D. disoriented. 9. The respiratory therapist is evaluating a patient and observes a six second capillary refill time. This indicates the patient A. has pulmonary edema. B. has inadequate perfusion to the extremities. C. has adequate pulmonary perfusion. D. has an increased cardiac output. 10. While conducting a pulmonary evaluation on a patient, the respiratory therapist auscultates diminished breath sounds on the right side and palpates the trachea being shifted toward the right side. The therapist should suspect which of the following? A. right-sided tension pneumothorax B. massive atelectasis of the right lung C. left-sided pneumothorax D. pleural effusion of the left lung 11.

I only B. III only C. I and II only D. I and III only 13. A patient in the cardiac care unit is hemodynamically unstable with fluctuating arterial blood pressures. Which of the following should the respiratory therapist recommend to best monitor this patient’s hemodynamic status? A. pulse oximeter B. radial artery catheter C. radial artery puncture for ABGs D. echocardiogram daily 14. The respiratory therapist is reviewing the chart of a patient in ICU who has a Swan-Ganz catheter in place. Which hemodynamic value would best determine the extent of the patient’s left heart failure? A. central venous pressure (CVP) B. pulmonary artery pressure (PAP) C. pulmonary capillary wedge pressure (PCWP) D. mean arterial pressure 15. To most effectively monitor the hemodynamic status of a patient with ARDS who is being mechanically ventilated, the respiratory therapist should recommend which of the following? A. Swan-Ganz catheter B. EKG monitor C. peripheral arterial line D. pulse oximeter 16. A 28-week-old neonate is suspected of having a pneumothorax. Which of the following should the respiratory therapist recommend to help diagnose if this condition is present?
