Welcome to your Respiratory Therapy Name: Email: [How is the percentage of functional hemoglobin that is saturated with oxygen determined via pulse oximetry?] The percentage of infrared light that reaches the photodector reflects SpO2 The sum of the amount of red and infrared absorbed by the tissue determines the SpO2 The ratio of the red and infrared light that reaches the photodiodes signified SpO2 The percentage of red light that lands on the photodiode represents oxygen saturation as None . [To measure the amount of auto-PEEP present in a patient receiving ventilatory support, you would:] measure pressure during an end-inspiratory pause measure pressure at volume increments using a super syringe measure pressure during an end-expiratory pause measure expiratory flow before and after bronchodilator None . [The CARTA code of Ethics instructs us to “guard against conflicts of professional interest” and to specifically consult the _______________________ to prevent a real or perceived conflict of interest? Who is the individual/or department that Alberta RRTs are to consult? ] The Alberta Health The CARTA Registrar The alberta department of justice Your employer None .

[An ICU patient receiving ventilatory support is suspected of having a tension pneumothorax. Which of the following would you recommend?] switch to bag-valve manual ventilation perform tracheobronchial suctioning obtain arterial blood gas for analysis get chest X-ray/prepare for thoracostomy None . [Which of the following events cause cessation of right to left shunting through the foramen ovale] Increased levels of PaCO2 in fetal blood Decreased SVR Increased SVR Decreased levels of PaO2 in the fetal blood None . [Which of the following is incorrect in regards to the body’s normal flora] A.They will not cause harm as long as they stay in the expected site B.They are different from person to person for a given site If they are removed from a site, opportunistic microorganism may take over They are found on the skin and some mucous membranes A and B are correct None . [On assessment of an acutely ill patient, you note all the following in the region of the left lower lobe: decreased expansion, a dull percussion note, and the absent of breath sounds/tactile fremitus. You also observe a shift in the trachea toward the left, more prominent during inspiration. These findings suggest:] left-sided obstruction/atelectasis left-sided pneumothorax left-sided consolidation left-sided pleural effusion None . [Dry mucous membranes and decreased U/O are characteristics of what degree of fluid deficit] Mild Moderate Severe V. severe None . [When performing spirometry on an adult patient, which of the following would indicate invalid/unacceptable test results?] back extrapolated volume 300 mL time to peak flow 100 msec forced expiratory time > 6.0 sec repeat FVCs match within 150 mL None . [Your patient is currently on an SBT. Approx 15 minutes into the trial you observe that his RR has increased from 18 to 25 and he seems to be working using more accessory muscles to breathe. In that same amount of time your volumetric capnograph has shown an increase in VtCO2. What should you do for patient? ] This is a normal response to the imposed WOB of the SBT. Continue SBT This is an abnormal response to the imposed WOB of the SBT. Discontinue the SBT The increase in VtCO2 correlates with an increase in PaCO2 and the patient is failing. Discontinue the SBT The VtCO2 is an indication of how much CO2 is present in exhaled gas at any given time and normally increases from the start of exhalation to the end of exhalation. Continue the SBT None . [Nerve blocks fall under the category] Specific anesthesia Neuroaxial anesthesia Regional anesthesia Spinal anesthesia None . [Hyperventilation as a therapy for an acute head injury is used for its _____ effects and _____ cerebral blood flow.] Vasodilatory, increases Vasoconstrictory, increases Vasodilatory, decreases Vasoconstrictory, decreases None . [A doctor prescribes heliox therapy for a patient admitted to the Emergency Department with an acute exacerbation of asthma. A full cylinder of 70% helium and 30% O2 is at the bedside with a standard nasal cannula attached. You should:] administer the therapy with the cannula as ordered administer the therapy and then draw an ABG obtain a nonrebreathing mask and administer the therapy obtain a venturi mask and administer the therapy None . [Which of the following does not cause an increase in measured pcwp?] Hypervolemia Left ventricular failure Mitral stenosis 3rd spacing None . [In a volume controlled breath, as the patient’s compliance increases the pressure _______ and the tidal volume _________] Decrease, Decrease Increase, Remain the Same Decrease, Increase Decrease, Remains the Same None . [During an allergic reaction there is an increase in circulating antibody] IgA IgD IgE IgG IgM 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 . [While suctioning an adult patient receiving ventilatory support, you note the heart rate decreases abruptly from 92 to 55/min. Which of the following actions could help prevent or minimize this problem?] Recommend a bolus of atropine before suctioning Instill lidocaine (Xylocaine) into the trachea before suctioning Increase the FIO2 to 1.0 for at least 30-60 seconds before suctioning Give the patient 2 MDI puffs of beclomethasone before suctioning None . [Which of the following would you recommend to help guide a physician in locating the appropriate needle insertion site for thoracentesis performed at the bedside?] ultrasound CT scan thoracic MRI bronchoscopy None .
