You are dispatched to an unconscious hemodialysis patient. On arrival to the dialysis clinic, the patient is unresponsive, apneic, and pulseless. You secure the ABCs, begin ventilation, and initiate chest compressions. However, the patient's cardiac arrest rhythm is continuously unresponsive to defibrillations with your AED. The best approach is to:
A) begin transporting and contact an ALS intercept. The patient's dysrhythmia may be related to kidney failure. B) continue defibrillating as the monitor recommends. The myocardium becomes increasingly responsive to successive defibrillations. C) call online medical control to terminate the code. The probability of survival is too low to continue resuscitation efforts. D) run a "no-electricity" code in which compressions and ventilation are continued. No additional defibrillations are necessary.
A patient uses a home ventilator connected to his tracheostomy tube to breathe. Which of the following is the correct procedure to use when moving this patient to the ambulance?
A) Ventilate the patient's tracheostomy tube via a connected bag-valve mask at a normal rate and volume while the patient is disconnected from the ventilator. B) Do nothing; there is no need to ventilate the patient between the house and the ambulance. C) Ventilate the patient's nose and mouth with a bag-valve mask at a normal rate and volume while the patient is disconnected from the ventilator. D) Ventilate the patient with mouth-to-mask ventilations at a normal rate and volume while the patient is disconnected from the ventilator.
