Water has a myriad of uses around the globe.  Globally, which of these accounts for the largest percentage of water consumption?

A patient who is receiving mechanical ventilation post cardiac arrest has a PA catheter placed in the right subclavian vein and has the following measurements recorded:PCWP:         7 mmHgmPAP:         35 mmHgHR:              115 bpmB/P:              95/45 mmHgC.O.:             3.9 L/minBSA:             2.3 m2Which hemodynamic values would be below normal based on the data?I. cardiac index (C.I.)II. stroke volume (SV)III. mixed venous saturation (SvO2)IV. central venous pressure (CVP)

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?

A patient’s baseline arterial blood gas (ABG) reveals a partial pressure of oxygen (PaO2) of 78 mm Hg while receiving 35% supplemental oxygen. What should the ventilator fractional inspired oxygen (FIO2) be set at to obtain a target PaO2 of 95mm Hg?

BONUS: An RT has just intubated a patient with the assistance of another respiratory therapist who is monitoring a capnograph during the procedure. Throughout the intubation procedure and after insertion of the ETT the ETCO2 monitor maintained a reading of 0%. What interpretation can be made at this time?

BONUS: During a fixed-wing transport of a mechanically ventilated patient, it is imperative the RT consider that:I. as altitude increases, trapped gas will decreaseII. as altitude increases, trapped gas will increaseIII. the FiO2 decreases with increased altitudeIV. the delivered tidal volume from the ventilator must be doubled for every 5000 feet of       increase in altitudeV. the PaO2 decreases with increased altitude

Fetal lung maturity on a new born can be evaluated to be normal by which of the following?

A post-op patient is receiving 50% oxygen via an air-entrainment nebulizer. The SpO2 has decreased to 90% and the minute ventilation is 13.9 L/min. Which of the following would increase the total flow to the patient to maintain an oxygen delivery of 50%?I. Bleed in 5 L/min to the air-entrainment nebulizerII. change to a dual flow nebulizer device with both air-entrainment nebulizers set at 50% with     15 L/min flowIII. Switch to a gas-injection nebulizer (GIN) with an oxygen flow rate set at 22 L/min and an       air flow meter set at 37 L/min

A patient who is mechanically ventilated is suspected of having a bronchopleural fistula. The respiratory therapist on duty is asked to make a recommendation for a different mode of ventilation. Which of the following should the RT recommend?

An intubated patient with Chronic Obstructive Pulmonary Disease (COPD) is breathing on pressure support ventilation (PSV) 13 cm H2O with positive-end-expiratory pressure (PEEP) 5 cm H2O and a flow cycle setting of 25%. The pressure-time scalar shown in the figure is evaluated by the respiratory therapist. What action should the respiratory therapist take at this time?
