ACLS WRITTEN EXAM 1
You find an unresponsive pt. who is not breathing. After activating the emergency response system, you determine
there is no pulse. What is your next action? Correct Ans:- Start chest compressions of at least 100 per 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?
Correct Ans:- Obtaining a 12 lead ECG.
What is the preferred method of access for epi administration during cardiac arrest in most pts?
Correct Ans:- Peripheral IV
An AED does not promptly analyze a rythm. What is your next step?
Correct Ans:- 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 Ans:- 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 Ans:- Resume compressions
What is a common but sometimes fatal mistake in cardiac arrest manage- ment? Correct Ans:- Prolonged
interruptions in chest compressions.\
Which action is a componant of high-quality chest comressions?
Correct Ans:- Allowing complete chest recoil
Which action increases the chance of successful conversion of ventricular fibrillation?
Correct Ans:- Providing quality compressions immediately before a defibrillation attempt.
Which situation BEST describes pulseless electrical activity?
Correct Ans:- Sinus ry thm without a pulse
What is the BEST strategy for performing high-quality CPR on a patient with an advanced airway in place?
Correct Ans:- 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 Ans:- Chest compressions may not be effective.
The use of quantitative capnography in intubated patients
Correct Ans:- 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 Ans:- Consider terminating resuscitive efforts after consulting medical control.
Which is a safe and effective practice within the defibrillation sequence?-
Correct Ans:- 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 Ans:- Begin chest compressions.
What is an advantage of using hands-free defibrillation pads instead of defibrillation paddles?
, Correct Ans:- Hands-free pads allow for a more rapid defibrillation.
What action is recommended to help minimize interruptions in chest compressions during CPR?
Correct Ans:- Continue CPR while charging the defibrillator.
Which action is included in the BLS survey? Correct Ans:- Early defibrillation
Which drug and dose are recommended for the management of a patient in refractory ventricular fibrillation?
Correct Ans:- Amioderone 300mg
What is the appropriate interval for an interruption in chest compres- sions?
Correct Ans:- 10 seconds or less
Which of the following is a sign of effective CPR?
Correct Ans:- PETCO2 e10 mm Hg
What is the primary purpose of a medical emergency team (MET) or rapid response team (RRT)? Correct Ans:-
Identifying and treating early clinical deterioration.
Which action improves the quality of chest compressions delivered dur- ing a resuscitation attempt?
Correct Ans:- Switch providers about every 2 minutes or every 5 compression cycles.
What is the appropriate ventilation strategy for an adult in respiratory arrest with a pulse rate of 80/min?
Correct Ans:- 1 breath every 5-6 seconds
A patient presents to the emergency department with new onset of dizziness and fatigue. On examination, the
patient's heart rate is 35/min, the blood pressure is 70/50 mm Hg, the respiratory rate is 22 breaths/min, and the
oxygen saturation is 95%. What is the appropriate first medication?
Correct Ans:- Atropine 0.5mg
A patient with dizziness and shortness of breath with a sinus bradycardia of 40/min. The initial atropine dose was
ineffective, and your monitor/de- fibrillator is not equipped with a transcutaneous pacemaker. What is the appropriate
dose of dopamine for this patient?
Correct Ans:- 2 to 10 mcg/kg per minute
A patient has sudden onset of dizziness. The patient's heart rate is 180/min, blood pressure is 110/70 mm Hg,
respiratory rate is 18 breaths/min, and pulse oximetry reading is 98% on room air. The lead II ECG is shown below
Correct Ans:- Correct Ans:- Vagal maneuver.
A monitored patient in the ICU developed a sudden onset of narrow-com- plex tachycardia at a rate of 220/min. The
patient's blood pressure is 128/58 mm Hg, the PETCO2 is 38 mm Hg, and the pulse oximetry reading is 98%. There
is vascular access at the left internal jugular vein, and the patient has not been given any vasoactive drugs. A 12-
lead ECG confirms a supraven- tricular tachycardia with no evidence of ischemia or infarction. The heart rate has
not responded to vagal maneuvers. What is the next recommended intervention?
Correct Ans:- Adenosine 6mg IV push
You are receiving a radio report from an EMS team en route with a patient who may be having an acute stroke. The
hospital CT scanner is not working at this time. What should you do in this situation?
Correct Ans:- Divert the patient to a hospital 15 minutes away with CT capabilities.
Choose an appropriate indication to stop or withhold resuscitative efforts.
Correct Ans:- Evidence of rigor mortis.
A 49-year-old woman arrives in the emergency department with persis- tent epigastric pain. She had been taking
oral antacids for the past 6 hours because she thought she had heartburn. The initial blood pressure is 118/72 mm
Hg, the heart rate is 92/min and regular, the nonlabored respiratory rate is 14 breaths/min, and the pulse oximetry
reading is 96%. Which is the most appropriate intervention to perform next? Correct Ans:- Obtain a 12 lead ECG.
A patient in respiratory failure becomes apneic but continues to have a strong pulse. The heart rate is dropping
rapidly and now shows a sinus
bradycardia at a rate of 30/min. What intervention has the highest priority?-
Correct Ans:- Simple airway manuevers and assisted ventilations.
