You arrive on the scene to find CPR in progress. Nursing staff report the patient was recovering from a pulmonary embolism and suddenly collapsed. Two shocks have been delivered, and an IV has been initiated. What do you administer now? A. atropine 0.5 mg IV |
B. epinephrine 1 mg IV |
|
A 45-year-old woman with a history of palpitations develops light-headedness and palpitations. She has received adenosine 6 mg IV for the rhythm shown here (SVT), without conversion of the rhythm. She is n9ow extremely apprehensive. Her blood pressure is 128/70 mm Hg. What is the next appropriate intervention? A. administer adenosine 12 mg IV |
A. administer adenosine 12 mg IV |
|
What is the recommended depth of chest compression for an adult victim? A. at least 1.5 inches |
B. at least 2 inches |
|
A patient’s 12-lead ECG is transmitted by the paramedics and shows a STEMI. When the patient arrives in the emergency department, the rhythm shown here (ST elevation) is seen on the cardiac monitor. The patient has resolution of moderate (5/10) chest pain after 3 doses of sublingual nitroglycerin. Blood pressure is 104/70 mm Hg. Which intervention is most important in reducing this patient’s in-hospital and 30-day mortality rate? A. application of transcutaneous pacemaker |
D. reperfusion therapy |
|
A patient has been resuscitated from cardiac arrest. During post-ROSC treatment, the patient becomes unresponsive, with the rhythm shown here (polymorphic ventricular tachycardia). which action is indicated next? A. give an immediate unsynchronized high-energy shock |
A. give an immediate unsynchronized high-energy shock (defibrillation dose) |
|
A patient becomes unresponsive. You are uncertain if a faint pulse is present. The rhythm shown here is seen on the cardiac monitor. An IV is in place. Which action do you take next? A. begin transcutaneous pacing |
B. start high-quality CPR |
|
Your patient is not responsive and is not breathing. You can palpate a carotid pulse. Which action do you take next? A. apply an AED |
D. start rescue breathing |
|
After initiation of CPR and 1 shock for ventricular fibrillation, this rhythm (ventricular fibrillation) is present on the next rhythm check. A second shock is given, and chest compressions are resumed immediately. An IV is in place, and no drugs have been given. Bag-mask ventilations are producing visible chest rise. What is your next intervention? A. administer 3 sequential (stacked) shocks at 360 J |
C. give epinephrine 1 mg IV / IO |
|
What is the recommended compression rate for high-quality CPR? A. 50 to 60 compressions per minute |
D. 100 to 120 compressions per minute |
|
A 35-year-old woman presents with a chief complaint of palpitations. She has no chest discomfort, shortness of breath, or light-headedness. Her blood pressure is 120/78 mm Hg. Which intervention is indicated first? A. adenosine 3 mg IV bolus |
D. vagal maneuvers |
|
Which action should you take immediately after providing an AED shock? A. check the pulse rate |
C. resume chest compressions |
|
Which action is likely to cause air to enter the victim’s stomach (gastric inflation) during bag-mask ventilation? A. giving breaths over 1 second |
B. ventilation too quickly |
|
What is the maximum interval for pausing chest compressions? A. 10 seconds |
A. 10 seconds |
|
How often should you switch chest compressors to avoid fatigue? A. about every 2 minutes |
A. about every 2 minutes |
|
Your patient is a 56-year-old woman with a history of type 2 diabetes who reports feeling dizzy. She is pale ad diaphoretic. Her blood pressure is 80/60 mm Hg. The cardiac monitor documents the rhythm shown here (sinus bradycardia). she is receiving oxygen at 4 L/min by nasal cannula, and an IV has been established. What so you administer next? A. atropine 0.5 mg IV |
A. atropine 0.5 mg IV |
|
How does complete chest recoil contribute to effective CPR? A. allows maximum blood return to the heart |
A. allows maximum blood return to the heart |
|
You are the code team leader and arrive to find a patient with CPR in progress. On the next rhythm check, you see the rhythm shown here (looks like normal sinus rhythm). Team members tell you that the patient was well but reported chest discomfort and then collapsed. She has no pulse or respirations. Bag-mask ventilations are producing visible chest rise, and IO access has been established. which intervention would be your next action? A. atropine 1 mg |
C. epinephrine 1 mg |
|
What action minimizes the risk of air entering the victim’s stomach during bag-mask ventilation? A. ventilating until you see the chest rise |
A. ventilating until you see the chest rise |
|
A patient was in refractory ventricular fibrillation. A third shock has just been administered. Your team looks to you for instructions. What is your next action? A. check the carotid pulse |
D. resume high-quality chest compressions |
|
You are providing bag-mask ventilations to a patient in respiratory arrest. How often should you provide ventilations? A. about every 5-6 seconds |
A. about every 5-6 seconds |
