Exam 3
Adapting to Extrauterine Life:
After the birth, what must the infant begin?
After the birth, the infant must begin the transition to extrauterine life.
Adapting to Extrauterine Life:
After the birth, the infant must begin the transition to extrauterine life.
How long does transition period last?
Transition period lasts 6 to 8 hours.
Adapting to Extrauterine Life:
What are the Phases of transition period?
The first phase
The second phase
The final phase
Adapting to Extrauterine Life:

Adapting to Extrauterine Life:
When does the final phase of reactivity occur? What occurs at this time?
Occurs between 2 and 8 hours after birth. Meconium often passed at this time
Adapting to Extrauterine Life:
What are the cues to start breathing?
The cues to start breathing are chemical, mechanical, and thermal.
Adapting to Extrauterine Life:
What (having to do with cord) stimulates breathing?
When the cord is clamped and the placenta cannot provide gas exchange, a mild state of hypoxia is created, which stimulates breathing.
Adapting to Extrauterine Life:
What does squeezing through the birth canal do for infants?
Squeezing through the birth canal is a mechanical mechanism to expel fluid in the lungs.
Adapting to Extrauterine Life:
After birth, what does crying help with?
Crying after birth helps absorb fluid in the lungs.
Adapting to Extrauterine Life:
How does a neonates environment change from in the womb to outside the womb?
At birth, the neonate goes from a warm liquid environment to one that is cool and dry.
Adapting to Extrauterine Life:
At birth, the neonate goes from a warm liquid environment to one that is cool and dry.
What does this change in temperature do?
This change in temperature is thought to stimulate breathing
Adapting to Extrauterine Life:
What should nurses assess?
Nurses should assess neonatal respiratory status.
Adapting to Extrauterine Life:
Why is skin to skin important after birth?
Skin to skin with mom- the mom’s temperature will adapt to what the baby needs and regulate all the baby’s systems.
Has a lot of physiologic factors to it.
Adapting to Extrauterine Life:
What are signs of respiratory distress in newborns?
Cyanosis
Apnea
Tachypnea
Intercostal or substernal retractions
Nasal flaring

or another problem
Adapting to Extrauterine Life:
What is the normal breaths per minute a neonate takes?
Neonates typically take 30-60 breaths per minute.
Adapting to Extrauterine Life:
Tachypnea: What may sustained tachypnea indicate?
Sustained tachypnea is abnormal and may indicate respiratory distress syndrome or fluid in the lungs.
May also indicate infection or cardiac or metabolic illness
Adapting to Extrauterine Life:
Intercostal or substernal retractions:
What are retractions?
Retractions are the pulling of the tissue with each breath and indicate reduced pressure inside the lungs, likely because of occlusion of the upper airways
Adapting to Extrauterine Life:
Grunting: When would this occur?
Grunting with expiration occur with a partially closed glottis.
Adapting to Extrauterine Life:
Grunting: What does partial occlusion of glottis cause?
This partial occlusion increases the pressure within the lungs so more oxyygen can diffuse into the bloodstream.
Adapting to Extrauterine Life:
Grunting: How can grunting be recognized?
Grunting may be auscultated with a stethoscope or in more severe cases, heard without assistance
Adapting to Extrauterine Life:
Nasal flaring: What does it do?
Nasal flaring expands the airway and reduces airway resistance
Adapting to Extrauterine Life:
How is the chest and abdomen in the absence of respiratory distress?
The chest and abdomen rise simultaneously in the absence of respiratory distress.
Adapting to Extrauterine Life:
Seesaw breathing: What does it suggest?
Seesaw breathing, like retractions, suggests partial blockage of the airways.
Adapting to Extrauterine Life:
Stridor: What is it?
Stridor, which is an abnormal, high-pitched breath sound, is a sign of upper airway obstruction
Adapting to Extrauterine Life:
Gasping: What is it a sign of?
Gasping is a sign of upper airway obstruction
Adapting to Extrauterine Life:
After birth, what does the first breaths do? What does this result in?
After birth, the first breaths dilate pulmonary vasculature, which results in pulmonary vascular resistance.
Adapting to Extrauterine Life:
What does pulmonary vascular resistance cause?
Pulmonary vascular resistance causes increased blood return from the lungs to the left atrium.
Adapting to Extrauterine Life:
Pulmonary vascular resistance causes increased blood return from the lungs to the left atrium.
What does this lead to?
With the increased blood flow, the left atrium has a higher pressure than the right atrium, causing closing of the foramen ovale.
Adapting to Extrauterine Life
When does the ductus arteriosus close?
The ductus arteriosus closes within a few days or weeks after birth.
Adapting to Extrauterine Life
What does the clamping of the umbilical cord do to blood flow?
Clamping of the umbilical cord causes decreased blood flow to the ductus venosus, which will then begin to atrophy.
Adapting to Extrauterine Life:
How is an infant’s gut? What does the infant lack?
The infant’s gut is sterile and does not have the bacteria needed to make vitamin K, which is used by the body to help blood clot.
Adapting to Extrauterine Life
What is given within six hours of birth to newborn? Why?
An injection of vitamin K is administered to prevent a pathological bleed. (helps with clotting)
Given IM
Adapting to Extrauterine Life
In NYS, what is it illegal for the parents to refuse?
NYS- it is illegal to deny Vitamin K; it must be reported if parents refuse.
Adapting to Extrauterine Life:
What are newborns at high risk for? Why?
Neonates are at risk for hypothermia because they have a high body surface to mass ratio and blood vessels are close to the surface of the skin.
Adapting to Extrauterine Life:
What do newborns not do to produce heat?
Neonates typically do not shiver to produce heat.
Adapting to Extrauterine Life:
How do infants produce heat?
Infants produce heat by metabolizing brown fat stores.

Adapting to Extrauterine Life
What is the stomach capacity of the neonate at birth? What does it increase to in a week?
The stomach capacity of the neonate is about 5 to 10 mL at birth and increases to 60 mL within the first week.
Adapting to Extrauterine Life
