Eat or drink nothing after midnight.

Empty the bladder fully.

Drink a liter of water.

Use enemas at home to clear the bowel fully.

Answer and Explanation

The Correct Answer is C

A. Eat or drink nothing after midnight: Relevant for other procedures (e.g., fasting for CT or surgery), but not for ultrasonography.

B. Empty the bladder fully: Counterproductive, as a full bladder is needed for optimal imaging.
