never give O2 with pressure, it can cause
atelectasis.
is a scoring system that doctors and nurses use to assess newborns for one minute and five
minutes after birth
Apgar score
determine the general condition of the newborn.
1st minute –
determines the capacity of the newborn to adjust to extrauterine life (most important).
5 minute –
it will depend on the 5-minute APGAR score
10/15 minutes – optional –
s the failure to cry within 30 secs because the mother receives Demero
Asphyxia Neonatorum
is
the antidote of Demerol.
Narcan
The following are the areas of assessment for APGAR Score

Preterm
According to Ballard and Dubowitz, the following are the signs of preterm (Pillitteri, 2010):
- Plus, frog legs or lax position.
- Hypotonic – prone to respiratory infection
- Scarf sign – elbow passes midline.
- Square window – wrist 90-degree angle
- Heal to ear sign
- Anterior transverse crease
- Abundant lanugo
- Prominent labia minora and clitoris
is initiated by Lung expansion and pulmonary ventilation
Circulation
dilates
the pulmonary vessels; pulmonary vascular resistance decreases, and systemic resistance increases, thus
maintaining blood pressure. P
Increased blood flow
results in closure of ductus venosus & inferior vena cava at 4th day of life
Pulmonary artery pressure → ↓ blood flow
results in the closure of ductus arteriosus soon after birth
Pulmonary artery pressure → ↑pO2
involves the umbilical cord, and the 2 umbilical arteries carry the
unoxygenated blood back to the placenta for oxygenation.
fetoplacental circulation
is the one responsible for oxygenation of the blood
PLACENTA
- ↑ pCO2 - ↓ PO2. The cry will initiate lung expansion that will increase
pressure from the left to the right side of the heart.
TANGENTIAL FOOT SLAP
should be strong,
vigorous & crusty cry
The normal cry of a baby
high-pitched cat-like cry, which will
lead to failure to close
CRI – DU- CHAT SYNDROME
PROPER POSITIONING
- ® SIDE LYING POSITION
it increases the pressure on the left side of the
heart, thus facilitating the closure of the foramen ovale. Failure to close might result in the atrial
septal defect (ASO) and Patent ductus arteriosus
PROPER POSITIONING - ® SIDE LYING POSITION
s just a temporary or palliative surgery that creates a shunt between the aorta and pulmonary
artery so that the blood can leave the aorta and enter the pulmonary artery, and this oxygenating the lungs and
return to the left side of the heart, then to the aorta then to the body
Blalock-Taussig
The blood volume of the newborn depends on the placental blood flow. Average for a full-term infant is
80 to 85ml/kg of the body weight after birth, the total blood volume is 300 ml, but it depends on how
long the umbilical cord clamping is delayed or if the cord is milk 100 ml can be added.
Hematopoietic System.
Hematopoietic System.
Average for a full-term infant is
___ of the body weight after birth
80 to 85ml/kg
Hematopoietic System.
the total blood volume is
300 ml
Changes occur in the total body water volume, extracellular fluid volume during the transition from fetal
to postnatal life. The infant’s fluid is 73% of total body weight, while adults’ fluid is 58% of total body
weight
Fluid and Electrolytes.
The infant’s fluid is ____ of total body weight, while adults’ fluid is ___ of total body
weight
The infant’s fluid is 73% of total body weight, while adults’ fluid is 58% of total body weight
The ability of the newborn to digest absorbs and metabolizes but has limited function. Enzymes are
adequate to handle proteins and simple carbohydrates. The liver is the most immature organ.
Gastrointestinal System.
is the most immature organ.
The liver
Functional deficiency of the kidney is to concentrate urine and cope with the condition of the fluid and
electrolytes stress, such as dehydration or a concentrated solute load. A 200-300 ml total volume of urine
for 24 hours by the end of the first week and an average of 20 voidings per day total of 15ml. Colorless,
odorless urine with a specific gravity of 1.02. NBS involves several types of testing. Phenestix test is a
diagnostic that uses a fresh urine sample (diapers) and mixed with ferric chloride. If (+), there will be a
presence of green spots at the diapers. Guthrie test is another test for PKU and is the one that mostly
used. The specimen used is the blood, and it tests if CHON is converted to an amino acid.
Renal System.
is a
diagnostic that uses a fresh urine sample (diapers) and mixed with ferric chloride
Phenestix test
Present at birth but has an immature function. The epidermis and dermis are loosely bonded to each
other and very thin. Rete pegs or the anchoring of the epidermis to the dermis is not yet developed. Still,
the Sebaceous gland is active in fetal life and early infancy because of the high level of maternal
androgens.

evident in newborns such as labia hypertrophied, the breast is engorged, and the milk’s secretion is
present a few days of life to 2 months, pseudomenstration from the sudden drop of estrogen and
progesterone level.
Maternal sex
incompletely integrated but sufficiently developed to sustain extrauterine life.
Nervous system
These are crucial during transition because they stimulate initial respiration and help maintain acid-base balance and partially regulate temperature control.
Autonomic nervous system.
The newborn infant displays extraordinary sensory development
and an astonishing capability for self-organization in social interactions. Infants’ muscles are
very firm and resilient. They could engage when triggered but cannot control them. The
stretches and wiggles, but their movements are uncoordinated.
