Final answer:
Paul Greer was admitted for a radical prostatectomy to treat his stage III prostate cancer. His difficulty voiding and the aggressive nature of the cancer are the primary reasons for the surgery, not his history of hypertension or negative lymph node biopsy.
Step-by-step explanation:
The reason for Paul Greer's admission is for a radical prostatectomy. This surgical procedure is a treatment for prostate cancer, particularly when the cancer is aggressive and could potentially spread to other parts of the body.
In Paul's case, he was diagnosed with stage III prostate cancer, which is typically more advanced and requires treatment beyond active surveillance due to the higher likelihood of spreading and causing significant health issues. Although Paul also has a history of hypertension and a past smoking habit, these are not the direct reasons for his current admission. His decision to seek care was propelled by his difficulty voiding, which is a common symptom of prostate issues.
