1. While the EMT is inserting an oropharyngeal airway, the patient gags. The EMT should:

2. Which tip should you give a new EMT about artificially ventilating a patient with the bag- valve mask?

3. When providing an in-service program on ventilating the geriatric patient, you should emphasize which point in regard to a patient who has dentures?

4. A 52-year-old male patient with a brain tumor has gone into respiratory arrest, but still has a pulse and obtainable blood pressure. You assign the task of artificially ventilating the patient with the bag-valve mask to a new Emergency Medical Responder. How will you instruct him to ventilate the patient?

5. The EMT shows that he is correctly using the flow-restricted, oxygen-powered ventilation device when he:

6. Which of these sequences best describes the path that oxygen must travel to get into the cells of the body?

7. An elderly male patient who is short of breath is on home oxygen. He is wearing a nasal cannula connected to an oxygen tank with the flow regulator set to 3 liters per minute. As a knowledgeable EMT, you should recognize that the patient is getting approximately what percentage of oxygen with each breath?

8. The EMT would recognize that administering continuous positive airway pressure (CPAP) at a pressure that is too high can cause:

9. Which of these statements made by another crew member would cause you to disregard the use of continuous positive airway pressure (CPAP) for a patient?

10. A paramedic has asked you to place the patient on a nonrebreather mask at 15 liters per minute. To administer oxygen at this flow rate, you should:

11. Which configuration on the bag-valve mask (BVM) will enable the EMT to deliver the highest concentration of oxygen to the patient?

12. A patient complaining of shortness of breath and a history of asthma has the following vital signs: pulse, 96; respirations, 20 breaths/min; blood pressure, 132/86 mmHg; and SpO2, 92% on room air. Mild wheezing is noted bilaterally, and the patient states that she has run out of her rescue inhaler (albuterol). Regarding the patient's respiratory status, how should you initially administer oxygen?

13. In a healthy person, the primary stimulus to breathe is:

14. You are checking the D oxygen tank in the ambulance and note that the reading on the pressure regulator is 1000 psi. You should recognize that the tank is:

15. The EMT is properly applying continuous positive airway pressure (CPAP) when he:

16. When administering oxygen to a hypoxic patient with Alzheimer's disease, which of these findings would seemingly indicate that the patient's hypoxic status is improving?

17. You are assessing a patient with altered mental status. Which of these assessment findings contraindicates the use of the nonrebreather face mask?

18. A 2-year-old boy who just seized must have his airway opened. When performing the head- tilt, chin-lift airway maneuver, the EMT must remember:

19. You have arrived next to a patient who reportedly had a seizure. Assessment reveals him to be apneic with vomitus in the airway. He has a radial pulse, and his skin is cool and diaphoretic. What should you do immediately?

20. What is a benefit of using a humidification system when administering oxygen?

21. For which of these patient is placement of an oropharyngeal airway indicated?

22. Which action should you perform when attaching a therapy regulator to a new oxygen tank?

23. Proper positioning of the airway with the head-tilt, chin-lift maneuver during ventilation can help reduce gastric inflation by:

24. When using a therapy regulator, what can be readily observed by the EMT?

25. You have arrived on the scene of an assault in which several people were injured. You are directed to assist another crew with a patient who has been shot once. As you approach, you are told that the patient has slow and irregular breathing that is inadequate. You observe the patient being ventilated with a bag-valve mask while another EMT maintains her airway with the jaw- thrust maneuver. Based on your observation, where might you expect that this patient was shot?
