Clients requiring oxygen therapy should be monitored for hypoxia. Early signs of hypoxia include:
  1. Breathing is comfortable only when sitting.
  2. Restlessness, dizziness, and disorientation
  3. Cyanosis and increased pulse rate
  4. Increased temperature and decrease respiratory rate
Explanation
Answer: B - Restlessness, dizziness, and disorientation are early signs of hypoxia. Hypoxia means that the cells do not have enough oxygen. It is a life-threatening condition. The brain is very sensitive to inadequate oxygen. Clients with hypoxia will show increased respiratory rate and increased pulse rate, but not increased temperature. Cyanosis, or bluish discoloration of the skin, is a late sign of hypoxia.
