tachycardia, tachypnea, and meconium passes
RATIONALE
The second period of reactivity in neonates is characterized by a return to a more stable state after
the initial transition. During this phase, which can last several hours, the infant may experience
increased heart rate (tachycardia) and respiratory rate (tachypnea) as their body continues to
adjust.
Q8 QUESTION 8 OF 89
Normal newborn HR:
CORRECT ANSWER
120-160
RATIONALE
The normal heart rate for a newborn infant typically ranges between 120 and 160 beats per minute
