Welcome to your Respiratory Therapy Name: Email: [You note that the reading from a pulse oximeter equipped with a disposable finger probe has decreased from 93% to 71%, without a change in FIO2 or patient condition. The most likely cause is that the:] oximeter unit needs to undergo recalibration probe is overheated and should be moved probe/probe site needs to be warmed to 42 degrees Celsius probe or probe cable is malfunctioning None . [During intubation in the OR, the patient goes into laryngospasm. Which of the following is an appropriate action?] Continue to carefully advance the ETT through the glottis opening Administer IV bolus of 40mg of propofol Cricothyrotomy Administer narcan None . [The u-receptor that moderate pain relief observed with Oxycodone can also cause] Increase respiratory effort Increased INR Euphoria Diarrhea None . [Which of the following arterial blood gas results would be most representative of a patient who has advanced, but stable, COPD breathing room air? pH PaCO2 PaO2 torr torr A 7.37 41 55 B 7.38 59 56 C 7.41 45 79 D 7.50 56 57] A B C D None . [You have stabilized a bradycardic patient in third degree heart block using TCP at a rate of 60 bpm. Mechanical capture has been confirmed. The patient remains hypotensive. Your next action would be to:] Increase the mA setting Increasing the rate of pacing Start an infusion of epinephrine Cardiovert the patient at 50 J None . [You are taking a patient to X-ray. The patient is on 4 LPM O2 per nasal cannula. There is a D cylinder with 1200 psi. How long will the flow last? (Use the American / Egans textbook conversion factor.)] 32 mins 35 mins 48 mins None of the above None . [A term neonate presents with central cyanosis, gasping respiration and a HR of 90. What is an appropriate action?] Observe for 30 seconds to assess if the baby is experiencing primary apnea Provide CPAP with neopuff Frimly shake the baby to stimulate Commence positive pressure ventilation None . [A patient is receiving volume control A/C ventilation. The patient has become increasingly agitated and the end-tidal CO2 has decreased from 39 to 28 torr over the last 2 hours. Which of the following is the most likely cause?] increased cardiac output mainstem intubation high body temperature increased ventilation None . [All of the following are common causes of fluid depletion (dehydration) in patients EXCEPT:] diarrhea/vomiting hemorrhage renal failure sweating/fever None . [What type of lung unit(s) would result in a long time constant] Decreased airway resistance Decrease Elastance Decrease Compliance - causes a decrease in TC Decreased Surfactant - causes a decrease in C None . [Which of the following compliacations is the result of an ETT] Tracheal Ulcers Tracheal Cartilage Loss Tracheal Malacia Tracheoesophageal fistula All of the above None . [T/F Rapidly achieving alveolar concentration of volatile agent and size of FRC has an inverse relationship] True false None . [While doing a ventilator check on a patient receiving volume control ventilation you observe a substantial drop in pressure on the pressure vs. time waveform after triggering of most machine breaths. Which of the following best explains this finding?] improper sensitivity setting presence of auto-PEEP/air-trapping a leak in the patient-ventilator system inadequate inspiratory flow setting None . [What could cause blunting of the costophrenic angle in this case?] Pneumothorax Pneumomediastinum Hemothorax None . [During ventilation of a child with a bag-valve resuscitator, the pressure relief valve/pop-off continually activates. Which of the following should be your first action?] Switch to a gas-powered resuscitator Bypass the pressure relief valve Squeeze the bag more slowly Lower the PEEP valve level None . [Where is the majority of extracellular fluid located:] Interstitial space Intravascular space Plasma Within the blood vessels None . [For which of the following purposes would you recommend pressure support ventilation (PSV)?] to help manage hypoxemic respiratory failure to control a patient's minute ventilation to increase the functional residual capacity to decrease work of breathing caused by ET tubes None . [Train of four is used to monitor:] Heat condition Level of consciousness Neuromuscular blockade MAC level None . [A physician orders an FIO2 of 0.50 for a premature infant in an Isolette. To deliver the prescribed FIO2, you should select:] a nonrebreathing mask at 5 L/min an oxygen hood with blender an infant nasal cannula at 1 L/min a simple mask at 6 L/min None . [An intubated patient with COPD who is in acute respiratory failure requires a ventilator. To optimize support of this patient you would recommend a ventilator capable of:] airway pressure release ventilation pressure support with adjustable off-cycling mandatory minute ventilation high frequency oscillation ventilation None .
