New Quiz 09 Nov Welcome to your Respiratory Therapy Name: Email: [A 52-year-old patient with altered mental status requires nasotracheal suctioning. When you occlude the catheter's control port for 10 to15 seconds, you note that secretions aspirate slowly. The suction regulator is set to -75 mm Hg. To improve suctioning effectiveness, you should:] lengthen the suction time insert a nasopharyngeal airway adjust the vacuum to -120 mm Hg preoxygenate the patient None . [The patient is intubated and placed on a mechanical ventilator, during a mandatory inspiration you observe tidaling in the underwater seal of the thoracic drainage unit. Which direction is it observed?] Move towards the suction control chamber Moves toward the patient Moves away from the patient Tidaling should never be observed in the underwater seal None . [It is determined that there is no reversal agent for the sleeping pills and that the patient will need ventilatory support until the effects wear off. You are assembling and checking the appropriate equipment when you notice the self-inflating resuscitator is too slow to re-inflate when activated it in its intended way. Which of the following best explains the problem?] The gas flow to the device is set too low The reservoir bag is completely collapsed. The safety oxygen outlet valve is not opening sufficiently. The safety air inlet valve is not opening sufficiently. The duck bill valve is missing. None . [A pre-op patient with a severe, systemic disease that is a constant threat to like would be categorized as ASA:] ASA1 ASA2 ASA3 ASA4 ASA5 None . [A 23-year-old firefighter is admitted with suspected smoke inhalation. You place him on a non-rebreathing mask. What is the most appropriate method of monitoring his oxygenation?] arterial blood gas analysis co-oximetry pulse oximetry calculation of P(A-a)O2 None . [After three minutes of peak activity during an oxygen titration test, a patient's SpO2 drops from 90% to 87%. Which of the following actions is indicated?] continue the test for another three minutes at the same liter flow increment the O2 flow by 1 liter per minute and continue the test immediately terminate the test and assess the patient's vital signs increment the O2 flow by 1 liter per minute and terminate the test None . [In assessing a patient’s FVC maneuver, you note on the volume vs. time graphic display of the spirometer a 'S' shaped pattern, similar to the oxyhemoglobin dissociation curve. How would you interpret this pattern?] An obstructive pattern and acceptable test result The premature ending of expiration and an invalid test A restrictive pattern and acceptable test result Too slow a start to forced exhalation and an invalid test None . [As you are monitoring Bess you notice that her “a” wave has disappeared from her CVP waveform. This is an indication that:] The transducer is sitting below the level of the right atrium Bess has stopped breathing The tricuspid valve is incompetent causing regurgitation of blood into right atrium The atria are not contracting, Bess is in atrial fibrillation None . [The most common bulk oxygen system is the cryogenic vessel. This type of system contains liquid oxygen that can be converted to vapour. To store oxygen as a liquid, it must be kept below its ________.] Meling point Critcal temperature Latent heat temperature None of the above None . [Your patient has a #8 trach tube in situ and is ventilated in CMV-VC, RR12, Vt 500 mL, FiO2 50% and PEEP 5 cmH2O. The minimal bedside safety equipment should include] OPE, BVM, #6 trach tube, obturator OPE, BVM, #6 trach, #8 trach, obturator OPA, BVM, PEEP valve, #6 trach tube, obturator OPA, BVM, PEEP valve, #6 trach tube, #8 trach tube, obturator None . [You are called to the ER to help in the assessment and care of a patient admitted with CHF and severe pulmonary edema. While starting an intravenous line, the physician tells you to give the patient O2. You would start the following:] A nonrebreathing mask A nasal cannula at 4 L/min A simple face mask at 5 L/min A 35% air-entrainment mask None . [You are called to a stat call on the wards and perform an ABG on a patient due to decreased level of consciousness. He has a history of lung cancer and is currently recieveing treatment. You look in his chart and note he is a R2 level of care. This means] The patient has chosen comfort measure only The patient would consider chest compression as an intervention The patient does not want to go to ICU for care The patient would consider intubation as an intervention None . [An ambulatory care patient has a white blood cell count (WBC) of 20,000, along with increased sputum production. Which of the following tests would you recommend for this patient?] sputum Gram stain, culture & sensitivity arterial blood gas analysis lab spirometry (FVC volumes/ flows) bronchoalveolar lavage None . [Which of the following is associated with maternal fever and premature rupture of the membranes] Congenital anomalies Maternal diabetes Pneumonia MEC None . [Desflurane is identified by the colour:] Orange Yellow Purple Blue None . [Whole brain death indicates] Higher brain death The patient will not have spinal reflexes Higher and lower brain death The patient has a small chance of recovery None . [A physician has ordered administration of a steroid available only in a metered dose (MDI) preparation. In training the patient in its use, you cannot get her to coordinate MDI discharge with her breathing. Which of the following actions would be appropriate?] recommend discontinuing the treatments add a spacer or holding chamber to the MDI suggest an oral steroid instead of the MDI preparation recommend a bronchodilator via SVN None . [In preparation for the Apnea test the patient has a baseline ABG of pH 7.37, PaCO2 42, PsO2 90, HCO3 25, SaO2 97. The patient is prepared for Apnea Test according to the procedure 5 minutes after the Apnea Test commences another ABG is drawn. The results are pH 7.35, PaCO2 58, PsO2 55, HCO3 27, SaO2 88. The patient has not made any spontaneous efforts. What does this ABG indicate] Apnea test is negative Apnea test should be discontinued Apnea test is positive and the patient cannot be an organ donor The patient was not preoxygenated adequately None . [Which of the following describes a mode of ventilation that would best preserve tidal volume when a patient’s lung/thorax compliance increases?] Pressure cycled Pressure limited, time cycled mode Volume limited, time cycled mode Pressure limited, flow cycled mode None . [In compensating for heart failure, the body will:] Increase blood volume Dilate the peripheral vasculature Decrease the HR Increase the urine output None . Time's up
