Your patient is a 4-year-old male who was struck by a vehicle and is now unresponsive with an obvious head injury. As you are ventilating him with a bag-valve-mask device, you detect increasing resistance to ventilation. Which of the following should you do?
1) Perform a head-tilt, chin-lift to ensure that the airway is open.
2) Stop ventilations for one to two minutes to allow trapped air to escape from the lungs.
3) Switch to a flow-restricted oxygen-powered ventilation device.
4) Reposition the Jaw thrust.

Back 7

4) Reposition the Jaw thrust.

Front 8

Your patient is a 55-year-old man with a history of chronic bronchitis. You have been called to his home today because of an increase in his level of respiratory distress. The patient is on 2 liters per minute of oxygen by nasal cannula at home. Your assessment reveals difficulty speaking due to shortness of breath, leaning forward to breathe, a productive cough, and a respiratory rate of 32 per minute. Which of the following is true concerning the best course of action for this patient?
1) You should increase the patient's oxygen flow rate until his respiratory rate decreases and then resume oxygen administration at 2 liters per minute.
2) You should increase the patient's oxygen flow rate to deliver adequate amounts of oxygen to his tissues. If his respiratory rate decreases, you can assist him with a bag-valve-mask device.
3) You should not increase the patient's oxygen flow rate because of his likely dependence on a hypoxic drive to stimulate breathing.
4) Because increased blood levels of carbon dioxide is the primary stimulus to breathe, you should encourage the patient to rebreathe his exhaled air from a paper bag.

Back 8

2) You should increase the patient's oxygen flow rate to deliver adequate amounts of oxygen to his tissues. If his respiratory rate decreases, you can assist him with a bag-valve-mask device.
