![]() a decrease in respiratory rate and depth causes carbon dioxide accumulation in the alveoli and an overall decrease in blood oxygen levels.Ĭ. blood coming from the right side of the heart bypasses nonfunctional alveoli and returns to the left side of the heart in an unoxygenated state.ī. A 40-year-old unconscious patient with slow, shallow respirations Intrapulmonary shunting occurs when:Ī. A 40-year-old unconscious patient with slow, shallow respirations D. A 33-year-old semiconscious patient with reduced tidal volumeĭ. A 64-year-old conscious patient with rapid and deep respirationsĬ. A 51-year-old confused patient with severely labored respirationsī. ![]() Which of the following patients would MOST likely require insertion of an oropharyngeal airway?Ī. inadequate oxygen to the tissues and cells. high oxygen levels in the tissues and cells. inadequate oxygen to the tissues and cells.ĭ. an increase in carbon dioxide in the blood.Ĭ. With positive-pressure ventilation, more volume is required to have the same effects as normal breathing. Positive-pressure ventilation allows blood to naturally be pulled back to the heart from the body. With positive-pressure ventilation, more volume is required to have the same effects as normal breathing.ĭ. To prevent hypotension, the EMT should increase the rate and force of positive-pressure ventilation.Ĭ. Unlike negative-pressure ventilation, positive-pressure ventilation does not affect the esophageal opening pressure.ī. Which of the following statements regarding positive-pressure ventilation is correct?Ī. slight increases in carbon dioxide or a decrease in the pH of the cerebrospinal fluid. increased levels of oxygen in the blood and a decrease in the pH of the cerebrospinal fluid. slight decreases in carbon dioxide and an increase in the pH of the cerebrospinal fluid.ĭ. decreased levels of oxygen in the blood and an increase in the pH of the cerebrospinal fluid.Ĭ. slight increases in carbon dioxide or a decrease in the pH of the cerebrospinal fluid.ī. Central chemoreceptors located in the medulla provide feedback to increase the rate and depth of breathing when they sense:Ī. ensure that the correct regulator is used for the cylinder. reduce the cylinder pressure to a safe and more useful range. prevent destroying or stripping the threads on the cylinder.ĭ. ensure that the correct regulator is used for the cylinder.Ĭ. help you determine what type of oxygen regulator to use.ī. Nearly 100% The purpose of the pin-indexing system for compressed gas cylinders is to:Ī. What percentage of oxygen are you delivering?ĭ. You are performing bag-mask ventilations with oxygen connected and set at a flow rate of 15 L/min. remove her dentures, resume ventilations, and assess for adequate chest rise. attempt to replace her dentures so that they fit tightly and resume ventilations. leave her dentures in place and increase the rate and volume of your ventilations.ĭ. leave her dentures in place, but carefully monitor her for an airway obstruction.Ĭ. remove her dentures, resume ventilations, and assess for adequate chest rise.ī. When you reassess the patency of her airway, you note that her dentures are now loose, although your ventilations are still producing adequate chest rise. Adequate chest rise is present with each ventilation, and the patient's oxygen saturation reads 96%. She has dentures, which are tight fitting. 104, 40 You are ventilating an apneic woman with a bag-mask device. 5,600 mL The partial pressure of oxygen in the alveoli is _ mm Hg the partial pressure of carbon dioxide in the alveoli is _ mm Hg.ĭ. What is the alveolar minute volume of a patient with a tidal volume of 500 mL, a dead space volume of 150 mL, and a respiratory rate of 16 breaths/min?ĭ. hypoxia due to prolonged suction attempts. vomiting from stimulating the anterior airway.ĭ. clogging of the catheter with thick secretions.Ĭ. hypoxia due to prolonged suction attempts.ī. The MOST significant complication associated with oropharyngeal suctioning is:Ī. increasing the amount of delivered tidal volume. ensuring the appropriate airway position. ventilating the patient at the appropriate rate.ĭ. increasing the amount of delivered tidal volume.Ĭ. All of the following will help minimize the risk of gastric distention when ventilating an apneic patient with a bag-mask device, EXCEPT:ī. is a passive process caused by increased intrathoracic pressure. occurs when the diaphragm lowers and expels air from the lungs. is an active process caused by decreased intrathoracic pressure.ĭ. is a passive process caused by increased intrathoracic pressure.Ĭ. requires muscular effort to effectively expel air from the lungs.ī.
