West Coast EMT Block #2 Exam Accurate 100%

A 60-year-old man is found to be unresponsive, pulseless, and apneic. You should: - ANSWER B. begin CPR until an AED is available. Basic life support (BLS) is defined as: - ANSWER B. noninvasive emergency care that is used to treat conditions such as airway obstruction, respiratory arrest, and cardiac arrest. Between each chest compression, you should __________. - ANSWER B. allow full chest recoil Complications associated with chest compressions include all of the following, EXCEPT: - ANSWER B. gastric distention. CPR is in progress on a pregnant woman. Shortly after manually displacing her uterus to the left, return of spontaneous circulation occurs. Which of the following would MOST likely explain this? - ANSWER D. Pressure was relieved from her aorta and vena cava, which improved chest compression effectiveness. CPR retraining is the MOST effective when it: - ANSWER C. involves hands-on practice. CPR should be initiated when: - ANSWER D. a valid living will is unavailable. CPR will NOT be effective if the patient is: - ANSWER B. prone. Gastric distention will MOST likely occur: - ANSWER e. if you ventilate a patient too quickly. If an object is visible in the unconscious patient's airway, you should __________. - ANSWER C. remove it In most cases, cardiopulmonary arrest in infants and children is caused by: - ANSWER C. respiratory arrest. Several attempts to adequately open a trauma patient's airway with the jaw-thrust maneuver have been unsuccessful. You should: - ANSWER D. carefully perform the head tilt-chin lift maneuver. Signs of a sudden severe upper airway obstruction include all of the following, EXCEPT: - ANSWER D. forceful coughing. The impedance threshold device (ITD) may improve circulation during active compression-decompression CPR by: - ANSWER A. limiting the amount of air that enters the lungs during the recoil phase between chest compressions, which results in negative intrathoracic pressure and improved cardiac filling. What is the correct compression-to-ventilation ratio for adult CPR? - ANSWER A. 30:2 When performing CPR on a child, you should compress the chest: - ANSWER B. with one or two hands. While rescuer one is finishing his or her fifth cycle of 30 compressions, rescuer two should: - ANSWER D. move to the opposite side of the patient's chest.
