CHAPTER 19
Child Health
Child Health Overview
• Well-child visit
– Health professionals assess child for:
• Current health status
• Progression of growth and development
• Need for immunizations
– Health professionals have opportunity to
teach parents about child’s growth and
development
2
Growth and Development
• Growth
– Physical increase in whole or any of its part
– Parameters of a child’s growth can be
easily measured with accuracy through the
following:
•
•
•
•
Weight
Head circumference
Length or height
Dentition
3
Growth and Development
• Weight
– Important indicator of child’s nutritional
status and general growth
– Used to calculate medication dosages for
children
– Should be measured at every visit
4
Growth and Development
• Head circumference
– Related to intracranial volume
– Normal brain growth = expected rate of
increase in head circumference
– Abnormal lags or surges may indicate
serious problems
5
Growth and Development
• Length or height
– Compared with head circumference and
weight measurement for overall indicator of
physical growth
– Measure infant from crown of head to heel
• Place child in recumbent position
– Standing height measurement for children
three years or older
6
Growth and Development
• Dentition
– Refers to eruption of teeth and follows
sequential pattern
– Eruption of primary teeth – 6-30 months
• Twenty primary teeth
– Eruption of permanent teeth - around 6
years of age
• Normally 32 permanent teeth
7
Growth and Development
• Development
– Increase in function and complexity that
results through learning, maturation, and
growth
– Development screening tests used as
assessment tools
• Brazelton Neonatal Behavior Assessment Scale
for Newborns
• Dubowitz for newborns
• Ages and Stages Questionnaires (ASQ)
8
Growth and Development
• Stages of childhood growth and
development
– Newborn – birth to one month
– Infancy – One month to one year
– Toddlerhood – One to three years
– Preschool Age – Three to six years
– School Age – Six to twelve years
– Adolescents – Twelve to eighteen or twentyone years
9
Growth and
Development Principles
• Cephalocaudal
– Growth and development proceeds from
head to toe
• Muscular control follows the spine downward
• Proximodistal
– Growth and development proceeds from
center outward or from midline to periphery
10
Growth and
Development Principles
• General to specific
– Activities move from being generalized
toward being more focused
• Simple to complex
– Language develops from simple to complex
• Growth spurts
– Occur throughout childhood
• Alternate with periods of slow growth
11
Immunizations
• Immunization
– Process of creating immunity to a specific
disease in an individual
– Medication administered is a vaccine
• Suspension of infectious agents or some part of
them
• Given to establish resistance to an infectious
disease
• Immunity
– State of being immune to or protected from a
disease, especially an infectious disease
12
Immunizations
• Childhood immunizations
– Administered to well child according to specific
schedule
– Recommended childhood immunizations
•
