10 Questions • 11.2% of Exam • This topic covers the various assessments conducted on newborns, including heart rate, respiratory

QUESTION 1
How many periods of reactivity are there?
Answer: 2.
Rationale: 2. The periods of reactivity describe distinct phases of physiological activity following a surgical
procedure. These are typically categorized into the immediate postoperative period and the subsequent recovery period.
QUESTION 2
How long does the first reactivity period last?
Answer: 30 Minutes after birth.
Rationale: The first reactivity period, also known as the first period of reactivity, is the initial phase of a newborn's
development immediately following birth. This period is characterized by vigorous activity and alertness, lasting for
approximately 30 minutes after delivery.
QUESTION 3
During the first reactivity period, how much does the HR increase?
Answer: 160-180.
Rationale: During the first reactivity period, the heart rate (HR) typically increases by 160-180 beats per
minute. This elevation reflects the physiological stress response to the initial stimuli or conditions encountered.
QUESTION 4
What happens to the resp. during the first reactivity period?
Answer: Irregular.
Rationale: During the first reactivity period, which occurs in the first 30 minutes after birth, the newborn's respiratory rate is
typically irregular. This irregularity is characterized by periods of rapid breathing alternating with pauses, reflecting the
immature control of respiration in the neonate.
