Q

the older adult >65

A
  • death in advanced years not caused by “old age” but disease or infection
  • greater risk for illness (normal decline in adaptation)
  • changes of aging become apparent when the body is under stress

homeostasis

A

body’s ability to adapt to or return to a normal state of balance after being subjected to a threat or stress (injury, exposure to pathogens, changes in fluid and nutritional intake, effects of medication, etc.)

Q

ingeumentary and older adults

A
  • decreased subq fat, interstitial fluid, muscle tone, glandular activity, and sensory receptors, resulting in atrophy and decreased protection against trauma, sun exposure, and temperature extremes,
  • diminished excretions of natural oils and perspiration
  • capillary fragility

Q

distribution changes in older adults

A

  • may occur if air or blood collects in pleural space and is not removed, the postive pressure in pleural caavity increases and the affected lung collapses
  • can result in compression of heart, vena cava, aorta, and contralateral affected lung
  • tracheal deviation toward unaffected side

Q

cardiac tamponade

A
  • excessive air, fluid, or blood collecting in pericardial sac
  • heart cannot adequately fill or contract because of compression of ventricles
  • treated with a pericardiocentesis the insertion of large bore needle into pericardial space to drain the fluid
321
Q

assessments of chest trauma

A
  • respiratory effort
  • visualization of chest
  • breath sounds
  • VS
  • pain
  • LOC
  • chest tube
  • subq emphysema
322
Q

chest tubes

A
  • assess amount and color of drainage
  • red free flowing drainage in excess of 100 mL/hr or amount indicated by provider indicates hemorrhage; cloudiness may indicate infeciton, notify HCP drainage amount
  • water seal chamber may tidal but shouldn’t show continuous bubbling or indicative of air leak
323
Q

subq emphysema

A
  • air from chest injury espacing into subq space indicating potential chest trauma or chest tube not positioned appropriately
  • subq emphysema of head and neck could be life threatening because airway could be compromised
324
Q

nursing interventions for chest trauma

A
  • o2
  • anticipate and prep for intubation
  • elevate HOB
  • encourage cough and deep breathing, incentive spirometer
  • encourage early ambulation
  • amdin pain meds
  • chest tube management
325
Q

education for chest trauma

A
  • use of pain meds
  • cough and deep breathing
  • incentive spirometer
  • splinting while coughing
  • MTV safety
