When the head of the bed is raised 30 degrees and the knee portion is raised 15 degrees, what is this position called?

The correct term for the position described, where the head of the bed is raised 30 degrees and the knee portion is raised 15 degrees, is known as the Semi-Fowler's position. This position is commonly used in healthcare settings to promote comfort, facilitate breathing, and prevent aspiration in patients. It allows for increased lung expansion compared to lying flat while still providing some support to the legs.

In this position, patients may feel more comfortable and can help in the management of various medical conditions, such as respiratory issues or during recovery after surgery. The slight elevation of the knees helps to reduce pressure on the lower back and provides additional comfort.

The other options do not accurately describe this positioning. High Fowler's position refers to a more upright angle, typically around 90 degrees, used for patients needing maximum lung expansion. Lateral position involves lying on the side, which does not apply here, and Trendelenburg position is characterized by having the head lower than the feet, which is not the case in this scenario.
