Answer: szsz




- Chemical factors (hypercarbia, acidosis, hypoxia)
sz sz sz sz sz szsz




- Sensory factors (stimuli such as noise, light, touch)
sz sz sz sz sz sz sz sz szsz




- Thermal factors (sudden temperature change)
sz sz sz sz sz szsz




- Mechanical factors (thoracic squeeze during birth clears lung fluid)
sz sz sz sz sz sz sz sz sz szsz




Explanation: These factors collectively stimulate the newborn’s respiratory sz sz sz sz sz sz sz sz




center to initiate and maintain effective breathing at birth.

2. Why does hypoxia, hypercarbia, and acidosis trigger respiration
sz sz sz sz sz sz sz sz




s?: szsz




Answer: szsz




-
sz Hypoxia lowers blood oxygen (PO2) levels and pH, indicating oxygen deficien
sz sz sz sz sz sz sz sz sz sz




cy. szsz




-
sz Carbon dioxide (PCO2) levels rise, stimulating the respiratory center in the m
sz sz sz sz sz sz sz sz sz sz sz




edulla to increase respiratory effort.
sz sz sz sz szsz




Explanation: The medullary respiratory center responds to elevated CO2 an sz sz sz sz sz sz sz sz sz




d lowered O2/pH by triggering spontaneous breathing to oxygenate the blood
sz sz sz sz sz sz sz sz sz sz sz




and remove excess CO2, essential for neonatal adaptation.

3. Periodic breathing in a newborn is not usually associated with a
sz sz sz sz sz sz sz sz sz sz sz




ny change in skin color or HR. How long are these pauses?:
sz sz sz sz sz sz sz sz sz sz sz szsz




Answer: 5-15 seconds sz sz szsz

,Explanation: Periodic breathing is a benign, immature breathing pattern in sz sz sz sz sz sz sz sz sz sz




newborns involving brief pauses, generally up to 10- sz sz sz sz sz sz sz




15 seconds, without oxygen desaturation or cardiac changes.

4. What does each APGAR score mean?:
sz sz sz sz sz sz szsz




Answer: >7 = normal sz sz sz szsz




4-6 = low sz sz szsz




<3 = critical sz sz szsz




Explanation: Scores above 7 indicate good newborn status; scores between 4 sz sz sz sz sz sz sz sz sz sz

6 suggest mild to moderate distress and may require intervention; a score less t

han 3 indicates severe distress and urgent resuscitation is required.

5. When is the APGAR score assigned?:
sz sz sz sz sz sz szsz




Answer: At 1 and 5 minutes after birth sz sz sz sz sz sz sz szsz




Explanation: The APGAR scoring system is a quick and standardized metho sz sz sz sz sz sz sz sz sz sz




d to assess the health and immediate adaptation of a newborn at 1 minute and a
sz sz sz sz sz sz sz sz sz sz sz sz sz sz sz




gain at 5 minutes after birth. This allows healthcare providers to determine if t
sz sz sz sz sz sz sz sz sz sz sz sz sz




he infant needs urgent medical intervention and to evaluate initial responses t
sz sz sz sz sz sz sz sz sz sz sz




o resuscitation efforts.

6. What are the five categories of the APGAR score?:
sz sz sz sz sz sz sz sz sz szsz




Answer: szsz




1. Heart Rate (HR)
sz sz sz szsz




2. Respiratory Rate (RR)

3. Muscle Tonesz sz szsz

5. Generalized Skin Color (coloring)

Explanation: These five criteria are evaluated and scored from 0 to 2 based o sz sz sz sz sz sz sz sz sz sz sz sz sz




n the newborn’s condition immediately after birth to assess their physiological
sz sz sz sz sz sz sz sz sz sz s




z stability.


7. When the APGAR score is <9 at 5 minutes, it is more important to
sz sz sz sz sz sz sz sz sz sz sz sz sz sz s




z stabilize the infant than keep them with mom. T/F? sz sz sz sz sz sz sz sz szsz




Answer: True sz szsz




Explanation: While bonding with the mother is important, an APGAR score sz sz sz sz sz sz sz sz sz sz sz




less than 9 indicates the newborn may need immediate interventions to ensure
sz sz sz sz sz sz sz sz sz sz sz




sz adequate oxygenation and circulation, making stabilization the priority.
