Case Study Questions

1. Biphasic defibrillators typically deliver a fixed lower delivered energy than the older conventional units. (200, 300, 360 joules). If an older defibrillator is used, what energy should be used for each shock, assuming that 3 shocks will be necessary?

   (200, 200, 360) (200, 300, 360) (360, 360, 360) none of the above

2. In the case of incessant reinduction, (the VF is treatable, but rapid reverts) which of the following drugs can be used in an attempt to prevent the recurrence of the arrhythmia?

   lidocaine amiodarone procainamide all of the above

3. When providing CPR as a single-rescuer, emergency ventilation:

   is not necessary should be done instead of chest compressions should be done at a rate of 20-40 breaths per minute all of the above

4. Which of the following constitute elements of quality CPR?

   minimum 2 inch compression depth allow complete chest recoil after each compression minimize interruptions to chest compressions all of the above

5. Pulse checks should be performed:

   every 30 seconds during CPR every 2 minutes during CPR every 10 minutes during CPR none of the above

6. The proper dose of epinephrine when administered IV during CPR is:

   10 ml of 1:1,000 10 ml of 1:10,000 1.0 ml of 1:10,000 100 ml of 1:1,000

7. Which of the following should be routinely given to patients with acute coronary syndromes?

   aspirin nitroglycerin morphine (if needed) all of the above

8. In the monitored patient developing ventricular fibrillation, what should occur first?

   2 minutes of quality CPR defibrillation the administration of lidocaine prior to the first shock none of the above

9. When using an automated external defibrillator:

   there is often no ECG monitor to see the patient's rhythm the AED will advise you when to shock the patient it is essential not to touch the lead wires while the unit is "analyzing" the patient's ECG all of the above

10. If the event (i.e. unstable ventricular tachycardia) is witnessed, should CPR be administered for several minutes prior to shock?

    true false
