NSG 3500 - Exam 4 Questions With
Complete Solved Solutions.
When is the APGAR score assigned? - Answer At 1 and 5 minutes after birth
What are the five categories of the APGAR score? - 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? - 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)
, - 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
Blood volume is determined in large part by the timing of the umbilical cord clamping. T/F? -
Answer True
_____________________ is seen in most newborns as oxygenated blood is shunted to central
