NBRC Certified Respiratory Therapist - FAQ Sample Questions

Which of the following is least likely to be a sign or symptom of bronchiectasis?

Correct Answer:
increased fvc


bronchiectasis is a chronic pulmonary condition characterized by the permanent enlargement and destruction of the bronchial tubes. this condition leads to symptoms and signs that are indicative of respiratory system dysfunction. to understand which of the given options is least likely to be a sign or symptom of bronchiectasis, it's crucial to have a basic understanding of common manifestations of the disease and how lung function is typically affected.

firstly, considering the option of "increased fvc" or forced vital capacity, this is unlikely to be associated with bronchiectasis. in bronchiectasis, the lung's airways are damaged and scarred, which typically leads to a decrease in the amount of air that can be forcibly exhaled from the lungs. therefore, both fvc and other related spirometry measurements such as fev1 (forced expiratory volume in one second) and fef25%-75% (forced mid-expiratory flow rate) are generally reduced, not increased. this reduction in lung function is due to the obstruction or collapse of the airways and loss of elasticity in the lung tissue.

the other options listed—including barrel chest, recurrent pulmonary infections, and digital clubbing—are indeed commonly associated with bronchiectasis. a "barrel chest" can develop as a result of the chronic hyperinflation of lungs, which is common in many chronic pulmonary diseases including bronchiectasis. recurrent pulmonary infections occur due to the inability to clear mucus from the bronchi, providing a breeding ground for bacteria and viruses. digital clubbing, a deformity of the fingers and fingernails, is a sign of chronic hypoxia, a condition often seen in patients with significant bronchiectasis due to poor air exchange.

in summary, while recurrent pulmonary infections, digital clubbing, and barrel chest are symptoms or signs often seen in bronchiectasis, an increased fvc is not typical of this condition. instead, decreased fvc and other measures of lung function are characteristic findings, reflecting the impaired pulmonary mechanics associated with bronchiectasis. thus, "increased fvc" is the correct answer as the least likely sign or symptom of bronchiectasis among the options provided.

Diseases such as pulmonary fibrosis and pneumonia typically result in which of the following study results?

Correct Answer:
decreased frc


diseases such as pulmonary fibrosis and pneumonia typically result in decreased functional residual capacity (frc). frc refers to the volume of air that remains in the lungs after a normal exhalation. when the lung tissue is damaged by fibrosis or inflamed due to pneumonia, the lungs lose their elasticity and become stiffer. this stiffness restricts the lungs' ability to expand, resulting in a lower volume of air being held in the lungs at the end of a passive exhalation.

pulmonary fibrosis specifically involves the thickening and scarring of lung tissue, which directly limits the lungs' ability to expand during inhalation. pneumonia, an inflammatory condition primarily affecting the alveoli, leads to the filling of these air sacs with fluid or pus, making the exchange of oxygen and carbon dioxide difficult and reducing lung capacity. both conditions are categorized under restrictive lung diseases due to their nature of limiting lung expansion.

as a result of reduced lung expansion in diseases like pulmonary fibrosis and pneumonia, other lung volumes and capacities are also typically affected. forced vital capacity (fvc), which is the total amount of air exhaled during a forced breath, is usually decreased because of the reduced lung tissue compliance. inspiratory capacity (ic), the maximum amount of air that can be inhaled after a normal exhalation, and inspiratory reserve volume (irv), the additional air that can be forcibly inhaled after a normal inhalation, are also decreased due to the inability of the lungs to fully expand.

however, the ratio of forced expiratory volume in one second to forced vital capacity (fev1/fvc), also known as fev/vvc, typically remains normal or even increased in restrictive diseases like fibrosis and pneumonia. this is because both the fev1 and fvc are reduced proportionally due to the restrictive nature of the diseases, maintaining or increasing the ratio. this contrasts with obstructive diseases, where fev1 is disproportionately reduced due to airway obstruction, leading to a lower fev1/fvc ratio.

in summary, pulmonary fibrosis and pneumonia lead to a decrease in frc as well as other lung volumes like fvc, ic, and irv due to the stiffening and reduced compliance of lung tissue. however, the fev1/fvc ratio often remains within the normal range, helping to differentiate restrictive lung diseases from obstructive ones in pulmonary function tests.
