Crackles
Which of the following conditions can cause a decrease in the efficiency of the immune system, leading to respiratory complications in older adults?
Drier and more fragile mucous membranes
Which of the following respiratory conditions is characterized by the inability to breathe easily unless sitting upright or standing?
Orthopnea
Which of the following respiratory conditions is caused by the aspiration of stomach contents into the lungs, often leading to bronchospasm?
Gastroesophageal reflux disease
Which of the following respiratory conditions is characterized by reduced oxygen levels in the blood, potentially caused by conditions that impair diffusion at the alveolar–capillary level?
Hypoxemia
Which of the following respiratory conditions is characterized by the lack of blood supply due to obstructed circulation, potentially leading to tissue necrosis and death?
Infarction
Why is it important to avoid brisk, low-volume breaths when using a flow-oriented device?
Low-volume breaths do not maintain alveolar ventilation effectively.
How does a very slow inspiration differ from a brisk, shallow breath in terms of lung expansion?
A very slow inspiration achieves greater lung expansion.
What is the significance of sustained elevation of the balls or cylinder in a spirometer?
It ensures proper oxygenation of the alveoli.
In what scenario would using a nose clip be beneficial when using a spirometer?
When having trouble breathing only through the mouth.
Why is it essential to take normal breaths before using the spirometer again?
To prevent atelectasis.
Which of the following diagnostic tests is used to analyze respiratory secretions for the presence of microorganisms?
Sputum and throat culture specimens
What is the primary purpose of an arterial blood gas analysis?
To assess the oxygenation status and acid-base balance
Which diagnostic test is used to measure lung volumes, capacities, and airflow rates?
Pulmonary function tests
What is the primary purpose of a chest X-ray in the assessment of respiratory function?
To visualize the airways and lungs for structural abnormalities
Which diagnostic procedure involves the direct visualization of the airways using a flexible endoscope?
Bronchoscopy
Which of the following techniques is commonly used to obtain a sputum sample?
Induced sputum production
What is the primary purpose of performing an arterial blood gas analysis?
To measure the levels of oxygen and carbon dioxide in the blood
Which of the following tests is primarily used to measure lung volumes and capacities?
Pulmonary function testing
