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 approach is best for this patient? -
CORRECT ANSWER✔✔Give fibrinolytic therapy as soon as possible and consider endovascular
therapy
5. Which is the recommended next step after a defibrillation attempt? - CORRECT
ANSWER✔✔Resume CPR, starting with chest compressions
6. Which of the following signs is a likely indicator of cardiac arrest in an unresponsive patient? -
CORRECT ANSWER✔✔Agonal gasps
7. You are evaluating a 58-year-old man with chest discomfort. His blood pressure is 92/50 mm
Hg, his heart rate is 92/min, his nonlabored respiratory rate is 14 breaths per minute, and his
pulse oximetry reading is 97%. Which assessment step is most important now? - CORRECT
ANSWER✔✔Obtaining a 12-lead ECG
, 8. During post-cardiac arrest care, which is the recommended duration of targeted temperature
management after reaching the correct temperature range? - CORRECT ANSWER✔✔At least 24
hours
9. Which type of atrioventricular block best describes this rhythm? - CORRECT
ANSWER✔✔Second-degree atrioventricular block type I
10. 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? - CORRECT ANSWER✔✔Check the patient's breathing and pulse
Use this scenario to answer the next 6 questions: - CORRECT ANSWER✔✔A 45-year-old man
had coronary artery stents placed 2 days ago. Today, he is in severe distress and is reporting
"crushing" chest discomfort. He is pale, diaphoretic, and cool to the touch. His radial pulse is
very weak, blood pressure is 64/40 mm Hg, respiratory rate is 28 breaths per minute, and
oxygen saturation is 89% on room air. When applied, the cardiac monitor initially showed
ventricular tachycardia, which then quickly changed to ventricular fibrillation.
11. On the basis of this patient's initial presentation, which condition do you suspect led to the
cardiac arrest? - CORRECT ANSWER✔✔Acute coronary syndrome
12. In addition to defibrillation, which intervention should be performed immediately? -
CORRECT ANSWER✔✔Chest compressions
13. Despite 2 defibrillation attempts, the patient remains in ventricular fibrillation. Which drug
and dose should you administer first to this patient? - CORRECT ANSWER✔✔Epinephrine 1 mg
14. Despite the drug provided above and continued CPR, the patient remains in ventricular
fibrillation. Which other drug should be administered next? - CORRECT ANSWER✔✔Lidocaine 1
to 1.5 mg/kg
