NSG 3500 - EXAM 4 QUESTIONS AND
ANSWERS 100% VERIFIED.
When is the APGAR score assigned? - correct answer
At 1 and 5 minutes after birth
What are the five categories of the APGAR score? - correct
answer
1. HR
2. RR
3. muscle tone
4. reflex irritability (cry)
5. generalized skin color (coloring)
When the APGAR score is <9 at 5 minutes, it is more important
to stabilize the infant than keep them with mom. T/F? - correct
answer
True
What does each APGAR score mean? - correct answer
>7 = normal
4-6 = low
<3 = critical
What are the 4 factors that influence initiation of the first
breath? - correct 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? - correct 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? -
correct answer
5-15 seconds (approx 3 seconds is norm? P. 298)
What are indicators of respiratory difficulties in the newborn? -
correct 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? - correct 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? - correct answer
160-180 and then 30 min later it goes to 120-160
The baby cannot become hypoglycemic from heat loss. T/F? -
correct answer
False.
How do newborns respond to cold? - correct answer
They burn brown adipose tissue since they cannot shiver to
maintain warmth
What can the nurse do to regulate temperature in the newborn?
- correct 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
Blood volume is determined in large part by the timing of the
umbilical cord clamping. T/F? - correct answer
True
