Milia involves distended sweat glands that appear as minute vesicles, primarily on the face. Milk stool usually occurs by the fourth day. The appearance varies depending on whether the newborn is breast or formula fed. Transitional stools usually appear by the third day after the beginning of feeding. They are usually greenish brown to yellowish brown, thin, and less sticky than meconium.
Which statement reflects accurate information about patterns of sleep and wakefulness in the newborn?
- A. States of sleep are independent of environmental stimuli.
- B. The quiet alert stage is the best stage for newborn stimulation.
- C. Cycles of sleep states are uniform in newborns of the same age.
- D. Muscle twitches and irregular breathing are common during deep sleep.
Correct Answer: B
Rationale: During the quiet alert stage, the newborns eyes are wide open and bright. The newborn responds to the environment by active body movement and staring at close-range objects. Newborns ability to control their own cycles depend on their neurobehavioral development. Each newborn has an individual cycle. Muscle twitches and irregular breathing are common during light sleep.
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 observes that a new mother avoids making eye contact with her infant. What should the nurse do?
- A. Ask the mother why she wont look at the infant.
- B. Examine the infants eyes for the ability to focus.
- C. Assess the mother for other attachment behaviors.
- D. Recognize this as a common reaction in new mothers.
Correct Answer: C
Rationale: Attachment behaviors are thought to indicate the formation of emotional bonds between the newborn and mother. A mothers failure to make eye contact with her infant may indicate difficulties with the formation of emotional bonds. The nurse should perform a more thorough assessment. Asking the mother why she will not look at the infant is a confrontational response that might put the mother in a defensive position. Infants do not have binocularity and cannot focus. Avoiding eye contact is an uncommon reaction in new mothers.
Which should the nurse use when assessing the physical maturity of a newborn?
- A. Length
- B. Apgar score
- C. Posture at rest
- D. Chest circumference
Correct Answer: C
Rationale: With the newborn quiet and in a supine position, the degree of flexion in the arms and legs can be used for determination of gestational age. Length and chest circumference reflect the newborns size and weight, which vary according to race and gender. Birth weight alone is a poor indicator of gestational age and fetal maturity. The Apgar score is an indication of the newborns adjustment to extrauterine life.
