ATI: Infants Flashcards
Physical Development
- lose 5% to 10% body birth weight in first few days, but should regain it by the second week
- weight gain is about 5 to 7 oz per week in the first 6 months (should be doubled)
- measurements of crown-to-rump length, head-to-heel length, head circumference, and chest circumference are key indicators of appropriate growth
- head molding (overlapping of skull bones) present
- fontanelles are palpable
Reflexes
startling, sucking, rooting, grasping, yawning, coughing, plantar and palmar grasp, and Babinski
>confirm presence or absence of expected reflexes to monitor for appropriate neurological development
Body Position
- flexed at rest
- movement should involve all 4 extremities equally, but can be sporadic
Sleep
- sleep patterns can be reversed for several months (daytime sleeping and nighttime wakefulness)
- average 15 hours of sleep time each day
Cognitive Development
- learn to respond to visual stimuli
- use cry as a form of communication
- cry patterns can change to reflect different needs
Psychosocial Developement
-interactions with caregivers affect psychosocial development
>positive= promote nurturing and attachment
>negative= hinders appropriate attachment
-most newborns can mimic the smile of the caregiver by 2 weeks of life
Posterior Fontanelle Closes When?
by 2 to 3 months of age
Anterior Fontanelle Closes When?
by 12 to 18 months of age
Weight
- double by 4 to 6 months of age
- triple by 12 months of age
Height
- grow 2.5 cm (1 in) per month in the first 6 months
- grow 1.25 cm (0.5 in) per month until the end of the first year
Head Circumference
- increases 2 cm per month during first 3 months
- 1 cm per month from 4 to 6 months
- 0.5 cm per month from 6 to 12 months
Teeth
6 to 8 teeth erupt in the infants mouth by the end of the first year
- use cold teething rings, OTC teething gels, and acetaminophen or ibuprofen
- use a cool, wet washcloth to clean the teeth
- do not give infants a bottle when they are falling asleep; prolonged exposure to milk or juice can cause dental caries
Cognitive Development: Piaget
Sensorimotor Stage (birth to 2 years)
- separation is the sense of being distinct from other objects in the environment
- object permanence develops at 9 months of age
- recognition of symbols
Object Permanence
- develops at 9 months
- process of knowing that an object still exists when it is hidden from view
Language Development
- responds to noises
- vocalizes with “oohs” and “aahs”
- laughs and squeals
- turns head to the sound of a rattle
- begins to comprehend simple commands
- pronounces single-syllable words
- begins speaking two- and then three- word phrases
Psychosocial Development: Eriskson’s
Trust vs. Mistrust (Birth to 1 Year)
- infants trust that others will meet their feeding, comfort, stimulation, and caring needs
- infants reflexive behavior (attachment, separation recognition/anxiety, and stranger fear) influences their social development
When Does Attachment Begin?
infant begins to bond with their parents
- develops within the first month, but begins before birth
- process is optimal when parents are in good health, have positive feeding experiences, and receive adequate rest
When Does Separation Recognition Begin?
- occurs during the first year as infants recognize the boundaries between themselves and others
- learning how to respond to people in their environment is the next stage of development
- positive interaction with parents, siblings, and other caregivers help establish trust
When Does Separation Anxiety Begin?
- develops between 4 to 8 months of age
- infants protest loudly when separated from parents, which can cause anxiety for parents
When does stranger fear become evident?
between ages 6 to 8 months; when infants are less likely to accept strangers
Self-Concept Development
by the end of the first year, infants distinguish themselves as separate from their parents
