PPN 301 - Newborn
Assessment and Care Exam
Questions and Answers 100%
Solved
identity vs identity diffusion - ✔✔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 - ✔✔- stimulation of
respiratory centre
- activation of chemoreceptors in carotid arteries
,©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
thermal factors to establishing & maintaining respirations - ✔✔- decrease
extrauterine environment
- stimulate receptors in the skin which stimulates respiratory centre
mechanical factors to establishing & maintaining respirations - ✔✔- changes in
intrathoracic pressure
- crying of baby to distribute air in the lungs
sensory factors to establishing & maintaining respirations - ✔✔- handling or
drying the newborn
- using external stimuli to stimulate respiratory centre
- pain associated w/ birth
umbilical veins transport - ✔✔oxygenated blood
umbilical arteries transport - ✔✔deoxygenated blood
ductus arteriosus is the connection b/w ... - ✔✔the pulmonary artery & aorta. It
should close within 24-28 hrs, if not, surgical intervention is needed
foramen ovale is - ✔✔connects two atria in fetal heart
,©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
what circulatory changes occur after birth? - ✔✔- 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? - ✔✔heat regulation is
most critical
why are fetuses more susceptible to hypothermia? - ✔✔- 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? - ✔✔maintain
a neutral thermal environment, in which *heat balance is maintained*
what is ideal body temp for newborn? - ✔✔36.4-37.2
body evaporation - ✔✔loss of heat when water evaporates from skin & resp
tract
, ©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
body conduction - ✔✔direct contact heat loss from body surface to cooler
surfaces
body radiation - ✔✔proximal heat loss to to surrounding cold objects
body convection - ✔✔heat loss from body to surrounding, cooler, air
how to help newborn with evaporation heat loss - ✔✔dry baby quickly &
remove wet towels/blankets
how to help newborn w/ conduction heat loss - ✔✔- pre-warm surfaces baby is
going to touch
- 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 - ✔✔- 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 - ✔✔- ensure room temp is
adequate (b/w 22-26)
