WEST COAST EMT BLOCK 2 EXAM

The EMT should assess a patient's tidal volume by? A. observing for adequate chest rise B. assessing the facial area for cyanosis C. counting the patient's respiratory rate D. measuring the patient's oxygen saturation - A. Observing for adequate chest rise Tidal volume- the volume of air that is moved in or out of lungs by single breathobserved by adequate chest rise. If rise is shallow, tidal volume is likely reduced. In an otherwise healthy individual, the primary stimulus to breath is a(n): A. increased level of oxygen in the blood B. decreased level of oxygen in the blood C. increased level of carbon dioxide in blood D. decreased level of carbon dioxide in blood - C. increased level of carbon dioxide in blood Under control of the brain stem, rising levels of carbon dioxide in the arterial blood normally stimulate breathing in an otherwise healthy patient. Signs of adequate breathing in the adult include all of the following, EXCEPT: A. pink, warm, dry skin B. shallow chest rise C. symmetrical chest movement D. a respiratory rate of 16 breaths/min - B. shallow chest rise shallow chest rise= reduced tidal volumeDuring insertion of an oropharyngeal airway into an unconscious patient, she begins to vomit. The first thing you should do is: A. turn the patient on her side. B. remove the airway at once. C. suction the patient's mouth. D. use a smaller-sized oral airway. - A. turn the patient on their side allows vomit to drain In which of the following patients would a nasopharyngeal airway be contraindicated? A. a semiconscious patient with a gag reflex B. an unconscious patient with an intact gag reflex C. a patient who fell 20 feet and lander on their head D. an unconscious patient who gags when you insert an oral airway - C. a patient who fell 20 feet and lander on their head contraindication with patients with severe head or facial injuries You are delivering oxygen to a patient with a nasal cannula at 4L/min when he begins to complain of a burning sensation in his nose. You should: A. remove the nasal cannula B. apply a nonrebreathing masks C. attach oxygen humidifier D. increase the flow rate to 6 L/min - C. attach an oxygen humidifier administering "dry" oxygen especially over a prolonged period can results in drying of nasal membranesA patient is found unconscious after falling from a third floor window. His respirations are slow and irregular. You should: A. place him in the recovery position B. apply oxygen via a nonrebreathing mask C. suction his airway for up to 15 seconds D. assist his breathing with a bag-valve mask device - D. assist his breathing with a bag-valve mask device slow/irregular breaths= inadequate oxygen When ventilating an apneic adult with a simple barrier device, you should squeeze the bag: A. until its empty B. over a period of 2 seconds C. at a rate of 20 breaths/min D. until visible chest rise is noted - D. until visible chest rise is noted You and your partner are ventilating an apneic adult when you notice that is stomach is becoming distended. You should: A. suction his airy for up to 15 seconds B. reposition his head C. increase the rate and volume D. decreased ventilation rate but increase the volume - B. reposition his head gastric distention occurs when air enters the stomach You are managing a 62yr old who complains of crushing chest pain. Her BP is 84/64 with HR of 110. Medical control advises you to assist in her taking her prescribed nitroglycerin. You should:A. reassess the HR then assisted with nitro B. repeat the BP to DR and confirm order C. wait 10 mins, reassess BP, then give nitro D. administer the nitro and reassess BP - B. Repeat the BP to DR and confirm order Nitroglycerin is a vasodilator and lowers BP, contraindication in BP 100
