NUR 2214 Exam 2|114 Questions andAnswers |A+ Graded
What is normal body temperature (C) - -35.5-40 C
-What is the control center for thermoregulation - -Hypothalamus
-receives input from receptors throughout body
-Which part of the hypothalamus controls vasodilation and sweating? - -
Anterior Hypothalamus Stimulation
-Which part of the hypothalamus controls shivering - -Posterior
Hypothalamus Stimulation
-Who is at a higher risk for developing life-threatening disturbances of
temperature regulation due to normal age-related changes - -Elderly People
-How much longer does it take for an elderly person to return to normal core
body temperature? - -2x
-At what age does diminished ability to thermoregulate occur? - -About age
70 and worsens with each decade of life
-What can put elderly people at risk for heat loss - -Decreased sub Q fat
-What is hypothermia - -Core body temp below 35 C
-What are some early signs of hypothermia: - -Fatigue
Slow Gait
Apathy
Slurred Speech
Confusion
Shivering
Cool Skin
A cold sensation
Muscle weakness
-What are signs of hypothermia that the body temperature is continuing to
fall? - -Cold Skin
Cyanosis
Bradycardia
Atrial & Ventricular Arrhythmias
Hypotension
Stupor or Coma
, Muscle Rigidity (Middle/Late)
Generalized Edema
Slowed Reflexes
Poorly Reactive Pupils
Oliguria
-What are the very late signs of hypothermia - -Very Cold Skin
Muscle Rigidity (Middle/Late)
Apnea
Unresponsiveness
Fixed Pupils
-What is the most significant complication of severe hypothermia - -
Cardiorespiratory Arrest
-What puts Elderly People at risk for hypothermia - --May cut back on
heating during winter to save money
-Decreased heat production & Increased heat loss
-Less muscle mass & less alveolar surface in the lungs (Immobility &
decreased activity)
-Changes in sweat glands
-What is the skins primary function - -Provide protection from environment
(regulates temp, retains fluids, absorbs shock & UV radiation)
-What is the body's primary source of metabolic heat - -Muscle Mass
(Muscle contractions= Heat generation)
-When does general reduction in size, elasticity, & strength of all muscle
tissue occur? - -As early as 3rd decade of life
-What are major contributing factors to decreased lung function with age -
--Progressive loss of elastic recoil within lung tissue
-Chest wall becomes stiffer
-Decrease in alveolar surface area
-How does respiratory function effect thermoregulation with age? - -
Impaired respiratory function leads to decreased mobility & therefore,
decreased heat production
-What happens to the endocrine and metabolism with age? - -Generalized
reduction in hormone production & activity
-What are common disorders in the elderly? - --Water
-Mineral
-Electrolyte
