What are some factors that make the respiratory system prone (more likely) to infections?
What natural safeguards are there to prevent lower respiratory tract infections?
Step by step
Solved in 2 steps
- 59) Type II alveolar cells (pneumocytes) play a crucial role in the respiratory system due to A) their ability to allow gas to diffuse into the pulmonary capillaries B) secrete a substance which prevents the alveoli from collapsing pulmonary surfactant C) remove harmful material which may lead to infection D) engulf debris through phagocytosisIn smokers, these "branches" in the lungs are often clogged and it results in decreased lung capacity: A) Bronchial TubesB) CapillariesC) VeinsD) TracheaA patient is admitted with a puncture wound to the chest and a deflated right lung. Which of the following must be punctured for a deflated lung? A) Visceral pleura B) Parietal pleura C) Pleural space D) Both A and C E) Both B and C F) All of the above
- What are the key factors that contribute to the increased susceptibility of certain individuals, such as the elderly or those with pre-existing respiratory conditions, to severe respiratory infections, and how can a deeper understanding of these factors inform the development of targeted preventive measures and treatments?During a long distance transfer of a 10 year old patient strugglign to breathe, you find him becoming quieter and acting tired. He seems like he is beginning to go to sleep. What should the provider think of this behavior? A) This is normal for a 10 year old B) He is compensating for high CO2 levels C) He is becoming more comfortable with his surroundings D) His condition is worseningA 60-year-old man has been experiencing chronic respiratory symptoms such as cough and shortness of breath. Pulmonary function tests show decreased lung compliance. Histological examination of lung tissue reveals thickened alveolar walls and an excess deposition of collagen fibers. Which disease is most likely causing these findings? a) Idiopathic pulmonary fibrosis b) Asthma c) Emphysema d) Tuberculosis

The nurse understands that oxygen therapy is primarily aimed at: a) Decreasing airway inflammation b) Improving gas exchange and relieving hypoxemia c) Preventing bronchospasm d) Reducing mucus production.3) An increased Pco2 leads to a(n): A) increased respiratory rate B) decreased respiratory rate C) no change in respiratory rateCh. 5: The obstructive lung disease in which lung tissue loses its elasticity, leading to alveolar and bronchiolar collapse, is called: a) pneumonia b) tuberculosis Oc) bronchitis d) asthma O e) emphysema
