ACLS EP Chapter 6 Quiz

Select the best response from the answer choices following each question.

1. A 22-year-old man was just in a major motorcycle accident. There is a concern for a cervical spine injury as well as facial fractures. He is unconscious, but breath sounds are evident with continued chest rise. The jaw thrust maneuver has failed to open the airway. What is the best initial management of his airway at this time?

2. What is an associated physiological change from hyperventilation in the cardiac arrest patient receiving CPR?

3. Which of the following is the role of end-tidal carbon dioxide during resuscitation?

4. During resuscitation, until the provider knows the patient’s oxygen saturation, oxygen supplementation should be provided at what percent FiO₂?

5. Which one of the following physiologic measurements best aids the team in assessing the quality of CPR efforts?

6. A 56-year-old man is in cardiac arrest. As the patient’s oxygen saturation is persistently low and ventilation is inadequate, the decision is made to intubate. Following placement of the ET tube, waveform capnography along with auscultation and evaluation of chest rise is used to ensure correct tube placement. Following ROSC, the patient is stabilized and taken to get a chest X-ray to rule out a primary pulmonary condition. Continuous waveform capnography reveals this change?

What is the next step in management?
