A 55-year-old male patient has an abnormal digital rectal examination (DRE) with a PSA (prostate-specific antigen) level of 18 ng/mL. The nurse realizes that this patient might be scheduled for which diagnostic test?
1. transrectal ultrasonography (TRUS)
2. bone scan
3. MRI
4. CT scan of the spine
Correct Answer: 1
Transrectal ultrasonography (TRUS) may be used when the digital rectal examination (DRE) is abnormal or if the PSA (prostate-specific antigen) level is elevated. In the TRUS test, a small probe is inserted in the rectum. The probe gives off sound waves that make a picture of the prostate on a video screen. Guided by this picture, the physician inserts a narrow needle through the rectal wall into the prostate gland, and the needle removes a sample of tissue for examination. The bone scan, MRI, or CT scan may be performed at a later date to determine the presence of tumor metastasis.
