[When measuring a patient's forced vital capacity at the bedside using a portable electronic spirometer, you note that the device starts to read flow and volume before the patient actually exhales. The most likely cause of this problem is which of the following?] the flow sensor tubing not connected to computer module the patient is moving the flow sensor before starting the test the flow sensor is obstructed with packaging material the patient's lips or tongue is obstructing mouthpiece None . [You would select the semi-Fowler's position to drain which of the following lobes/segments?] Middle lobe of the right lung Posterior segments of the upper lobes Apical segments of the upper lobes Superior segments of the lower lobes None . [Once the CVP is in place, the transducer is leveled appropriately and zeroed. The monitor is showing a good waveform, with an a wave, … ] Volume overload Pulmonary hypertension VSD Pulmonary embolism None . [Which of the following would result in a an overall decrease in V/Q] Pulmonary embolus Emphysema Hypovolemic shock Pulmonary fibrosis None . [While performing nasotracheal suctioning, you note that one of the patient's nostrils is obstructed and the other is becoming traumatized. You should:] discontinue the procedure and tell the patient to cough obtain an order for postural drainage and percussion recommend inserting an endotracheal tube for suctioning recommend inserting a nasopharyngeal airway for suctioning None . [The normal range for the pulmonary artery wedge pressure (PAWP) as measured via the distal port of a pulmonary artery (Swan-Ganz) catheter is:] 20 - 30 mm Hg 6 - 12 mm Hg 10 - 20 mm Hg 2 - 6 mm Hg None . [Which of the following represents the correct pathway of impulse conduction through the heart] AV Node, SA Node, Conduction Myofibers, purkinje fibres AV Node, Bundle Branches, SA Node, Purkinje Fibers SA Node, AV Node, Bundle Branches, Conduction fibres SA Node, Bundle Branches, AV Node, Conduction myofibers None . [Which of the following chemical disinfectants would you choose if the objective were to kill both the vegetative and spore forms of bacterial pathogens?] a glutaraldehyde solution a 70% ethyl alcohol solution a quaternary ammonium solution an iodophor solution None . [You are working in the OR as an AA. The circulating Anesthetist comes in to seek your advice on the next case. Patient is 77 yo, nonsmoker, morbidly obese man (200 kg) who is suffering from severe unstable angina. This man was noted to be a difficult intubation during a previous OR case. The planned case is a triple CABG His co morbidities likely include all the following EXCEPT:] Diabetes Adrenal insufficiency Restrictive ventilatory pattern Obstructive sleep apnea None . [The primary indication for apnea monitoring is to:] prevent sudden infant death syndrome (SIDS) identify life-threatening events in neonates warn of ventilator disconnection or malfunction assess neonates for obstructive sleep apnea None . [Which of the following is responsible for maintaining lung inflation during fetal development] Amniotic fluid Fetal lung fluid Surfactant Type II Pneumocytes None . [The intra-aortic balloon pump:] Inflates during diastole, resulting in afterload reduction Inflates during diastole, resulting in increased myocardial perfusion Deflates during diastole, resulting in afterload reduction Deflates during diastole, resulting in increased myocardial perfusion None . [When suctioning a mechanically ventilated adult patient with an appropriately sized oral endotracheal tube, suctioning should be done:] quickly, taking no longer than 10-15 sec until all of the secretions are removed quickly, taking no longer than 20-30 sec until his SpO2 level drops below 90% None . [A patient breathing 100% O2 has a P(A-a)O2 of 400 torr. What is her approximate % shunt?] 0.05 0.1 0.15 0.2 None . [Which of the following types of breathing circuits would you select when assembling a noninvasive positive pressure/BiPAP ventilator?] dual-limb wye circuit single-limb circuit with expiratory balloon valve single-limb circuit with leakage-type exhaust valve single-limb circuit without any valve None .
