Final answer:
The correct position to place an unconscious patient with excessive oral secretions is the Fowler position, with the head elevated at an angle between 45 and 60 degrees.
Step-by-step explanation:
The correct position to place an unconscious patient with excessive oral secretions in order to help prevent aspiration is the Fowler position. In the Fowler position, the patient is semi-sitting with the head elevated at an angle between 45 and 60 degrees. This position helps promote drainage of oral secretions and reduces the risk of aspiration.
