- Question 60 You embark on a hiking trip on Mt. Kilimanjaro (altitude = 19,000 ft; Atmospheric air pressure = 379 mmHg). As you ascend, what happens to the PO 2 in the alveoli? No change from sea level, as long as we breathe in the same volume of air. Alveolar PO, decreases. Alveolar PO 2 increases.I need help with a respiratory question, thank you, I really appreciate it Stroke volume can be calculated using which formula? Group of answer choices End-diastolic volume – end-systolic volume Ejection fraction × heart rate Ejection fraction × end-systolic volume Cardiac output ÷ end-diastolic volumeQuestion 42 During your morning assessment of a client with asthma, you find her oxygen saturation is 88% on 2L/minute of oxygen via nasal cannula. What is the best way to deliver oxygen therapy to this client to obtain an oxygen saturation greater than 90%? Question 42 options: Apply a partial rebreather mask at 8L/minute Leave the oxygen at 2L/minute via nasal cannula Apply a Venturi (venti) mask at 28% oxygen Increase the flow rate of the nasal cannula to 10L/minute
- Question 46 Which of the following would specifically increase capillary hydrostatic pressure, resulting in edema? Question 46 options: inflammation starvation / malnutrition heart failure lymphatic obstructionCalculate the volume needed!!! I need to calculate volume for an experiment in laboratory. And I dont know why im confused about the questions. I have uploaded the questions, and there is also an apendix they have given us, I dont know if its nedeed to calculate these volumes''???If the Mitral Valve failed in a patient, would the blood flow back into the Right Ventricle? Question 6 options: Only if the pulmonary semilunar valves also fail Only if the aortic semilunar valves also fail No, because the flow would be stopped by the bicuspid valve No, because blood can only flow forward, never in the reverse direction.
- Which of these values would normally bethe highest?a. tidal volumeb. inspiratory reserve volumec. expiratory reserve volumed. residual volumee. vital capacityQuestion 1 A Explain how the manifold design of arteries and arterioles/capillaries regulate velocity of blood flow, and how the manifold design helps to optimize bulk transport in the main arteries, and diffusion transport in the arterioles/capillaries.QUESTION 19 True or False? With age, the walls of the arteries become more elastic, making it harder to maintain blood pressure, and blood pressure tends to decrease. True False
- Why closed suction in mechanically ventilated patient is less painful compared to open suction ?Question 6 In patients with pulmonary fibrosis, alveolar thickness is increased (due to tissue necrosis), and the alveolar area is reduced. Explain how increased alveolar thickness and the decreased area would affect the diffusion of oxygen from lung alveoli into capillary blood. (Use Fick’s equation to explain how oxygen diffusion will be affected when alveolar thickness increases and area decreases).Question 28 During an acute exacerbation of asthma (asthma attack), patients may initially suffer from respiratory alkalosis as a result of: Question 28 options: Hyperventilation Bronchoconstriction Carbon dioxide retention Hypoxemia
