These findings are consistent with Answer heart failure A patient is admitted to the ED following a motor vehicle accident. On physical exam, the respiratory therapist discovers that breath sounds are absent in the left chest with a hyperresonant percussion note. The trachea is shifted to the right. The patient's heart rate is 45/min, respiratory rate is 30/min, and blood pressure is 60/40 mm Hg. What action should the therapist recommend first? Answer Needle aspirate the 2nd left intercostal space All of the following strategies are likely to decrease the likelihood of damage to the tracheal mucosa EXCEPT Answer using a low residual volume, low compliance cuff A 52 year-old post-operative cholecystectomy patient's breath sounds become more coarse upon completion of postural drainage with percussion. The respiratory therapist should recommend Answer deep breathing & coughing to clear secretions A 65 kg spinal cord injured patient develops atelectasis.

Answer IPPB A healthy adult female can exhale what portion of her forced vital capacity in the first second? Answer 70% A patient on VC ventilation demonstrates auto-PEEP on ventilator graphics. Which of the following controls, when adjusted independently, would increase expiratory time? 1. Tidal volume 2. respiratory rate 3. inspiratory flow 4. sensitivity Answer 1, 2, and 3 only Which of the following would be the most appropriate therapy for a dyspneic patient who has crepitus with tracheal deviation to the left and absent breath sounds on the right? Answer insert a chest tube Following cardiac surgery, a 55 year-old patient has the following ABG results: pH 7.50, PaCO2 30 torr, PaO2 62 torr, HCO3 25 mEq/L, SaO2 92%, HB 14 g/dL, BE +2. Venous blood gas results are pH 7.39, PvCO2 43 torr, PvO2 37 torr, and SvO2 66%. Calculate the patient's C(a-v)O2. Answer 5.0 vol % A patient on VC, SIMV with a VT of 500 mL has a PIP of 25 cm H2O, Pplat of 15 cm H2O and PEEP of 5 cm H2O. What is the patient's static lung compliance? Answer 50 mL/cm H2O Immediately after extubation of a patient in the ICU, the respiratory therapist observes increasing respiratory distress with intercostal retractions and marked stridor. The SpO2 on 40% oxygen is noted to be 76%. Which of the following would be most appropriate at this time? Answer Reintubation Which of the following patients would most likely benefit from pressure support ventilation? Answer A patient on SIMV with a mandatory rate of 12/min and total rate of 24/min. A patient receiving mechanical ventilation has developed a temperature of 99.9° F with purulent secretions over the last 12 hours. The respiratory therapist has also noted a steady increase in peak inspiratory pressure. What initial recommendation should be made to address these changes? Answer obtain a sputum gram stain Which of the following information may be obtained from a FVC maneuver during bedside pulmonary function testing? 1. FEV1 2. PEFR 3. FRC 4. RV Answer 1 & 2 only The respiratory therapist provides education for a patient who is being discharged home on aerosol therapy.
