TMC Kettering prep quiz questions and verified answers

A 7 year old child suspected of having epiglottitis would exhibit which of the following signs? - correct answers drooling hyperextended neck stridor A spontaneous breathing trial has been initiated for a 64-year-old, intubated, post-op patient. Oxygen is being administered by T-piece at an FIO2 of 0.50 via heated air-entrainment nebulizer at a flow of 12 L/min and a temperature of 37.0oC. The respiratory therapist notices that the aerosol mist disappears from the reservoir outlet during the patient's inspiration. The therapist should consider all the following EXCEPT. lengthening the reservoir tubing. adding an additional nebulizer. increasing the flow to 15 L/min. increasing the temperature to 39.0 C. - correct answers increasing the temperature to 39.0 C The respiratory therapist is reviewing a patient's chart prior to performing a bedside assessment to determine readiness for weaning from ventilatory assistance. The patient weighs 60 kg (132 lb). The therapist would expect the patient to be able to achieve a spontaneous tidal volume of? - correct answers 300 - 480 mL The physician informs the patient that the results of his polysomnogram indicate obstructive sleep apnea. Treatment for this disorder might include which? bronchial hygiene therapy. respiratory stimulants.. tracheostomy. negative pressure ventilation. - correct answers tracheostomy Which of the following would NOT be required to perform a nasal intubation? Magill forceps Stylet Laryngoscope Endotracheal tube - correct answers stylet A patient has just been intubated with a naso-tracheal tube and is being manually ventilated. As the respiratory therapist ventilates the patient, he notices that there is no chest movement, minimal breath sounds and air escaping from the mouth as the bag is squeezed. A chest x-ray has determined that the endotracheal tube is in the correct position. What is the most likely cause of this situation? The tube is in the esophagus. The patient has developed a tracheoesophageal fistula from the intubation process. The cuff ruptured during intubation. The cuff has herniated over the end of the tube. - correct answers The cuff ruptured during intubation. A patient is receiving 40% oxygen via a Venturi mask at 8 L/min. While performing oxygen rounds, the respiratory therapist notes that the flowmeter setting has been changed to 12 L/min. How would this change affect the accuracy of this device? - correct answers None: Fio2 would remain the same A patient recently underwent a thoracotomy and is now receiving IPPB QID. The patient's inspiratory capacity has diminished over the past several days and the patient is becoming increasingly short of breath. Chest radiograph shows left lower lobe radiodensity with a concave upper border. The respiratory therapist would conclude that the patient has developed? - correct answers pleural effusion Pressure-cycled ventilation would be LEAST appropriate for a patient with? - correct answers CO2 retention A hyperresonant percussion note is associated with which of the following pathologies? hemothorax tension pneumothorax pleural effusion pneumonia - correct answers tension pneumothorax A patient involved in a motor vehicle accident has sustained a long bone fracture and remains in traction. The patient suddenly complains of chest pain and develops tachypnea and tachycardia. The respiratory therapist should administer 100% oxygen recommend heparin. recommend streptokinase. request a chest X-ray. - correct answers administer 100% oxygen How should the respiratory therapist assemble a Bird Mark 7 respirator to deliver 40% oxygen during an intermittent positive pressure breathing treatment? Bleed in oxygen with the air-mix off 100% oxygen with the air-mix on Air-mix on and attached to a blender set at 40% Air-mix off and attached to a blender set at 40% - correct answers Air-mix off and attached to a blender set at 40% A 48-year-old woman is admitted to the coronary care unit for chest pain, dizziness and nausea. Her blood pressure is 60/40 mm Hg, respirations are 20/min. The cardiac monitor shows sinus rhythm at a rate of 50/minute with frequent multifocal PVC. The respiratory therapist should recommend administration of: lidocaine. nitroglycerin. atropine. amiodarone. - correct answers atropine. Which of the following statements is TRUE concerning positive expiratory pressure (PEP) therapy? It applies expiratory positive airway pressure (EPAP) using a one-way expiratory valve and a one-way inspiratory flow resistor. It is used for 5 - 10 minute intervals every hour. The inspiratory flow resistor prevents end-inspiratory pressures from rising above zero. It may help improve secretion expectoration, decrease hyperinflation and improve airway maintenance - correct answers It may help improve secretion expectoration, decrease hyperinflation and improve airway All of the following could cause the high pressure alarm on a volume cycled ventilator to sound EXCEPT? decrease in lung compliance. increase in airway resistance. peak flow setting of 75 L/min. acute bronchospasm. - correct answers peak flow setting of 75 L/min. A patient has performed both a forced vital capacity and a slow vital capacity maneuver with the following results: FVC 2.4 L SVC 2.18 L Which of the following statements is TRUE regarding these results? The data meets ATS-ERS standards and should be reported.
