SOLUTIONS RATED A+
✔✔You are evaluating a 48-year-old man with crushing substernal chest pain. The
patient is pale, diaphoretic, cool to the touch, and slow to respond to your questions.
The blood pressure is 58/32 mm Hg, the heart rate is 190/min, the respiratory rate is 18
breaths/min, and the pulse oximeter is unable to obtain a reading because there is no
radial pulse. The lead II ECG displays a regular wide-complex tachycardia. What
intervention should you perform next? - ✔✔Synchronized cardioversion
✔✔What is the initial priority for an unconscious patient with any tachycardia on the
monitor? - ✔✔Determine whether pulses are present.
✔✔Which rhythm requires synchronized cardioversion? - ✔✔Unstable supraventricular
tachycardia
✔✔What is the recommended second dose of adenosine for patients in refractory but
stable narrow-complex tachycardia? - ✔✔12mg
✔✔What is the usual post-cardiac arrest target range for PETCO2 when ventilating a
patient who achieves return of spontaneous circulation (ROSC)? - ✔✔35-40mm Hg
✔✔Which condition is a contraindication to therapeutic hypothermia during the post-
cardiac arrest period for patients who achieve return of spontaneous circulation ROSC?
- ✔✔Responding to verbal commands
✔✔What is the potential danger of using ties that pass circumferentially around the
patient's neck when securing an advanced airway? - ✔✔Obstruction of venous return
from the brain
✔✔What is the most reliable method of confirming and monitoring correct placement of
an endotracheal tube? - ✔✔Continuous waveform capnography
✔✔hat is the recommended IV fluid (normal saline or Ringer's lactate) bolus dose for a
patient who achieves ROSC but is hypotensive during the post-cardiac arrest period? -
✔✔1 to 2 Liters
✔✔What is the minimum systolic blood pressure one should attempt to achieve with
fluid, inotropic, or vasopressor administration in a hypotensive post-cardiac arrest
patient who achieves ROSC? - ✔✔90mm Hg
✔✔What is the first treatment priority for a patient who achieves ROSC? -
✔✔Optimizing ventilation and oxygenation.
, ✔✔What should be done to minimize interruptions in chest compressions during CPR? -
✔✔Continue CPR while the defibrillator is charging.
✔✔Which condition is an indication to stop or withhold resuscitative efforts? - ✔✔Safety
threat to providers
✔✔After verifying the absence of a pulse, you initiate CPR with adequate bag-mask
ventilation. The patient's lead II ECG appears below. What is your next action? - ✔✔IV
or IO access
✔✔After verifying unresponsiveness and abnormal breathing, you activate the
emergency response team. What is your next action? - ✔✔Check for a pulse.
✔✔What is the recommendation on the use of cricoid pressure to prevent aspiration
during cardiac arrest? - ✔✔Not recommended for routine use
✔✔What survival advantages does CPR provide to a patient in ventricular fibrillation? -
✔✔Produces a small amount of blood flow to the heart
✔✔What is the recommended compression rate for performing CPR? - ✔✔At least 100
per minute
✔✔EMS personnel arrive to find a patient in cardiac arrest. Bystanders are performing
CPR. After attaching a cardiac monitor, the responder observes the following rhythm
strip. What is the most important early intervention? - ✔✔defibrillation
✔✔A patient remains in ventricular fibrillation despite 1 shock and 2 minutes of
continuous CPR. The next intervention is to - ✔✔administer a second shock.
✔✔What is the recommended next step after a defibrillation attempt? - ✔✔Begin CPR,
starting with chest compressions.
✔✔Which of the following is the recommended first choice for establishing intravenous
access during the attempted resuscitation of a patient in cardiac arrest? -
✔✔Antecubital vein
✔✔Which finding is a sign of ineffective CPR? - ✔✔PETCO2 <10 mm Hg
✔✔How often should the team leader switch chest compressors during a resuscitation
attempt? - ✔✔. Every 2 minutes
