PREVIEW OF
LIFESPAN DEVELOPMENTPOWERPOINT TRAINING
PRESENTATION
INFANCY
Birth to 1 year
HEART RATE
Normal heart rate in newborns is between 140 and 160
Settling around 120 beats per minute
RESPIRATORY RATE
Initially 40-60Dropping to 30-40 after first few minutes of lifeSlowing to 20-30 by one yearTidal volume
6-8 ml/kg initiallyIncreasing to 10-15 ml/kg by 1 year
BLOOD PRESSURE
Average systolic blood pressure increases from70 at birth to 90 at 1 year
TEMPERATURE RANGE
98 to 100 degrees Fahrenheit is thethermoneutral range
WEIGHT
Normally 3.0-3.5 kg 9 (7-8 pounds)at birthNormally drops 5 to 10 percent in the first week
of lifeInfants head equal to 25 percent of the total
body weight
PULMONARY SYSTEM
Airways, shorter, narrower, less stable, more easily obstructed
Infants primarily nose breathers until four weeksLung tissue is fragile and prone to trauma from
pressureFewer alveoli with decreased collateral ventilation
PULMONARY SYSTEM
Accessory muscles immature, susceptible to early fatigue
Chest wall less rigidDiaphragmatic breathingRapid respiratory rates lead to rapid heat, and
fluid loss
IMMUNE SYSTEM
Passive immunity retained through the first six months of life
Based on maternal antibodies
NERVOUS SYSTEM
Strong, coordinated suck and gagWell flexed extremitiesExtremities move equally when infant is stimulatedReflexes
FONTANELLES
Posterior fontanelle closes at three months
Anterior fontanelle closes between 9 and 18 months
Fontanelles may provide an indirect estimate of hydration
GROWTH & DEVELOPMENTOVER THE FIRST YEAR
Two monthsTracks objects with eyesRecognizes familiar faces
Six monthsSits upright in a highchairMakes one syllable sounds (e.g., ma, mu, da, di)
12 monthsWalks with helpKnows own name
PSYCHOSOCIAL DEVELOPMENT
CryingBasic cryAnger cryPain cry
Situational crisis – parental separation reactionsProtestDespairWithdrawal
TODDLER & PRE-SCHOOL
Toddler 12-36 months oldPre-School 3-5 years old
SCHOOL AGE CHILDREN
6-12 years old
VITAL SIGNS
Normal heart rate is between 70 and 110 beats per minute
Normal respiratory rate is between 20 and 30 breaths per minute
Normal systolic blood pressure is between 80 and 120 mmHg
Normal temperature is 98.6 degrees Fahrenheit
ADOLESCENCE
13-18 years old
DEVELOPING IDENTITY
Peer pressure increasesInterest in the opposite sex increasesWant to be treated like adultsAnti-social behavior peaks around eighth or ninth gradeBody image of great concern
Continual comparison amongst peersEating disorders are common
EARLY ADULTHOOD
20-40 years old
VITAL SIGNS
Heart rate—average 70 beats per minuteRespiratory rate—average 16 to 20 breaths per
minutesBlood pressure—average 120/80 mmHgTemperature—98.6 degrees Fahrenheit
LATE ADULTHOOD
61 years & older
VITAL SIGNS
Heart rate—depends on patient’s physical and health status
Respiratory rate—depends on patient’s physical and health status
Blood pressure—depends on patient’s physical and health status
Temperature—98.6 degrees Fahrenheit
RENAL SYSTEM
50 percent of nephrons (kidney structure) lostAbnormal glomeruli (blood capillaries in the
kidneys) more commonDecreased elimination
