You are evaluating a 58-year-old man with chest pain. The blood pressure is 92/50 mm Hg, the heart rate is 92/min, the nonlabored respiratory rate is 14 breaths/min, and the pulse oximetry reading is 97%. What assessment step is most important now? correct answer Obtaining a 12 lead ECG.

What is the preferred method of access for epi administration during cardiac arrest in most pts? correct answer Peripheral IV

An AED does not promptly analyze a rythm. What is your next step? correct answer Begin chest compressions.

You have completed 2 minutes of CPR. The ECG monitor displays the lead II rhythm below, and the patient has no pulse. Another member of your team resumes chest compressions, and an IV is in place. What management step is your next priority? correct answer Administer 1mg of epinephrine

During a pause in CPR, you see this lead II ECG rhythm on the monitor. The patient has no pulse. What is the next action? correct answer Resume compressions

What is a common but sometimes fatal mistake in cardiac arrest management? correct answer Prolonged interruptions in chest compressions.

Which action is a componant of high-quality chest comressions? correct answer Allowing complete chest recoil

Which action increases the chance of successful conversion of ventricular fibrillation? correct answer Providing quality compressions immediately before a defibrillation attempt.

Which situation BEST describes pulseless electrical activity? correct answer Sinus rythm without a pulse

What is the BEST strategy for performing high-quality CPR on a patient with an advanced airway in place? correct answer Provide continuous chest compressions without pauses and 10 ventilations per minute.

Three minutes after witnessing a cardiac arrest, one member of your team inserts an endotracheal tube while another performs continuous chest compressions. During subsequent ventilation, you notice the presence of a waveform on the capnography screen and a PETCO2 level of 8 mm Hg. What is the significance of this finding? correct answer Chest compressions may not be effective.

The use of quantitative capnography in intubated patients correct answer allows for monitoring of CPR quality.

For the past 25 minutes, an EMS crew has attempted resuscitation of a patient who originally presented in ventricular fibrillation. After the first shock, the ECG screen displayed asystole, which has persisted despite 2 doses of epinephrine, a fluid bolus, and high-quality CPR. What is your next treatment? correct answer Consider terminating resuscitive efforts after consulting medical control.

Which is a safe and effective practice within the defibrillation sequence? correct answer Be sure oxygen is not blowing over the patient's chest during the shock.

During your assessment, your patient suddenly loses consciousness. After calling for help and determining that the patient is not breathing, you are unsure whether the patient has a pulse. What is your next action? correct answer Begin chest compressions.

What is an advantage of using hands-free defibrillation pads instead of defibrillation paddles? correct answer Hands-free pads allow for a more rapid defibrillation.
