A client is having an abdominal ultrasound and wonders why the physician did not order a CT scan or MRI. The nurse's best explanation for the choice of procedure is
a. "An ultrasound is far less expensive than CT or MRI."
b. "There is less need for dye contrast and fewer complications."
c. "Ultrasounds can be done more quickly and are best for screening."
d. "You can correlate physical and ultrasound findings during the exam."

Ultrasound can enhance physical examination because findings can be correlated with physical structures while the client is on the examining table. Ultrasound is faster and cheaper than CT or MRI, but each test has its own benefits and indications. Ultrasound is not used primarily for screening.
