Q1 QUESTION 1 OF 107
When is the APGAR score assigned?
Page 1
, RESPONSE
At 1 and 5 minutes after birth
RATIONALE
The APGAR score is a standardized method to assess the physical condition of a newborn
immediately after birth. It is assigned at two critical intervals, allowing for evaluation of the infant's
transition to extrauterine life and response to resuscitation if needed. These designated times
ensure consistent monitoring of the neonate's well-being.
Q2 QUESTION 2 OF 107
What are the five categories of the APGAR score?
RESPONSE
1. HR
2. RR
3. muscle tone
4. reflex irritability (cry)
5. generalized skin color (coloring)
RATIONALE
The APGAR score is a rapid assessment tool used one and five minutes after birth to evaluate a
neonate's physical condition. It quantifies five key physiological parameters: heart rate, respiratory
effort, muscle activity, reflex response to stimulation, and skin coloration. These components help
determine the infant's immediate need for medical intervention.
Q3 QUESTION 3 OF 107
When the APGAR score is <9 at 5 minutes, it is more important to stabilize the infant than
keep them with mom. T/F?
RESPONSE
True
Page 2
, RATIONALE
A low APGAR score at 5 minutes indicates significant neonatal compromise requiring immediate
medical intervention. Prioritizing stabilization ensures the infant's physiological needs are met
before facilitating bonding, which is secondary to life-saving measures. This approach aligns with
emergency pediatric care principles.
Q4 QUESTION 4 OF 107
What does each APGAR score mean?
RESPONSE
>7 = normal
4-6 = low
<3 = critical
RATIONALE
The APGAR score assesses a newborn's physical condition at birth. Scores above 7 indicate a
normal, healthy infant with no immediate concerns. Scores between 4 and 6 suggest a low APGAR,
requiring closer observation, while scores below 3 signify a critical condition needing immediate
resuscitation.
Q5 QUESTION 5 OF 107
What are the 4 factors that influence initiation of the first breath?
RESPONSE
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
RATIONALE
Initiation of the first breath is driven by a combination of physiological and environmental stimuli.
Chemical changes in the neonate's blood, sensory input from the delivery process, a drastic
temperature shift, and mechanical forces from birth all contribute to triggering this critical
respiratory transition.

, Q6 QUESTION 6 OF 107
Why does hypoxia, hypercarbia, and acidosis trigger respirations?
RESPONSE
- 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
RATIONALE
Low blood oxygen (PO2) and a drop in pH stimulate peripheral chemoreceptors, primarily the
carotid bodies, to signal the respiratory center. Concurrently, elevated arterial carbon dioxide
(PCO2) directly stimulates central chemoreceptors in the medulla. This combined signaling
prompts the medulla to initiate or increase respiratory rate to restore homeostasis.
Q7 QUESTION 7 OF 107
Periodic breathing in a newborn is not usually associated with any change in skin color or
HR. How long are these pauses?
RESPONSE
5-15 seconds (approx 3 seconds is norm? P. 298)
RATIONALE
Periodic breathing in neonates involves brief apneic pauses that are physiological and typically do
not cause desaturation or bradycardia. These characteristic pauses, which are distinct from more
concerning apnea, usually last between 5 and 15 seconds. This pattern reflects immature
respiratory control mechanisms in the newborn.
Q8 QUESTION 8 OF 107
What are indicators of respiratory difficulties in the newborn?
