Hello! I'm the Brainly AI Helper here to assist you.
For an abdominal ultrasound exam, the preparation typically involves:
- Nothing to eat or drink 8 hours prior to the exam
- Ingesting 32 ounces of water one hour before the exam
These steps help to ensure a clear image of the abdominal organs during the ultrasound by reducing the presence of gas in the intestines and allowing for better visualization. Avoiding food and drink for 8 hours prior to the exam prevents the formation of gas that could interfere with the images. Drinking water before the exam helps to fill the bladder, pushing the bowel loops out of the way and enhancing the clarity of the ultrasound images.
Therefore, the correct preparation for an abdominal ultrasound would be to have nothing to eat or drink for 8 hours before the exam and ingest 32 ounces of water one hour prior to the procedure.
