What two diseases are included in COPD?
Correct Answer
B. Chronic bronchitis and empHysema
Explanation
COPD stands for Chronic Obstructive Pulmonary Disease, which is a group of lung diseases that cause breathing difficulties. The two main diseases included in COPD are chronic bronchitis and emphysema. Chronic bronchitis is characterized by inflammation and narrowing of the bronchial tubes, leading to excessive mucus production and coughing. Emphysema, on the other hand, involves damage to the air sacs in the lungs, causing them to lose their elasticity and making it difficult to exhale properly. Both diseases contribute to the obstruction of airflow and result in symptoms such as shortness of breath and wheezing.
2.
COPD is characterized by the presence of ____________ _______________ as a result of either of these two disease states. It is very similar to asthma.
Correct Answer
B. Airflow obstruction
Explanation
COPD is a chronic lung disease that is similar to asthma. It is characterized by the presence of airflow obstruction, which can occur due to either of the two disease states. This obstruction refers to a narrowing or blockage of the airways, leading to difficulty in breathing and reduced airflow.
3.
What two pulmonary diseases together represent the fourth leading cause of death in the US, with over 100,000 deaths reported annually.
Correct Answer
B. COPD and Asthma
Explanation
COPD (Chronic Obstructive Pulmonary Disease) and Asthma together represent the fourth leading cause of death in the US, with over 100,000 deaths reported annually. COPD is a chronic inflammatory lung disease that obstructs airflow, while asthma is a chronic condition characterized by inflammation and narrowing of the airways. Both diseases can lead to difficulty breathing and reduced lung function, making them significant contributors to mortality rates in the US.
4.
Most patients with COPD have features of BOTH chronic bronchitis and emphysema
Correct Answer
A. True
Explanation
Most patients with COPD have features of BOTH chronic bronchitis and emphysema because COPD is a progressive lung disease that affects the airways and the air sacs in the lungs. Chronic bronchitis is characterized by inflammation and narrowing of the airways, leading to excessive mucus production and coughing. Emphysema, on the other hand, involves damage to the air sacs, causing them to lose their elasticity and making it difficult to exhale air. Both conditions commonly coexist in patients with COPD, leading to symptoms such as shortness of breath, wheezing, and coughing. Therefore, it is true that most patients with COPD have features of both chronic bronchitis and emphysema.
5.
Cigarette smoking has nothing to do with COPD.
Correct Answer
B. False
Explanation
The statement "Cigarette smoking has nothing to do with COPD" is false. COPD, or Chronic Obstructive Pulmonary Disease, is primarily caused by long-term exposure to irritants such as cigarette smoke. Smoking is the leading cause of COPD, and it significantly increases the risk of developing the disease. Therefore, there is a strong association between cigarette smoking and COPD.
6.
Which disease is anatomically defined as an abnormal permanent enlargement of the air spaces distal to the terminal bronchioles, accompanied by destruction of the bonchiolar walls and the alveolar septa?
Correct Answer
B. EmpHysema
Explanation
Emphysema is an anatomically defined disease characterized by the abnormal permanent enlargement of the air spaces distal to the terminal bronchioles. This enlargement is accompanied by the destruction of the bronchiolar walls and the alveolar septa. Chronic bronchitis, on the other hand, is characterized by the inflammation and narrowing of the bronchial tubes, leading to excessive mucus production and coughing. Therefore, based on the description provided, emphysema is the correct answer.
7.
Patients with emphysema have increased lung compliance.
Correct Answer
A. True
Explanation
Patients with emphysema have increased lung compliance because emphysema is a condition characterized by the destruction of the alveolar walls, leading to the loss of elasticity in the lungs. This loss of elasticity allows the lungs to expand more easily, resulting in increased lung compliance. As a result, the lungs are able to hold more air and have a higher capacity for inhalation and exhalation.
8.
Patients with which disease are known as "pink puffers"
Correct Answer
A. EmpHysema
Explanation
Patients with emphysema are known as "pink puffers" because they often have a pink or flushed complexion due to increased respiratory effort. Emphysema is a chronic lung condition characterized by the destruction of the air sacs in the lungs, leading to difficulty in exhaling and reduced oxygen exchange. These patients often have pursed-lip breathing and use accessory muscles to breathe, resulting in increased respiratory effort. The term "pink puffers" differentiates emphysema from "blue bloaters," which refers to patients with chronic bronchitis who often have a bluish complexion due to inadequate oxygenation.
9.
You are presented an x ray with an increased blackness, increased retro-sternal space, a small heart, and a depressed, flattened diaphragm, and the presence of blebs. The patient is complaining of dyspnea that is severe and occurs early. Physical exam appears normal. What diagnosis is suspected?
Correct Answer
B. EmpHysema
Explanation
The given x-ray findings of increased blackness, increased retro-sternal space, small heart, depressed flattened diaphragm, and the presence of blebs suggest emphysema. Emphysema is a type of chronic obstructive pulmonary disease (COPD) characterized by the destruction of the alveoli in the lungs, leading to air trapping and hyperinflation. This results in increased blackness on the x-ray due to increased air in the lungs. The small heart is a consequence of the hyperinflated lungs pushing against the heart. The depressed flattened diaphragm is a result of the loss of lung elasticity. The presence of blebs, which are air-filled spaces within the lung tissue, is a characteristic finding in emphysema. The severe dyspnea that occurs early is a common symptom of emphysema.
10.
What is the earliest symptom of COPD?
Correct Answer
C. Daily morning cough with clear sputum
Explanation
The earliest symptom of COPD is a daily morning cough with clear sputum. This symptom occurs due to the inflammation and irritation in the airways caused by COPD. The cough is usually persistent and occurs every morning. The sputum produced is clear because it does not contain any infection or mucus buildup. As the disease progresses, the cough may worsen and the sputum may become yellow or green, indicating the presence of infection or mucus.
11.
When do you order an ABG on a COPD patient? (click all that apply)
Correct Answer(s)
A. When hypoxemia or hypercapnia is suspected
B. FEV1 < 40%
D. If there are clinical signs of right heart failure
Explanation
An arterial blood gas (ABG) is ordered on a COPD patient when hypoxemia or hypercapnia is suspected, as these are common complications of COPD. Additionally, an ABG may be ordered if the patient has a FEV1 (forced expiratory volume in 1 second) less than 40%, as this indicates severe airflow obstruction. Clinical signs of right heart failure may also warrant an ABG, as it can help assess the patient's oxygenation and acid-base balance. Therefore, the correct answer includes all of these criteria.
12.
What lab test do you order on the sputum sample of a COPD patient?
Correct Answer
B. Culture and gram stain
Explanation
The correct answer is culture and gram stain because this test is commonly ordered on sputum samples of COPD patients to identify the presence of bacteria and determine their sensitivity to antibiotics. Culture helps in growing the bacteria present in the sample, while gram stain helps in identifying the type of bacteria based on their cell wall structure. This information is crucial for selecting the appropriate antibiotic treatment for the patient.
13.
What are the common pathogens present in the sputum of a COPD patient?
Correct Answer
A. Streptococcus pneumonia, HaemopHilus influenzae, Moraxella catarrhalis
Explanation
The common pathogens present in the sputum of a COPD patient are Streptococcus pneumonia, Haemophilus influenzae, and Moraxella catarrhalis. These bacteria are frequently found in the respiratory tract of patients with COPD and can cause exacerbations of the disease. Streptococcus pneumoniae is a common cause of pneumonia and can also lead to worsening symptoms in COPD patients. Haemophilus influenzae is another common respiratory pathogen that can cause infections in COPD patients. Moraxella catarrhalis is a bacterium that is often associated with respiratory infections, particularly in individuals with underlying lung conditions like COPD.
14.

Correct Answer
B. An excess of red blood cells
Explanation
due to an increased red blood cell count to compensate for hypoxemia
15.
What are the common EKG abnormalities seen in a COPD patient?
Correct Answer(s)
A. Multifocal atrial tachycardia
B. Atrial flutter
C. Atrial fibrillaitons
D. Low voltage and right axis deviation, poor R wave progression
Explanation
Common EKG abnormalities seen in a COPD patient include multifocal atrial tachycardia, atrial flutter, atrial fibrillations, low voltage, right axis deviation, and poor R wave progression. These abnormalities are often a result of the structural and functional changes in the heart that occur due to the chronic lung disease. The multifocal atrial tachycardia is characterized by irregular and rapid heartbeats originating from multiple foci in the atria. Atrial flutter and fibrillations refer to abnormal and chaotic electrical activity in the atria. Low voltage and right axis deviation, along with poor R wave progression, are indicative of changes in the electrical conduction system of the heart.
16.
What are possbile complicatons of COPD?
Correct Answer
A. Pulmonary hypertension, cor pulmonale, and chronic respiratory failure, and pulmonary embolism
Explanation
Possible complications of COPD include pulmonary hypertension, cor pulmonale, chronic respiratory failure, and pulmonary embolism. These complications can arise due to the progressive nature of COPD, which leads to chronic inflammation and damage to the airways and lungs. Pulmonary hypertension refers to high blood pressure in the arteries of the lungs, which can strain the heart. Cor pulmonale is a condition where the right side of the heart becomes enlarged and weakened due to lung disease. Chronic respiratory failure occurs when the lungs are unable to provide enough oxygen and remove enough carbon dioxide from the blood. Pulmonary embolism refers to a blockage in the pulmonary arteries, usually caused by a blood clot.
17.
What vaccines should you recommend to a patient with COPD?
Correct Answer
B. Pneumococcal vaccine and yearly influenza vaccine
Explanation
Patients with chronic obstructive pulmonary disease (COPD) are at increased risk for respiratory infections, including pneumonia and influenza. Therefore, it is recommended to administer both the pneumococcal vaccine and the influenza vaccine to these patients on a yearly basis. The pneumococcal vaccine helps protect against pneumococcal infections, including pneumonia, while the influenza vaccine helps prevent seasonal flu, which can exacerbate COPD symptoms and lead to complications. By recommending both vaccines, healthcare providers can help reduce the risk of infections and improve the overall health of patients with COPD.
18.
What is the worst stage of COPD?
Correct Answer
C. Stage III- FEV1 < 30%
Explanation
Range is from 0-III (with a moderate= IIA and IIB)
19.
The cornerstone of treatment of asthma is inhaled corticosteroids, what is the treatment for patients with COPD after smoking cessation has been discussed?
Correct Answer
A. Supplemental oxygen (home) on a rate of 1-3 meters to achieve a PaO2 > 55 mm Hg
Explanation
After smoking cessation, patients with COPD may require supplemental oxygen therapy to maintain adequate oxygen levels in the blood. The goal is to achieve a PaO2 (partial pressure of oxygen in arterial blood) level greater than 55 mm Hg. This can be achieved by providing supplemental oxygen at a flow rate of 1-3 liters per minute through a nasal cannula or other oxygen delivery device. This therapy helps improve oxygenation and reduce symptoms in patients with COPD.
20.
T/F Bupropion (Wellbutrin) is a treatment option for smoking cessation in motivated patients
Correct Answer
A. True
Explanation
Bupropion, also known as Wellbutrin, is indeed a treatment option for smoking cessation in motivated patients. It is an antidepressant medication that is also used to help individuals quit smoking by reducing cravings and withdrawal symptoms. Bupropion works by affecting the chemicals in the brain that are related to nicotine addiction. Therefore, it can be an effective tool in helping motivated individuals quit smoking.
21.
What two bronchodilators are most often prescribed for patients with COPD?
Correct Answer
A. Atrovent (anti-cholinergic ipratropium bromide) and albuterol (short-acting beta agonists)
Explanation
Atrovent (anti-cholinergic ipratropium bromide) and albuterol (short-acting beta agonists) are the most often prescribed bronchodilators for patients with COPD. Atrovent works by relaxing the muscles in the airways, allowing them to open up and improve airflow. Albuterol, on the other hand, stimulates the beta receptors in the airways, causing the muscles to relax and allowing for easier breathing. These two medications work together to provide relief from the symptoms of COPD, such as wheezing and shortness of breath.
22.
T/F Albuterol is the primary drug for asthma and atrovent is for COPD, but both are used in both conditions
Correct Answer
A. True
Explanation
Both albuterol and atrovent are bronchodilators commonly used to treat respiratory conditions such as asthma and COPD. While albuterol is considered the primary drug for asthma, and atrovent is typically used for COPD, it is important to note that both medications can be used in both conditions. This is because both asthma and COPD involve airway constriction and inflammation, and both albuterol and atrovent work to relax the airway muscles and improve breathing. Therefore, it is true that both albuterol and atrovent can be used in both asthma and COPD.
23.
T/F MDIs are contraindicated in patients with a peanut or soy allergy?
Correct Answer
A. True
Explanation
MDIs, or metered-dose inhalers, are contraindicated in patients with a peanut or soy allergy. This is because some MDIs contain propellants or excipients derived from peanut or soy sources, which can trigger an allergic reaction in individuals with these allergies. Therefore, it is important for healthcare providers to consider alternative inhaler options for patients with peanut or soy allergies to ensure their safety and avoid any potential adverse reactions.
24.
T/F Corticosteroids are useful for patients with COPD
Correct Answer
B. False
Explanation
Corticosteroids are not useful for patients with COPD. While they can be effective in managing symptoms and reducing inflammation in patients with asthma, they have limited benefits for COPD patients. In fact, studies have shown that corticosteroids may increase the risk of pneumonia and other respiratory infections in COPD patients. Therefore, the statement is false.
25.
What two symptoms of a COPD flare suggest that you should put them on an antibiotic?
Correct Answer
B. Dyspnea and change in quantitiy or character of sputum
Explanation
Dyspnea, which refers to difficulty in breathing, is a common symptom of a COPD flare. When a patient with COPD experiences a change in the quantity or character of their sputum, such as an increase in production or a change in color, it suggests the presence of a bacterial infection. Therefore, putting the patient on an antibiotic would be appropriate in this situation to treat the infection and prevent further complications.
26.
What antibiotic do you prescribe for patients with a flare of COPD
Correct Answer
C. Bactrim
Explanation
Bactrim is the correct answer for prescribing antibiotics to patients with a flare of COPD. Bactrim is a combination of sulfamethoxazole and trimethoprim, which are effective against a wide range of bacteria. It is commonly used to treat respiratory infections, including those associated with COPD exacerbations. Bactrim works by inhibiting the growth of bacteria, reducing inflammation, and improving symptoms. It is important to note that the choice of antibiotic may vary based on individual patient factors and local resistance patterns, so consulting with a healthcare professional is advised.
27.
T/F You have to consider withholding oxygen therapy to avoid worsening respiratory acidemia

28.
Which of the following should you consider regarding intubating a patient with COPD?
Correct Answer
B. Hold of intubating and try NPPV noninvasive positive-pressure ventilation delivered by face mask to reduce the need for intubating
Explanation
Patients with COPD often have difficulty breathing due to airway obstruction and impaired lung function. Intubating a patient with COPD should be done cautiously and only when necessary, as it can worsen their condition and lead to complications. Instead, noninvasive positive-pressure ventilation (NPPV) delivered by a face mask should be attempted first to support their breathing and reduce the need for intubation. This approach helps to maintain oxygenation and ventilation while minimizing the risks associated with invasive intubation.
29.
T/F Cystic fibrosis is an autosomal dominant disorder?
Correct Answer
B. False
Explanation
False- it is autosomal recessive
30.
Which disease is caused by abnormalities in a membrane chloride channel that results in altered chloride transport and water flux across the apical surface of epithelial cells
Correct Answer
B. Cystic fibrosis
Explanation
Cystic fibrosis is caused by abnormalities in a membrane chloride channel, specifically the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This protein is responsible for regulating chloride transport and water flux across the apical surface of epithelial cells. In individuals with cystic fibrosis, the CFTR protein is defective or absent, leading to impaired chloride transport and reduced water movement. This results in the production of thick, sticky mucus in various organs, leading to the characteristic symptoms and complications associated with cystic fibrosis.
31.
At what age do symptoms of cystic fibrosis occur?
Correct Answer
A. 1 year
Explanation
Cystic fibrosis is a genetic disorder that affects the lungs and other organs. Symptoms of cystic fibrosis typically occur within the first year of life. This includes respiratory issues such as persistent coughing, wheezing, and frequent lung infections. Other symptoms may include poor growth, difficulty gaining weight, and salty-tasting skin. Early diagnosis and treatment are crucial for managing the condition and improving the quality of life for individuals with cystic fibrosis.
32.
A 7 month old female presents with wheezing, dyspnea, chronic cough, nasal polyps, greasy stools and poor growth. What diagnosis are these symptoms consistent with?
Correct Answer
D. Cystic fibrosis
Explanation
The given symptoms of wheezing, dyspnea, chronic cough, nasal polyps, greasy stools, and poor growth are consistent with the diagnosis of cystic fibrosis. Cystic fibrosis is a genetic disorder that affects the lungs and digestive system. It causes the production of thick, sticky mucus that can clog the airways, leading to wheezing, dyspnea, and chronic cough. Nasal polyps can also occur due to the buildup of mucus. The greasy stools are a result of poor absorption of nutrients in the digestive system. Additionally, poor growth is a common symptom of cystic fibrosis due to the malabsorption of nutrients.
33.
Cystic fibrosis is a restricting and obstructive disease?
Correct Answer
A. True
Explanation
Cystic fibrosis is a genetic disorder that primarily affects the lungs and digestive system. It is characterized by the production of thick, sticky mucus that can clog the airways and obstruct the flow of air in and out of the lungs. This obstruction leads to restricted breathing and can cause various respiratory symptoms such as coughing, wheezing, and shortness of breath. Additionally, the mucus can also obstruct the pancreas, preventing the release of digestive enzymes and leading to problems with nutrient absorption. Therefore, cystic fibrosis can be considered a restricting and obstructive disease.
34.
What test is the gold standard for diagnosing cystic fibrosis?
Correct Answer
C. Quantitative pilocarpine iontopHoresis sweat test (sweat test)
Explanation
The gold standard for diagnosing cystic fibrosis is the quantitative pilocarpine iontophoresis sweat test, also known as the sweat test. This test measures the amount of chloride in the sweat, as individuals with cystic fibrosis have higher levels of chloride due to a faulty chloride channel in their cells. By quantifying the chloride levels in the sweat, doctors can accurately diagnose cystic fibrosis.
35.
Which of the following result from a sweat test is considered to be diagnostic of cystic fibrosis?
Correct Answer
D. > 60mEq/L
Explanation
A sweat test is used to diagnose cystic fibrosis, a genetic disorder that affects the lungs and digestive system. In this test, the amount of chloride in the sweat is measured. A result of > 60mEq/L is considered diagnostic of cystic fibrosis because it indicates a high level of chloride, which is characteristic of the condition. Lower levels of chloride would suggest a different diagnosis.
36.
How do you clear lower airway secretions for cystic fibrosis patients?
Correct Answer(s)
A. Directed cough
B. Postural drainage
D. Chest percussion
E. Vibration techniques
Explanation
For cystic fibrosis patients, clearing lower airway secretions is crucial. Directed cough involves teaching the patient to cough effectively, which helps to expel mucus from the airways. Postural drainage involves positioning the patient in specific positions to allow gravity to assist in draining mucus from different areas of the lungs. Chest percussion involves using rhythmic clapping or tapping on the chest to loosen and mobilize mucus, making it easier to cough up. Vibration techniques involve using a vibrating device or hands to create vibrations on the chest wall, helping to loosen and move mucus. These techniques combined help to clear the airway secretions and improve respiratory function in cystic fibrosis patients.
37.
What infectious agents are common in cystic fibrosis patients that have active airway infections?
Correct Answer(s)
B. StapHylococcus aureus
C. Pseudomonas aeruginosa
D. HaemopHilus ingluenzae
E. Stenotrohomanas maltopHilia and burkholderia cepacia are occasionally isolated
Explanation
In cystic fibrosis patients with active airway infections, common infectious agents include staphylococcus aureus, pseudomonas aeruginosa, and haemophilus influenzae. Occasionally, stenotrohomanas maltophilia and burkholderia cepacia may also be isolated.
38.
What diet recommendations are suggested for cystic fibrosis patients?
Correct Answer(s)
B. Liberal salting of foods
D. High protein and high calorie diets (1.5 times the recommended normal intake)
E. Double vitamin supplements
Explanation
Cystic fibrosis is a genetic disorder that affects the lungs and digestive system. Patients with cystic fibrosis often have difficulty absorbing nutrients from food. Therefore, it is recommended for them to have a high protein and high-calorie diet, consuming 1.5 times the recommended normal intake. This helps to compensate for the poor nutrient absorption and maintain a healthy weight. Additionally, double vitamin supplements are suggested to ensure that patients are getting adequate amounts of essential vitamins and minerals. Liberal salting of foods is also recommended as cystic fibrosis patients tend to lose more salt in their sweat, which can lead to electrolyte imbalances.
39.
What drugs do you prescribe to patients with cystic fibrosis?
Correct Answer
B. Pulmozyme and mucomyst
Explanation
Pulmozyme and Mucomyst are the drugs prescribed to patients with cystic fibrosis. Pulmozyme is an enzyme that helps in thinning the mucus in the lungs, making it easier to cough up. Mucomyst is a mucolytic agent that breaks down the thick mucus, reducing the risk of lung infections. These drugs are commonly used in the management of cystic fibrosis to improve lung function and reduce respiratory complications.
