Questions And Answers
identity vs identity diffusion ANS✔✔ the period of age where their identity is spread out, not solid/together. They have
diff identities, and not yet able to make sense of who they are
chemical factors to establishing & maintaining respirations ANS✔✔ - stimulation of respiratory centre
- activation of chemoreceptors in carotid arteries
thermal factors to establishing & maintaining respirations ANS✔✔ - decrease extrauterine environment
- stimulate receptors in the skin which stimulates respiratory centre
mechanical factors to establishing & maintaining respirations ANS✔✔ - changes in intrathoracic pressure
- crying of baby to distribute air in the lungs
sensory factors to establishing & maintaining respirations ANS✔✔ - handling or drying the newborn
- using external stimuli to stimulate respiratory centre
- pain associated w/ birth
umbilical veins transport ANS✔✔ oxygenated blood
umbilical arteries transport ANS✔✔ deoxygenated blood
ductus arteriosus is the connection b/w ... ANS✔✔ the pulmonary artery & aorta. It should close within 24-28 hrs, if not,
surgical intervention is needed
foramen ovale is ANS✔✔ connects two atria in fetal heart
, Solution 2024/2025
Pepper
what circulatory changes occur after birth? ANS✔✔ - expansion of lungs to increase BP
- decreased shunting of blood to ductus arteriosus & closure of ductus arteriosus
- increased pressure in L atrium to lower pressure in R atrium
which regulation is most critical to a newborn's survival? ANS✔✔ heat regulation is most critical
why are fetuses more susceptible to hypothermia? ANS✔✔ - larger body surface
- less fat
- no sweating/shivering mechanisms
- blood vessels closer to skin surface
what is goal of care in relation to thermoregulation for newborn? ANS✔✔ maintain a neutral thermal environment, in
which *heat balance is maintained*
what is ideal body temp for newborn? ANS✔✔ 36.4-37.2
body evaporation ANS✔✔ loss of heat when water evaporates from skin & resp tract
body conduction ANS✔✔ direct contact heat loss from body surface to cooler surfaces
body radiation ANS✔✔ proximal heat loss to to surrounding cold objects
body convection ANS✔✔ heat loss from body to surrounding, cooler, air
how to help newborn with evaporation heat loss ANS✔✔ dry baby quickly & remove wet towels/blankets
how to help newborn w/ conduction heat loss ANS✔✔ - pre-warm surfaces baby is going to touch
, Solution 2024/2025
Pepper
- provide covers on surfaces that baby is going to touch (ex; scale)
- skin to skin contact w/ warm surface (ex; body heat of mom)
how to help newborn w/ radiation heat loss ANS✔✔ - keep surfaces baby will touch away from outside walls/windows
- dress baby
- avoid exposing newborn to airdrafts
how to help newborn w/ convection heat loss ANS✔✔ - ensure room temp is adequate (b/w 22-26)
- cover baby's head
- dress baby
what happens when baby experiences cold stress ANS✔✔ oxygen consumption increases, but oxygen uptake to lungs &
tissues decrease, leading to metabolic acidosis
what happens during newborns first period of reactivity ANS✔✔ - lasts up to 30 mins
- HR increases
- RR become irregular
- decrease in motor activity
how long should decreased responsiveness last for post birth? ANS✔✔ 60-100 mins
what happens during newborns second period of reactivity ANS✔✔ - lasts 10 mins - several hours
- tachycardia
- tachypnea
- meconium passed
- increased muscle tone
- skin color change
- mucus production
