A PLUS

A patient who is suspected of being hypoxic and is breathing adequately should be given supplemental oxygen with a: - SOLUTION Non-breathing mask The nasal cannula is MOST appropriately used in the prehospital setting: - SOLUTION when the patient cannont tolerate a nonbreathing mask The primary waste product of aerobic metabolism is: - SOLUTION carbon dioxide The Nasopharyngeal airway is MOST beneficial because it: - SOLUTION can maintain a patent airway in a semiconscious patient with a gag reflex The MOST significant complication association with oropharyngeal suctioning is: - SOLUTION hypoxia due to prolonged suction attempts. What is the alveolar minute volume of a patient with a tidal volume of 500 mL, a dead space volume of 150 mL, and a respiratory rate of 16 breaths/minute? - SOLUTION 5,600 mL You are ventilating an apneic woman with a bag-mask device. She has dentures, which are tight fitting. Adequate chest rise is present with each ventilation, and the patient's oxygen saturation reads 96%. When you reassess the patency of her airway, you note that her dentures are now loose, although your ventilations are still producing adequate chest rise. You should: - SOLUTION Remove her dentures, resume ventilations, and assess for adequate chest rise. Tidal volume is defined as the volume of air that: - SOLUTION moves into or out of the lungs in a single breath. 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

most. The MOST appropriate treatment for this patient includes: - SOLUTION encouraging him to cough and transporting. For which of the following conditions would the EMT most likely administer humidified oxygen? - SOLUTION Croup Inhalation occurs when the: - SOLUTION diaphragm and intercostal muscles contract and cause a decrease in intrathoracic pressure The MOSt serious complication associated with using a nasopharyngeal airway in a patient with trauma to the head or face is: - SOLUTION pentrating the cranium CPAP is indicated for patients who: - SOLUTION have pulmonary edema and can follow verbal commands Prior to applying a nonrebreathing mask to a patient, you must ensure that the: - SOLUTION reservoir bag is fully inflated. Which of the following is the MOST reliable indicator of adequately performed bag mask ventilations in an apneic adult with a pulse? - SOLUTION Adequate rise of the chest when squeezing the bag. You are ventilating a 40 year old uninjured man who is apneic but has a pulse. When your partner reassesses his blood pressure, she notes that he has decreased significantly from previous readings. You should: - SOLUTION reduce the rate or volume of the ventilations you are delivering. Which of the following patients MOST likely require insertion of an oropharyngeal airway? - SOLUTION A 40 year old unconscious patient with slow, shallow respirations. The actual exchange of oxygen and carbon dioxide occurs in the: - SOLUTION alveolar sacs. Without adequate oxygen, the body's cells - SOLUTION incompletely convert glucose into energy, and lactic acid accumulates in the blood.

As the single EMT managing an apneic patient's airway, the preferred initial method of providing ventilations is the: - SOLUTION mouth to mask technique with a one way valve. In which of the following patients would the head tilt-chin lift manuever be the MOST appropriate method of opening the airway? - SOLUTION A 37 year old female who is found unconscious in her bed. Which of the following statements regarding positive-pressure ventilation is correct? - SOLUTION With positive - pressure ventilation, more volume is required to have the same effects as normal breathing. Based on current guidelines, in which of the following situations should supplemental oxygen be administered? - SOLUTION exposure to carbon monoxide and an oxygen saturation of 94% A 23-year old male experienced severe head trauma after his motorcycle collided with an oncoming truck. He is unconscious, has agonal gasps, and has copious bloody secretions in his mouth. How should you manage his airway? - SOLUTION Alternate oropharyngeal suctioning and ventilation with a bag-mask device. To select the proper size oropharyngeal airway, you should measure from the: - SOLUTION corner of the mouth to the earlobe. You are ventilating a patient with a stoma; however, air is escaping from the mouth and nose. To prevent this, you should: - SOLUTION seal the mouth and nose. A 19-year old female is found unconscious by her roommate. Your primary assessment reveals that her breathing is inadequate. As you insert an oropharyngeal airway, she begins to gag violently. You should: - SOLUTION remove the airway and be prepared to suction her oropharynx. Central chemoreceptors located in the medulla provide feedback to increase the rate and depth of breathing when they sense: - SOLUTION slight increases in carbon dioxide or a decrease in the pH of the cerebrospinal fluid.

Which of the following would cause an increase in the amount of exhaled carbon dioxide? - SOLUTION Increased cardiac output Each cell of the body combines nutrients and oxygen and produces energy and waste products through a process called: - SOLUTION metabolism An oxygen cylinder should be taken out of service and refilled when the pressure inside it is less than: - SOLUTION 500 psi At a flow rate of 6 L/min, a nasal cannula can deliver an approximate oxygen concentration of up to: - SOLUTION 44% Gas exchange in the lungs is facilitated by: - SOLUTION adequate amounts of surfactant. High flow oxygen with a nasal cannula during the preoxygenation phase of endotracheal intubation is called: - SOLUTION apneic oxygenation Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called: - SOLUTION Cheyne- Stokes respirations Oxygen toxicity is a condition in which: - SOLUTION cellular tissue damage occurs from excessive oxygen levels in the blood. Structures of the lower airway include all of the following, except - SOLUTION the epiglottis The diaphragm is innervated by the ____ nerve, which allows it to contract
