[Intraoperative patients with uncontrolled hypertension are at risk of:] Intraoperative hypotension Post op DVT Malignant hyperthermia Aspiration None . [A premature infant receiving positive pressure ventilation exhibits acute respiratory distress, asymmetrical chest motion and hypotension. Which of the following procedures would you initially recommend?] chest transillumination arterial blood gas A-P chest radiograph capillary heal stick 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 . [Which of the following is considered the main mechanism by which hypertonic aerosols aid mucociliary clearance?] Increased stimulation of the irritant cough reflex Alterations of peak insp airway resistance Enhanced sensory somatic nervous impulses Altering the pH level 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.

[When using a numeric rating scale (NRS) to quantify a patient's pain intensity, the patient reports a level of 5 on the 10-point scale. You note that his last rating was a level of 2. Based on this rating and the reported change, you should:] Immediately report the findings to the patient's physician Record your findings in the respiratory care progress notes Repeat the assessment to see if the results are reproducible Advise the patient to try and relax and focus on the positive None . [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 . [What is the typical frequency range available for ventilating patients via a high frequency oscillator?] 40-60/min 60-100/min 100-200/min 200-900/min None . [A patient is receiving volume controlled A/C ventilation. Which of the following changes would occur if the patient's compliance were to decrease?] the expiratory time will increase the flow rate will decrease the system pressure will increase the delivered volume will decrease None . [In reviewing the chart of a 55 year-old male patient, you note the following symptoms: obesity, loud snoring and insomnia. These findings are most consistent with which of the following diagnoses?] pulmonary emphysema acute asthma Guillain-Barré syndrome obstructive sleep apnea None . Time's up
