A patient is admitted to the ICU after a positive exercise treadmill test with a diagnosis of CAD and stable angin
 
  a. Radiographic test show that the patient has blockage in the left main coronary artery and four other vessels. The nurse anticipates that the patient will be scheduled for
 
  a. medical therapy antianginal medications.
  b. PCI.
  c. TAVR.
  d. CABG.

Question 2

Preset positive pressure used to augment the patient's inspiratory effort is known as
 
  a. positive end-expiratory pressure (PEEP).
  b. continuous positive airway pressure (CPAP).
  c. pressure control ventilation (PCV).
  d. pressure support ventilation (PSV).

Answer to Question 1

D
Early studies demonstrated coronary artery bypass graft surgery was more effective than medical therapy for improving survival in patients with left main or three-vessel coronary artery disease and at relieving anginal symptoms. Medical therapy is recommended if the ischemia is prevented by antianginal medications that are well tolerated by the patient. Surgical revascularization has been shown to be more efficacious than percutaneous coronary intervention in patients with multivessel or left main coronary disease. Transcatheter aortic valve replacement is a transformational therapy for patients who have severe aortic stenosis but who are extremely high-risk surgical candidates or who are inoperable by virtue of associated co-morbidities.

Answer to Question 2

D
Preset positive pressure used to augment the patient's inspiratory efforts is known as pressure support ventilation. With continuous positive airway pressure, positive pressure is applied during spontaneous breaths; the patient controls rate, inspiratory flow, and tidal volume. Positive end-expiratory pressure is positive pressure applied at the end of expiration of ventilator breaths.
