Growth and developmentinfant – Toddler – preschooler – school-age – adolescent Flashcards
Exam 1
Growth
Increase in physical size
How is growth plotted on a graph?
Plotted on standardized growth charts to assess adequate growth for age and gender
How are children typically seen on growth charts?
Children typically remain in same percentiles over time. Major deviations warrant investigation
What kinds of growth charts exist?
Specialized growth charts for children with specific diagnoses (i.e. Downs Syndrome) and breastfeeding infants
Development
Sequential process by which infants and children gain various skills and functions
What is used to assess development?
Utilize screening tools to assess (i.e. Denver II, Ages and Stages, etc.)
Maturation
Increase in functionality of various body systems or developmental skills
When are the two greatest growth changes in pediatrics?
Adolescence and first year of life are two greatest growth changes in pediatrics.
For newborn and infants, how do you measure physical growth?
Weight
Height
Head circumference
Average weight of a newborn
Average is 7.5lbs
How does weight of newborn change in 4-6 months?
Doubles by 4-6 months

4 inch gain by 1 year
List of reflexes of a newborn (hint: there are 9)
- Moro,
- Root,
- Suck,
- Asymmetric Tonic Neck,
- Plantar Grasp
- Palmar Grasp,
- Step,
- Babinski.
- Grasp
What happens to baby reflexes?
Diminish over first few months (except Babinski which takes 1 year)
What does newborn reflexes give way to?
Gives way to protective reflexes (righting and parachute reactions)
During the first few months of life, reflexive behavior is replaced by what?
Purposeful action
Respiratory rate of newborns
30 -60 in newborn
How much is respiratory rate of a 12 month old?
20-30 breaths
Why is respiratory rate higher in infants than adults?
Babies have high metabolic demand so respiratory rate is faster
When does respiratory system reach full maturity?
Respiratory system do not reach full maturity until about 7 years old
How does nasal passages of newborns compare to adults?
Nasal passages are narrower
How does trachea and chest wall of newborns compare to adults?
Trachea and chest wall are more compliant
How does bronchi and bronchioles of newborns compare to adults?
Bronchi and bronchioles are shorter and narrower
How does alveoli of newborns compare to adults?
Significantly fewer alveoli
What happens to the heart size in the first year of life?
Heart doubles in size in the first year
What happens to the average pulse rate of a newborn? and 1 year old?
Average pulse rate decreases from 120 to 140 in the newborn to about 100 in the 1 year old
What happens to blood pressure of newborn?
Blood pressure steadily increases, from an average of 60/40 in the newborn to 100/50 in the 12 month old
How are the peripheral capillaries in newborns?
Peripheral capillaries are closer to the surface of the skin, making the newborn and young infant more susceptible to heat loss
What becomes more effective in newborns as they grow?
Thermoregulation becomes more effective
GI system: Tongue of new born; why is it this way?
Tongue is larger relative to oral cavity size; it must be able to latch onto the nipple for the infant to feed
GI: Stomach of newborn
Stomach capacity increases as the infant grows
When does first primary teeth erupt? What teeth are they? How do teeth emerge?
First primary teeth erupt between the ages of 6 and 8 months
(incisors).
Teeth emerge in a predictable pattern
How is the stool of infants in the first year of life? Why?
Consistency and frequency of stools change over the first year of life based on intake (breast or bottle) and age (i.e. meconium)
Genitourinary and Integumentary Systems: Infants are more susceptible to what?
Infants more susceptible to dehydration
Genitourinary and Integumentary Systems: How is urine of newborn and infant?
Frequent urination with low specific gravity (not concentrated until glomeruli mature)
Genitourinary and Integumentary Systems: What is seen on newborns usually?
Lanugo and vernix may be seen in the newborns
Genitourinary and Integumentary Systems: How is the skin color of newborns?
Acrocyanosis is normal in the newborn and decreases over the first few days of life
Genitourinary and Integumentary Systems: How is the skin of newborns?
Skin is relatively thinner than that of adults with peripheral capillaries more superficial
Hematopoietic and Immunologic Systems: What happens to iron stores during pregnancy?
Maternal iron stores are transferred to the fetus throughout the last trimester of pregnancy.
Hematopoietic and Immunologic Systems: What happens to premature infants iron stores?
Therefore, premature infants miss this transfer and are at increased risk of iron deficiency anemia.
Hematopoietic and Immunologic Systems: How do newborns receive immunity?
Newborns receive immunity through the placenta and
utilize those antigens for first 3-6 months of life until they synthesize their own IgG, reaching adult levels by 9 months.
When do infants reach adult levels of IgE?
reaching adult levels by 9 months.
Three Developmental Theorists:
- Erikson
- Piaget
- Freud
Erikson Developmental Theory INFANT stage:
Trust v Mistrust (birth to 1 year)
Trust v Mistrust
Caregivers respond to infant’s basic needs, this creates a sense of trust in the infant.
Infants realized they are separate from their caregivers. They learn to tolerate small amounts of frustration and trust that although gratification is delayed, it will eventually be provided
Piaget Developmental Theories INFANT STAGE:
Sensorimotor
Sensorimotor
Infant uses senses and motor skills to learn about the world
Freud Developmental Theories Infant stage:
Oral stage: birth to 1 year
Oral stage
Pleasure is focused on oral activities; feeding and sucking
Newborn and Infant sensory development: Sight
View objects 8-15 inches away, prefer human face
Newborn and Infant sensory development: Sight- when does binocularity occur?
Binocularity – ability to fuse 2 ocular images into 1, begins at 6 weeks and established by 4 months. Color vision, distance, tracking by 7 months.
Newborn and Infant sensory development: Hearing
Intact at birth
Newborn and Infant sensory development: Smell and Taste:
Newborns can smell and prefer sweet tastes
Newborn and Infant sensory development: Touch:
Touch: Most important
