Disadvantages of home liquid O2 systems include which of the following?1. Oxygen is lost when not used (because of venting).2. The low temperature of liquid O2 can be a hazard.3. Liquid O2 must be delivered when needed.4. Provide large volumes.

Decision made by a third party based on that individuals knowledge of the desired of the patient. 

All of the following are CMS qualifications for oxygen at home criteria except:

   A cardiopulmonary exercise evaluation is conducted on a patient before participation in pulmonary rehabilitation for what purposes? I. to quantify the patient’s baseline exercise capacity II. to develop an exercise prescription (including target heart rate) III. to determine how much desaturation occurs with exercise

All of the following are goals of Home Ventilator Care except:

   What is the ideal class size for pulmonary rehabilitation programs?

   A patient is being considered for participation in a pulmonary rehabilitation program. Which of the following test regimens would you recommend in order to ascertain the patient’s cardiopulmonary status? I. cardiopulmonary exercise evaluation II. pulmonary function testing III. cardiac catheterization

   What are some relative contraindications for cardiopulmonary exercise testing? I. severe pulmonary hypertension or cor pulmonale II. known electrolyte disturbances (e.g., hypokalemia) III. SaO2 or SpO2 less than 85% breathing room air IV. untreated or unstable asthma

   Which of the following measures during cardiopulmonary exercise evaluation are most useful in differentiating between exercise intolerance of cardiac versus ventilatory origin? I. maximum heart rate II. O2max III. PaCO2 IV. PaO2

  What are the overall goals of rehabilitation? I.  reverse the course of progression of the disease process II.  minimize the disability’s impact on the individual family  III.  maximize the functional ability of the individual
