A “ventilator bundle” may include which of the following? 1. Keeping the head of the bed at 30 degrees from the horizontal 2. Changing the ventilator circuits every 48 hours 3. Using a Heat Moisture exchange 4. Using noninvasive positive pressure ventilation (NPPV) whenever possible

Calculate the arterial oxygen content for a patient with the following arterial blood gas measurements: Hgb = 9g%, arterial oxygen saturation = 96%, arterial partial pressure of oxygen (PaO2) = 97 mm Hg.

During bronchoscopy, bleeding may be stopped by all of the following techniques except:

Venous return is least impaired by which of the following modes of ventilation?

Which of the following measures should be used in assessing the adequacy of a patient’s alveolar ventilation? 1. PaO2 2. Arterial pH 3. PaCO2 4. HCO3–

During transport of a mechanically ventilated patient, monitoring must be done:

During assessment of Mr. Fagan, the therapist obtained these systemic blood pressure readings: systolic 95 mm Hg, diastolic 49 mm Hg. the therapist should report the finding to his physician as:

Your patient has evidence of retained secretions and you have an order to administer a mucolytic agent. To monitor the patient for bronchospasm during aerosol drug therapy, what actions should the RT take?

You have a 70 kg male patient on the surgical floor. He is currently using 50 LPM at 50% high-flow nasal cannula. The patient is in respiratory distress and requires support. The physician asks for your recommendations for the initial ventilator settings.
