PMED CHAPTER 15 EXAM REVIEW 2022 A young woman experienced massive facial trauma after being ejected from her car when it struck a tree. She is semiconscious, has blood draining from her mouth, and has poor respiratory effort. The MOST appropriate initial airway management for this patient involves: - ANS-alternating suctioning her oropharynx for 15 seconds and assisting her ventilations for 2 minutes until you can definitively secure her airway. CPAP is NOT appropriate for patients with: - ANS-slow, shallow respiratory effort A 50-year-old woman presents with acute respiratory distress while eating. Upon your arrival, you note that she is conscious, coughing, and wheezing between coughs. Further assessment reveals that her skin is pink and moist. In addition to transporting her to the hospital, you should: - ANS-encourage her to cough and closely monitor her condition. Surfactant is: - ANS-a phospholipid compound that decreases surface tension on the alveolar walls. All of the following are complications associated with orotracheal intubation, EXCEPT: - ANS-necrosis of the nasal mucosa. When ventilating a patient with facial injuries, it is MOST important to: - ANS-be alert for changes in ventilation compliance Which of the following interventions is NOT appropriate when treating an unresponsive patient whose airway is obstructed by a dental appliance? - ANSAbdominal thrusts Capnography is a reliable method for confirming proper ET tube placement because: - ANS-carbon dioxide is not present in the esophagus. After inserting an oropharyngeal airway in an unresponsive woman, the patient begins to gag. You should: - ANS-remove the airway and have suction ready. Asymmetric chest wall movement is characterized by: - ANS-one side of the chest moving less than the other. Indications for CPAP include: - ANS-acute pulmonary edema The function of the lower airway is to: - ANS-exchange oxygen and carbon dioxide. Using the DOPE mnemonic, which of the following interventions would you MOST likely have to perform if you suspect "O" as the cause of acute deterioration in the intubated child? - ANS-Tracheobronchial suctioning The anterior portion of the palate is formed by the: - ANS-maxilla and palatine bones When a patient's respirations are too rapid and too shallow: - ANS-inhaled air may only reach the anatomic dead space before being exhaled. When ventilating a patient with a bag-mask device, you note increased compliance. This means that: - ANS-air can be forced into the lungs with relative ease. The pulse oximeter would be LEAST useful when: - ANS-determining if a patient should receive oxygen. A 36-year-old man experienced significant burns to his face, head, and chest following an incident with a barbeque pit. Your assessment of his airway reveals severe swelling. After administering medications to sedate and paralyze the patient, you are unable to intubate him. Furthermore, bag-mask ventilations are producing minimal chest rise. The quickest way to secure a patent airway in this patient is to: - ANS-perform a needle cricothyrotomy. When two paramedics are ventilating an apneic patient with a bag-mask device, the paramedic not squeezing the bag should: - ANS-maintain an adequate mask-to-face seal. You are transporting an intubated patient and note that the digital capnometry reading has quickly fallen below 30 mm Hg. You should: - ANS-take immediate measures to confirm proper placement of the ET tube. Biot respirations are characterized by: - ANS-an irregular pattern of breathing with intermittent periods of apnea. You should be MOST suspicious of tube misplacement following an open cricothyrotomy if: - ANS-a crackling sensation is noted when palpating the neck. A 66-year-old woman is found to be unresponsive and apneic. Her carotid pulse is weak and rapid. When ventilating this patient, you should deliver: - ANS-each breath over 1 second at a rate of 10 to 12 breaths/min. The BEST way to be certain that the ET tube has passed through the vocal cords is to: - ANS-visualize the tube passing between the vocal cords. When administering CPAP therapy to a patient, it is important to remember that: - ANS-the increased intrathoracic pressure caused by CPAP can result in hypotension...
