ACLS Exam PREP A/50
Questions with 100% Correct
Solutions/Updated
You find an unresponsive patient who is not breathing. After activating
the emergency response system, you determine that there is no pulse.
What is your next action? - -Start chest compressions at a rate of at
least 100/min.
-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? - -Obtaining a 12-
lead ECG
-What is the preferred method of access for epinephrine administration
during cardiac arrest in most patients? - -Peripheral intravenous
-An activated AED does not promptly analyze the rhythm. What is your
next action? - -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? (strip missing displays a 3rd
degree heart block) - -Administer 1 mg 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? (strip missing
displays tachycardic sinus rhythm) - -Resume chest compressions.
-What is a common but sometimes fatal mistake in cardiac arrest
management? - -Prolonged interruptions in chest compressions
-Which action is a component of high-quality chest compressions? - -
Allowing complete chest recoil
-Which action increases the chance of successful conversion of
ventricular fibrillation? - -Providing quality compressions immediately
before a defibrillation attempt
-Which situation BEST describes pulseless electrical activity? - -Sinus
rhythm without a pulse
, -What is the BEST strategy for performing high-quality CPR on a patient
with an advanced airway in place? - -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? - -Chest
compressions may not be effective
-The use of quantitative capnography in intubated patients - -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? - -Consider terminating resuscitative efforts after
consulting medical control.
-Which is a safe and effective practice within the defibrillation
sequence? - -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? - -Begin chest compressions.
-What is an advantage of using hands-free defibrillation pads instead of
defibrillation paddles? - -Hands-free pads allow for a more rapid
defibrillation.
-What action is recommended to help minimize interruptions in chest
compressions during CPR? - -Continue CPR while charging the
defibrillator.
-Which action is included in the BLS Survey? - -Early defibrillation
-Which drug and dose are recommended for the management of a
patient in refractory ventricular fibrillation? - -Amiodarone 300 mg
-What is the appropriate interval for an interruption in chest
compressions? - -10 seconds or less
-Which of the following is a sign of effective CPR? - -PETCO2 ≥10 mm
Hg
