NSG 3500
NSG 3500 - EXAM 4 QUESTIONS AND ANSWERS GRADED A+
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
,NSG 3500
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)
, NSG 3500
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.
