A client with diabetes has an order for ultrasonography. Preparation for an ultrasound includes:
A. Increasing fluid intake
B. Limiting ambulation
C. Administering an enema
D. Withholding food for 8 hours
Correct Answer: A. Increasing fluid intake
Before ultrasonography, the client should be taught to drink plenty of fluids and not void. Drink water and do not go to the toilet until after the scan – this may be needed before a scan of the unborn baby or the pelvic area. A full bladder is very important for the ultrasound exam. Empty the bladder 90 minutes before exam time, then consume one 8-ounce glasses of fluid (water, milk, coffee, etc.) about an hour before exam time.
Option B: There is no restriction for ambulation before ultrasound. Most ultrasound scans last between 15 and 45 minutes. They usually take place in a hospital radiology department and are performed either by a radiologist or a sonographer.
Option C: Enema is not necessary during an ultrasound. In some cases, you may also be given an injection of a harmless substance called a contrast agent before the scan, as this can make the images clearer.
Option D: The client should withhold voiding, not food, before an ultrasound. Avoid eating or drinking for several hours before the scan – this may be needed before a scan of your digestive system, including the liver and gallbladder.
