19
Q

What is asthma?

A

Increased reactivity of the trachea and bronchi to various stimuli (allergens, exercise, cold)

Manifests by widespread narrowing of the airways due to inflammation, smooth muscles constriction, and increased secretions.

  1. Wheezing cough
  2. Increased secretions
  3. Dyspnea
  4. Increased accessory muscle use
  5. Anxiety

  7. Hypoxemia and hypocapnia
  8. Cyanosis
21
Q

What is cystic fibrosis?

A

A genetically inherited disease characterized by thickening of secretions of all exocrine glands, leading to obstruction (i.e. pulmonic, pancreatic, GI)

22
Q

List 3 clinical signs of cystic fibrosis.

A
  1. Menconium ileus
  2. Frequent respiratory infections
  3. Inability to gain weight despite adequate caloric intake
23
Q

What testing is needed to confirm a diagnosis of cystic fibrosis?

A

Postnatally by a blood test indicated trypsinogen

OR

Positive sweat electrolyte test

24
Q

List 6 physical findings associated with cystic fibrosis.

A

25
Q

What is bronchiectasis?

A

A chronic congenital or acquired disease characterized by abnormal dilation of bronchi and excessive sputum production.

26
Q

What is respiratory distress syndrome?

A

Respiratory distress due to atelectasis caused by insufficient surfactant in premature lungs

A

Blood and edema within the alveoli and interstitial space due to blunt chest trauma with or without rib fractures

A
  1. Cough with pink, frothy secretions
  2. Crackles
  3. Tachypnea
  4. Dyspnea

Q

List 5 physical findings associated with pleural effusion.

A

40
Q

What is atelectasis?

A

Collapsed or airless alveolar unit, caused by hypoventilation secondary to pain during the ventilatory cycle, bronchial obstruction/compression, low tidal volumes, or neurologic insult
