Q

What things should you look for while assessing an infant’s gas exchange ability?

A
  1. check for pectus carinatum (pigeion chest) or pectus excavatum (caved in)
  2. during palpation, not facial expression, presence of crying
  3. palpate the area near the clavicle for crepitus
  4. assess infants for tactile fremitus
  5. avoid auscultating through clothing, as breath sounds may be small
28
Q

What should you look for when assessing a toddlers and elementary age kids for gas exchange?

A
  1. inspect for pectus carinatum, pectus excavatum, kyphosis, scoliosis
  2. should not be barrel chest over the age of 6
  3. should be no retractions
  4. have the child repeat words or numbers to assess for tactile fremitus
  5. ask the child to breathe deeply during auscultation
29
Q

What are some physiological differences in pregnant women?

A
  1. pregnancy raises the diaphragm which decreases the ability to expand the lungs
  2. chest circumference increases
  3. changes to upper respiratory mucosa increase the likelihood of developing nasal stuffiness, nosebleeds
  4. residual capacity decreases
30
Q

What position should you avoid putting a pregnant women in?

A

prolonged supine positioning

31
Q

What are the physiologic changes in older adults that affect gas exchange?

A
  1. increased risk of developing respiratory infections

  4. increased incidence of Gastroesophageal reflux= increased risk of aspiration of food
32
Q

What should you look for when assessing an older adult for gas exchange complications?

A
  1. breath sounds= decreased w/ crackles
  2. kyphosis/scoliosis
  3. COPD
  4. Changes in meds
  5. Changes in fluid and nutrition status
  6. changes in LOC
33
Q

What are some treatments that put people at risk for Gas Exchange complications?

A
  1. frequent suctioning (decreased gag reflex, the cough reflex/ use lower suction pressure)
  2. Pt teaching on enhancing coughing to help clear secretions
  3. incentive spirometry
  4. assess adherence to the treatment regimen, barriers to adherence
34
Q

What are some signs of hypoxia?

A
  1. Increased restlessness, irritability, and unexplained sudden confusion
  2. Rapid HR + rapid RR
35
Q

What hx should you look for when assessing gas exchange?

A
  1. Curie the respiratory probs
  2. Hx of respiratory disease
  3. Lifestyle
  4. Presence of cough
  5. Description of sputum
  6. Presence of chest pain
  7. Risk factors
  8. Meds
36
Q

What are some major signs of impaired gas exchange?

A

Clubbed finger nails, agitation, low RR, kidney output would be decreased

37
Q

What are some diagnostic tests used to evaluate impaired gas exchange?

A
  1. Sputum specimen

  5. Chest x-ray
  6. Pulmonary angiogram
  7. Pulmonary V-Q scans
  8. Bronchoscopy
38
Q

Whyat are some interventions for impaired gas exchange?

A

Q

If a pt has a new onset of confusion, what should you check first?

40
Q

If an elderly pt falls today how long could it take before you start to see symptoms of confusion?

A

1-2 months

41
Q

What are some meds used for impaired gas exchange?
