sleep problems in preschoolers - CORRECT ANSWER- •nightmares,
night terrors, difficulty settling down after a busy day, extending bedtime
rituals to delay sleep
preschoolers safety concerns - CORRECT ANSWER- •Less prone to
accidents, but at risk for the same type of injuries and require many of
the same type of safety precautions as toddlers
preschooler fears - CORRECT ANSWER- •Imaginary monsters
•
•Strangers and "strange" people
•
•Animals they are not familiar with
•
•Loud noises
•
•The dark
•
•Pain (can remember painful experiences)
•
•Bodily mutilation
preschooler approach to assessment and care - CORRECT ANSWER-
•Demonstrate on doll or teddy bear
•Simple explanations, DO NOT LIE
,•Allow to handle equipment
•Be mindful of your word choices as they are very literal
-Dye means die
•Teach about procedures a few hours before
school age children physical growth - CORRECT ANSWER- •Girls
grow faster than boys and may surpass them in height and weight
•
•10-13 yrs (preadolescence) - rapid and uneven growth
•
•Grows 2 inches/year
•
•Gains 4 to 7 lbs per year
Functions of the musculoskeletal system - CORRECT ANSWER-
•Protection of vital organs
•Mobility and movement
•Facilitate return of blood to the heart
•Production of blood cells (hematopoiesis)
•Reservoir for immature blood cells
•Reservoir for vital minerals
Coordinated efforts of the musculoskeletal and nervous systems -
CORRECT ANSWER- body mechanics
force that occurs in a direction to oppose movement - CORRECT
ANSWER- friction
regulating factors of bone formation and maintenance - CORRECT
ANSWER- -Stress and weight bearing
-Vitamin D
-Parathyroid hormone and calcitonin
-Blood supply
normal calcium level - CORRECT ANSWER- 9-10.5 mg/dL
developmental changes in infants, toddlers, and preschoolers -
CORRECT ANSWER- •Prolonged immobility delays gross motor skills,
intellectual development, or musculoskeletal development
,very bow-legged and top heavy - unsteady gait so increased risk for
injury
developmental changes in adolescents - CORRECT ANSWER-
•Delayed in gaining independence and in accomplishing skills
•Social isolation can occur if there is trauma, illness, surgery, etc
"risk-takers"
developmental changes in adults - CORRECT ANSWER-
•Physiological systems are at risk
•Changes in family and social structures
^^ with prolonged immobility because they tend to have sedentary
lifestyles
developmental changes in older adults - CORRECT ANSWER-
•Decreased physical activity
•Hormonal changes
Bone reabsorption
more comorbidities; bones more brittle and weak
spinal changes (kyphosis), side to side gait ... encourage them to look up
ability to move about freely - CORRECT ANSWER- mobility
inability to move about freely - CORRECT ANSWER- immobility
an intervention that restricts patients for therapeutic reasons -
CORRECT ANSWER- bed rest
metabolic effects due to impaired mobility - CORRECT ANSWER-
endocrine, calcium absorption, and GI function
kidneys unable to secrete calcium = hypercalcemia = fractures possible
, CV effects due to impaired mobility - CORRECT ANSWER-
orthostatic hypotension, thrombus
also dizziness, n/v, tachycardia, pallor, fainting
muscle effects due to impaired mobility - CORRECT ANSWER- loss
of muscle mass, atrophy
urinary elimination effects due to impaired mobility - CORRECT
ANSWER- urinary stasis
renal calculi (bc hypercalcemia_
respiratory effects due to impaired mobility - CORRECT ANSWER-
atelectasis (collapse of alveoli) and hypostatic pneumonia (inflammation
of lungs from stasis of secretions)
musculoskeletal effects due to impaired mobility - CORRECT
ANSWER- loss of endurance and muscle mass and decreased stability
and balance
skeletal effects due to impaired mobility - CORRECT ANSWER-
impaired calcium absorption, joint abnormalities
ex: disuse osteoporosis = pathological fx possible
integumentary effects due to impaired mobility - CORRECT ANSWER-
pressure ulcer, ischemia
describe the change of metabolic changes due to immobility -
CORRECT ANSWER- immobility --> muscle atrophy --> negative
nitrogen balance --> further loss of mass --> increased weakness
** nutritional intake due to anorexia and/or restrictions can affect
negative nitrogen balance and increase weakness even more **
what kind of muscle/skeletal effects can immobility cause? -
CORRECT ANSWER- dorsal and plantar flexion
