Chapter 7 Life Span Development EMT
Early adults
19-40 years old. Focus on work and family.
Middle adults
41-60 years old. Focus on achieving life goals.
School age
6-12 years
Older Adults
61 years and older. Focus on their mortality and the mortality of friends and loved ones.
5 months
Sleeps throughout the night; recognizes family members from strangers
Moro reflex
(startle reflex) happens when a neonate is caught off guard by something or someone; the neonate opens his or her arms wide, spreads the fingers, and seems to grab at things.
Older people: Nervous System
- NS changes can result in the most debilitating of age-related illness. - The metabolic rate in the older brain does not change, however, and oxygen consumption remains constant throughout life. - Biphasic (two phased) sleep cycle - Age related shrinkage of the brain results in space between the brain and its cover, the dura mater. Bleeding in this area can occur because the veins are stretched.
Older people: Renal System
- The number of nephrons declines between the ages of 30 and 80 years; meaning a decrease in the ability to clear waste and conserve fluids when needed. -Kidney size decreases by 20%, and filtration function decreases by 50%: due to the decreased effectiveness of the blood vessels that supply blood to the nephrons
Older people: The Cardiovascular System
-Atherosclerosis: Commonly affects coronary vessels, cholesterol and calcium build up inside the walls of the vessels, forming plaque. More than 60% of people older than 65 have this disease. -decrease in heart rate -decrease in cardiac output -inability to elevate cardiac output to match the demands of the body; the heart is then less able to respond to exercise or disease. - In life threatening injuries the body typically needs to increase , this can actually cause damage to the older heart
Older people: Digestive System
-Changes may inhibit nutritional intake and utilization -Saliva secretion decreases; reduces body's ability to process complex carbohydrates -Blood flow may drop as much as 50%
Older people: The respiratory system
-Size of the airway increases and surface area of the alveoli decreases -Rigid chest= calcified chest can fracture - Innervation of the structures in the airway provides less sensation; resulting in more difficulty to maintaining the upper airway= greater risk of airway obstruction -Strong inhalation can cause walls of the airway to collapse= inspiratory wheezing -White blood cells found in the airway are less aggressive, increasing the risk of lung infections
infant
A child age 1 month to 1 year.
Neonate
A newborn age birth to 1 month
7 Months
Afraid of strangers; mood swings
toddler
Ages 1-3 years
Preschooler
Ages 3-6 years
3 Months
Brings objects to the mouth; smiles and frowns
Fontanelles
Areas where the neonates or infants skull has not fused together; usually disappears at approximately 18 months of age - The posterior fontanelle normally fuses by the third month of life. - The anterior fontanelle fuses between 9 and 18 months of age. On assessment, if either of the fontanelles is depressed, the infant is most likely dehydrated. A bulging fontanelle is indicative of increased intracranial pressure.
Nephrons
Basic filtering units in the kidneys
Preconventional reasoning
Children act almost purely to avoid punishment and to get what they want.
Conventional reasoning
Children look for approval from their peers and society.
Postconventional reasoing
Children make decisions guided by their conscience.
The leading cause of death for neonates?
Congenital abnormalities
Pulse Rate: 70 beats/min RR: 12-20 breaths/min SBP: 90-140 mm Hg
Early Adults Middle adults
12 Months
Knows his or her name; walks
9 Months
Pulls up to stand; places objects in mouth to explore them.
4 months
Reaches out to people; drools
2 Months
Recognizes familiar faces, tracks objects with the eyes.
10 Months
Responds to his or her name; crawls efficiently.
11 Months
Starts to walk without help; frustrated with restrictions
Rooting reflex
Takes place when something touches a neonate's cheek; the neonate will instinctively turn his or her head toward the touch.
6 Months
Teething begins; sits upright; speaks one-syllable words
Older people: The Endocrine system
When a person gains weight more insulin is needed to control the body's metabolism and blood glucose (sugar) level.
Separation anxiety
is common in older infants. Peaks between 10 and 18 months and involves clingy behavior and fear of unfamiliar places and people
Self-esteem
is how we feel about ourselves and how we fit in with our peers.
Anxious-avoidant attachment
is observed in infants who are repeatedly rejected. -These children show little emotional response. -These children often develop an isolated lifestyle where they do not have to depend on the support and care of others.
Self-concept
is our perception of ourselves.
Sucking reflex
occurs when a neonate's lips are stroked.
Secure attachment
occurs when an infant understands that parents or caregivers will respond to their needs.
Palmar grasp
occurs when an object is placed into the neonate's palm.
Trust and mistrust
refers to a stage of development from birth to about 18 months of age that involves an infant's needs being met by his or her parents or caregivers.
8 months
responds to "no", can sit alone; plays peek a boo
Bonding
the formation of a close, personal relationship, is based on a secure attachment.
