Acid-base: Respiratory Acidosis Flashcards

1
Q

Describe what is happening to the body with respiratory acidosis

A

The body is not able to get rid of enough CO2 for some reason, resulting in CO2 retention which causes the body to become acidic.

Q

What are the clinical manifestations of acute respiratory acidosis?

A
  1. PaCO2 levels rise rapidly

Q

What happens to the bicarbonate levels in acute and chronic respiratory acidosis?

A

Acute: initially normal

Chronic: may be significantly elevated trying to compensate for the amount of acidity in the body

Q

What diagnostic tests are typically ordered for Respiratory acidosis?

A
  1. Serum electrolytes: for chloride and calcium levels
  2. Pulmonary function tests: Determine whether the chronic lung disease is the underlying cause
  3. Chest x-ray
  4. sputum studies
  5. serum levels of suspected drugs

Q

What respiratory support is typically given for respiratory acidosis?

A
  1. focus on improving alveolar ventilation and gas exchange
  2. Severe acidosis and hypoxemia: intubation and mechanical ventilation
  3. PaCO2 level lowered slowly
  4. O2 administered cautiously
  5. Pulmonary hygiene
  6. Adequate hydration

Q

What are some interventions to promote gas exchange?

A
  1. promptly evaluate and report ABG results
  2. Place in semi-Fowler or Fowler position as tolerated
  3. Administer O2 as ordered
  4. Monitor response to O2
  5. Immediately report increasing somnolence
17
Q

What are some interventions to promote effective airway clearance?

A
  1. frequently auscultate breath sounds
  2. Encourage pursed-lip breathing
    3 Frequently reposition and encourage ambulation
  3. Encourage fluid intake
  4. Administer medications
  5. Provide percussion, vibration, postural drainage as ordered
18
Q

What are some interventions to reduce anxiety levels?

A
  1. result of hypoxia and hypercapnia
  2. remain with patient and monitor
  3. Explain procedures and treatments
  4. Reduce environmental stimuli
  5. use calm, reassuring manners
  6. Allow supportive family members to remain with patient as much as possible
19
Q

What are some interventions to reduce the risk for injury?

A
  1. Be aware that patients may experience blurred vision and altered LOC
  2. Assess LOC, mental status, orientation frequently
  3. Place call alarm controls within reach
  4. Manage rest, activity patterns
  5. Administer supplemental O2 as needed
20
Q

What are some things to tell the patent to prepare them for discharge?

A
  1. teach the patient and family about preventive measures and equipment
  2. refer the patient to substance abuse treatment if needed
  3. Encourage the patient to receive immunizations
  4. Provide instructions when the respiratory status is compromised
  5. Alert to early symptoms that warrant immediate attention
