The nurse instructs an outpatient female patient preparing for an abdominal ultrasonography that prior to the procedure, she should:
Eat or drink nothing after midnight.
Empty the bladder fully.
Drink a liter of water.
Use enemas at home to clear the bowel fully.
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.
C. Drink a liter of water. A full bladder is often necessary for abdominal ultrasonography to improve visualization of pelvic structures and other areas.
D. Use enemas at home to clear the bowel fully: Not necessary unless specified for certain types of imaging like colonoscopies.
