Final answer:
To prevent aspiration when feeding a patient, it is important to position them in an upright position, which minimizes the risk of food or liquid entering the respiratory tract.
Step-by-step explanation:
To prevent aspiration, it is recommended to place a patient in an upright position and then assess before providing any feed or drink. The upright position is essential as it helps in preventing the food or liquid from entering the respiratory tract, which can cause aspiration pneumonia. Positions such as supine, Trendelenburg, and left lateral are not preferable for feeding because they increase the risk of aspiration.
