⩥ When the APGAR score is <9 at 5 minutes, it is more important to
stabilize the infant than keep them with mom. T/F?
Answer: True
⩥ What does each APGAR score mean?
Answer: >7 = normal
4-6 = low
<3 = critical
⩥ What are the 4 factors that influence initiation of the first breath?
Answer: Chemical factors: hypercarbia, acidosis, and hypoxia
Sensory factors: overwhelming stimuli aids in transition
Thermal factors: drastic change in temp aids in transition
Mechanical factors: thoracic squeeze through birth causes fluid release
and replacement with air
⩥ Why does hypoxia, hypercarbia, and acidosis trigger respirations?
,Answer: - hypoxia causes blood oxygen (PO2) levels to rise and pH to
drop
- carbon dioxide levels (PCO2) begin to rise and prompt the resp center
within the medulla to initiate breathing
⩥ Periodic breathing in a newborn is not usually associated with any
change in skin color or HR. How long are these pauses?
Answer: 5-15 seconds (approx 3 seconds is norm? P. 298)
⩥ What are indicators of respiratory difficulties in the newborn?
Answer: - apnea (no breathing for more than 20 seconds)
- expiratory grunting
- wheezing
- nasal flaring
- retractions
- use of accessory muscles to breathe when at rest
- high RR
⩥ What are the five changes for successful cardiopulmonary adaptation?
Answer: - increased aortic pressure
- decreased venous pressure
- increased systemic pressure
- decreased pulmonary pressure
, - closure of foramen ovale, DA, and DV
⩥ What is the HR when baby is first born?
Answer: 160-180 and then 30 min later it goes to 120-160
⩥ The baby cannot become hypoglycemic from heat loss. T/F?
Answer: False.
⩥ How do newborns respond to cold?
Answer: They burn brown adipose tissue since they cannot shiver to
maintain warmth
⩥ What can the nurse do to regulate temperature in the newborn?
Answer: - skin-to-skin contact with mom and warm blankets
- dry head and place cap on baby
- warp baby in two warm blankets
- place unwrapped baby under radiator and monitor temp
- monitor axillary temp
- keep newborn away from drafts
babies can regulate their temp better in 24-48hrs
