Final answer:
The correct answer to the symptoms described is hypoxia, which is a condition characterized by a deficiency of oxygen reaching the tissues causing various symptoms including bluish discoloration of the skin and increased breathing rate.
Step-by-step explanation:
The signs and symptoms described, such as bluish skin, lips, mucous membranes, and nail beds, increased rate and depth of breathing, fatigue, disorientation, dizziness, confusion, and restlessness, are indicative of hypoxia. Hypoxia is a condition where there is a deficiency in the amount of oxygen reaching the tissues. It should not be confused with cyanosis, which is the visible bluish discoloration of the skin and mucous membranes but is a symptom that can occur as a result of hypoxia. Tachypnea is the increased rate of breathing, which can be a body's compensatory response to hypoxia. Bradypnea, on the other hand, is a decreased breathing rate and does not match the symptoms described.
