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 • • Hepatitis B DTa. P Hib Polio (IPV) MMR Varicella PCV 13
