EMT PRACTICE QUEST QUESTIONS WITH CORRECT ANSWERS GRADED A+

1. Upon insertion of an oropharyngeal airway (OPA), the tip of the device should be positioned in what anatomical space? - Laryngopharynx fully supports the tongue by lifting the base off the posterior pharynx; 2. The administration of a beta2-specific drug to a patient with respiratory distress is done to effect a change to what portion of the respiratory tree? - Bronchioles; beta2-specific drugs will relax smooth muscle which wraps the bronchioles of the lungs and allow for better airflow 3. Which of the following statements from the patient would BEST indicate severe difficulty in breathing? - "I...can't....breathe" cannot speak in full sentences = not breathing adequately and will need oxygen and possible PPV support 4. Which of the following patients is about to lose total airway patency, thereby requiring immediate intervention by the EMT? - a sixty-eight-year-old male seizing with sonorous sounds heard with each breath AKA SNORING = partial upper airway occlusion 5. Upon assessment of the patient's airway, you note significant gurgling with each breath. What would be the next appropriate airway intervention the EMT should perform to eliminate this finding? - Oropharyngeal suctioning 6. You are managing a female patient who has been in an auto accident and is now unresponsive. As you manage her airway, which of the following interventions would you likely NOT employ? - application of a head-tilt, chin-lift maneuver could do: OPA, upper airway suctioning, and modified jaw-thrust maneuver can be applied without cervical manipulation 7. When sizing an OPA for insertion in a forty-eight-year-old male, which sizing technique is most appropriate? - You should measure the OPA from the center of the teeth to the angle of the jaw or front the corner of the mouth to the earlobe 8. During your initial airway management, your patient needs suctioning for prolonged vomiting. How long should you provide this? - normally 10 seconds but as this patient has prolonged vomiting -> for as long as needed to remove vomitus - aspirating vomit can have detrimental effects 9. The mechanical process of respiration (ventilation) occurs in two phases. Which phase sees a negative pressure inside the thorax to make the ventilation process work? - inhalation exhalation = positive pressure 10. A patient with severe asthma is having trouble breathing and adequately ventilating. What portion of normal tidal volume is this patient most likely experiencing the greatest disturbance in? - Alveolar space ventilation the balance of tidal volume is alveolar ventilation; when breathing is impaired - alveolar space ventilation suffers because dead space volume does not change 11. A patient with a change in his ventilation status secondary to a severe chest wall injury will likely display what specific early finding indicative of poor alveolar ventilation? - Absent breath sounds in the bases of the lungs 12. A patient is found with a respiratory rate of 8 per minute, absent basal breath sounds, a pulse ox reading of 83 percent, and cyanotic lips and fingernails. This patient is in immediate need of what intervention? - Ventilation 13. Which of the following findings would still be present in a patient suffering from mild respiratory distress? - Full speech patterns; can still maintain adequate ventilation respiratory distress = normal pulse ox readings and mental status; no cyanosis altered mental status, cyanosis, and low pulse ox = respiratory failure and arrest 14. You are managing a patient who was in a fight and was struck in the head with a large pipe. You find the patient to be unresponsive, apneic, bradycardic, bleeding from the head, and bleeding into the airway from oral trauma. what should be the initial action? - suction in the airway after suction - PPV with high-flow oxygen; then immobilization following treatment of life threats 15. Which of the following chemical indications would first appear to indicate that the patient is being adequately ventilated with a BVM? - The patient has breath sounds in all lung fields can see chest wall movement even though not being adequately ventilated 16. If the EMT wishes to deliver the highest concentration of oxygen possible to the patient with spontaneous breathing, what oxygenation adjunct should she use? - Nonrebreather mask - will allow inhalation of 100% O2 17. You are preparing to treat a patient with CPAP for respiratory distress. Upon assessment, however, you observe the following findings. WHich of these would serve as a contraindication for the uses of CPAP? - Systolic blood pressure of 88mmHg (should not be use on patients with bp
