Airway, Ventilation & Respiration Study Center > Interactive Exam Prep > Airway, Ventilation & Respiration Step 1 of 5 20% A responsive 18 month-old female swallowed a marble and is cyanotic. You should:* perform CPR administer oxygen via pediatric NRB perform back blows and chest thrusts deliver abdominal thrusts While evaluating a 68 year old male patient complaining of an acute onset of shortness of breath, you note his pulse oximetry reading to be 92%. The patient presents in the tripod position with rhonchi on auscultation of the right chest. You should: * administer oxygen via cannula to achieve a saturation of 97% or above. provide oxygen by non-rebreather mask for as long as the patient complains of dyspnea. administer oxygen by cannula beginning at 2 lpm titrated to patient relief. withhold oxygen due to the patient’s probable COPD history. You arrive at a hotel to find a 27-year-old female unresponsive and breathing shallowly at a rate of 8/min. Your partner notes that the patient’s pupils are 2mm and sluggishly reactive to light. You should* determine the history of the present illness administer naloxone via nasal atomization administer oxygen at 15 lpm via non-rebreather mask assist the patient’s ventilations with a bag-mask device While ventilating an unresponsive 34-year-old male, you notice increased resistance during ventilations. You should:* increase the force of ventilations reposition the airway switch to a different bag-mask device slow ventilations to allow more time for the lungs to expand and relax The portion of the brain that is responsible for the control of ventilation is the* pons cerebellum medulla oblongata Pre-frontal cortex
