NU 404- unit 6 exam Practice Questions
and Answers
Regarding the transition to extrauterine life, when does the first period of reactivity occur? - Ans:✔✔-30
minutes after birth
Regarding the transition to extrauterine life, when does the second period of reactivity occur? - Ans:✔✔-
2-8 hours after birth
What are the 3 adjustments a baby must make after birth? - Ans:✔✔-respiratory, cardiovascular, thermal
What is chemical initiation of breathing? - Ans:✔✔-when the umbilical cord is cut (utero-placental
circulation ceases)
When the umbilical cord is cut, uteroplacental circulation ceases. This causes an increase in Pco2 and a
decrease in Po2. What does this stimulate? - Ans:✔✔-the medulla (breathing center) and causes baby to
take a breath
The compression of the fetal chest during the delivery process is describes... - Ans:✔✔-mechanical
initiation of breathing
- may have crackles depending on how much fluid

C-S vs SVD - Ans:✔✔-c-section vs. spontaneous vaginal delivery.
- babies born vaginally get the mechanical initiation
- vaginal birth babies should not be as congested.
Initiation of breathing: thermal - Ans:✔✔-changes in the environment stimulate the receptors in skin
- babies need to maintain a neutrothermal temp to prevent cold stress
What temperature should the nursery be? - Ans:✔✔-75
This stimuli, combined with mechanical and chemical, play a role in initiation of breathing in the normal
newborn. - Ans:✔✔-multiple sensory stimuli.
- make sure there is no grunting, flaring, or nasal retractions (GFR)
Environment... - Ans:✔✔-the cooling effect stimulates sensory impulses
- noise, light, pain
- stimulate womb for preemie babies
What are some cardiopulmonary changes for the newborn? - Ans:✔✔-- conversion from fetal to
neonatal circulation (fetal circulation is opposite of our circulation)

- emptying the lungs of fluid (if not emptied...=impaired gas exchange)
- Co2 increased, O2 decreased, sends message to medulla (if something goes wrong, baby will be in
distress)
Surfak (docusate) - Ans:✔✔-lowers the surface tension at the oil-water interface of feces.
- sennoside/laxative/stool softener
- 100mg bid
Contraindications of surfak (docusate) - Ans:✔✔-mineral oil
Symptoms of surfak (docusate) - Ans:✔✔-N/V, abd pain, fecal impaction, appendicitis
What is surfactant? - Ans:✔✔-a surface acting phospholipid (fat) that prevents the alveoli from
collapsing on expiration
- babies bodies makes this
When do alveolar sacs in the lung develop? - Ans:✔✔-at 24 weeks
When are cells of the alveoli changed into type I and type II cells? - Ans:✔✔-by 26-28 weeks
Type I cells are responsible for - Ans:✔✔-gas exchange in the lungs
Type II cells allow for - Ans:✔✔-the production of surfactant

When do the number of type II cells increase concurrently with surfactant productions? - Ans:✔✔-by 35-
36 weeks
- it is possible for fetus to be delivered without resp. distress syndrome by this time
African american girls do not struggle with breathing as much as - Ans:✔✔-boys and caucasians
What do we do if baby is not breathing? - Ans:✔✔-give exogenous surfactant (fatty substance) that
prevents alveoli from collapsing on expiration
Newborn respirations - Ans:✔✔-30-60 breaths/min
- avg. 40
Crying increases respirations to over - Ans:✔✔-60
Characteristics of newborn respirations - Ans:✔✔-shallow irregular breaths with periods of apnea
What is apnea? - Ans:✔✔-pauses in breathing lasting greater than 20 seconds
One of the most crucial adjustments that the newborn must make is - Ans:✔✔-respirations
What is preferred if the baby is in distress? - Ans:✔✔-blow-by
- usually don't put on O2 unless they are in distress
