Answer:
B. Foley catheter placement.
Step-by-step explanation:
This patient is likely suffering from acute urinary retention caused by benign prostatic hyperplasia (BPH).
As an enlarged prostate obstructs urine flow, the bladder cannot fully empty, leading to urinary symptoms and potential complications. The best immediate management is placement of a Foley catheter to drain the bladder and relieve obstruction. This provides temporary relief while allowing us to monitor urine output and obtain samples for analysis.
Hope this helps you! :)
