1. As you attempt to ventilate your apneic patient the first breath is unsuccessful. Your next step would be to: A: reposition the head. B: assess the brachial pulse. C: assess the carotid pulse. D: begin chest compressions. 2. The most common airway obstruction in unresponsive patients or patients with altered mental status is caused by: A: dentures. B: vomitus. C: broken teeth. D: the tongue. 3. When ventilating a patient it is important to avoid gastric distention. The best way to avoid gastric distention or making it worse if it develops is: A: Deliver breaths that are enough to just cause the chest to rise B: Deliver forceful breaths that override the epiglottis C: Deliver quick breaths that don't cause the chest to rise D: Use a basic airway adjunct to occlude the esophagus 4. What is the ventilation rate when performing rescue breathing for a child? A: 10 - 12 breaths per minute B: 12 - 20 breaths per minute C: 15 - 30 breaths per minute D: 25 - 50 breaths per minute 5. You have a child with a suspected airway obstruction who has become unresponsive. You should next: A: perform abdominal thrusts. B: open the airway and attempt to ventilate. C: perform back blows. D: ventilate the patient. 6. Which of the following is a sign of inadequate breathing, in infants and children? A: Regular chest movements B: Nasal flaring C: Equal expansion of both sides of the chest when patient inhales D: Typical skin coloration 7. Which of the following patients should have their airway opened using a jaw thrust maneuver? A: A 35-year-old woman with diabetes found unresponsive in the driver's seat of her vehicle in the parking lot of her apartment complex B: a patient found unresponsive in her bed in a nursing home C: A 50-year-old woman who choked on a piece of food while dining in a restaurant and now has a clear airway D: A 25-year-old man who is still unresponsive after being struck by a vehicle 8. Your patient, in whom you have inserted an oropharyngeal airway, is beginning to regain consciousness and develop a gag reflex. Which of the following is the proper way of managing this situation? A: Pull the airway out slightly to keep it away from the back of the throat. B: Use gentle manual pressure to keep the patient from expelling the airway. C: Remove the airway quickly. D: Spray a topical anesthetic into the throat to prevent the gag reflex from being stimulated. 9. Which of the following is true concerning the procedure for inserting a nasopharyngeal airway? A: The bevel should be turned toward the nasal septum. B: If a water-soluble lubricant is not available, a silicon spray can be substituted. C: It can only be placed in the right nostril. D: The length of the device is not as important as it is with oropharyngeal airways. 10. Which of the following is the correct method of suctioning? A: Suction intermittently, both while inserting and withdrawing the suction tip or catheter. B: Insert the catheter or tip to the desired depth prior to applying suction. C: Begin suctioning as you insert the suction tip or catheter into the mouth. D: Suction continuously, both while inserting and withdrawing the suction tip or catheter. 11. Which of the following should be kept in mind when assessing and managing the airway of a pediatric patient? A: The trachea is easily obstructed by swelling. B: The tongue is not as likely to obstruct the airway as in an adult. C: Due to their short necks, pediatric patients require a greater degree of hyperextension to open the airway than do adults. D: Gastric distention is unlikely. 12. The normal stimulus to breathe is stimulated by the chemoreceptors that measure the concentration of what two gases? A: Increasing hydrogen and high carbon monoxide B: High carbon monoxide and decreasing oxygen C: Increasing hydrogen and high carbon dioxide D: Increasing carbon dioxide and low oxygen 13. Which of the following patients does NOT require the administration of supplemental oxygen? A: A 60-year-old woman with a history of chronic obstructive pulmonary disease (COPD) who can speak two or three words at a time without a breath B: A 6-year-old male with a history of asthma whose breath sounds are silent and who is drowsy C: A 31-year-old male who is unresponsive due to an overdose of narcotics D: A 24-year-old woman who is breathing 28 times per minute after being in an argument with her husband 14. What signs and symptoms would indicate inadequate breathing in a patient? A: Increased effort to breathe, increased depth of respiration, pink dry skin, normal mental status B: Rapid breathing, pale skin, and a normal mental status C: Decreased depth of respiration, decreased rate of breathing, hot clammy skin, normal mental status D: Increased effort to breathe, cyanosis, cool clammy skin, altered mental status 15. Which of the following describes why fast ventilation inhibits adequate respiration? A: The lungs may not have the time to fill and exchange gas. B: The rate causes turbulence in the trachea that increases the friction and decreases the amount of air movement. C: It is due to the delay in the movement of the intercostal muscles and the pleural space. D: The rate does not decrease inhaled volume; it actually increases it. 16. Your 68-year-old patient is suffering from chronic obstructive pulmonary disease; this condition can cause gas exchange interruption by what process? A: It is caused by a long-term disease process that blocks the blood flow to the alveoli due to arteriolosclerosis interrupting gas exchange. B: The larynx is constricted by the abundance of thick secretions that reduce the airflow. C: It limits the alveoli's capability to exchange oxygen and carbon dioxide because the alveoli itself is occluded. D: The process of inspiration and expiration has grown sluggish due to the advanced age of the patient and the deterioration of the lung tissue. 17. You have arrived at the scene of a call for a "man down." As you enter the residence you note that your patient is a male in his mid-60s who is unresponsive. He is perspiring profusely, has cyanosis of his ears and lips, and has rapid, shallow respirations. Which of the following should you do first? A: Place the patient on a NRB at 15 lpm. B: Obtain the patient's medical history. C: Listen to the patient's lung sounds. D: Assist ventilations with a bag-valve mask and supplemental oxygen. 18. Your patient is a motorcyclist who was ejected from his vehicle after striking a guard rail. The patient is unresponsive to painful stimuli and is breathing six to eight times per minute. Which of the following should you do first? A: Use a bag-valve mask with supplemental oxygen. B: Perform a rapid trauma assessment. C: Apply a cervical collar. D: Apply a nonrebreather mask with an oxygen flow rate of 15 lpm. 19. Your patient is a 4-year-old male who was struck by a vehicle and is now unresponsive with an obvious head injury. As you are ventilating him with a bag-valve-mask device, you detect increasing resistance to ventilation. Which of the following should you do? A: Reassess airway and suction if necessary. B: Stop ventilations for 1 to 2 minutes to allow trapped air to escape from the lungs. C: Roll patient into recovery position to ensure that the airway is open. D: Switch to a flow-restricted oxygen-powered ventilation device. 20. You are transporting a 44-year-old female with chest pain and sudden respiratory distress. She is agitated, anxious, and refuses to have a nonrebreather mask applied. Which of the following is the best option? A: Use a nasal cannula instead. B: Have her breathe into a paper bag to control her hyperventilation. C: Do not make further attempts to administer oxygen as it will only agitate the patient further. D: Consult with medical control about restraining the patient. Quiz Score: out of 20
