The MKSAP Challenge
A 52-year-old man presents as a new patient requesting an annual examination and a serum prostate-specific antigen (PSA) measurement. He exercises, does not smoke and drinks alcohol infrequently. His medical records disclose well-controlled hypertension, a negative exercise tolerance test four years ago, and various laboratory evaluations, all of which were normal. His only medication is atenolol.
Previous health maintenance included a colonoscopy two years ago, and serum PSA values of 4.2 ng/mL one year ago and 3.8 ng/mL two years ago. The patient recalls his prior physician telling him the value was borderline and recommending a repeat measurement in one year.
Physical examination, including digital rectal examination, is unremarkable. Serum PSA value is 5.0 ng/mL.
Which of the following is the most appropriate next step in the management of this patient?
A. Prescribe tamsulosin therapy
