Fire department meters confirm dangerously high levels. He is alert and his vital signs are P 98, R 20, BP 120/80. His pulse oximetry reads 97% on room air. You should first*obtain a capnography reading.administer calcium chloride.administer high concentration oxygen.administer low concentration oxygen. A 35 year old male has overdosed on calcium channel blocker pills. He presents semiconscious and you note a very slow sinus bradycardia on the monitor. His vital signs are P 34, R 6, BP 70/40. You should first*administer calcium chloride.administer glucagon.begin chest compressions.initiate positive pressure ventilation. A 59 year old male has collapsed while watching a football game. He is unconscious. After assuring that the scene is safe, you should next*defibrillate at 200J.assess for a pulse.begin chest compressions.assess for breathing. A 14 year old male was thrown from an ATV at moderate speed. He is found unconscious with snoring respirations. You should first*open the airway with a head-tilt, chin-lift maneuver.attempt to suction the patient’s airway.elevate the patient’s head to a 30 degree angle.consider spinal precautions. A 9 year old male has been sick with a sore throat for three days. His mother called EMS today when she found him gasping and making a crowing sound while breathing. You find the patient unconscious and apneic. First responders attempted intubation but identified a large mass around the tonsils that interfered with passing the tube. Attempts at bag mask ventilation have been unsuccessful. You should next*administer racemic epinephrine.attempt intubation again.Initiate a surgical airway.insert a supraglottic airway.

A 65 year old female developed a rapid onset of aphasia and right-sided weakness. Over the next 30 minutes she has rapidly lost her mental status and is now unconscious. The patient has vomited twice and is unable to protect her airway. You should next*insert an endotracheal tube.obtain a prehospital stroke scale.insert a supraglottic airway.ventilate using a bag mask device. A 19 year old male is in severe respiratory distress. His family states he has been struggling all day but was resistant to calling EMS. They note a long history of asthma. The patient is confused, cyanotic and gasping for air.

You are attempting to face mask ventilate a morbidly obese patient who has taken a narcotic overdose. You are unable to obtain chest rise with your initial breath.

A 31 year old male has a large, open hole in his chest wall just above his right nipple. Which of the following would best describe why he would be unable to inflate his lungs on inhalation?*Rising intrapleural pressureInability to generate negative intrathoracic pressureDestruction of his diaphragmInability to generate positive intrathoracic pressure A 65 year old male with a history of coronary artery disease presents with a new onset of severe shortness of breath. He is breathing with severe distress and his respiratory rate is 60. When assessing waveform capnography you note very low amplitude waves and a numeric value of 10 mmHg. You should suspect*your capnograph is not functioning properly.a spontaneous pneumothorax.respiratory alkalosis.a pulmonary embolism. You have just intubated a 59 year old male. You identified the epiglottis and visualized the tube as it passed the vocal cords. After inflating the cuff of the tube, you should next*begin 10-12 ventilations per minute.confirm the tube with end-tidal capnography.confirm the presence of epigastric sounds.secure the tube using a commercial tube holder. A 77 year old male is being transported on a ventilator and suddenly develops signs of hypoxia including cyanosis and low pulse oximetry. You further note the new onset of JVD.
