A patient in the MICU who suffered a near-drowning incident is on pressure support ventilation at 20 cmH2O with a tidal volume delivery of 10 mL/kg. The patient has been on this mode for the last 48 hour. When you enter his room, you notice that the patient suddenly exhibits refractory hypoxemia, decrease in lung compliance and tachypnea. A STAT CXR reveals pulmonary infiltrates in all lung fields. Which of the following modes of mechanical ventilation would be appropriate at this time?

While assisting the physician with a bedside bronchoscopy, the patient begins to bleed at the site of the needle aspiration. Which of the following medications should be given to the physician at this time?

Identify structures D on the model below.

A postoperative patient complaining of dyspnea is found to have tachypnea and tachycardia, and is somewhat confused. Breath sounds reveal end inspiratory crackles in both lung bases. An arterial blood gas is drawn and reveals the following: pH 7.49; partial pressure of carbon dioxide (PaCO2) 33 mm Hg; partial pressure of oxygen (PaO2) 51 mm Hg; arterial oxygen saturation (SaO2) 87%; bicarbonate (HCO3-) 25 mEq/L while on a 30% air entrainment mask. The most appropriate respiratory therapy intervention includes which of the following?

Calculate the tubing compliance (CT) when the measured volume is 150 mL and the static pressure is 53 cm H2O.
