MULTIPLE CHOICE

 

1. A woman gave birth to a healthy 7-pound, 13-ounce infant girl. The nurse suggests that the woman place the infant to her breast within 15 minutes after birth. The nurse knows that breastfeeding is effective during the first 30 minutes after birth because this is the:

a.	Transition period.
b.	First period of reactivity.
c.	Organizational stage.
d.	Second period of reactivity.

 

ANS: B

 

	Feedback
A	The transition period is the phase between intrauterine and extrauterine existence.
B	The first period of reactivity is the first phase of transition and lasts up to 30 minutes after birth. The infant is highly alert during this phase.
C	There is no such phase.
D	The second period of reactivity occurs roughly between 4 and 8 hours after birth, after a period of prolonged sleep.

2. Part of the health assessment of a newborn is observing the infant’s breathing pattern. A full-term newborn’s breathing pattern is predominantly:

a.	Abdominal with synchronous chest movements.
b.	Chest breathing with nasal flaring.
c.	Diaphragmatic with chest retraction.
d.	Deep with a regular rhythm.

 

ANS: A

 

	Feedback
A	In normal infant respiration, the chest and abdomen rise synchronously, and breaths are shallow and irregular.
B	Breathing with nasal flaring is a sign of respiratory distress.
C	Diaphragmatic breathing with chest retraction is a sign of respiratory distress.
D	Infant breaths are shallow and irregular.

3. While assessing the newborn, the nurse should be aware that the average expected apical pulse range of a full-term, quiet, alert newborn is:

a.	80 to 100 beats/min.
b.	100 to 120 beats/min.
c.	120 to 140 beats/min.
d.	150 to 180 beats/min.

 

ANS: C

 

	Feedback
A	The newborn’s heart rate may be about 85 to 100 beats/min while sleeping.
B	The infant’s heart rate typically is a bit higher when alert but quiet.
C	The average infant heart rate while awake is 120 to 140 beats/min.
D	A heart rate of 150 to 180 beats/min is typical when the infant cries.

4. A newborn is placed under a radiant heat warmer, and the nurse evaluates the infant’s body temperature every hour. Maintaining the newborn’s body temperature is important for preventing:

a.	Respiratory depression.
b.	Cold stress.
c.	Tachycardia.
d.	Vasoconstriction.

 

ANS: B

 

	Feedback
A	The primary reason for placing a newborn under a radiant heat warmer is to prevent heat loss and cold stress. Cold stress results in an increased respiratory rate and vasoconstriction.
B	Loss of heat must be controlled to protect the infant from the metabolic and physiologic effects of cold stress.
C	The primary reason for placing a newborn under a radiant heat warmer is to prevent heat loss and cold stress. Cold stress results in an increased respiratory rate and vasoconstriction.
D	The primary reason for placing a newborn under a radiant heat warmer is to prevent heat loss and cold stress. Cold stress results in an increased respiratory rate and vasoconstriction.
