EMT - Ch9 - Airway Management

At a flow rate of 6L/min, a nasal cannula can deliver an approximate oxygen concentration of up to: a. 24% b. 35% c. 44% d. 52%

44%

An oxygen cylinder should be taken out of service and refilled when the pressure inside it is less than: a. 200 psi b. 500 psi c. 1000 psi d. 1500 psi

A 23 year old male experienced severe head trauma after his motorcycle collided with an oncoming truck. He is unconscious, has rapid and shallow breathing, and has copious bloody secretions in his mouth. How should you manage his airway? a. suction his oropharynx with a rigid catheter until all secretions are removed b. insert NPA and provide suction and assisted ventilations c. alternate 15 seconds of oral suctioning with 2 minutes of assisted ventilation d. provide continuous ventilations with a bag mask device to minimize hypoxia

alternate 15 seconds of oral suctioning with 2 minutes of assisted ventialation

The NPA is MOST beneficial because it: a. can effectively stabilize fractured nasal bones if it is inserted properly b. is generally well tolerated in conscious patients with an intact gag reflex c. effectively maintains the airway of a patient in cardiopulmonary arrest d. can maintain a patent airway in a semiconscious patient with a gag reflex

can maintain a patent airway in a semiconscious patient with a gag reflex

A 37 year old male has an apparent foreign body airway obstruction. He is conscious and alert and is coughing forcefully. His skin is pink, warm, and moist. The MOST appropriate treatment for this patient includes: a. a series of back blows and chest thrusts b. finger sweeps to remove obstruction c. performing a series of abdominal thrusts d. encouraging him to cough and transporting

encouraging him to cough and transporting

You are dispatched to a residence where a middle aged man was found unconscious in his front yard. There are no witnesses who can tell you what happened. You find him in a prone position; his eyes are closed and he is not moving. Your FIRST action should be to: a. palpate for the presence of a carotid pulse b. log roll him as a unit to a supine position c. assess the rate and quality of a his breathing d. open his airway with a jaw thrust maneuver

log roll him as a unit to a supine position

A 71 year old male is semiconscious following a sudden, sever headache. There is vomitus on his face and his respirations are shallow and slow. The EMT must immediately: a. insert a NPA b. perform oropharyngeal suctioning c. apply oxygen via a nonrebreathing mask d. assist the patients ventilations with a bag mask device

perform oropharyngeal suctioning

A 19 year old female is found lying unconscious by her roommate. Your primary assessment reveals that her breathing is inadequate. As you insert an OPA, she begins to gag violently. You should: a. continue to insert airway as you suction her oropharynx b. remove the airway and be prepared to suction her oropharynx c. insert the airway no further but leave it in place as a bite block d. selest a smaller OPA and attempt to insert it

remove the airway and be prepared to suction her oropharynx

While eating dinner, your partner suddenly grabs his throat and has a panicked look on his face. He has a weak cough, faint inspiratory stridor, and cyanosis around the lips. You should: a. encourage him to cough as forcefully as he can b. deliver up to five back blows and reassess him c. place him in a supine position and open his airway d. stand behind him and administer abdominal thrusts

stand behind him and administer abdominal thrusts

What is the MOST common cause of airway obstruction in an unconscious patient? a. vomitus b. the tongue c. blood clots d. aspirated fluids

tongue
