A patient is hyperventilating, and suddenlyfeels ill. Which of the following are ways thebody will attempt to maintain homeostasis? (check all that apply) A. Activity will increase at thepneumotaxic center to increase the rateof breathing. B. The person will vomit to removeexcess acid in their system. C. The peripheral chemoreceptors willdetect the level of oxyhemoglobinpresent in the blood .D. The kidneys will secrete more bicarbonate ions

You measure the vital signs for Mr. Yazdani, a client you are caring for. His oxygen saturation is 87% on room air. Mr. Yazdani does not appear to be in any distress and denies having any pain or shortness of breath. You see in his previously charted vitals that the saturation was 86%. You have two other clients who require your attention, including one who has been waiting for a shower. What will you do next?

Due to polio, a patient suffers total paralysis of his muscles. For this patient, which of the following values would still be expected to be essentially normal?  a. Inspiratory reserve volume b. expiratory reserve volumec. vital capacityd. none of the abovee. total lung capacity

1.) True or False: Total Pulmonary Ventilation is always greater than Alveolar Ventilation?   True   False   2.) Negative pressure in the pleural sac is generated by __________ elastic recoil of the thoracic wall and ____________ elastic recoil of the lungs:   Inward; inward   Outward; outward   Inward; outward   Outward; inward   None of the above

Which of the following occurs for expiration to occur? a. the thoracic volume decreases b. the thoracic volume increases c. the intrapulmonary pressure decrease compared to atmospheric air pressure d. the intrapleural pressure becomes more negative

Which of the following is the most important factor regulating the respiratory rate? O A. Bicarbonate concentration of the blood. OB. Concentration of carbaminohemoglobin. OC. Partial pressure of carbon dioxide of the blood. O D. pH of systemic venous blood O E. Oxygen concentration of systemic venous blood

Describe the function of peripheral chemoreceptors as it relates to the respiratory system

75. In a healthy person who is standing, which of the following best characterizes findings in the apical regions of the lungs if compared with the basal regions? Compliance Alveolar PO2 A) B) E) Ventilation/Perfusion Ratio No change No change ↑ ↓ ↑ ↑ no change ↑ ↓ no change ↓ no change no change ↑ ↑

In the diagram below, What does H represent? a. Residual volume. b. Functional residual capacity. c. Inspiratory reserve volume. d. Vital capacity. e. Total lung capacity.

Asthma is a very common disease. It is characterized by widespread narrowing of the bronchioles and formation of mucus plugs, producing symptoms of wheezing, shortness of breath, and coughing, and is caused by the release of factors during an allergic response. Explain why the narrowing of bronchioles, rather than that of the larger bronchi, is the source of the airflow restriction, and why inhaling dilating agents can bring relief during an asthma attack.
