Which one of the following statements about the AED and its use in the treatment of cardiac arrest is true?
A) AEDs have simplified the treatment of cardiac arrest to the point where the EMT does not have to be worried about inappropriately shocking a patient.
B) Research has shown that the first shock delivered by an AED is often faster than the first shock delivered by a manual defibrillator.
C) To use an AED, the EMT must be able to identify some basic cardiac arrest heart rhythms so that he or she can tell the AED to shock or not shock the patient.
D) The AED is advantageous in that it will determine if a patient is in cardiac arrest and whether or not to shock.
Question 2
You have been called to a residence for a 63-year-old female with a history of COPD who is short of breath. The patient is moderately dyspneic with the following vital signs: pulse 124, respirations 20, blood pressure 162/56, and SpO2 at 86. She is using an oxygen concentrator set at 5 lpm. What is your best course of action?
A) Attach a nonrebreather to the oxygen concentrator and increase the liter flow to 12.
B) Continue oxygen administration with the concentrator and transport the patient.
C) Remove the oxygen concentrator and administer high-concentration oxygen to the patient.
D) Administer medical oxygen from your cylinder at the same rate as the concentrator.
