1. In which situation does bradycardia require treatment?
Answer: Hypotension
2. Which intervention is most appropriate for the treatment of a patient inasystole?
Answer: Epinephrine
3. You arrive on the scene with the code team. High-quality CPR is in progress.An AED has

meets initial criteria for fibrinolytic therapy, and a CT scan of the brain si ordered. Which best
describes the guidelines for antiplatelet andfibrinolytic therapy?
Answer: Hold aspirin for at least 24 hours if rtPA is administered

defribillation shocks, epinephrine 1 mg IV twice, and an initial dose of amiodarone 300mg
IV. The patient is intubated. Which best describethe recommended second does of amiodarone
for this patient?

to nitrate administration?
Answer: Use of a phosphodiestrase inhibitorwithin the previous 24 hours
17. A 57-year-old woman has palpitation, chest discomfort, and tachycardia. The monitor
shows a regular wide-QRS at a rate of 180/min. She becomes diaphoretic, and her blood
pressure is 80/60 mm HG/ Which action do you takenext?
Answer: Perform electrical cardioversion
18. A patient with STEMI has ongoing chest discomfort. Heparin 4000 units IVbolus and a
heparin infusion of 1000 units per hour are being administered. The patient did not take aspirin
because he has a history of gastritis, with wastreated 5 years ago. What is your next action?
Answer: Give aspirin 160-325 mg to chew
, 19. You are caring for a 66-year-old man with a history of a large intracerebralhemorrhage 2
months ago. He is being evaluated for another acute stroke. The CT scan is negative for
hemorrhage. The patient is receiving oxygen via
nasal cannula at 2L/min, and an IV has been established. His blood pressure is 180/100mm
Hg. Which drug do you anticipate giving to this patient?
Answer: Aspirin
20. A patient is in pulseless ventricular tachycardia. Two shocks and 1 dose of epinephrine have
been given. Which drug should be given next?
Answer: Amiodarone300mg

Answer: 10 seconds
22. Your patient is a 56-year-old woman with a history of type 2 diabetes who reports feeling
dizzy. She is pale and diaphoretic. Her blood pressure is80/66mm Hg. The cardiac monitor
documents the rhythm shown here. She is receiving oxygen at 4L/min by nasal cannula, and
