EMT FINAL EXAM 1 EMT FINAL EXAM (ALL 100 QUESTIONS ANSWERED 100% CORRECT) 2023 -2024 Which of these statements is most correct regarding the difference between respiration and ventilation? a. Ventilation describes the exchange of gases at the cellular level, while respiration describes the same process between the lungs and the external environment b. Ventilation describes the absorption of O2 into the cells, while ventilation is the excreti on of CO2 from the cells c. Respiration describes the exchange of O2 and CO2, while ventilation describes the movement of air that carries them into and out of the body d. Respiration and ventilation are similar terms that both describe normal and healthy breathing in the living organism When does hypoxia occur? a. If inadequate amounts of O2 are available to the cells b. When carbon dioxide accumulates within the body c. If the respiratory rate decreases to less than 12 breaths per min ute d. When carbon dioxide is excreted too rapidly from the lungs You have been called for a patient who has overdosed on drugs and alcohol. The patient is responsive to painful stimuli, has shallow respirations and is breathing at a rate of 8 times per minute, but exhibits no cyanosis. What is the priority treatment? a. Inadequate respirations; start positive pressure ventilation with supplemental oxygen b. Adequate breathing; administer oxygen at 15 lpm through a nonrebreather face mask c. Inadequate breathing; administer oxygen at 15 lpm through a nonrebreather face mask d. Adequate breathing; initiate positive pressure ventilation with supplemental oxygen EMT FINAL EXAM 2 A 2-year-old boy who just seized must have his airway opene d. When performing the head -tilt, chin -lift airway maneuver, the EMT must remember: a. The head must be flexed forward b. A towel roll should be placed under the head c. If necessary, the head should be only slightly extended d. The head must be hyperexte nded You must suction frothy secretions from the mouth and pharynx of a 31 -year-old male patient whose respiration rate is 4 breaths/min. Which process to do so is most appropriate given the patient's condition? a. Use a soft -tip catheter and suction for no more than 30 seconds before providing additional oxygen with a nonrebreather face mask b. Suction for no more than 15 seconds at a time, followed by 2 minutes of positive pressure ventilation c. Place the patie nt into a side -lying position and alternate 30 seconds of suctioning and ventilation d. Forego suctioning and continue to provide positive pressure ventilation, as frothy secretions rarely complicate the airway Which of these is a corre ct statement about the ventilation of a nonbreathing patient through a stoma? a. A nasal airway should be inserted into the stoma prior to any attempt at ventilating the patient b. The EMT should ventilate through the stoma with a child -sized face mask attached to a bag -valve mask c. Mouth -to-stoma ventilation is an easy and safe procedure to perform on a nonbreathing patient d. A head -tilt, chin -lift maneuver or jaw -thrust airway maneuver is still needed to open the airway You are chec king the D oxygen tank in the ambulance and note that the reading on the pressure regulator is 1000 psi. You should recognize that the tank is: EMT FINAL EXAM 3 a. Almost empty b. Leaking c. Overfilled d. Half full A patient with a stoma and tracheosto my tube is responsive to painful stimuli. He has shallow respirations and is breathing at a rate of 6 times per minute. He has cyanosis of the fingertips and a weak, rapid radial pulse. Which strategy should be used in providing respiratory care to this pa tient? a. Use a continuous positive airway pressure device over the stoma b. Attach the bag -valve device directly to the tracheostomy tube c. Place a tracheostomy mask over the tube and administer high -concentration oxygen d. Remove the tracheostomy tube, place a child -size mask on the bag -valve device, and ventilate the patient through the stoma A patient who inhaled superheated steam in an industrial fire is most likely to exhibit which abnormal upper airway noise? a. Stridor b. Snoring c. Gurgling d. Wheezing Your paramedic partner has applied continuous positive airway pressure (CPAP) to a patient in respiratory distress from congestive heart failure (CHF). As an EMT, you realize that this treatment should benefit the patient by: a. Collapsing portions of the diaphragm b. Causing the diaphragm to relax during inspiration c. Removing air from the lungs during exhalation d. Displacing fluid in the alveoli back into the bloodstream
