- Ischemic hypoxia is the result of: inability of the cells to use oxygen compromised oxygen transport due to blockage or constriction of blood vessels substitution of oxygen by another substance, e.g. carbon monoxide compromised ability of oxygen tansport due to low hemoglobin low environmental oxygenPleural membranes surround the lungs. These membranes serve as the glue between the lungs and the thoracic cavity. Which of the following statements is correct about these structures? The visceral pleura lines the outside of the lungs, the parietal pleura lines the thoracic cavity, and the intrapleural space seals the two layers together The parietal pleura lines the outside of the lungs, the visceral pleura lines the thoracic cavity, and the intrapleural space seals the two layers together The thoracic cavity and lungs are only connected by the visceral pleura The thoracic cavity and lungs are only connected by the parietal pleuraThe function of the respiratory system is closely tied to its structure and organization. choose one component of the respiratory system and discuss how it's structure helps it to carry out it's function following the instructions below: Choose one disorder that affects the structure you discussed. Make sure to address the cause of the disorder, signs and symptoms the patient is experiencing, how it is eventually diagnosed, and finally treatment. Extend the discussion further by considering how the different disorders affect other systems in the body, as well as the respiratory tract.

- A respiratory therapist must draw arterial blood from a patient before O2 therapy can be initiated. True or FalseExplain why caution must be used when performing radiographic procedures on patients receiving oxygen therapy (administration)An 83-year-old woman is admitted to the hospital, where a critical care nurse attempts to insert a nasoenteric tube (“stomach tube”) for feeding. The patient begins to exhibit dyspnea, and a chest X-ray reveals air in the right pleural cavity and a collapsed right lung. The patient dies 5 days later from respiratory complications. Name the conditions revealed by the X-ray and explain how they could have resulted from the nurse’s procedure.
- A 22-year-old man is brought to the emergency department in respiratory distress 15 minutes after he was stung on the arm by a wasp. His pulse is 100/min, respirations are 30/min, and blood pressure is 100/60 mm Hg. Physical examination shows grunting respirations and subcostal retractions. Expiratory wheezes are heard over both lung fields. There is generalized urticaria. Secretion of the molecule causing this patient's symptoms is most likely mediated by which of the following? (A) Activation of complement (B) Activation of mast cell (C) Activation of T lymphocytes (D) Production of IgA (E) Production of IgG (F) Production of IgMA patient of 50 years old suffers from chronic obstructive bronchitis. Recently, after hypothermia, the patient had a cough with purulent sputum, dyspnea, weakness. On examination: acrocyanosis, blood pressure 140/90, heart rate 100 beats per minute (normally 60-90), respiration is frequent and superficial. At auscultation: there are wet wheezing in the lower lobe of the right lung. Questions: 4. Describe the mechanism of development of this TPP in the patient. 5. Describe the most likely changes in blood gas composition and pH in this case. 6. What signs of adaptive reactions are there in the patient? 7. What other adaptive reactions are typical for this type of TPP?A patient of 50 years old suffers from chronic obstructive bronchitis.
