Solitary play
Does not share with others or directly play with others
26
Breast milk includes
LActose, lipids, polyunsaturated fatty acids, amino acids Contribute to myelination of nervous system

# DEVELOPMENTAL THEORIES FOR NEWBORN AND INFANT What is Erikson developmental theory

48
# DEVELOPMENTAL THEORIES FOR NEWBORN AND INFANT Piaget theory Sensorimotor - Substage 1 Substage 2 Substage 3 Substage 4
**Sensorimotor** - Uses senses and skills to learn about world **Substage 1 **- Reflexive sucking bring nutrition, begin to gain control over reflexes and recognize objects, odors, sounds **Substage 2** - Thumn sucking, Imitiation begins, Object permanance begins, infant shows affect **Substage 3 **- Repeats actions to get results **Substage 4** - Coordinate previously learned schemes wtih learned behaviors. Shake rattle, crawl. Anticpiate events, assoc symbols with events (waving goodbye when leaving)

above elbows or knee Do not start an IV on same extremeity as central line *Attempt your iV at most distal part and work up
120
# DIVERSE SETTINGS NUTRITIONAL SUPPORT ENTERAL OG/NG/NJ/ND/GT/JT
**For children who can tolerate feeding but cannot eat normally (coma, oral aversion,s evere reflux)** OG - Orogastric / mouth to stomach NG - Nasogastric / nasal to stomach NJ - Nasojejunal / nasal to jejunum ND - Nasoduodenal / nasal to duodenal Gt - Gastrostomy / surgical opening JT - Jejunostomy / surgical opening
121
# DIVERSE SETTINGS NUTRITIONAL SUPPORT PARENTERAL
Nutrition given through IV or TPN through central line For chidlren who cannot tolerate food through GI tract (Nonfunctioning GI, postop, NEC, short gut)
122
# DIVERSE SETTINGS **Nursing care of a child with enteral tube** Confirming placement Signs of misplacement
Placement confirmed -Check color/pH of aspirate *-pH 5 or less = OK to feed, 5 or greater hold feeding and notify* -Check external marking of tube and verify length **-Always HOB up 30 degrees when feeding** **Signs of misplacement** -Unexplained gagging, vomitting, coughing, signs of respiratory distress
123
# DIVERSE SETTINGS Bolus feed Continuous feeds
**Bolus** - over 30 min q 3- hours. allows child to be up and not tied down **Continuous** - Continuous over a feeding pump / tied to pump can interfere with developmental
124
# DIVERSE SETTINGS Complications with TPN
-Infused through central line which requires heparin for patency. TPN contains heparin and dextrose = can cause hyper/hypoglycemia = **check blood lgucose levels** -Cannot change rate w/o order -Strict aseptic techniques -Closed system. Do not leave ports/caps open. Can cause infection (CLABSI) -Closely monitor I&O
125
# DIVERSE SETTINGS TPN - Daily fluid requirements
1st kg = 1000ml 2nd kg = 500ml remaining kg = 20ml/kg
126
# PAIN MGMT in CHILDREN When a childs pain is not managed what physical and emotional consequences can develop?
**Physical** - can delay healing/ can lead to increased oxyegen needs and alter blood glucose **Emotional** - fear, anxiety and increased healing time
127
# PAIN MGMT in CHILDREN Transduction
**Process of nociceptor activation** -Nerve fibers extend from spinal cord to peripheral. At end of these fibers are nociceptors. -Nociceptors become activated when exposed to harmful stimuli (chemical, mechanical, theramal)
128
# PAIN MGMT in CHILDREN Transmission - define -Large myelinated A-delta fibers -Small unmyelinated C-fibers
**Neurotransmitters pass pain to the brain through electrical impulses** **Large myelinated A-delta fibers** - transmit pain quickly causing reflex response to withdrawl from stimulus (mostly mechanical or thermal) **Small unmyelinated C-fibers** - transmit pain slowly (chemical)
129
# PAIN MGMT in CHILDREN Perception
Thalamus quickly sends pain signals to: **cerebral cortex **(interpreted as sharp, dull, stabbing, burning) **limbic system** (interpreted emotionally and memory occurs) **Brain stem** (autonomic nervous system - BP,HR,RR, digestion)
130
# PAIN MGMT in CHILDREN Modulation - define Naturally occuring example??
Process by which body alters pain signal as it is transmitted along pain pathway (why individual response to pain is different) Analgesics and anesthetics interrupt pain perception Serotonin, endorphines, enkephalins, dynorphins
131
# PAIN MGMT in CHILDREN A-delta fibers lead to pain feeling like C fibers lead to pain feeling like
A-delta - sharp, stabbing, local pain Cfibers - dull, diffuse, burning, aching
132
# PAIN MGMT in CHILDREN Classifications of pain Duration Etiology Source/location
**Duration** - Acute- Rapid onset, resolves with healing, protective function Chronic - Continues past point of healing, no protective function **Etiology** - Nociceptive - damage to body tissues, usually external Neuropathic - nerve pain **Source/location - ** Somatic - superficial or deep that develops in tissues Visceral - develops in organs by disease / poorly localized may be referred
133
# PAIN MGMT in CHILDREN Pain assessment using QUEST
**Question** the child **Use** a reliable and vali dpain scale **Evaluate** behavior/physiologic changes to esta baseline and determine effectivness **Secure** patients involvment **Take** cause of pain into account **Take** action
134
# PAIN MGMT in CHILDREN Reaction to pain Toddler preschool School age Adolescent
**Toddler** - may react to painless procedures as they do to painful ones **preschool** - think pain is punishment **School age** - appear brave to avoid more pain or embarassment **Adolescent**- moody, fear of losing control
135
# PAIN MGMT in CHILDREN -What are nonpharmacological pain mgmt - behavioral -cognitive stratgies
Thought stopping Imagary Humor Relaxation Distraction
136
# PAIN MGMT in CHILDREN -What are nonpharmacological pain mgmt - biophysical stratgie
non-nutritive sucking/sucros breastfeeding massage heat - increases blood flow, decrease nociceptor & swelling cold - vasoconstrict, decrease edema, histamines and transmission of painful stimuli
137
# PAIN MGMT in CHILDREN nonopioid analgesics opioid analgesics
-acetaminophen and NSAIDS (do not use ASPIRIN for REYES SYNDROME) -Morphine, fetanyl, dilaudid
138
# PAIN MGMT in CHILDREN Adjuvant Anesthetics
**Adjuvant**: benzo's, anticonvulsant, antidepressant **Anesthetics**: Local, EMLA cream (painful procedure), TAC (lacerations required suturing), vapocoolant spray
139
Incubation
Time from entrance of pathogen to first symptom
140
Prodrome
Time from appearance of nonspecific symptoms (fatique, malase) to more specific symptoms
141
Illness
Signs and symptoms of disease are clearly evident
142
Convalescence
Acute symptoms begin to disappear
143
What is the chain of infection Infectious agent - Reservoir - Portal of exit - Mode of transmission - Portal of entry - Susceptible host -
**Infectious agent **- agent capable of causing infection **Reservoir **- place where pathogen can grow **Portal of exit** - mucous membranes, skin resp tract, Gi, GU) **Mode of transmission** - way it travels **Portal of entry **- mucous membranes, skin resp tract, Gi, GU) **Susceptible host **- any person who cannot fight
