Question 1

Which of the following inhaled antibiotics are approved to treat a patient with cystic fibrosis
I.Tobramycin
II.Aztreonam
III.Pulmozyme
IV.Colistin

Accepted Answer

Tobramycin, Aztreonam, and Colistin are all approved inhaled antibiotics for the treatment of cystic fibrosis. Pulmozyme is not an antibiotic, but rather an inhaled medication that helps break down the thick mucus in the lungs of cystic fibrosis patients.

Question 2

What are some symptoms that Could signify the presence of cystic fibrosis
I.Difficulty gaining weight
II.Abnormal stools
III.Potassium deficiency
IV.CT scan revealing bronchiectasis and muCous plugging

Accepted Answer

Difficulty gaining weight, abnormal stools, and CT scan revealing bronchiectasis and mucus plugging are common symptoms of cystic fibrosis. Potassium deficiency is not a commonly associated symptom of cystic fibrosis. Therefore, the best choice is B, which includes the three common symptoms of cystic fibrosis.

Question 3

What is Considered the most Common life-shortening genetic disease among Caucasians

Accepted Answer

Cystic fibrosis is the most common life-shortening genetic disease among Caucasians. It affects the lungs, pancreas, and other organs, leading to progressive respiratory and digestive symptoms that can ultimately be fatal. The disease is inherited in an autosomal recessive pattern, meaning that an individual must inherit two faulty copies of the CFTR gene (one from each parent) to develop cystic fibrosis.

Question 4

Which of the following techniques are not Considered when managing a patient with cystic fibrosis I.Airway clearance technique II.Bronchial hygiene therapy III.Hig- frequency chest wall oscillation IV.Total chest breathing technique V.High-pressure positive expiratory pressure therapy VI.Drainage autogenic dyssynchrony VII.Intrapulmonary percussive ventilation VIII.Aerosol therapy and muColytic therapy

Accepted Answer

All of the techniques listed except for IV (total chest breathing technique) and VII (intrapulmonary percussive ventilation) are considered when managing a patient with cystic fibrosis. Therefore, the answer is C.

Question 5

Which of the following practices facilitate muCous clearance in patients with cystic fibrosis
I.Positive expiratory pressure therapy
II.Low-frequency inspiratory oscillation
III.Positive end-expiratory pressure therapy
IV.High-frequency expiratory oscillation

Accepted Answer

Positive expiratory pressure therapy (Option I) helps to mobilize mucus from the smaller airways to the large airways, where it can be cleared more easily. High-frequency expiratory oscillation (Option IV) can also help to loosen and mobilize mucus in the airways. Options II and III are not as effective for mucus clearance in patients with cystic fibrosis. Low-frequency inspiratory oscillation (Option II) may provide some benefit for airway clearance, but it is less effective than the other options. Positive end-expiratory pressure therapy (Option III) can help to maintain airway opening and increase lung volumes, but it does not directly facilitate mucus clearance.

Question 6

What pulmonary function test marker(s) best Correlate with instances of mortality in patients with cystic fibrosis
I.Forced vital capacity
II.Forced expiratory volume after 1 seCond divided by forced expiratory volume after 6 seConds
III.Functional residual capacity
IV.Forced expiratory volume after 1 seCond

Accepted Answer

Forced expiratory volume after 1 second (FEV1) and forced vital capacity (FVC) are the two most important pulmonary function test markers that correlate with mortality in patients with cystic fibrosis. Both of these markers are commonly used to monitor disease progression and response to treatment, and individuals with lower FEV1 and FVC values have been shown to have a higher risk of mortality.

Question 7

What is the standardized order for delivery of inhaled medications and airway clearance

Accepted Answer

The standardized order for delivery of inhaled medications and airway clearance is a bronchodilator first to open up the airways, followed by hypertonic saline to increase mucus clearance, then dornase alfa to break down thick secretions, airway clearance to remove any loosened mucus, and finally, inhaled antibiotics and inhaled steroids. Option B follows this order correctly, and hence it is the best choice.

Question 8

Which of the following are muColytic agents
I.Dornase alfa
II.Pulmozyme
III.Hypotonic saline solutions
IV.Tobramycin
V.Acetylcysteine

Accepted Answer

Dornase alfa, Pulmozyme, and Acetylcysteine are all muColytic agents that help thin out mucus, making it easier to cough up. On the other hand, Hypotonic saline solutions and Tobramycin are not muColytic agents - Hypotonic saline solutions hydrate the airways, while Tobramycin is an antibiotic used to treat infections. Therefore, the best choice is B, which includes only the three muColytic agents: I, II, and V.

Question 9

What is the most Common bacterium found in the airways of patients with cystic fibrosis

Accepted Answer

Pseudomonas aeruginosa is the most common bacterium found in the airways of patients with cystic fibrosis. It is a significant cause of lung damage and respiratory failure in these patients. Staphylococcus aureus is also commonly found, but not as frequently as Pseudomonas aeruginosa. Burkholderia cenocepacia and Methicillin-resistant Staphylococcus aureus are less common in CF patients.

Question 10

What action should be performed to stop transmission of pathogens from one cystic fibrosis patient to another

Accepted Answer

Hand washing is the most effective way of stopping transmission of pathogens from one cystic fibrosis patient to another. Disinfecting equipment and autoclave sterilization of equipment are important, but hand washing is essential in preventing cross-contamination between patients. Distillation process is not necessary in this case.

Question 11

What percentage of patients with cystic fibrosis present with bowel obstructions

Accepted Answer

Approximately 10%-15% of patients with cystic fibrosis present with bowel obstructions, often due to meconium ileus in newborns or distal intestinal obstruction syndrome in older individuals.

Question 12

What are the three phases of autogenic drainage

Accepted Answer

Autogenic drainage is a technique used in respiratory therapy that involves three phases: Unstick, Collect, and Evacuate. These phases help to loosen, collect, and remove mucus from the lungs.

Question 13

What is the reCognized testing standard for diagnosing cystic fibrosis
I.Sweat test
II.Pilocarpine iontophoresis
III.Cystic fibrosis transmembrane Conductance regulator gene sequencing
IV.Nasal potential difference

Accepted Answer

The sweat test, specifically the pilocarpine iontophoresis method, is the recognized standard for diagnosing cystic fibrosis. This test measures the concentration of chloride in the sweat, which is abnormally high in individuals with cystic fibrosis.

Question 14

What is the only FDA-approved nebulizer for use with inhaled tobramycin

Accepted Answer

The only FDA-approved nebulizer for use with inhaled tobramycin is the PARI LC PLUS nebulizer.

Question 15

What was the median survival age for patients with cystic fibrosis as of 2010

Accepted Answer

The answer of What was the median survival age for...

Question 16

Which of the following are Contraindications to lung transplantation for patients with cystic fibrosis
I.Poor adherence to therapy
II.Normal body mass index
III.UnControlled diabetes
IV.Colonization with resistant organisms

Accepted Answer

Poor adherence to therapy, uncontrolled diabetes, and colonization with resistant organisms are contraindications to lung transplantation. Normal body mass index is not a contraindication.

Question 17

What role does exercise play in improving lung function for patients with cystic fibrosis
I.Increase minute ventilation
II.Decrease minute ventilation
III.Decrease expiratory flow
IV.Increase expiratory flow

Accepted Answer

Exercise plays a role in improving lung function for patients with cystic fibrosis by increasing minute ventilation and expiratory flow. Option II and III are incorrect as exercise does not decrease minute ventilation or expiratory flow. Option I and IV are correct as exercise increases both minute ventilation and expiratory flow. Therefore, the best choices are C) I and IV.

Question 18

What information should be Considered when creating an individualized treatment plan for a patient with cystic fibrosis
I.Age
II.Gender
III.Symptoms
IV.Pulmonary function test results
V.Severity of lung disease

Accepted Answer

Age, symptoms, and the severity of lung disease are crucial factors in tailoring a treatment plan for a patient with cystic fibrosis. Age influences disease progression and treatment options, symptoms determine immediate healthcare needs, and the severity of lung disease guides the intensity of treatment. Gender, while important in some contexts, is less directly influential in individualizing cystic fibrosis treatment plans compared to these other factors.

Question 19

What percentage of adults with cystic fibrosis (CF) develop CF-related diabetes

Accepted Answer

50% of adults with cystic fibrosis develop CF-related diabetes. This is a significant complication of the disease, reflecting the impact of CF on the pancreas, where insulin is produced.

Question 20

What factors hasten the progression of lung disease in patients with cystic fibrosis
I.Infection with Pseudomonas aeruginosa
II.Infection with Burkholderia cenocepacia
III.Male patient
IV.Diabetes
V.Exposure to seCondhand smoke

Accepted Answer

Infection with Pseudomonas aeruginosa, diabetes, and exposure to secondhand smoke are all factors that have been shown to hasten the progression of lung disease in patients with cystic fibrosis. Male gender has also been associated with a slightly faster decline in lung function, although it is not considered as significant as the other factors listed. Infection with Burkholderia cenocepacia is known to be particularly aggressive in patients with cystic fibrosis, but it is not as common as Pseudomonas aeruginosa. Therefore, the best choice is A, which includes the three factors that have the strongest evidence supporting their impact on disease progression.
