  B) The chest tube should not be separated from the drainage system unless clamped.
  C) A nasal cannula should be used to administer oxygen when cleaning the opening.
  D) A secondary source of oxygen should be available in case of power failure.

Question 2

Answer to Question 1

B
Feedback:
When using water-seal chest tube drainage, the nurse should never separate the chest tube from the drainage system unless clamped. Even then, the tube should be clamped only briefly. When using an oxygen concentrator as a source of oxygen, the nurse should clean the filter regularly to avoid an unpleasant taste or smell. A secondary source of oxygen should also be available in case of a power failure. When cleaning a transtracheal catheter, oxygen needs to be administered with a nasal cannula.

Answer to Question 2

7.35; 22
The normal arterial blood pH value is 7.35 to 7.45 (acidic is less than 7.35, and alkalotic is greater than 7.45). The normal range of bicarbonate (HCO3-) is 22 to 26 mEq/L. Levels below 22 mEq/L usually indicate metabolic acidosis.
