You are caring for a 33-year-old male who has come to the clinic for a physical examination
He states that he has not had a routine physical in 5 years. During the examination the physician finds that digital rectal examination (DRE) reveals "stoney" hardening in the posterior lobe of the prostate gland that is not mobile. The nurse recognizes that the observation typically indicates what?
A) A normal finding
B) A sign of early prostate cancer
C) Evidence of a more advanced lesion
D) Metastatic disease
Ans: C
Feedback: Routine repeated DRE (preferably by the same examiner) is important, because early cancer may be detected as a nodule within the gland or as an extensive hardening in the posterior lobe. The more advanced lesion is "stony hard" and fixed. The scenario does not describe metastatic disease.
