Exam 1: Growth & Development Flashcards
Growth (Definition and 5)
Increase in physical size
- Children grow by either length and height (linear) or weight
- When measuring children under 2, measure length from head to heel to while child is laying down
- Measure weight using scale
- Growth is cepholocaudal and proximal
- Up to 3 years old, plot growth on a chart that includes head circumference
Neurological Growth
- Most rapid period of growth is in utero (imp to look at mother’s prenatal health because of this)
- Prefrontal cortex continues to develop until ~25 years old
Development
Increase in capacity or function
- One part of development may take precedence over another part, Ex: toddlers; gross motor skills take precedence over language skills
Cephocaudal
From head to toe
Proximodistal
Growth from inside out
Body Mass Index (5 and calculations)
- Assess underweight, overweight and at risk for overweight.
- Used for ages 2 to 20 years of age
- Is gender and age specific
- BMI decreases during preschool years then increases to adulthood
- Doesn’t account for muscle mass composition
( weight in lbs ) \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ x703 (height in in.) x (height in in.) (weight in kg) \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ x10,000 (height in cm) x (height in cm)
Weight status categories (4)
- Underweight: less than 5th percentile
- Healthy weight: 5th percentile to less than 85th percentile
- Overweight: 85th to less than 95th percentile
- Obese: equal to or greater than 95th percentile
Why is BMI for age a useful tool?
- It provides a reference that can be useful beyond puberty
- It compares well to lab measurements of body fat
- It can be used to track body size throughout life.
Infancy (birth to 1 month and first 6 months) Weight
Birth to 1 month: 2700 – 4000g (6-9lbs) gains
First 6 months: About 5-7oz./wk.
Infancy (birth to 1 month and first 6 months) Length
Birth to 1 month: 48-53 cm (19-21in.) increases
First 6 months:2.5cm/mth
Infancy (birth to 1 month and first 6 months) Head Circumference
Birth to 1 month: 33-35cm increases
2cm per month for first 3 months, then 1 cm/month until 6 months of age
Infancy Chest Circumference
2-3cm less than head circumference
- Important: up to 1 year of age, their chest circumference should be less than their head circumference
- If a newborn had the same head and chest circumference, this could mean their head is not growing (micromegaly)
Newborn (Birth-1 Month) Gross Motor Skills
may lift head if prone
*Infants should sleep on their backs to avoid SID, but they should be put on their belly with supervision to develop certain muscles
Newborn (Birth-1 Month) Fine Motor Skills
Holds hand in fist
Newborn (Birth-1 Month) Sensory
prefers faces, follows line of vision
- To check line of vision, do it with the mom, and have the mom hold the baby close to her and go back and forth to see if the baby follows the mom
When does the most rapid time of growth occur?
Before 6 months (especially at 2-4 months)
Fontanels and Sutures
Make sure fontanels and sutures are present in the newborn
- Posterior fontanel closes between 6-8 weeks
- Anterior fontanel closes around 18 months
- When palpating anterior fontanel, asses to make sure that it is there, because if there is pre-mature closure then there is nowhere for the brain to grow
- If it is compressed inwards (sunken fontanel) it is a sign of dehydration
- Pulsating (as long as it is flat) is normal
- Full bulging fontanel could be ICP or over-hydration
Rooting Reflex
Brush the infant’s cheek and the infant should turn towards the finger
- This reflex is normally used for feeding
- Usually disappears around 3-4 months but can be present until up to 12 months
Palmar Grasp Reflex
Put finger in the baby’s hand and the baby should grasp on to it
- Starts to disappear around 3 months of age
Plantar Grasp Reflex
Put thumb up the middle of the foot and you want to see that they take their toes and try to put it around the thumb
- Starts to disappear around 8 months of age
Babinski Reflex
- Want to see this reflex in children up to 18 months of age
- The toes flare as your draw an upside down C with thumb on bottom of the foot
Moro Reflex
- Pick up child and drop it down and the child should put arms up and out
- Can also just push down on the mattress
- Disappears around 4 months of age
- Will usually cry after testing this reflex
Tonic Neck Reflex
“Fencing reflex”
- Initiate it by turning the infant’s head to the side and then they will do this reflex
- This gets them prepared for gross motor skill of turning on to their belly
- Disappears no later than 6 months of age
Dance Reflex
Put on foot on a hard surface and the other foot should come up and vice versa
- Disappears around 4-8 weeks of age
Crawl Reflex
Disappears around 6 weeks
Newborn placed on abdomen and baby flexes legs under him and starts to crawl
Infant (birth to 1 month) bottle nutrition
60 to 90 cc every 2-3 hours
- There are 30cc in 1oz, so a glass of juice would be 240cc
Infant (birth to 1 month) breast feeding nutrition
every 2-3 hours on demand
-Want baby to have about 6-8 wet diapers a day, which is an indication that the baby is hydrated and breastfeeding adequately
2-4 Months Infant Growth
Same as newborn and posterior fontanels close
2-4 Months Infant Gross Motor Skills
Decrease head lag, sitting
- When you try and sit a baby up, their head goes backwards, but this is in a newborn and there is a decrease in this around 2-4 months of age
- Baby won’t be able to sit unsupported, but they may sit leaning on their hands
2-4 Months Infant Fine Motor Skills
holds rattle, loves to look and play with fingers, likes to bring object to mouth
- Give baby time to play with fingers to assess their fine motor if the baby has a developmental delay in some way
2-4 Months Infant Sensory
Turns head to voices
2-4 Months Infant Nutrition
feedings increasing to 90-120cc every 3-4 hours
- Decreased frequency of breast feeding, so also may occur 3-4 hours
2-4 Months Infant Language
“coo,” giggle, or laugh
*If baby isn’t making sounds, it could be an indication of a hearing deficit/loss
4-6 Months Infant Growth
At 6 months, birth weight doubles
4-6 Months Infant Gross Motor Skills
No head lag, rolling over, crawling
- In terms of rolling, baby will roll from BELLY TO BACK FIRST, around 4 months of age
- From back to abdomen occurs around 6 months of age
- Baby will also begin to crawl, which is when they move backwards
4-6 Months Infant Fine Motor Skills
Palmer grasp, manipulates objects
- At this time, baby should be reaching for objects; if you hold an object out, they should reach for it (whether they grab it is not important) and if they are not reaching for it then they may need a follow up
- When they have objects in their hands, they like to manipulate the object
4-6 Months Infant Nutrition
Baby food, weaning
- Babies are starting to eat solids around 6 months of age, usually will be rice cereals
- Rice cereals= easiest to digest and less chance of developing an allergic reaction
- Should wait between 4-7 days before introducing foods
- *This will allow you to tell what causes an allergic reaction if one occurs
- Starts to decrease calories from bottle or breast milk because they are getting more nutrition from solid foods
- Teeth begin erupting by 6 months (lower incisors first)
- From time the baby is born you start oral hygiene; may be taking gauze or wash clothes and clean the gums
- Babies should not get bottle feedings before bed
- *May lead to milk bottle carries
- Never give juice in a bottle
- Never mix foods in a bottle
- Give foods alone to learn new tastes and textures
- Cereal first – rice – barely – oatmeal
4-6 Months Infant Sensory
Separation Anxiety
– Separation anxiety from when the baby is separated from their mom; they will begin to cry which is normal
- At this age, babies love to smile at themselves in a mirror and mirrors are great toys for them
6-8 Months Growth
Decreasing rate
6-8 Months Gross Motor
SITTING
- Can sit totally unsupported/without hands
- May start getting up on hands and knees to get ready for creeping
6-8 Months Fine Motor
Transfers objects, pincer grasps, bangs objects
- Starting to develop a pincer grasp; will be a crude pincer grasp at this stage
- Need to be careful that baby doesn’t put things in their mouth and choke since they are now able to start grasping things (choking is a big concern at this age)
6-8 Months Sensory
Stranger anxiety, responds to names
- Have separation and stranger anxiety
- Stranger anxiety: not liking to interact with strangers even if the mother is holding the baby
- If mother leaves then it’s best for her to leave something that smells like the mother/familiar person (needs transitional object) so the baby knows she is coming back
6-8 Months Nutrition
fruits and vegetables, juice from cup
*Best juice to have is apple juice, but it’s so high in sugar that it should be cut with water
6-8 Months Language
“Da-Da”
