The correct answer is: B. Decrease in pulse rate and respirations.
Explanation:
1. Hypoxia is a condition where there is a deficiency of oxygen reaching the tissues of the body.
2. Signs of hypoxia include disorientation, confusion, apprehension, anxiety, and cyanosis (bluish discoloration) of the skin, mucous membranes, and nail beds.
3. A decrease in pulse rate and respirations would not typically be signs of hypoxia. In fact, in hypoxia, the body tends to increase the pulse rate and respiratory rate to compensate for the reduced oxygen levels.
4. Therefore, if someone is experiencing hypoxia, you would expect to see an increase in pulse rate and respirations rather than a decrease.
