Exam 1 Flashcards
what age is considered an old maternal age?
over age of 35
what does the baby need to become independent in after birth?
- their respiratory system
- their circulatory system
- their ability to thermoregulate
- their ability to produce a source of glucose
how much fluid is in a newborn’s lungs?
about 80-110 mL
why do c-section babies have more fluids in their lungs compared to normal newborns?
because they aren’t being squeezed out and the fluid isn’t being ejected
ductus arteriosus location
between pulmonary artery and aorta
foramen ovale location
between right and left atrium
what is common in a newborn due to their foramen ovale and ductus arteriosus not closing?
they might have murmurs for the first 6 months, then should close
normal newborn heart rate
100-160 beats/min
how is NB circulation changed?
with adequate respiratory function
during sleep, what might be a normal HR?
80-100 beats/min
during crying, what might be a normal HR?
180 beats/min
how long should apical HR be counted?
a full minute
apgar score
initial assessment of vital functions; assess HR, RR, muscle tone, reflex irritability and color
when is an apgar score taken?
at 1 minute after birth and 5 minutes after birth
normal RR for a newborn
30-60 per min
since NB RR are irregular often, what is the best way to check for them?
by watching their abdomen since they are nose breathers
what is important to know about a NB’s temperature immediately after birth?
it drops rapidly
what is the best way to assess for a NB temperature?
axillary; rectal is not advised
normal temp of a NB
97.7-100.0
how long does a NB temp take to stabilize?
24 hours
what is the best way to keep a NB warm besides using a heater?
skin-to-skin (kangaroo care)
what body temperature would be concerning and why?
anything under 97.9; below 97.5 is correlated with poor brain growth and increased mortality
explain brown fat
- metabolized for heat production
- develops at 26-30 weeks
- depletes by 2-5 weeks of age
- more rapidly depleted by cold stress (hypothermia)
what are effects of hypothermia?
- resp. distress
- hypoglycemia
- loss of weight
- jaundice
