the active, muscular part of breathing is called: correct answer: inhalation A 22-year-old man crashed his motorcycle into a tree. He is found approximately 20 feet away from his bike and is responsive to pain only. He is not wearing a helmet. You are unable to effectively open his airway using the jaw-thrust maneuver. What should you do? correct answer: Carefully tilt his head back and lift up on his chin. what is the function of pulmonary surfactant? correct answer: it lubricates the alveolar walls and allows them to expand and recoil. which of the following devices is contraindicated in patients with blunt thoracic trauma? correct answer: Oxygen-powered ventilator. You are performing abdominal thrusts on a 19-year-old male with a severe airway obstruction when he becomes unresponsive. After lowering him to the ground and placing him in a supine position, you should: correct answer: begin CPR, starting with chest compressions. As you begin ventilating an unresponsive apneic man, you hear gurgling in his upper airway. Your MOST immediate action should be to correct answer: quickly turn the patient onto his side so secretions can drain Which of the following injuries or conditions should be managed FIRST correct answer: Bleeding within the oral cavity You are assessing a 66-year-old man who has emphysema and complains of worsened shortness of breath. He is confused, has a heart rate of 120 beats/min, and an oxygen saturation of 89%. Which of the following assessment findings should concern you the MOST? correct answer: Confusion An inaccurate pulse oximetry reading may be caused by: correct answer: severe peripheral vasoconstriction. A patient who is breathing with reduced tidal volume would MOST likely have correct answer: shallow respirations During your assessment of an unresponsive adult female, you determine that she is apneic. You should: correct answer: assess for a carotid pulse. In which of the following situations would you MOST likely encounter agonal gasps? correct answer: Shortly after becoming unresponsive and pulseless A patient overdosed on heroin and is unresponsive. He is cyanotic; he has slow, shallow breathing; and his oxygen saturation is 80%. The primary cause of this patient's condition is inadequate correct answer: ventilation which of the following statements regarding the head tilt-chin lift maneuver is correct? correct answer: it should be used in conjunction with an appropriate airway adjunct. Hypoxia is defined as: correct answer: inadequate oxygen to the body's cells and tissues. Which of the following signs or symptoms is indicative of cerebral hypoxia correct answer: decreased level of consciousness Clinically, reduced tidal volume would MOST likely present with respirations that are: correct answer: shallow To obtain the most reliable assessment of a patient's tidal volume, you should correct answer: look at the rise of the chest A patient overdosed on several drugs and is unresponsive with shallow breathing and facial cyanosis. As you continue your assessment, the patient suddenly vomits. You should: correct answer: turn the patient onto his side A properly placed oropharyngeal airway correct answer: keeps the tongue off of the posterior pharynx. An elderly woman with COPD is semiconscious with labored breathing. Her face is cyanotic, her pulse is rapid and weak, and her oxygen saturation is 75%. You should correct answer: ventilate her with a bag-valve-mask device and high-flow oxygen. Shallow breathing is an indication of: correct answer: decreased tidal volume. During your initial attempt to ventilate an unresponsive apneic patient, you meet resistance and do not see the patient's chest rise. You should correct answer: reposition the head and reattempt to ventilate If an adult patient presents with a respiratory rate of 26 breaths/min, your initial action should be to correct answer: Evaluate his mental status and the depth of his respirations To ensure you deliver the highest concentration of oxygen with a nonrebreathing mask, you should: correct answer: make sure the reservoir bag is pre-inflated The lower airway begins at the correct answer: larynx Which of the following yields the lowest minute volume? correct answer: Respiratory rate of 14 breaths/min; tidal volume of 300 mL.
