A 19-year-old female is found unconscious by her roommate. Your primary assessment reveals that her breathing is inadequate. As you insert an oropharyngeal airway, she begins to gag violently. You should: A. continue to insert the airway as you suction her oropharynx. B. insert the airway no further but leave it in place as a bite block. C. remove the airway and be prepared to suction her oropharynx. D. select a smaller oropharyngeal airway and attempt to insert it. - ANSWER C. remove the airway and be prepared to suction her oropharynx A man was found unresponsive in his bed at home. There is no evidence of injury and the patient's medical history is not known. The patient's face is cyanotic, yet the pulse oximeter reads 98%. Which of the following would MOST likely explain this? A. Severe pulmonary edema B. Carbon monoxide poisoning C. Increased body temperature D. His extremities are cold - ANSWER B. Carbon monoxide poisoning A patient who is suspected of being hypoxic and is breathing adequately should be given supplemental oxygen with a: A. nasal cannula. B. nonrebreathing mask. C. mouth-to-mask device. D. bag-valve mask. - ANSWER B. nonrebreathing mask During your assessment of a patient with respiratory distress, you hear wheezing when listening to breath sounds. This indicates: A. fluid in the alveoli. B. swelling of the upper airway. C. secretions in the airway. D. a lower airway obstruction. - ANSWER D. a lower airway obstruction How does CPAP improve oxygenation and ventilation in patients with certain respiratory problems? A. It decreases intrathoracic pressure, which allows more room for lung expansion. B. It forces the alveoli open and pushes oxygen across the alveolar membrane. C. It prevents alveolar collapse by pushing air into the lungs during inhalation. D. It pushes thick, infected pulmonary secretions into isolated areas of the lung. - ANSWER B. It forces the alveoli open and pushes oxygen across the alveolar membrane In which of the following patients would the head tilt-chin lift maneuver be the MOST appropriate method of opening the airway? A. A 50-year-old male who is unconscious following head trauma B. A 45-year-old male who is semiconscious after falling 20 feet C. A 24-year-old male who is found unconscious at the base of a tree D. A 37-year-old female who is found unconscious in her bed - ANSWER A 37-year- old female who is found unconscious in her bed Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called: A. agonal respirations. B. ataxic respirations. C. Cheyne-Stokes respirations. D. eupneic respirations. - ANSWER C. Cheyne-Stokes respirations The nasopharyngeal airway is MOST beneficial because it: A. is generally well tolerated in conscious patients with an intact gag reflex. B. can effectively stabilize fractured nasal bones if it is inserted properly. C. can maintain a patent airway in a semiconscious patient with a gag reflex. D. effectively maintains the airway of a patient in cardiopulmonary arrest. - ANSWER C. can maintain a patent airway in a semiconscious patient with a gag reflex The physical act of moving air into and out of the lungs is called: A. oxygenation. B. respiration. C. diffusion. D. ventilation. - ANSWER D. ventilation What occurs when a patient is breathing very rapidly and shallowly? A. The majority of tidal volume reaches the lungs and diffuses across the alveolar- capillary membrane. B. Air is forcefully drawn into the lungs due to the negative pressure created by the rapid respirations. C. Minute volume increases because of a marked increase in both tidal volume and respiratory rate. D. Air moves primarily in the anatomic dead space and does not participate in pulmonary gas exchange. - ANSWER D. Air moves primarily in the anatomic dead space and does not participate in pulmonary gas exchange When testing a mechanical suctioning unit, you should turn on the device, clamp the tubing, and ensure that it generates a vacuum pressure of more than: A. 300 mm Hg. B. 200 mm Hg. C. 400 mm Hg. D. 100 mm Hg. - ANSWER A. 300 mm Hg Which of the following is the MOST reliable indicator of adequately performed bag-valve mask ventilations in an apneic adult with a pulse? A. Adequate rise of the chest when squeezing the bag B. Consistently increasing heart rate C. Decreased compliance when squeezing the bag D. Twenty breaths/min being delivered to the adult - ANSWER A. Adequate rise of the chest when squeezing the bag Which of the following patients is breathing adequately? A. A conscious male with respirations of 18 breaths/min and reduced tidal volume B. A conscious female with facial cyanosis and rapid, shallow respirations C. A conscious male with respirations of 19 breaths/min and pink skin D. An unconscious 52-year-old female with snoring respirations and cool, pale skin - ANSWER C. A conscious male with respirations of 19 breaths/min and pink skin Which of the following patients should you place in the recovery position? A. A 24-year-old unconscious female who overdosed and has a reduced tidal volume B. A 19-year-old conscious male with a closed head injury and normal respirations C. A 40-year-old conscious female with a possible neck injury and regular respirations
