Chronic Bronchitis is definitely a disease that all Respiratory Therapy students should be familiar with. That is because, once you start practicing as a licensed Respiratory Therapist, you will need to have a good understanding of the disease in order to treat your patients effectively.
That is why we put together this study guide that is loaded with Chronic Bronchitis practice questions to help you learn all of the most important facts about the disease. So are you ready to get started?
Chronic Bronchitis Practice Questions:
1. What is the definition of chronic bronchitis?
It is a chronically productive cough due to bronchial inflammation. In this condition, the bronchial mucus glands are enlarged. It is termed “chronic” when it lasts for at least three consecutive months of the year for two or more successive years.
2. What is the classification of chronic bronchitis?
It is defined clinically rather than pathologically. It is termed chronic when it lasts for at least three consecutive months of the year for two or more successive years and is categorized as COPD (chronic obstructive pulmonary disease). Other potential causes of a chronic cough must be excluded.
3. What is the etiology of chronic bronchitis?
Cigarette smoking is the number one cause. Pipe and cigar are contributing but in less degree. Severe and repeated childhood respiratory infections may increase susceptibility in later life. The disease is rare with non-smokers.
4. What is a nickname that we give to chronic bronchitis patients?
5. What are the ABG results for chronic bronchitis?
Acute alveolar hyperventilation and hypoxemia.
6. Chronic bronchitis is a type of what?
Chronic bronchitis is a type of COPD and is an obstructive disease.
7. What is the pathophysiology of chronic bronchitis?
Increased mucus production, inflammation of small airways, loss of cilia and mucus plugging that causes airway obstruction that could lead to atelectasis.
8. What are the causes of pulmonary hypertension?
Hypoxemia leads to polycythemia. Acidosis adds to the contraction of the smooth muscles in the pulmonary blood vessels. It is the result of jugular vein distention and pedal edema. cor
9. What are the causes of cor pulmonale?
Right heart failure in later stages due to an increased workload on the right ventricle. It is caused by hypoxemia and constricts pulmonary vasculature leading to polycythemia with loss of mental acuity. Cor pulmonale is due to hypoxemia then it constricts pulmonary vasculature, a condition that affects the blood vessels along the route between the heart and lungs, which leads to polycythemia and eventually right heart failure.
10. What is the diagnosis of chronic bronchitis?
Patients often deny symptoms because onset has been gradual and has become accustomed to symptoms. They do not consider symptoms seriously until exacerbation occurs as a result of acute infection. It is important to note smoking history in pack years.
11. What are the symptoms of chronic bronchitis?
Increased cough, increased sputum production leading to mucoid (clear and thick), purulent (containing pus), hemoptysis (blood from rupture of superficial blood vessels), shortness of breath (dyspnea), mild at first but gradually increases over time, increases with exertion and eventually shortness of breath persists at rest.
12. What are the signs of chronic bronchitis?
Accessory muscle use, breath sounds are prolonged expiratory phase with wheezing, rales and may clear with a cough.
13. What is the cause of cyanosis (more common than in emphysema) in chronic bronchitis?
Hypoxemia and polycythemia.
14. What are the characteristics of a blue bloater?
Stocky, overweight has a chronic productive cough, mildly distressed, cyanotic, swollen ankles and legs (pitting edema) distended neck veins as a result of cor pulmonale (right-sided heart failure), episodes of right side heart failure (blood vessels divert blood for less damage of the lung and oxygen is more available constricted vessels cause high blood pressure in the lungs), pulmonary hypertension, bluish color of the lips and skin, severe airway disease with less emphysema, relatively mild dyspnea, no weight loss, large heart, polycythemia, hypercapnia and hypoxemia (low oxygen in the blood).
15. What can be seen in radiographic findings?
Hyperlucency (darkening, due to air trapping), flattened diaphragms,
16. What can be observed on the pulmonary function test of patients with chronic bronchitis?
17. What are the laboratory findings of patients with chronic bronchitis?
RBC increase in advanced disease and polycythemia. HCT and HB are increased in advanced disease and polycythemia. WBC is increased if infection present. ABG results will show
18. What are the available treatments for chronic bronchitis?
Smoking cessation that may limit
19. What comprises bronchopulmonary hygiene therapy?
Chest physiotherapy, clearance devices, flutter valve, acapella and aerobics.
20. What is needed in aerosolized medication?
21. What are the six ways to manage chronic bronchitis?
Decrease/stop smoking, bronchodilator therapy, reduce exposure to irritants, adequate rest, proper hydration and physical reconditioning.
22. What is the prognosis of chronic bronchitis?
It is variable. The patient may have a chronic productive cough for years without impairment of lung function and may progress quickly to disability. Some patients may have frequent infections with exacerbations and may progress to emphysema.
23. What are the chest findings of patients with chronic bronchitis?
Decreased tactile and vocal fremitus, hyper-resonant percussion note, diminished breath sounds, crackles/rhonchi/wheezes and use of accessory muscles.
24. What are the x-ray findings of patients with chronic bronchitis?
No abnormalities except the large bronchi. As peripheral bronchi are involved, significant ga trapping may occur. There is an enlarged heart if cor pulmonale is present and increased residual capacity. The diaphragm may be depressed or flattened,
25. What are the major pathological changes associated with chronic bronchitis?
Chronic inflammation and swelling of the wall of the peripheral airways, excessive mucous production and accumulation, partial or total mucus plugging of the airways, smooth bronchial airways (bronchospasm), and air trapping and hyperinflation of alveoli occasionally in late stages.
26. What are the clinical manifestations of chronic bronchitis?
Persistent productive cough with purulent mucus and yellow/green mucus if superimposed respiratory infection. As the disease progresses, increased
27. What are the two major types of bronchitis?
Simple (acute) bronchitis and chronic obstructive bronchitis.
28. What is simple (acute) bronchitis?
It is usually caused by 80% virus or bacteria with no airflow obstruction. The presentation is usually mild and self-limited and requires only supportive care. The prognosis for this type is good.
29. What are the causes of chronic obstructive bronchitis?
The major cause is cigarettes which
30. What is the prognosis for chronic obstructive bronchitis?
Premature morbidity and mortality and may have an acute exacerbation of chronic bronchitis (AECB) also known as acute on chronic.
31. What is chronic bronchitis brought on by?
Inspired irritants like cigarette smoke (for a prolonged period of time).
32. How do inspired irritants cause chronic bronchitis?
It increases mucus production and size. The number of
33. What does chronic bronchitis do to the body?
Thick, tenacious secretions (mucus) are produced that cannot be cleared. Damaged cilia where bronchial walls become inflamed and thickened edema. Accumulation of inflammatory cells and thickened smooth muscle becomes chronically hard and narrows airways (chronic
34. What parts of the lungs does chronic bronchitis affect?
It initially only affects larger bronchi but eventually, all airways are involved. Obstruction of airway results, particularly during expiration when airways are narrowed.
35. What can chronic bronchitis cause over long periods of time?
Right-sided heart failure (cor pulmonale).
36. What are the treatments for bronchitis?
Prevention and bronchodilators.
37. Is chronic bronchitis irreversible?
No. If patients stopped smoking, for example, the disease can be halted but not cured.
38. What is the difference between emphysema and chronic bronchitis?
Emphysema is the destruction of the lung tissue while chronic bronchitis is when mucus is present in the airway of the lungs.
39. What can infections do on patients with chronic bronchitis?
Bacterial and viral infections in the patient with chronic bronchitis generally exacerbate the condition. The bacterial infections cause purulent sputum because of the amounts of eosinophils and neutrophils.
40. What condition refers to a V/Q mismatch?
41. Why is pulmonary hypertension the second problem?
Hypoxemia leads to polycythemia (elevated RBC’s).
42. What does acidosis do?
It adds to the contraction of the smooth muscles in the pulmonary blood vessels.
43. When does cor pulmonale (right heart failure) happen?
It occurs in the later stages due to an increased workload on the right ventricle.
44. What are the common symptoms seen on the physical exam?
Increased cough and sputum production.
45. What is included in the sputum production of chronic bronchitis?
It includes mucoid, may be purulent, and may have hemoptysis (
46. How does shortness of breath present in chronic bronchitis patients?
Mild at first then gradually increases over time. It increases with exertion and eventually, shortness of breath persists at rest.
47. What kind of breath sounds clears with a cough?
Rhonchi because of the clearing of secretions.
48. What are the other common signs of chronic bronchitis?
Other common signs are
49. What are the medications for the treatment of chronic bronchitis?
Sympathomimetics, albuterol and
50. When can oxygen therapy be used for chronic bronchitis?
PO2 <55 mmHg on
