team (RRT)? - ✔✔Identifying and treating early clinical deterioration.
✔✔Which action improves the quality of chest compressions delivered during a
resuscitation attempt? - ✔✔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? - ✔✔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? - ✔✔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/defibrillator is not equipped
with a transcutaneous pacemaker. What is the appropriate dose of dopamine for this
patient? - ✔✔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: - ✔✔Vagal manuever.
✔✔A monitored patient in the ICU developed a sudden onset of narrow-complex
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 supraventricular tachycardia with no evidence of ischemia or
infarction. The heart rate has not responded to vagal maneuvers. What is the next
recommended intervention? - ✔✔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? - ✔✔Divert the patient to a hospital 15 minutes away
with CT capabilities.
, ✔✔Choose an appropriate indication to stop or withhold resuscitative efforts. -
✔✔Evidence of rigor mortis.
✔✔A 49-year-old woman arrives in the emergency department with persistent 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? - ✔✔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? - ✔✔Simple airway manuevers and
assisted ventilations.
✔✔What is the appropriate procedure for endotracheal tube suctioning after the
appropriate catheter is selected? - ✔✔Suction during withdrawal but for no longer than
10 seconds.
✔✔While treating a patient with dizziness, a blood pressure of 68/30 mm Hg, and cool,
clammy skin, you see this lead II ECG rhythm:What is the first intervention ? -
✔✔Atropine 0.5mg
✔✔A 68-year-old woman experienced a sudden onset of right arm weakness. EMS
personnel measure a blood pressure of 140/90 mm Hg, a heart rate of 78/min, a
nonlabored respiratory rate of 14 breaths/min, and a pulse oximetry reading of 97%.
The lead II ECG displays sinus rhythm. What is the most appropriate action for the EMS
team to perform next? - ✔✔Cincinnati Prehospital Stroke Scale assessment
✔✔EMS is transporting a patient with a positive prehospital stroke assessment. Upon
arrival in the emergency department, the initial blood pressure is 138/78 mm Hg, the
pulse rate is 80/min, the respiratory rate is 12 breaths/min, and the pulse oximetry
reading is 95% on room air. The lead II ECG displays sinus rhythm. The blood glucose
level is within normal limits. What intervention should you perform next? - ✔✔Head CT
scan
✔✔What is the proper ventilation rate for a patient in cardiac arrest who has an
advanced airway in place? - ✔✔8-10 breaths per minute
✔✔A 62-year-old man in the emergency department says that his heart is beating fast.
He says he has no chest pain or shortness of breath. The blood pressure is 142/98 mm
Hg, the pulse is 200/min, the respiratory rate is 14 breaths/min, and pulse oximetry is
