Nokea
Which statement best represents the first period of reactivity in the infant?
- A. Begins when the newborn awakes from a deep sleep
- B. Is an excellent time to acquaint the parents with the newborn
- C. Ends when the amounts of respiratory mucus have decreased
- D. Provides time for the mother to recover from the childbirth process
Correct Answer: B
Rationale: During the first period of reactivity, the infant is alert, cries vigorously, may suck his or her fist greedily, and appears interested in the environment. The infants eyes are usually wide open, suggesting that this is an excellent opportunity for mother, father, and infant to see each other. The second period of reactivity begins when the infant awakes from a deep sleep and ends when the amounts of respiratory mucus have decreased. The mother should sleep and recover during the second stage, when the infant is sleeping.

The nurse should expect the apical heart rate of a stabilized newborn to be in which range?
- A. 60 to 80 beats/min
- B. 80 to 100 beats/min
- C. 120 to 140 beats/min
- D. 160 to 180 beats/min
Correct Answer: C
Rationale: The pulse rate of the newborn varies with periods of reactivity. Usually the pulse rate is between 120 and 140 beats/min. Sixty to 100 beats/min is too slow for a newborn, and 160 to 180 beats/min is too fast for a newborn.
