Several attempts to adequately open a trauma patient's airway with the jaw-thrust maneuver have been unsuccessful. You should: A. tilt the head back while lifting up on the patient's neck. B. carefully perform the head tilt-chin lift maneuver. C. suction the airway and reattempt the jaw-thrust maneuver. D. try opening the airway by lifting up on the chin.

C. acute cyanosis. D. inability to speak. [Ans: - A. forceful coughing. The impedance threshold device (ITD) may improve circulation during active compression-decompression CPR by: A. maximizing the amount of air in the lungs following chest recoil, which hyperinflates the lungs and forces more blood from the ventricle during each compression. B. drawing all of the air out of the lungs in between chest compressions, which causes positive intrathoracic pressure and a reduction of blood return to the right side of the heart. C. maintaining increased intrathoracic pressure during the downward stroke of each chest compression, which forces more blood from both of the ventricles. D. limiting the amount of air that enters the lungs during the recoil phase between chest compressions, which results in negative intrathoracic pressure and improved cardiac filling. [Ans: - D. limiting the amount of air that enters the lungs during the recoil phase between chest compressions, which results in negative intrathoracic pressure and improved cardiac filling. What is the correct compression-to-ventilation ratio for adult CPR? A. 30:2 B. 30:1 C. 3:2 D. 5:1 [Ans: - A. 30:2 When performing CPR on a child, you should compress the chest: A. until a radial pulse is felt. B. to a depth of 1 to 2 inches. C. 80 to 100 times per minute. D. with one or two hands. [Ans: - D. with one or two hands While rescuer one is finishing his or her fifth cycle of 30 compressions, rescuer two should: A. assess for a carotid pulse for 15 seconds. B. give two breaths and prepare to start compressions. C. move to the opposite side of the patient's chest. D. suction the patient's mouth and give two more ventilations. [Ans: - C. move to the opposite side of the patient's chest. Without practice, your CPR skills will __________. Select one: A. improve over time B. deteriorate over time C. become part of your muscle memory D. come back automatically when needed [Ans: - B. deteriorate over time Your conscious patient has a mild partial airway obstruction. You should: A. encourage the patient to cough. B. administer back blows. C. perform abdominal thrusts. D. place the patient supine. [Ans: - A. encourage the patient to cough. Your partner is performing one-rescuer CPR on a middle-aged woman in cardiac arrest. When you apply the AED pads, you note that she has a medication patch over the same area where one of the AED pads will be placed. You should: A. continue CPR until you can determine the name of the medication contained in the patch. B. move the patch to another area of the patient's chest and then properly apply the AED pads. C. remove the medication patch, wipe away any medication residue, and apply the AED pads. D. apply the AED pad at least 1 inch away from the medication patch to avoid skin burns. [Ans: - C. remove the medication patch, wipe away any medication residue, and apply the AED pads. 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 a nasopharyngeal airway and provide suction and assisted ventilations. C. Provide continuous ventilations with a bag-valve mask to minimize hypoxia. D. Alternate 15 seconds of oral suctioning with 2 minutes of assisted ventilation. [Ans: - D. Alternate 15 seconds of oral suctioning with 2 minutes of assisted ventilation. A 51-year-old female presents with a sudden onset of difficulty breathing. She is conscious and alert and able to speak in complete sentences. Her respirations are 22 breaths/min and regular. You should: A. administer oxygen via a nonrebreathing mask. B. insert a nasal airway in case her mental status decreases. C. perform a secondary assessment and then begin treatment. D. assist her ventilations with a bag-valve mask. [Ans: - A. administer oxygen via a nonrebreathing mask. A nasopharyngeal airway is inserted: Select one: A. with the bevel pointing downward if inserted into the left nare. B. into the smaller nostril with the tip following the roof of the nose. C. with the bevel facing the septum if inserted into the right nare. D. into the larger nostril with the tip pointing away from the septum. [Ans: - C. with the bevel facing the septum if inserted into the right nare A ventilation/perfusion (V/Q ratio) mismatch occurs when: A. a disruption in blood flow inhibits the exchange of oxygen and carbon dioxide in the lungs, even though the alveoli are filled with fresh oxygen. B. ventilation is compromised, resulting in the accumulation of carbon dioxide in the bloodstream, alveoli, and the tissues and cells of the body. C. ventilation is inadequate due to a traumatic injury or medical condition, which results in an impairment in pulmonary gas exchange. D. a traumatic injury or medical condition impairs the body's ability to effectively bring oxygen into the lungs and remove carbon dioxide from the body. [Ans: - A. a disruption in blood flow inhibits the exchange of oxygen and carbon dioxide in the lungs, even though the alveoli are filled with fresh oxygen. An oxygen cylinder should be taken out of service and refilled when the pressure inside it is less than: A. 1,000 psi. B. 200 psi. C. 500 psi. D. 1,500 psi. [Ans: - C. 500 psi.
