Oropharynx, larynx, trachea, carina, bronchioles Which of these statements is most correct regarding the difference between respiratio n and ventilation? a. Respiration describes the exchange of O2 and CO2, while ventilation describes the movement of air that carries them into and out of the body b. Respiration and ventilation are similar terms that both describe normal and healthy breat hing in the living organism c. Ventilation describes the absorption of O2 into the cells, while ventilation is the excretion of CO2 from the cells d.

When carbon dioxide accumulates within the body b. When carbon dioxide is excreted too rapidly from the lungs c. If inadequate amounts of O2 are available to the cells d. If the respiratory rate decreases to less th an 12 breaths per minute The EMT recognizes a late sign of hypoxia in a patient in a coma when he observes: a. Cyanosis in the fingers b. Complaint of a headache c. Restlessness and agitation d. Elevation in blood pressure You have been called for a patient who has overdosed on drugs and alcohol. The patient is responsive to painful stimuli, has shallow respirations and is breathing at a rate of 8 times per minute, but exhib its no cyanosis. What is the priority treatment? a. Inadequate respirations; start positive pressure ventilation with supplemental oxygen b. Inadequate breathing; administer oxygen at 15 lpm through a nonrebreather face mask c. Adequate breathing; adminis ter oxygen at 15 lpm through a nonrebreather face mask d. Adequate breathing; initiate positive pressure ventilation with supplemental oxygen Which of these patients would benefit from the head -tilt, chin -lift manual airway maneuver as opposed to any other initial airway management technique? a. An 85 -year-old female who hit her head on a tree limb and is now responsive to painful stimuli b. A 45 -year-old female who is alert and vomiting blood c. A 39 -year-old male who just had a seizur e and has snoring respirations d. A 67 -year-old female who fell down a flight of stairs and is unresponsive EMT Page 3 A 2-year-old boy who just seized must have his airway opened.

If necessary, the head should be only slightly extended d. The head must be hyperextended You arrive at a residence for a male patient who is unresponsive. As you enter the room, you observe an obese man lying on a recliner. His eyes are closed, and he has gurgling respirations. While your partner is quickly performing a primary assessment, you should immediately prepare to: a. Suction the airway b. Administer high -concentration oxygen c. Insert an oropharyngeal airway d. Auscultate breath sounds While you are transporting a patient with altered mental status, he suddenly vomits partially digested food along with large blood clots. The vomitus is too big for the rigid suction catheter. The EMT should immediately place the patient on his side and: a. Use a soft suction catheter b. Encourage the patient to cough c. Perform a finger sweep d. Administer abdominal thrusts You must suction frothy secretions from the mouth and pharynx of a 31 -year-old male patient whose respiration rat e is 4 breaths/min. Which process to do so is most appropriate given the patient's condition? a. Suction for no more than 15 seconds at a time, followed by 2 minutes of positive pressure ventilation b. Forego suctioning and continue to provide positive pr essure ventilation, as frothy secretions rarely complicate the airway
