Which of the following patients would most likely benefit from pressure support ventilation?

Which of the following are determinants of cardiac output?

A 60 year-old male is admitted to the ED with chest pain. The CBC and electrolytes are normal. The troponin level is 0.4 ng/mL. The physician should report to the patient that he is suffering from:

A patient who is receiving continuous mechanical ventilation is fighting the ventilator. His breath sounds are markedly diminished on the left, there is a dullness to percussion on the left, and the trachea is shifted to the left. The most likely explanation for the problem is that:

The primary source of infection in the healthcare setting is: 

A 65 kg spinal cord injured patient develops atelectasis. His inspiratory capacity is 30% of his predicted value. What bronchial hygiene therapy would be the most appropriate initially?

A patient in the ICU receiving mechanical ventilation underwent fiberoptic bronchoscopy during which a tissue biopsy was collected. Immediately following the procedure, the respiratory therapist notes that the peak inspiratory pressure on the ventilator has increased. Potential causes for this include all of the following EXCEPT: 

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:
