1. Which type of atrioventricular block best describes this rhythm? ✔✔C) Second-degree type II
2. Your patient is in cardiac arrest and has been intubated. To assess CPR quality, which should
you do? ✔✔A) Monitor the patient's PETCO2
3. Which facility is the most appropriate EMS destination for a patient with sudden cardiac who
achieved return of spontaneous circulation in the field? ✔✔D) Coronary reperfusion-capable
medical center
4. Which of the following signs is a likely indicator of cardiac arrest in an unresponsive patient?
✔✔C) Agonal gasps
5. Which type of atrioventricular block best describes this rhythm? ✔✔B) Second-degree
atrioventricular block type I
6. To properly ventilate a patient with a perfusing rhythm, how often do you squeeze the bag?
✔✔B) Once every 5 to 6 seconds.
7. In addition to clinical assessment, which is the most reliable method to confirm and monitor
correct placement of an endotracheal tube? ✔✔C) Continuous waveform capnography
8. You are caring for a patient with a suspected stroke whose symptoms started 2 hours ago.
The CT scan was normal, with no signs of hemorrhage. The patient does not have any
contraindications to fibrinolytic therapy. Which treatment is the best for this patient? ✔✔B)
Start fibrinolytic therapy as soon as possible.
9. Which best describes this rhythm? ✔✔D) Third-degree atrioventricular block.
10. What is the recommended range from which a temperature should be selected and
maintained constantly to achieve targeted temperature management after cardiac arrest?
✔✔C) 32 to 36 Degrees Celsius
11. Which is the recommended first intravenous dose of amiodarone for a patient with
refractory ventricular fibrillation? ✔✔D) 300 mg
, 12. What is the primary of a medical emergency team or rapid response team? ✔✔B)
Improving patient outcomes by identifying and treating early clinical deterioration.
13. What is the recommended next step after a defibrillation attempt? ✔✔D) Resume CPR,
starting with chest compressions
14. EMS providers are treating a patient with suspected stroke. According to the Adult
Suspected Stroke Algorithm, which critical action performed by the EMS team will expedite this
patient's care on arrival and reduce the time to treatment? ✔✔A) Alert the hospital.
15. A responder is caring for a patient with a history of congestive heart failure. The patient is
experiencing shortness of breath, a blood pressure of 68/50 mmHg, and a heart rate of
190/min. The patient's lead II ECG is displayed here. Which best characterizes this patient's
rhythm? ✔✔D) Unstable supraventricular tachycardia
16. Your rescue team arrives to find a 59-year-old man lying on the kitchen floor. You
determine that he is unresponsive. Which is the next step in your assessment and management
of this patient? ✔✔B) Check the patient's breathing and pulse.
17. Which best describes the length of time it should take to perform a pulse check during the
BLS assessment? ✔✔B) 5 to 10 seconds
18. You instruct a team member to give 1 mg Atropine IV. Which is the best example of closed-
loop communication? ✔✔C) I'll draw up 1 mg of Atropine.
19. What is an effect of excessive ventilation? ✔✔A) Decreased cardiac output.
20. If a team member is about to make a mistake during a resuscitation attempt, which best
describes the action that the team leader or other team members should take? ✔✔C) Address
the team members immediately.
21. Which best describes this rhythm? ✔✔A) Monomorphic ventricular tachycardia.
22. For STEMI patient, which best describes the recommended maximum goal time for
emergency department door-to-balloon inflation time for percutaneous coronary intervention?
✔✔D) 90 minutes.
23. Which is the maximum interval you should allow for an interruption in chest compressions?
✔✔A) 10 seconds.
