What is the recommended patient preparation for an abdominal ultrasound?

Drinking plenty of water before the exam
Fasting for 6-8 hours prior to the exam
Taking a laxative the night before
Arriving with a full bladder

The correct answer is: Fasting for 6-8 hours prior to the exam

Fasting for 6-8 hours prior to an abdominal ultrasound is the recommended preparation because it significantly improves the quality of the images obtained during the examination. When the patient fasts, the stomach and intestines are less likely to contain food or gas, which can obscure visualization of important abdominal structures such as the liver, gallbladder, pancreas, and kidneys. A clearer view is essential for obtaining accurate measurements and detecting any abnormalities. This fasting period ensures that the sonographer can assess the organs effectively, leading to better diagnostic outcomes. Other methods of preparation, while important for specific types of examinations, do not provide the same level of benefit in terms of image clarity for a standard abdominal ultrasound.
