C&S TMC EXAM TWO| 160 QUESTIONS| WITH COMPLETE SOLUTIONS

Prior to taking a pulmonary artery wedge pressure (PCWP) reading, the RT ensure that: correct answer: -the transducer is properly leveled and zeroed The fiberoptic bronchoscope is usually preferred device during bronchoscopy b/c its: correct answer: -flexibility The capnograph tracing above was obtained from a mechanically ventilated pt. On the basis of this tracing, the RT should: correct answer: -check the exhalation valve A RT is performing nasotracheal suctioning. During the procedure, the therapist occludes the catheter's thumb port; there is no vacuum. The therapist could do all of the following EXCEPT correct answer: -use a longer suction catheter The primary hazard of an oropharyngeal airway device is: correct answer: -the ot may gag or fight the device While manually ventilating a pt with a bag-valve resuscitator during cardiopulmonary resuscitation (CPR), the RT notices that the oxygen reservoir is missing. The therapist should conclude that: correct answer: -the FiO2 will most likely be less than 1.0 A pt with a tracheostomy tube is producing moderate amounts of thick, tenacious sputum. The best device for this pt would be: correct answer: -a heated large reservoir air-entrainment jet nebulizer Which of the following humidity devices is the most economical choice for use in an intubated, mechanically ventilated pt who only needs short-term ventilation? correct answer: -heat moisture exchanger The RT noticed that the CPAP pressure indicated on the low pressure monitor is consistently less than the preset CPAP of an infant's nasal CPAP system. Which of the following should the therapist do FIRST to correct this problem? correct answer: -tighten all connections While the RT is checking the oxygen setup of a pt on a 2L/min nasal cannula, the pt complains of not being able to detect any oxygen flow from the cannula. Which of the following actions would be appropriate? correct answer: -tighten all connections Which of the following will alter the oxygen concentration of an air-entrainment mask? 1 Increasing the flow setting-YES Occluding the air-entrainment ports-YES Altering the size of the jet orifice-YES 2 Increasing the flow setting-NO Occluding the air-entrainment ports-YES Altering the size of the jet orifice-NO 3 Increasing the flow setting-YES Occluding the air-entrainment ports-NO Altering the size of th
